Having multiple routers in the same local network

(I apologize for any incorrect terminology. )

I have a router A in room 1 connected to the outside network and a router B in room 2 not connected to the outside network. I want to set up my router B so that room 2 can have the fastest connection possible.

I've tried having my router B join and extend my internet from router A, however the connection is pretty weak between the two routers and due to the layout of my house it would not be possible to add any additional routers in between. I have two solutions in mind but I don't know if they are feasible:

  1. I could connect my router B to a different ethernet socket in room 3. The ethernet sockets in rooms 1 and 3 are connected to different ports on my modem. When I try setting up router B (connected to ethernet socket in room 3) as a new network, the networks are not on the same local network. So for example devices connected to router A have IPs 192.168.2.x, whereas devices connected to router B have IPs [192.

Weird Network Behaviour

What started as a my Unifi AP acting up has just got weirder and weirder. Wi-fi started acting up a bit, I had a LAN connection but I couldn't connect to anything on the internet. Hard wired connections all fine. Rebooted it, provisioned it etc etc. Nothing doing.

Then I couldn't log into my router (pfsense) anymore from a hard connection. Tried rebooting, no joy, every time I tried to log into the WebGui I got error connection closed. Could ping it, and everything else on the LAN.

Plugged into the console on the router. All looked fine. Tried plugging direct into the LAN port, wahey all fine.

Bit of trial and error testing and it seems like when the router LAN is plugged into port 2 on my main switch (TP Link SG 16P Smart), only port 1 would let me talk to the router. Every other port gave me connection refused. Temp swapped a little 5 port in and patched in and everything seemed working again. Bricked switch maybe I thought, but seemed weird it would route pings fine.

Can I get help here with my home network?

Hoping to get some help, as I've exhausted everything I could think of.

Long story short, when trying to pin down why some files were getting corrupt when being moved across my home LAN, I started to Zip a test file and move that - then use 7Zips test process to see if it has been moved without corruption each time I test.

I moved a 3Gb zip file to some attached storage on an Nvidea Shield, and it seems fine - I've got the share mapped, and I can run 7Zip test on it, and its fine.

But if I copy it back to my Win10 PC desktop, the 7zip test fails instantly.

The network is:

Win10 Laptop > Modem/Router > Netgear 5 port unmanaged Gb switch > Nvidia Shield

About 10 months ago, this was working perfectly, but then it didn't get used for a long time - then just in the last week or so I've started using it again - but have ran into this issue with files being corrupted on the Sheild's attached (USB) HDD.

Any thoughts on what I can do to troubleshoot this?

Home network. Router did not move, but I turned the desk it was on 90 degrees. Wireless is now very spotty on other side of the house

I used to get spotty reception on one side of my house. I added a Wi-Fi extender and it was better.

I upgraded to a newer ASUS router and the wireless in my house worked flawlessly. My ASUS router is plugged into my Windstream router. The wireless is on for the ASUs router and I turned it off for the Windstream modem/router as it interferes with the ASUS wireless and slows it down. I have double checked and the wireless on the Windstream router is turned off and I do not see it in my wireless signals.

A week ago, my wife rearranged our home office where and turned the desk the router was on by 90 degrees. The router is in almost the exact same spot as it was before the desk was turned.

My wireless on the other side of my house is spotty again. I turned the router so that it is exactly like it was before. I aimed the Antennas at the other side of the house and nothing is working.

Do any equipment vendors run network traffic over this address range by default? Googling hasn't told me much.

Edit: Looks like local ISP configuration issue. I've contacted them to investigate private addresses showing up over the internet.

High latency on all my network when my PS4 is running

Hello guys,

I've got a question about something strange that occurs when I start playing on my PS4.

My raspberry Pi 3 is always "monitoring" my network latency with somkeping.

So, when I start my PS4 I can cleary see that the latency increase a lot (and I can't play smoothly online) :

https://preview.redd.it/4o3loxjokwh41.png?width=699&format=png&auto=webp&s=4ef396fd1c9fd5cd8e4d853a0d87c5e2f064281b

I have multiple devices that are always running, none of them cause this kind of strange thing.

The PS4 is in a DMZ behind a switch connected to my standard ISP modem/router.

The rapsberry is connected to the same switch.

Do you have any idea why this specific device causes latency to all my network ?

Network congestion and live sports broadcasting.

Hello. I try to better understand how live sports broadcasting affects network congestion.

If I and the folk in a neighboring apartment watch the same game live, broadcasted by the same service (e.g. Hulu LiveTV) does it make a double network load? Or our local router gets only one signal for us both and then split it and send it to our receivers separately? In short, does the network congestion depend on how many people in the neighborhood watch the same live game from the same broadcasting service, or the whole neighborhood gets the same signal from the server?

Any help is highly appreciated.

Split Network for Smart Home Devices?

I'm wondering if there's any benefit at "splitting" my home network to accommodate a bunch of smart home devices, and to potentially solve a problem where my network seems to lose connection with laptops recently.

Setup:

I have a large house, with few to no neighbors so lots of wide open network channels (checked on Acrylic). I currently run two router/APs, one is a dual band WNDR series, and the other is tri-band TrendNet TEW-828DRU. I have 5 non-overlapping bands set up, 3 5GHz, 2 2.4Ghz. I run DD-WRT on both, and chain one from the other, one the WNDR serving as the main address server, etc. All run the same SSID, one network.

For devices, there's a few laptops and a wired PC, a few smart phones, a not often used printer. But over time, I've added 3 Chromecasts / Chromecast audio, 5 google home minis, 4-6 smart outlets, a Google Nest, and half a dozen smart bulbs.

Looking for a way to create diagrams of networks

Hey guys,

We do small jobs that mostly require 8 or 24 port switches (rarely 48 port), as well as a corresponding patch panel.

I am looking for some sort of software where we can have the switch/patch panel layout, where each port can be color coded, labeled and "routed" in a way that is easy to read, modify, and "graphic friendly". Is there anything out there like this.

I guess would could use an image of the switch/patch panel layout and Photoshop what we need, but I am hoping for a more streamlined way. We could also fiddle with some flowcharts, but I feel that is overkill.

Can I make a seamless wireless network with a home router and an access point?

I know what an IP adresss is, but I don't know much about networking. I tried following guides, naming the networks the same with the same encryption/passwords, etc. Nothing really worked.

Does the router and AP need something special for the transition to be seamless?

I have a 2 storey home, and lead walls apparently, so my idea was to use the router for the top floor and an AP in the lower floor.

What happens is that cellphones etc. still get a tiny bit of signal, not enough to really work, but not enough to disconnect completely, so when I switch floors, I end up with 1% useless instead of seamlessly picking up the other device.

My router is a TP link TL-WR941HP.

The access point is a TP link TL-WA901ND.

I'm connecting the AP to one of the ethernet ports on the router (I have ethernet between floors). Tried all the configurations I could think of that made sense on the AP.

Any advice is appreciated!

I'd consider myself tech literate, although it was over a decade ago that I was seriously into PC's... but I feel like you used to be able to have a small window running on your desktop that would give you a realtime view of your internet connection and speed. Did I just make this up?

Segment home network with bandwith control?

Hello there,

three floors in a house, each must have internet access. Control over bandwidth usage possible?

first of all, I should mention what I'm working with. There are 3 floors in a building and I want to give each of these floors access to the internet via one modem. I would like those 3 floors to have seperate networks but thats not necessary. Should I use VLANs or something else?

Is it possible to have some kind of bandwith control to the internet? Like if every network has traffic (for example downloading some large files) that each network has a limited bandwidth (floor one has to get at least 20%, the other 2 floors at least 40% each) but if only one floor has traffic, it gets all the bandwidth available. Is that even possible?

What's the most cost effective way of doing this, or something similar to this?

Home network from scratch

I'm about to wire my small house for ethernet. It has been in the plans for a while, and now I have the $$. I'd like to get it right, the first time.

The plan -

4 jacks to living room. (25-30' run) for Apple TV, tv, wireless access, spare;

4 jacks to office (8' run) - computer, printer, spares

2 jacks to kids room - xbox, old pc w/o wireless.

I plan to extend in the years to come, to the second level for wireless and younger childs future pc, to the detached garage for wireless, etc.

I've acquired a switch and patch panel, 250' of cat6, and all the currently necessary extras and tools. I also have a few spare wireless routers - Netgear 6400 AC1750, Netgear WNR 2020, and linksys ea3500

My ISP is AT&T fiber optic, claiming to provide 300Mbps or something (I'll look it up once I find my wife's login), and wired speeds seem to be legit. Trouble is the wifi. Currently only the main computer is wired, and everything else is draining the wireless - AppleTV, 3 phones, xbox,

As of this update, PC client appears to be using Steam Network Sockets, which means your IP is now hidden from other players and you cannot be DDoSed.

So, Proof is incredibly difficult without going very deep into the technical way it was discovered (Binary reversing, looking at the assert strings). However, This update changed Destiny 2 PC to use Steam Network Sockets rather than normal Windows Sockets.

What does that mean? This means that Peers (other players, servers, etc) are no longer addressed by IP Address, but instead a Steam ID. Valve then takes this Steam ID Address, routes packets to the nearest Steam Data Center, then bounces the packets around inside of Steam's data network and exits them closest to the peer. The only IPs you would see are entry points to the Steam network, which masks your IP from your neighbors.

the tl;dr: You can no longer be DDoSed. Your IP is hidden from other players in the game.

You can read more about Steam Network Sockets here: https://github.com/ValveSoftware/GameNetworkingSockets and here: https://partner.steamgames.com/doc/api/ISteamNetworkingSockets

Question About Network Issues In Home

I don't know much about Networking, so here is my situation.

We recently just moved into the suite of my parents house, as we save for a place of our own. Currently there are 3 of us that are heavy gamers. Sometimes 4 when my brother comes over. In total there are about 30 devices in the house that are connected to the internet connection. 2 PC's that are directly connected to the router.. 3 When my laptop is plugged into the router (but my dog ate the CAT cable. -_- ... We don't get very good signal in the basement suite to begin with, but it's ok most of the time. We do have a "booster" but I don't think it works. Needless to say, when someone uses something upstairs, our internet is sooo crappy downstairs. We can't even load facebook on our phones, and Netflix doesn't work etc. It's getting super frustrating not being able to do anything!

Is there anything we can do to fix this issue? Should we get a second wifi router downstairs? Please help! >.<

Thanks

Advice: Push Notifications between devices on different networks

I've been trying to figure out the best way to send push notifications from a server to remote devices when actions occur on the server.

Initially, I began looking into Web Sockets, letting each remote device establish a web socket connection to the server, and maintaining that connection forever, although I believe this will be problematic when trying to scale.

I then came up with another way of doing it, where the clients will each be port forwarded and running their own simple server, and the client will periodically send their current public IP address + port number to the server, which the server can then use in the future to send messages to the client. There is significantly less overhead with this method, although there could be downtime, and there could also be a security issue by exposing the port.

I'm just trying to figure out the best way to efficiently send notifications from a server to clients, where the clients won't be on the same network.

Home network - router, mesh and ethernet advice

Hi,

I am renovating my flat and was planning on using a small Google mesh network as I have had poor wifi coverage in the past due to structural issues. I am also adding wired network ethernet points throughout the house.I have a few Sonos devices and other home automation hubs such as Philips Hue.An electrician suggested switching the position of my router from my living room (next to the TV and in one corner of the flat) to a more discreet central position. I have never had a house wired with ethernet cable before and I have a few beginner questions:

  1. If I have the router where the electrician suggests, away from the TV, can I still plug any device into the ethernet cable in any room - and have the same speed as if it were plugged directly into the router? For example the broadband TV box in the living room connected by this cable, with no delay etc?
  2. When you use a mesh network like Google Wifi, do you generally disable the wifi on your router? - if so there doesnΒ΄t seem much

how important is it for a network engineer to understand the physical layer ?

i'm a computer science student who is considering a career in networking , my university's curriculum for the CS bachelor's degree include quite a bit of networking courses , they are :

  1. data communication and networking with emphases on networking .
  2. wireless networks
  3. multimedia and networks
  4. network programming
  5. computer and network security.

out of these i only took the first one , which provides an introduction to data communication, basically at first explaining the basics ( LAN, WAN , OSI model, TCP/ip model , network layers, what is protocol , etc ).

then after we studied signals and the very basics on how to evaluate the performance of a network , like learning how to calculate bandwidth , bit rate ....etc.

after that we studied switching , we focused on just understanding the importance of switching , circuit - switched networks and packet - switched networks and the difference between them , we didn't study virtual switched networks .

Can't connect to some websites on network?

Hi, recently i noticed i cannot access several websites from any device on my network. For example, going to the steam workshop gives me an "Access Denied" error, going to my.nintendo.com and logging in gives me the chrome "This website is not safe" screen and the page never loads, and the switch can't even connect to the eshop. I'm not sure what's going on or what to do, does anybody know what causes this? I'm on optimum with their basic modem and router using my own netgear router plugged into it by the way.

EDIT: It looks like it's an issue with the SSL certificate on my IP. No clue what that means, but that's what i've been getting.

Network config sanity check

I’ve been living with a router on a stick network configuration for a few years now. It’s been fine. I’ve been thinking of refining it, however, to make it a little more resilient.

Equipment:

  1. Router w six ports (2 Gbps, 4 ports that handle combined 1 Gbps).
  2. Switch (48 ports).
  3. NAS (synology, 4 ports).
  4. UPS monitored by NAS.
  5. Cable modem.
  6. Power mgmt box (blue bolt).

There’s other equipment (wireless APs, security cameras), but the above equipment is the backbone.

NAS runs vpn, log server, and tftp server for network equipment. Also, runs user level apps like backup software and surveillance server.

Plan:

  • blue bolt plugs into UPS. Modem, router switch and NAS plug into blue bolt.
  • both switch and router Ethernet connect to NAS on VLAN 10 (restricted VLAN for administrative work like tftp), different IP addresses for each port.
  • NAS Ethernet connects to switch on VLAN 20 (user vlan).

If power goes off, as long as cable stays up, I can connect over vpn to adminis

Wifi network advice for apartment

Up until now my apartment provided comcast internet as part of living there, which was great. The building was bought by a new company who just told me they won’t do this anymore. I think it is ridiculous that 5-15 families now need to pay Comcast $50 EACH to check their email - most of the people don’t live in this shithole because we are rich.

I’m trying to figure out how hard it would be to get internet, a powerful wifi wireless router, but I would need some kind of account control and it would probably need to all run through some kind of VPN to cover my butt from potential legal liability? I could then ask people to chip in $10 a month so we could all have internet again, rather than collectively hand over a collective $2000 for basic service.

I’m not an IT guy, but I am pretty decent with technology - how hard would this be to set up? How much? Am I missing anything? Equipment recommendations? Any help much appreciated, and you’d be helping us not give money to Comcast as well.

Network config: modem + router + switch (cisco)

Current network is:

Cable modem <=> Router (Cisco 1941/K9) <=> Switch (Cisco C2960S-48FPS-L)

After the IT guy who recommended a bunch of equipment fell off the face of the earth, I decided to setup my home network myself. I'm a former computer security expert (application level) but not IT trained. Network works, but could be better. I set up some VLANs (security cameras, etc.), plus Cisco security zones.

Problems:

  1. My network WAN Connection is slow, definitely slower than it should be.
  2. I’m double NATed: router & modem.

Internal LAN is speedy.

I recall IT consultant said we could plug the modem directly into the switch. I didn’t understand this at the time. I think I understand better now. If I put the modem on its own VLAN and run security protocols between VLANs, then that should be secure, right? I’m confused, however, because I assumed that the router (with its security card) being between the modem and the switch (and therefore my internal LANs) provided

Newb here, first time server and network setup for smb office, wondering best method to replace DC/ADUC.

I am very new to server setup, this is my first attempt and I have had little to no help so any help would be greatly appreciated.

So very small current environment, -one tower server running Windows Small Business Server 2011 -one Netgear 12 port (I think) switch -10 clients LANed in / 5 or 6 wifi

New environment same amount of clients but moving to new physical tower with Windows Server 2016.

My main question right now is, can I setup new server with secondary DC role (adding it to domain while old server is still on domain as well), then eventually remove/demote old server DC role. Would clients still be able to login with existing username and password and have access to new server file share (once file share is also setup).

I don't want to do a migration and potentially lose data when it would be much simpler to more or less setup new server side by side with old server then remove old server from network.

Thoughts, guidance, opinions, questions? Thank you all so much i

While I figured the right Wi-Fi setup would do the trick, since the couple were having their new home renovated anyway, I suggested having the electricians run network cable between the two locations, using the easily available ceiling cavity, and to the intended location of their home entertainment setup as well, while they're at it. Wired is IME always faster, more reliable, cheaper, and easier if you're renovating or building anyway.

Someone Else Controls my Network and I want to Remotely Access my Web Server

Hey all,

I am living on a college campus and I want to host a web server to do cool things with my home electronics when I am away from home. I’ve done this in my previous living space using port forwarding to send stuff to an MQTT server, but now I have no control over my ports as far as I can tell. When I moved here, my housing office gave me a username and password to log into my own little safe space within the network where I can only see my devices. There is an access point in my living room that is just a wifi router connected to the wall.

So that’s my situation and I’m not really sure where to start looking for a new solution. Here are some questions:

  1. Is there any way I can set up a web server accessible without having to go through a port on the secret master router that I don’t control?
