My Ring Chime was refusing to connect to WiFi, but pretty every other device on the network was fine.
It turned out my modem was both ARP spoofing as well as changing it's MAC address, and escaped the MAC-based vlan I had originally gated it behind.
The full story as well as the tools I used to find it (Wireshark did most of the work) is here if you are interested it read more:

Back in the day, I supported a real time energy trading app that used modems to connect the trader PC to our app. Trader called screaming because the app wouldn't connect and he was losing thousands of dollars every minute. We go through the first steps of troubleshooting and discover that the modem is not getting a dial tone. I ask if he can call me from the line that the modem uses, so we can try to isolate the issue to the modem, at which point he screams that is not possible because a bleepbleep construction crew cut the bleepbleep phone cables outside the building, "so how the bleep can I call you on that line?" I then ask how he is calling me to report the issue and he screams he is calling on his bleepbleep cell phone because the bleepbleep office phones aren't working. And then asks when I can fix the bleepbleep app...
This friend of my moms called my mom and eventually found my number . Hughsnet had sent her a new satellite modem for her dish and she had zero luck setting it up (she couldn't even figure out to plug in the power cable kind of thing). So I drive up into the mountains.. serious boonies. I get it set up after some small issues.. (gave her a new ethernet cable) and fixed her sound problems on her pc .. she was a friend so I'm like i'll only charge an hour but be glad to trade for some elk/deer/lamb etc.
She gave me 3 packages of elk backstrap.. 2 big packages of stew meat and 2 roasts ..
I cooked up one of those backstraps on my grill... so good .. must have been a young elk
so worth the freaking mountain drive and she was happy not to pay $$
life is good sometimes
edit: there is a giant package of stew meat.. gonna get a bottle of red wine and make an elk stew. brown it up with onions, celery, red peppers then add about a bottle of red wine and simmer that shit down.. maybe a bay leaf, black pepper... some chili flakes.. a bunch of mushrooms. Maybe some garam masala in there.. should be grubbing
I've heard it 2 different ways:
The X55 has no CA capability over 5g
The X55 can only do TDD+TDD or FDD+FDD or mmwave+mmwave (Ex: n41 +n71 impossible, but n71+n66 possible)
I currently have a 400 Mbps Comcast Xfinity plan and I have Arris SB6183 modem. The modem supposedly does not support my current speeds. I am looking for a new modem with future in mind, where I might opt for the Xfinity's gigabit plan.
I am debating a few options:
I plan to just hook it up to router and use wifi and do not plan to use wired connection. Please suggest me which one should I get. I am currently thinking of Netgear CM1100 as I am able to get it from Costco, which is some added peace of mind. However, I want to make a well informed decision.
I'm looking into getting a Nest WiFi setup but I'm currently with Plusnet and their bundled router doesn't support bridge mode. So I'm looking to buy a separate modem to go with the Nest. I'm not sure if I'm using the wrong search terms or what, but all I come across are modem/router combos.
Can anyone point me to a good buyer's guide for a modem-only device to use in my case? Or do you have any personal recommendations?
Thanks in advance!
I took off the case and found these directional antennas. They are held in place with tabs.
(For those hesitant to take it apart, it looks like it was built to be taken apart and goes together very well. No seals or traps or anything difficult. Well designed.)
TLDR: Tech support is adamant that the connection is fine on their side and wants me to order a new modem, but I experience the same “no internet” problem with another CenturyLink modem. How can I get them to send technician?
Our internet went out yesterday. I spent the night with tech support rebooting the modem to factory settings, but still no resolution. Tech support says there isn’t a problem with the line to the house because the WAN/LAN light is green. They say the problem is with the modem and want me to order a replacement.
After I finished tech support call, I found the previous CenturyLink modem when we used to have their TV service. I rebooted it to factory settings and was able to login with my current PPP login, but have the same “no internet” connection problem with this other modem as well. Therefore I doubt the problem is with the modem.
I checked that both modems have the latest firmware per CenturyLink’s website. Both modems have steady green WAN/LAN lights, have PPP login, and the configuration pages say the WAN is connected. But both say there is no internet connection and the internet light alternates green/red. Any suggestions if this really is a modem problem or is there a connection issue on CenturyLink’s side.
I can’t wait days for a new modem and will probably try to self install Comcast service if CenturyLink can’t resolve the issue.
Recently switched to AT&T due to lagging up speeds with an otherwise much better (in terms of customer support) provider. 2 person household, medium sized apartment, we both WFH. Though we are online at the same time all the time, we are rarely in meetings at the same time. My wife is a little further away from the router with another wall in between her and the router. Both of us are still occasionally seeing some freezing and skipping on Zoom calls. Though she's seeing it worse than I am. It's pretty smooth for me most of the time.
I had her do a speed test in the room with the door closed. She was still getting about 100 up & down at the lowest. Sure, that's not gigabit internet or anything, but it should be plenty to work with for Zoom meetings. We were freezing a lot more and getting dropped prior, but we were still able to at least be on meetings when we essentially had DSL speeds (~24 down / 1.8 up).
I told her to look into WiFi boosters and we could test one out. But with 100 up & down, seems kinda like it's something else. That should be plenty of bandwidth for one at at time Zoom calls.
I upgraded to 940mbps from 100mbps. I have a c1100z and I was getting 92 down and 48 up before the upgrade. Now I’m getting 92 down and 85up.
Do I need to get the c3000z modem to see the full bandwidth increase?
EDIT: Solved by plugging the centurylink router directly to the ont once.
My speeds afterwards: ONT -> CenturyLink Router -> Google wifi (DHCP), I get 700/800. ONT -> CenturyLink Router (Transparent Bridge) -> Google wifi (PPPoE), I get 500/200.
If I plug the cable directly from ONT to Google a wifi in PPPoE mode, it doesn’t connect to the internet.
Working from home where my work computer is located in my office. The ethernet cable of the computer is connected directly to the ethernet port in the wall. Worked like a charm.
However, I have received the new Fibre+ Gateway modem which I have set up and replaced the older modem. Suddenly my work network is unable to connect. Only solution is if I bring my work computer upstairs where the modem is and have it directly connected to the modem.
Anyone know how I can resolve this so I can just connect my work ethernet cable directly back to the wall?
Our DSL Modem/Router is about 10-years old but is running a current-version of dd-write. We do not use wifi with it as we have a separate house-network for wifi.
We live out in the country and only one ISP with 6MBS-DSL plan. As the load increases on that DSL, our speeds get slower and slower. Right now it is good at 6.2MBS, but some evenings it is down to 1.2MBS. They cover their asses by stating "speeds are not guaranteed."
I am just wondering if there is any sense in buying a new modem/router to squeeze a little more DSL performance.
Other than wifi, have there been any significant changes in how the DSL modem/routers work?
I'm upgrading from AT&T to Spectrum; my current router from AT&T has a WAN ethernet cable and 4 Ethernet ports. No coaxial cable. Most modems I see only have a COAX connection. Can I get away with just a router? Thanks.
I have cat6 in walls (bought new flat 4 years ago) and my pc is wired to router. Tp link archer c7 sucks ass as I have 600mbit connection and it does 70Mb/s only for few hours and then it chokes to 50-60. the cpu is too weak I guess...
So I need a better router... And that made me think about this whole stuff.
I did had fibre cables ran to my flat but never used and broken by the renovation guys... As I found out years later... My ISP runs that 1 thick Wire, splits it for tv/net and their small modem just outs 1 rj45 which I run to my wall and to the archer c7. So there is not even an option to run cable to multiple outlets without somehow putting a switch in there.
But that aside - What if my ISP will soon come out with Fibre offer? let's say they will fix my broken ass fibre cables somehow... What's even the point of doing that? If I will want my pc wired, it will still have to use rj45 connection. So fibre modem(or how it's called) will output rj45 to my wall, then to my router and to my pc.
So why do we need fiber at all?
edit: OMG so many answers. Thanks a lot everyone! So there are very CLEAR benefits for ISP to run Fiber cable up to my door or at least to the apartment building even when user runs on copper inside his home(which is 99% likely nowadays). That will not affect speeds negatively. I also learned that I need to get some rj45 tester to see if my cables are all good. For now, I fiddled with some settings on my c7 and will test for few days to see if it will start slowing again. I will get ddwrt on it if it's still crap. I think the cpu is just too slow so maybe ddwrt is ligher.
What I want to do:
My modem supports port aggregation. I have a managed switch with 128gb/s backplane. I want to leverage the two 10gb/s connections I have from my switch to my firewall, one for LAN traffic, one for WAN. I want to route 2 of the RJ45 (23&24) ports - will be aggregated and connected to modem - to one of the SFP+ ports (27) with my WAN traffic.
What I've tried:
In both cases the firewall doesn't pickup an IP from the modem.
What I have gotten to work is: Creating an adhoc network from my laptop, and connected it to port 23 (with aggregation turned off). The firewall then sees the IP of the adhoc network, and grabs an IP from the adhoc network's DHCP server. This is obviously useless, but I used it to test my VLAN configuration. This worked in the first configuration, where everything was untagged.
Any suggestions on how to get this to work?
I’m mainly looking for input from people who upgraded to an iPhone 12 or 12 Pro from an iPhone with an intel modem (11 series). Aside from 5G which is an obvious difference, have you noticed a significant change in terms of better speed on LTE, or more importantly, getting reception in places where your intel phone previously struggled to get any bars?
I’m on the iUP program and trying to figure out whether it’s worth upgrading this year; the modem thing is kind of my make-or-break question. My 11 Pro Max has a whole lot of areas where I get basically nothing.
