I have a CAX30 modem with the latest firmware. If I run a speedtest from the CAX30...it's 300Mbps on a good day. I ran a cable connection diagnostic from the modem and this is what I got. Does this look ok? I do see channels 23 and 24 with the lower SNR and power difference. Could this be causing me

The maintenance was not further explained, and I can't get any details by calling Comcast's horrendous support number. The outage occurred overnight and lasted about eight hours. It was planned, but not communicated to us until after we called to find out what happened. Now my IP address is geolocat

Speed has been less than 50% of high speed plan for several days. I spent a lot of time with the "Xfinity Assistant" running tests. They say speed through their network to our modem is fine, but the SpeedTest while standing right next to the modem sometimes drops to only 10% of plan. That causes int

I have three and a half minute video of trying to log into Xfinity. It takes you through two factors authentication and then sits a spins for a full 40 seconds then says it has problem - "try again". After hitting that twice it logs you out and you do two factor authentication, again. This went on f

Two days ago 1 Gig up/down symmetrical and all other symmetrical plans populated the internet plans page for my address Signed up for 1 Gig up/down today. Was given an XB8 at xfinity store. As I understand it, XB10 modem is required for symmetrical up/down plans Currently seeing 1000/100 mbps speedt

I’ve recently upgraded my internet package to 400mbps, however, I can't enjoy it while gaming. Every other device (phone/tablet/laptop) I've done speed tests on shows down speeds of ~400mbps EXCEPT my Series X. If I do the Xbox system speed test, or even use speedtest on the Edge browser, I get no m

I have noticed that many posters in this forum, no matter what their internet speed plan through Xfinity is, are experiencing half of what they are paying for. I am no exception. I am always at 540 mb/s or so over ethernet, despite paying for 1000 mb/s for the past 24 months. I tested this on speedt

Hi, I have a gigabit Xfinity internet plan and use my own modem, a NETGEAR Nighthawk CM2050V. When my Windows laptop is connected directly to the modem by Ethernet, Windows shows a 1000/1000 Mbps link speed. However, Ookla Speedtest is showing only about 20-40 Mbps download and around 40 Mbps upload

Hi, I've been an Xfinity customer for a long time. I'm having issues with low latency gaming and was wondering if it's an Xfinity routing issue or maybe an issue with the Xfi gateway router modem combo. I'm familiar with the bridge mode but was interested if it was a routing problem before I purchas

I am requesting an in-home technician visit for intermittent internet degradation and possible DOCSIS/coax signal impairment. I am on the 1.2 Gbps plan. My Xfinity gateway is in bridge mode and hard-wired to an Eero 6+ primary node. I am testing over time and consistently when about six feet from th

I have an Internet only plan with Xfinity. I originally had 300 mbps plan but over the past 2 years was upgraded to 600 mbps (paid for this) then updated to 800 mbps and then 900 mbps for free. When I was updated to 600 mbps and ran SpeedTest I would get 600+ mbps all the time at the Ethernet ports.

Over the last couple of months I have noticed my internet has very noticeable spikes in latency, even though my router is getting 100% of my gigabit plan speed. It's noticeable the most when playing any online game or video calling. I ran a Speedtest today and the download and upload speeds are norm
