I have set up port forwarding for port 443 from Xfinity Gateway to my home server. It works fine if the connecting device is not in the home network, but it fails to connect if the device is in my home Xfinity network. I have reached out to Xfinity technical support for this. They have a hard time u

We've been experiencing extremely high latency for the last one week to ten days. Yesterday was the worst. I went to the local Xfinity store and they opened a ticket in their system. An hour later I received a recorded message that the issue I had reported had been fixed. I rechecked the latency an

Anyone figure this out yet? I went to Xfinity yesterday and they had me buy a new SIM card. That did not work. Then they told me I was still connected with T-Mobile which is impossible but I went there as well and there's nothing on there and they could do obviously. This is really getting annoying

Hi - I have been receiving this message every 3 days or so via email. I can see the device logged in, but cannot determine how to block this MAC address from logging in?  The MAC is the only constant, besides it's a generic brand of computer running Windows 10.  I am able to pause the dev

We just moved to Harpers Ferry, WV. We had Xfinity home internet installed on Friday, using the comcast-provided gateway. There seems to be some problem with how our wifi network is configured though, because every single device we have connected to wifi bounces back and forth between seeing us in H

Issue: (tl/dr Cable Modem Overheating) I received this thing maybe a month ago after signing up with a gigabit internet plan. Over the last two days my internet has begun to intermittently drop without warning and spontaneously. Troubleshooting: I have observed this over the last few da

I have a Motorola MB8611 and have had no issues the first 18 months. The last month have been getting multiple dropouts a day.  Looking at the cable modem during a dropout typically the downstream connection is flashing.  Below are all the details I have, but the OFDM PLC / 32nd channel s

Has anyone had all their stations and channel lineup changed? This morning my normal abc local news is now a Spanish yoga channel. The local stations are all stations not in my area. It’s like I somehow have someone else’s lineup.

Just a WARNING that all Pac-12 Network channels will be shutting down around June 28. COMCAST HAS NO CONTROL OVER THIS!! This is a decision by the Pac-12 due to the fact that the Pac-12 itself has more or less disintegrated into only 2 schools. https://cordcuttersnews.com/the-pac-12-network-will-shu

80ms ping times during evening/night hours. The issue is affecting a large number of customers. ‎CR088164313: High ping time on Seattle area node 24.124.128.162 during evening/night hours. | Xfinity Community Forum https://www.reddit.com/r/Comcast_Xfinity/comments/1365tgz/still_having_latency_i

I have both AEs connected (at opposite ends of the house) to the router via Ethernet. All have the same Network name and password. The AE are currently set as "Create a wireless network", shouldn't they be "Extend a wireless network". I noticed they all have different IP address. Thought they need t

Cannot delete CBN and Univision from my favorites. When I unstar them, it automatically restarts it within seconds. Neither are channels I would ever watch! Clearly Comast is manipulating my favorites to keep them on. As I’m not Spanish speaking there is no way I would ever watch Univision. I also w

I have no idea what this means and it says it will almost 1 am before resolving is it something on my end I can do

App stalls at entering of new network name and password. Just says there was a problem. Please try again. Keeps looping same error message.

I recently switched to Xfinity Mobile, but I’m not having the best experience. The tower reception is spotty, and the internet speed is slow. Before you make a switch, I suggest you check out the coverage in your area. It might not be worth it for you.

Hi, I have successfully opened some ports pointing to my server. I have a custom DNS entry to point to my IP, let's say server.home.com. When I access https://server.home.com from outside my home, everything works fine. When I access https://server.home.com from inside my home, request fails.

I see many (closed) posts to this, but I can't find a resolution. I have Xfinity's xFi Gateway, 2Gbps internet service and 4 xFi Pods deployed, all online. I get this error with my iPhone 15 Pro, but it's erratic. I just replaced my iPad with a new one, and it also is getting this error. My wife has
