I purchased an Arris sb8200 and an Asus ax3000(rt-ax58u). I activated the modem and I could get internet if I hook up through through ethernet. When I plug in my router through internet it does not establish a connection. In the admin panel of the Asus router it says "Your ISP DHCP does not function

My ring video doorbell pro has been assigned 2.4ghz and it is very slow at processing video. I know how to access the router and have changed settings to 5ghz in past years, but can't find the info to follow to do this today.  Has xfinity stopped allowing customers to do this?  If not, co

RNG110 cable box no longer working properly. The green power light is on but the yellow data light continues to flash and there is an error message on the TV screen "Reference code SOaOO".

​​Hi, I am hoping someone can help me with my issue of having T3 timeouts which happens a few times a day. It is causing my internet to go down for about 1-2 minutes when it happens. I just moved into this house 3 weeks ago and I have been having this problem every since I got here. There was alread

Nobsound/Douk Audio The code for this brand is not listed by Xfinity. Does anyone know if the code is shared with another manufacturer that I could try?

My landline phone worked fine until yesterday and now has no dial tone. Cannot make or receive calls now. Phone is wired to Xfinity modem. The landline handsets are charged and being on or off the hook doesn’t make a difference. Modem has been restarted multiple times both through the Xfinity app an

I have only just noticed how HOT my XG1 v4 box is getting. Even the cable connection is almost a burner. The bottom of the unit is the hottest. I have moved it so it is on top of the tv unit but it is still very Hot. I have had no issues but just how hot is it supposed to get.

If I buy Max and Showtime outside of Xfinity, once I log in to both using the Xfinity app for each will I get the channels on the cable box so I can watch online or thru cable?

Subject says it. I'll probably have like 1-2 weeks of overlap, but want to retain the wifi at both houses for the security cameras and to be able to work from either house while overseeing things being moved. Probably means I need two accounts, or no?

There are three types of mobile messaging:   1.) SMS/MMS -These use your mobile carrier's cellular network and are hosted on their servers to route them and store them when you are offline. They do not use WiFi. These work globally across all carriers. Depending on your cellular carrier and your cel

Can you let me know whether I can fix an internet connectivity problem myself, or if I need service by Comcast (which might not be in the cards due to COVID-19)?   Symptom is that once or twice a day I lose internet connectivity. I can fix it by rebooting the device (Netgear Gateway C3700v2), or oft

Hi there, When I signed up for the Xfinity internet service, there is a promotion for $100 prepaid card. However, I checked the status in Reward center and the status was Returned. I noticed the address is correct but without my apartment number. Is there a way to change it? I tried to call

I've encountered an issue with the last two Xfinity modems I've had. The external IP addresses assigned to these new modems are based out of Rockford, Illinois, even though I live in Downers Grove. Specifically, the IPv6 address locates me in Oak Park, but the IPv4 address (which most streaming serv

Our business phone has been spoofed and people are calling us saying they received a call from our number when we didn't make the calls. Spent almost 2 hours on the phone with Support and I was transferred 4 times. No one really understood the problem. Xfinity support is horrible, you can barely he

Does Comcast have a channel which can display multiple channels at one time (like a quad chart - one selected for audio)? If not when do they expect to provide this simple and popular feature?   Cox, Charter, and AT&T had this but I have not seen it with Comcast. I can't even PIP because the Comcast

I want to change my bill due date to 4/14/23

I can't connect my cellphone to my Xfinity router anymore. The cellphone finds the router, reports the strongest connection.  When I ask to connect the progress bar moves but no connection ever happens.  The router's administrative screen lists it as a connected device but offline. 

(2nd attempt writing as a page error deleted the first post) I've been having for the past month+ a 5-10 second drop in all Internet traffic every 30 minutes or so and it's super frustrating. Especially when it comes to live video streaming and online gaming. I've traced the problem to the DHCP I
