I'm in a brand-new construction home, with Xfinity Internet/TV/phone.
Several times/day, the wifi signal from the gateway simply goes away...TV still works, computers cabled into the gateway still work, but my cellphone can't see the SSID and all the wifi-connected devices lose connection (including my xPods).
Within about 5 minutes, my cellphone can see the SSID again and starts trying to connect. There's usually an authentication error, then a "we'll reconnect when the signal's better", then it connects. Within 10 or 15 minutes, the xPods are back and everything is happy.
I've been on the phone with tech support multiple times. One tried to tell me it was caused by 'older' devices on the wi-fi, and suggested that maybe I should buy my own gateway (!!). A tech that visited said I should return the gateway for a new one. I've done the power off/on, I've done the factory reset, they've sent a reset signal...nothing seems to help. The #1 critical piece of information is that I don't lose internet...the two computers that are cabled into the gateway never lose connectivity. The #2 critical piece of information is that the SSID beacon goes away...my cellphone can't find my wifi network for the few minutes it is down.
So, it seems that the gateway actually stops broadcasting a wifi signal. This is driving me crazy...and I'm fed up with calling support (6 or 7 times now) and getting a different story every time. Anyone else out there having a problem like this?
Looking into things, I may decide to get my own modem. My wife still uses a land line, so looking at the NetGear CM1150V, then adding an Orbi wifi router and a satellite or two. Expensive, but I'm tearing out what little hair I have left over this wifi issue.
If you are using a Comcast device, I would call Comcast support and have them address the issue. I prefer and have my own modem and separate router. Over time it is cheaper and having separate devices, makes debugging issues easier. When dropping a connection with separate devices, you bypass the router by connecting direct to the modem and see if you still have an issue. If so, it is the modem or the ISP (Comcast). Otherwise it is in the router, so you debug it.
Some tips for improving WiFi performance;
There are other options. Google for WiFi repeaters / range extenders, WiFi mesh systems / pods.
