Home WiFi Range Has Reduced

I am using Xfinity home WiFi and their supplied Arris TG1682G router. I have not had any previous issues with my WiFi signal or download speeds.


Over the past week, the range of our WiFi within our home has dramatically reduced. Whereas we used to have good WiFi signal throughout our apartment, the WiFi range has reduced such that my work laptop no longer connects to the internet in my home office (two rooms over from the router). I have been able to work from that room for months with no issues up until now, but have now had to start working in the same room as the router to get anything done.


I should note that, when in range of the router, we still get good download speeds. We have also already tried restarting the router.

If anyone else has experienced this issue and may know why our WiFi signal is no longer extending as far in our home, please let us know.

Apartment life?


One of your neighbors could have bought a shiny new gateway and it's on the same WiFi channel and stomping on your signal.  They are probably having the same problem.....


Looked at your manual.  Looks like a TG1682G doesn't have much for options, including setting your WiFi channel, but perhaps the firmware has been updated since then and there are some options now.


If you've got a linux/debian box, or even use a live CD, the "iwlist" utility can show you every WiFi source around you, and what channel they are on.  As root:

# iwlist wlan0 scan    /*wlan0 is the wifi device*/


You can download Acrylic Wi-Fi Home on Windows.  The free version will show you all the WiFi sources too.  See if there's one on the same channel with a really strong signal.


With your telephony device/gateway, there's not much you can do about it though if you can't change anything.  Move the device to another room perhaps.....even across the room......


12 feet can make a difference believe it or not, especially if the offending device is directly on the wall 8 inches from where your device is.

Some tips for improving WiFi performance;





There are other options. Google for WiFi repeaters / range extenders, WiFi mesh systems / pods, powerline ethernet adapters, MoCA adapters. Good luck !
