I recently started running into a problem with the new upgraded Comcast/Xfinity Wireless Gateway that Comcast is upgrading their customers with. I had a client that I installed an Almond WiFi Extender in their home 6 months ago and it has been working just fine. Suddenly it stopped working, in that it connects to the network but without an internet connection. I assumed the Extender had failed so I installed a brand new one and same thing. It connects to the wireless network but no Internet.
I took the Almond units (both new and old) back to my place where I have both Comcast Internet and FIOS and started experimenting. I had the same issue. I could connect just fine to the Comcast wireless but not Internet. When I connected the same extenders to my Verizon Fios network, they worked just fine. Just to double check, I went out and purchased a new Amped Touch screen Wifi Extender and tried that and I get the same problem.
I researched on line and some others are having the same issue and some claim that Comcast has told them that the Comcast Gateway DOES NOT work with Extenders?????
The thing that is puzzling me is that the Extender that I installed 6 months ago was working with the Comcast Gateway just fine and suddenly stopped working so all I can think of is that Comcast may have pushed out some form of update to the Gateway?
