ATT Cisco Wireless AP and 802.11 AC Routers
Does anyone have a setup where you are using your own dual band 802.11 AC router and also have the ATT Cisco Wireless Access Point for the the Uverse wireless receivers? If yes, have you experienced any issues with the 5Ghz Wifi signal from the router?
I am having some issues with 5 Ghz signal only (2.4 Ghz band is working fine).
My Asus RT-AC66U is really close to the Cisco AP. I can't really do anything about that since they both have to be plugged into the ATT Gateway.
I am not 100% sure but maybe the AP is causing interference and that's why the WiFi signal on 5 Ghz is not good? The AP and my router settings for the 5 Ghz band are as follows. Any ideas?
ATT Cisco AP:
Control Channel: 157
Extension Channel: Lower
Bandwidth: 40 Mhz
My Router:
Control Channel: Auto
Extension Channel: Auto
Bandwidth: 80 Mhz

The two 5 GHz access points (and the RG, if Wi-Fi active) should be placed as far apart as you can manage. I'd say at least 5 feet. You can buy longer Ethernet cords, but I know that may not be the only issue.

Thanks for the quick response. I moved them as far apart as I can. Not quite 5 feet though. Long ethernet cable is not an issue. I have all devices plugged into a UPS so to space them any further I will have to get extension cords...
I also changed the ATT AP channel width from 40 Mhz to 20 Mhz and set the channel to 36 instead of 157. Wireless TV boxes still work fine. I am going to test WiFi on 5 Ghz band later but wondering if I am the only one with this type of setup and issue (ATT Wireless AP and your own router both using 5 Ghz)

Have you tried different channels on your router?

Yeah, I tried different channels. I don't think its interference or channel issue anymore. I moved the ATT wireless AP to CH 36 and my router is on CH 149. I think its just an issue with 5 Ghz overall - the higher frequency just can't travel as far as 2.4 Ghz especially through walls.
Oh well. I ordered some 9 dbi antennas to replace the stock 3.5 dbi ones.
If that doesnt do anything I guess I am just going to stick with 2.4 Ghz as I get an excellent signal with that. Not sure 5 Ghz is all that unless you're right next to the router or have a bunch of repeaters.
