If your router allows you to create a virtual access point you can do that for just the Quest. You can set the VAP to act as a standalone VLAN or still be on the same Lan as all of your other devices. This can resolve other issues as well, but they have their own threads.
Thanks for sharing! I use Unifi AC Dual Band AP's at home and it combines the 2.4 and 5 Ghz... absolutely no issues. This must be an isolated Comcast hardware/wifi issue. Be sure your modem/router FW is up to date.
I have this problem on Netgear Orbi, and have had the problem for months before it got bad enough for me to go online to look for a resolution. I don't think I have the ability to turn off the 2.4G band, I've looked everywhere in the configuration, including advanced wireless settings.. it seems they try to simplify things a bit too much. My orbi system has two satellites (repeaters), and the relevant config is currently: Hardware version: RBR20 Firmware version: V126.96.36.199 GUI Language Version: V188.8.131.520 --Wireless settings-- Region: Canada 2.4G Channel: Auto (8) 5G Mode: Up to 400 Mbps 5G Channel: 36+40+44+48(P) 5G Mode: Up to 866.7 Mbps 2.4ghz b/g/n: Enable 20/40 Mhz Coexistence Enable WMM Preamble mode auto, transmit power control 100%, 5ghz a/n/ac: Enable WMM Preamble mode: auto, transmit power control: 100% Backhaul topology: Enable Daisy-Chain Topology
NOT checkmarked: [ ] Enable Implicit Beamforming [ ] Enable MU-MIMO [ ] Enable Fast Roaming
I have the guest network turned off, my first attempt after looking for firmware updates is going to be to try turning it on since it uses a different SSID, in case that SSID is restricted to only one of the bands.
The newest FIOS router uses SON and only has one name available so you cannot split the network names. Never had this issue until I got this new router (my quantum died). Now every time I put my headset on I have to reconnect tot the Wifi.
Thanks for sharing this with us. It's not only with you, many of us face the same. Few time back, I encounter this problem on my Linksys, and I was looking solution for this. Luckily I got to know about the website linqssys.com, they helped me to get rid of it.
