BGW210-700 won't mesh 2.4mhz and 5mhz devices
First question, is why does AT&T not have a technical support number listed anywhere on their website or within the account? Comcast had that ability, even though their tech support was generally pretty bad. Just saying.
Real question. I just switched to AT&T Fiber from Comcast and AT&T provided me a BGW210-700 modem/router. It has the capability to run devices at either 2.4 or 5mhz. I have a Sonos system and an HP printer that all run at 2.4mhz, then I have laptops and gaming systems that run at 5mhz. The credentials for both the 2.4mhz and 5mhz bands are the exact same, but when running this way, my computers and cell phones (5mhz) can't see 2.5mhz devices (printer and Sonos). When I went into the system and disabled the 5mhz option, all devices were forced to 2.4mhz and everything has been working perfectly as normal.
I'm sure folks will agree, I shouldn't have to do that for functionality to be achieved. The modem/router describes itself as being able to internally manage those devices' interconnectivity, but in my case, it's not. I know I could run all on 2.4mhz and not see a huge affect on speed, but I wanted to solve this if it was possible. I've searched online for this and every time I find a forum post that's similar to mine, it's unanswered. Any help would be greatly appreciated.
