New router (Archer AX-11000). 5G-1 issue
So I just bought the TP-Link Archer AX11000 router today. Got everything set up but my phone (and so far my Nintendo Switch too) cant see 5G-1.
And if it does see it, it wont connect, give me the error it cant authenticate. Then when I refresh the Wifi tab, 5G-1 disappears.
No issues with either phone or Switch connecting to 5G-2 though.
Did a firmware update (now 1.2.3 Build 20210719 rel. 14861) but that didnt help.
Never had issues with my old dual band and this is my first tri-band router.
Any ideas?
Update: Adjusted the "Channel Width" and "Channel" via web browser, no fix. 5G-1 always shows up now though (but it says Internet is not available). When I do try to connect I get a "cannot connect to network".
Power cycled the router, no fix. Renamed the network and changed the password, no fix. Turned off and on 5G-1 (via app), no fix.
Update 2: Returned the router and got a brand new one. Exact same issue.
Talked with TP-Link agent. Tried a few things, even tried to set 5G-1 to open/none and it still can't connect. Told them this is my second router. They said both might have been defective. Getting it RMA'd, the replacement should work...we'll see.
