Sorry, I don't see an obvious place for a D9 thread.

I have picked up the below.

running win7 64bit

Archer D9 modem/router

Archer T9E wireless adapter
Driver Version: 6.30.223.228


2.4GHz works no problem. I have a solid connection even down the street. through multiple walls. It just works. great.

The 5.0GHz signal is a different story. Its weird, The initial quick setup of the D9 I was able to see the signal and connect (although it was very very weak)...soon after it dropped and I couldn't find it again. So I reset the PC and reset the router. Pops back up connects again only for it to drop and disappear again.

I am fairly certain its the D9 causing issues. I only suggest this as it seems the signal appears after a reset of the modem only for it to drop and disappear again. I can also see a neighbours 5G connection coming in and out

I have also updated the firmware and drivers on both.

Any ideas?



edit:

I downloaded WifiInfoView and tested the channel signal quality on each of the 5GHz channels.

When I manually select a channel;
I can see all the lower channels. 36, 40, 44, 48.
But, I can't see any of these when selected. 149,153,157, 161

Should I not expect my wireless adapter to be able to see all these channels?

Also, turns out the other 5GHz signal was coming from my wireless headset. I have turned it off, but makes no difference.
