Change these (for both bands - 2.4Ghz and 5 GHz) from Auto to:

Then test the C7 5Ghz band.

Sorry to jump in, is the Archer C7 V4 an EU version or US version? If it is an EU version, it only supports band 1 (36~48) for the 5GHz, which is designed to comply with that of CE regulation. That means if your phones don't support these channels, then they cannot work with the router.

5GHz band 1 channel: 36~48
5GHz band 4 channel: 149~165

 

Do you remember what is the previous firmware version on the C7, and which channel did you choose before the firmware update?

@Kevin_Z thanks for replying.. yes router is su version.. and it's back side states that to EU.

 

I updated the firmware to US & EU both, but it didn't work out. Channel range was say 36,40,44,48.

 

and I think before updating , when it was working.. it was on a old version where "operation mode" option  was not available.

Hi, if that is the case, then it can only support channels 36-38.
