Archer C6U EU v1 not showing 5G anymore

2021-11-20 09:09:14

Model: Archer C6U

Hardware Version: V1

Firmware Version: 1.0.4 Build 20201230 rel.53346

Hello,

I use this Arched C6U for a year. It was ok, both 2.4 and 5Ghz was working until few days ago. I did a reset, factory reset, reinstalled latest firmware (Archer C6U(EU)_V1_201230) and still can't find no 5G.

In wireless settings for 5G I only have 802.11n only mode, channel 36 to 48 and channel width 20-40 and 80mhz is disabled.

Tried with smart connect too, nothing.

Any help please?

Thanks,

Adrian

Hello Adrian, try to install and run a Wi-Fi analyzer on a computer or phone to check if the 5G signal of the router is still broadcasting correctly. If yes, confirm again what is channel it is working on, ensure your phone does support that channel as well.

You can also try disabling Smart Connect and setting a static channel for the 5G network, such as channel 36/40/44/48, then reboot the router and reconnect to the network.
