ASUS PCE cant detect 5ghz network

  • 772

I have a wifi card with support for 5Ghz. The card is the ASUS PCE AC56.

I have installed the drivers for my WiFi card from the "Additions drivers" tab in "Software & Updates", using the "Broadcom 802.11 Linux STA Wireless driver".

I have set my router to give different SSIDs to the networks on 2.4Ghz and 5Ghzs.

When I go to my Wifi Settings and I list the visible networks, only the one on 2.4Ghz appear, but not the one with 5Ghz.

What would I have to do, to be able to find the 5Ghz network?

networking drivers network-manager broadcom asus

    Sounds the same as this problem: Wireless lost ability to use 5GHz (PCE-AC68)

    The answer there says:

    I had the same problem as you, and I just found the problem. The 5Ghz network was set to choose automatically the channel, one day it changed to a channel with an high number and my card wasn't able to find the network anymore.

    So just check in your router if the network has an high number channel and change it back to a lower one (now I'm with channel 40 and it's working fine) and check if you can now find again the network.

    I've also open a bug report in the bcmwl package page, if this is the problem click on the "This bug affect you" button in this page

    I hope I have helped you.
