My laptop works fine with other wifi in other places (even after I installed Ubuntu, 22.04); But somehow it lost vision of my Home Router signal! I run both Windows 10 and Ubuntu on it and both OS don't see it. Laptop: Dell M6700 Adapter: Broadcom (2.4 Ghz)

Wifi Router: Asus RT-AC1200G+

I'm not Pro in Linux.

Please, where do I need to search for a problem cause?

I repeat: adapter works fine with other wifi signals, I can connect to them. My router works fine too, my phones and Tablets are connected no problems at all!

I don't understand how it can't see radio from router at all! Or how do I check if adapter is seeing the signal?! Any special comands for this in terminal?

If need more detailed info let me know and how do I provide it?

Thank you!

  • Is your router broadcasting its ESSID? If not, you wont see it in the scan results, but you can still connect to "hidden network".

  • Check that your router and laptop are using the same band for radio (G vs. N ). Routers may do both, or just select one. Any other complications like range extenders?

  • Look at the network logs with the terminal command: sudo journalctl -b 0 -u NetworkManager. Also do: service NetworkManager status and service --status-all.
