WiFi works, but cannot see my own network SSID

Post by makdev »

Hi, all
Have been wrestling with this for a week and am completely at a loss.
Very, VERY inexperienced in LX.

The problem: WiFi enabled, I see my neighbours' weireless networks, but not my own SSID-s
We've got 2 WiFi networks in the house, none is hidden. I don't see any of the "in-house" networks!

I've seen quite a few threads about Qualcomm Atheros, which I'm running.
Can it be as simple as installing/updating/enabling a driver?
Please help!
Many thanks in advance

You can try to set regdomain for your localization. https://wireless.wiki.kernel.org/en/dev ... Regulatory

You can temporarily set with following command.

Code: Select all

sudo iw reg set YOUR-COUNTRY
Instead of YOUR-COUNTRY, you will write your country abbreviation. For example, you should edit the command for Australia as follows.

Code: Select all

sudo iw reg set AU
If issue solves this way, it can be made permanent.
