Linux mint detects every wi-fi connection except my router

[BananaBreadCrumbs]

Hi, i have been using linux mint for a few months and it's great, only problem is that sometimes the wifi detects EVERY connection near me except my own router and i don't understand why, this is not the first time it happens either, sometimes rebooting linux solves the problem but this time i have rebooted my pc an hundred times and still no lucky, any help is greatly appreciated, thanks!

I have a similar problem. So far, it is connecting now to the router instead of a printer we have on the network. What I did was go to Printers ---> Configure printers and put in a false location and in Access Control "Deny printing for everyone except these users:" and put in a dummy user name.

With network you could probably achieve the same thing by going to Wi-Fi Security for any of the networks trying to connect you and putting in a fake password. This would skip to the next and eventually come back to the network you actually do want to connect to.

Can you change the channel your router is on to 1-11 on 2.4GHz as Broadcom devices are notorious on Linux for not allowing 2.4GHz above channel 11

heres the thing Jeremy, i don't know how to change channels on my router :cryingemoji:

You could try turning it off and back on, that might cause it to change channel. You chould be able to access the router web controls by using 192.168.0.1 or 192.168.1.1 in a web browser, the IP should be listed in results from terminal for

Code: Select all

ip route

My router IP shows in the first line of results default via 192.168.1.1 dev wlan0 proto dhcp metric 600
Since you seem to be connected using ethernet you will see something other than wlan0 on that line
