Cant connect via Wi-Fi

Post by kosmai »

Hello,
I am a new user of the linux os. I installed linux mint 19 MATE yesterday on my new laptop making a new partition for it. Problem is, without an externat wifi USB like the ones netgear sells, i have no wifi. However I was able to establish a connection using ethernet. To be more specific: On the taskbar, on its right side, i see rectangle with a small "x" on its down-right corner. When I click on it there are no wifi options shown, as I have seen on videos and such. Any ideas on how to fix this? Here are some info:

Ok, we have some news here. I did what the post you told me to go to suggested and I do indeed have a "wireless" option now. However it says "unavailable" and no networks are scanned. I went ahead and created a connection using the SSID and WPA2 key password. The connection was successful but really unstable, in fact so unstable I was rarely able to log in the forums. Being frustrated by this and many other minor issues I decided to switch to an older version of mint: LInux Mint 18.3 CInnamon, and I really like it better. Thing is that the wifi problem persisted in this version too, so i repeated all those steps (think I also had to install git, no problem there). So I am in the same spot now. Having a "wireless" option but it says "unavailable" showing 0 scanned networks around me, whereas there are many. Any more suggestions? Thanks for any advice so far.
P.S. Using windows 10 my connection to the internet was really stable, so it cant be a network card issue.
edit: P.S.2 Rescan for wireless networks does nothing

Did you happen to do the antenna test? Most people need to use the ant_sel=2 to get decent reception
