Ever since I’ve installed Ubuntu MATE, I’ve been having some serious wireless connectivity issues. The connection randomly drops, then when I attempt to reconnect it, it hangs and never connects until I either reboot or suspend, and even then it doesn’t always work. Anybody have this problem or a solution?
i myself am having troubles too
same laptop with windows7,8,10 works fine
installed ubuntu-mate 15.04 and wifi strength goes down by half and reconnects every few minutes
it could be a driver issue
That’s what I was thinking, but I updated my drivers to no avail. And yeah, sometimes it shows it’s half connected but it doesn’t work.
Hi chaps, do you have your software sources download location set to “Main”?:
Try changing the download location and run another update using a NETWORK CABLE!. 
No luck. Still having the same issue.
What wireless card are you running?
Try the Windows Wireless Tool:
I have just installed ubuntumate and I am experiencing the same problem. I have tried many solutions in ubuntu however none of them worked.
I can only connect via LAN.
This is my network information. I hope someone here could help me.
