Not connecting/working wifi

[Axoner]

Hi, i've been reading if someone already had my problem and didn't found anything.
My wifi worked perfectly and suddenly after trying to set up something from the eth0 i think that i changed something from the wifi. Actually i don't know if it was me or if it was something different, because the wifi stopped working for windows to (i have an ubuntu Mate partition and a Win on the same disk). I tried reinstalling ubuntu and windows but it didn't worked. The only way i can have an internet connection is through ethernet.
Sometimes the connections tab shows:
-Wifi networks:

-Sometimes: Wifi disconnected

-And now: Wifi device not ready

In most posts people who wanted to help ask for:

Thanks in advance for the help!

Hi @Axoner,

what version of UM are you using and is this a USB WiFi stick, have you tried using a different USB port if it is?.

See my answer to this poster -

Wifi speed only 6Mb/s

Perhaps you could put your question to the ubuntu forums site - https://ubuntuforums.org/forumdisplay.php?f=336 They will want to see the results of their wireless-info script. See - wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \ chmod +x wireless-info && \ ./wireless-info This will download the script, make it executable, and run it, all in a row.

Good luck @Axoner.

No, it is installed in a partition. I’ve installed UM 17.10.1, but in info says 1.18.0 enviroment.

Hi @Axoner,

try the following to reset the network:

Ubuntu - Reset network settings

Hi @wolfman,
After restarting the network config and the notebook, nothing happened.
Thanks for your help. Still not knowing where the problem is.

Hi @Axoner,

try changing your software sources download location to somewhere else and updating again, I use the “Main Server” myself, if yours is set to your country, try changing it to “Main” per the update guide linked above!.

[Axoner]

Hi @wolfman,

I already tried main and recommended servers. I don’t understand why WIFI stopped working. Now in the network tab the wifi options didn’t exist

Thanks for the help.

Hi @Axoner,

all I have for you is to do a fresh install following this guide if you have a root and home partition:

Install Ubuntu (Mate) using "Something else" method

Hi all, this guide can be used on any Ubuntu based system and is intended for people who have a basic working knowledge of an Ubuntu installation and wish to keep the contents of their home folder after doing a re-install. This guide is also intended for those that already have an existing swap, root and home partition setup!!. If you have not done/never done any pre-partitioning, please see this guide about using Gparted partition editor: See also: https://help.ubuntu.com/community…
