Ubuntu 16.04; No wifi

**jellman2** · August 19th, 2018

Hello All,

I hope someone can help me out; I have very basic knowledge of Ubuntu.

I have a HP Pavilion 20 All-In-One and very recently updated to Ubuntu 16.04.

I only recently updated to 16.04 because when I previously installed updates in 14.02 (a few years back now) I lost wifi capability (so I did a factory reset and used the machine without ever adding updates). Anyway, so I put off installing until the lack of updates effected performance, so I finally installed the updates a few days ago and then updated to 16.04. Everything was working fine; I should have stop with the updates at this point.

However I then started to get a problem installing other updates which seemed to relate to the realtek wifi car; I searched the forum and found some instructions which seemed similar to my problem. But whatever I entered into the terminal has lost wifi capability. Now I'm not sure what to do; wifi doesn't work at all. Can anyone give me any help ?

I know I haven't included any technical information (but if you can tell me what you want; and the commands to get it) I'll respond.

At the moment I've moved the computer near the router and connected by cable; but it's not practicle to leave it in that location; I would greatly appreciate any help you can provided (and I'll thank you in advance for you patience).

John

Hi, kernel 3.2 doesn't ship the driver, it needs to be installed by hand:

Thanks for this. Sorry to ask what I assume is going to be a stupid question, but... Do I paste the whole things into terminal or do I past each line seperatley then press return ? (If I paste all text at once, I only seem to see part of the text in the terminal and it doesn't seem to work but when I do it line by the line it seems to come up with errors). I'm clearly doing something wrong can you give me some guidance. Sorry about this.

**jellman2** · August 20th, 2018

Update; I managed to install 18.04 via the Terminal (as it wasn't offering the update in software updater). This has reinstated wifi (although I still have another problem which if I can't resolve I'll ask in a different thread).

Anyway thanks to those that responded.

Issue Resolved.
