Newly installed Mint 18.1 and wifi issues

[Io355]

I got a new laptop and installed Mint 18.1 on it and the past few days I’ve been having major wifi problems on it. The wifi constantly disconnects and is extremely slow. It actually seemed fairly fine in the morning and got worse in the evening so I wondered if it had to do with my ISP, but I doubt it. This morning I was having more problems with it. And to make sure I got an old laptop with Windows 7 on it and the connection on it is fine while it’s either not working or extremely slow on Mint.

The connection can actually be fine for a while too, but if I download something even if it’s just MB in size, watch a YouTube video, or install something through the package manager or terminal, the internet will instantly disconnect. Around half the time the connection will come back right away if I disconnect and reconnect, but then a lot of the time it will disconnect again after seconds.

I Googled this and some people said it was because this power manager option for the wifi was on. Mine was on and I disabled it, and it didn’t help at all. I’m thinking the wifi card on this laptop has compatibility issues with Linux, which would really suck since I love Linux. I wonder if anything can be done about this. I could maybe try another distro, but if it’s not supported on Mint I’d be surprised if it’s well supported on something else.

welcome to the wireless forum

wireless folks need facts; like carnivores need red meat! Over on the ubuntu forum https://ubuntuforums.org/showthread.php?t=370108 is this thread and it tells you how to run a script that collects facts on aspects of your wireless setup;

if you run that, and post the way they suggest, you can help folks to help you

At Ubuntu forums they also tell you to dist-upgrade first, which isn't meant to be done in Mint....

The script is OK though. But this might suffice:

a. Please generate an overview of your system like this:

- Launch a terminal window (this is how to launch a terminal window);

- make the terminal window full screen, to avoid chopped lines;

- copy/paste this command into the terminal:

Code: Select all

inxi -Fxz

(if you type: the letter F is a capital letter)

- Press Enter.

- Copy/paste the output in your next message.

b. Do the same with the following three commands:

Code: Select all

rfkill list all

and:

Code: Select all

inxi -Nn

and:

Code: Select all

iwconfig

I'll see if I can get this script working. I tried doing the other things mentioned like updating, but it said everything is up to date.

Try this:

Update Manager - panel: View - Linux kernels

Install the latest kernel from the 4.4 series. Then reboot.

When no avail, try the latest kernel from the 4.8 series.

Switching to the latest 4.4 kernel didn't seem to fix it, but after switching to the 4.8 kernel my connection speed has been fast and hasn't been disconnecting. It seems to have fixed everything. Thank you.
