Question Wifi Internet Connection is slow after installing linux mint serena 18.1 cinnamon 64 bit


Hi Everyone,

I am new to linux and it appears my internet connection is extremely slow after installing linux. I assume there's some driver issue? The wifi router is nearby, and I've check the connection with my android device and its working fine but my laptop have some issue with slow connectivity. I am using MSI Gx660 and my wifi card is Intel Wifi Link 1000.

I appreciate any help and I am not familiar with the linux command as well.

Have you tried running one of the free web speed tests e.g. speedtest.net on your laptop, another laptop with a different operating system, and your android device to see what the results are?

Have you also tried using a different browser, or the same browser that you're using at the moment with no extensions?

Hi Hydrurga,

Thanks for the reply. To answer your question, yes I've tried with both chrome and firefox. I am using speedtest.net to test the speed. I tried speedtest on the windows OS laptop and the average download speed is around 30mbps same/close result as the android device. But with the linux OS, I only got 1.5mbps.

Are you dualbooting windows and Linux or are they on separate computers?

Nope. They are different computers. The laptop i'm using now is purely linux. No dual boot.

I would try booting from a live USB on the linux laptop and test your speed from it so we can determine if it's a hardware problem or something else

Can you post the output from inxi -nz and sudo iwconfig. You may want to redact the ESSID name in the latter for privacy. Thanks.

Thanks. I'll have to leave it to the experts to analyse that more fully. However, that bit rate is pretty low (you could try using iwconfig to set it higher, but append "auto" to drop back if necessary, to see what the result is) and it might also be worthwhile investigating "Invalid misc" further. You could also try turning power management off.

See man iwconfig or http://www.linuxcommand.org/man_pages/iwconfig8.html for further details.

According to this page - https://wireless.wiki.kernel.org/en/...rivers/iwlwifi - your wifi chip's driver and firmware should already be in your kernel (unless for some strange reason you're running a really old kernel).

I'm really sorry that I can't be of more use than that, but hopefully someone with more knowledge than me will step in.

Thanks a lot for the help. I will try to investigate the iwconfig and check the kernel version for now.

I've tried executing below command but it appears its not changing the rate or there's no effect.

sudo iwconfig wlp6s0 rate 54M

Ok. Have you tried anything else? Also, can you try connecting by wifi to another router somewhere else, so that we can rule the particular relationship between your wifi card and your router out of the equation?

Yes I've tried connecting to other wifi source but the problem still persist. It's only getting around 1.5-2.3mbps. So I suppose it has nothing to do with the router and that this is more of a driver issue.

Hello and welcome to the forum

Glad it's working better. If you would, please mark this thread as "SOLVED" by clicking on "Thread Tools" directly above your initial post. Thanks!

If the problem returns, please try The EzekielProject's suggestion and see if it can be duplicated live and/or on another (live) distribution.

Regards...
