Slow wifi and random disconnections
« on: January 18, 2017, 07:25:33 am »
Hello! This is my first post in the forum! I use Peppermint 7 and after a fresh install i have issues with wireless! I have attached wireless info script results, in order to give you the needed info!  Finally I have tried many tweaks from other forums such as askubuntu/ubuntu forums but the proplems still remain :(
Thank you in advance for your help!

Welcome to the forum, nastak!   :)   Here are a few basic things you can try...

Left click the network icon in your panel and choose "Edit connections."  In the resulting window, highlight your connection and choose "Edit" from the choices to the right.  In the resulting window, open the "IPv6Settings" tab and in the window beside "Method" (will probably say "Automatic") choose "Ignore."  Save your changes and close. 

Assuming you use firefox, type "about:preferences" (without the quotation marks) in the url window and hit your enter key.  In the resulting window choose "Advanced."  Under "Browsing" uncheck "Use hardware acceleration when available."  Restart firefox and see how it goes.

These are general, basic steps.  If your problem persists please post back.

cheers

Thanks for your response mac! I had the mentioned preferences configured as you told me. So the problem persists. Despite I am connected in wireless, I can't surf on internet as fast as it is possible...  :(

Hi nastak,

You say this is a fresh install.  Have you completed a FULL system update and have you checked for any DRIVERS that may need installing.

Was it all working OK on a previous install ?

Yes I use peppermint about three days and I think I have installed the suitable drivers... In a previous install I experienced similar problems and I had solved them. Now with the same configurations, I experience problems even when I try loading a single webpage, which is very annoying...  :(

Have you tried an online speed test of your connection? If that seems OK, maybe you could try changing your DNS server to see if that speeds things up.

I just tried 2 speed tests: The first one was OK but the second's output was disappointing :(
It had the half of download and upload speed compared to my connection specifications...

a) switch your router to a channel nobody else is using .. say channel 8

b) you have two config files with the same contents
/etc/modprobe.d/iwlwifi.conf
and
/etc/modprobe.d/iwlwifi-opt.conf
so can you delete /etc/modprobe.d/iwlwifi-opt.conf with
Code: [Select]
sudo rm /etc/modprobe.d/iwlwifi-opt.conf

c) let's try adding the swcrypto=1 option, so run:
Code: [Select]
sudo pluma /etc/modprobe.d/iwlwifi.conf
find the line:
Code: [Select]
options iwlwifi 11n_disable=1
and change it to:-
Code: [Select]
options iwlwifi 11n_disable=1 swcrypto=1
SAVE the file and exut pluma.

d) Set IPv6 to "Ignore" in Network Manager.

Now reboot to test.

I followed the steps... Unfortunately same behavior again... I made also a speed test and the results are same as before

Can you say which version of Peppermint it worked in, and post the outputt from:
Code: [Select]
sudo lshw -C network
and from the script you ran in your first post again with the current configuration.

Finally, I have to mention that I could not fix the channel as you asked me to do so. I tried the command
Code: [Select]
sudo iwconfig wlp6s0 channel 8

and the output was that wlp6s0 was busy, or something like that. Is there any other way to change it? I also tried other numbers in the range 1  - 8. I was using Peppermint 7 before ... Now I use the newest edition of Peppermint which is Peppermint 7 respin

I have to mention one more thing: Running iwconfig, I see that if  Link Quality is quite high (meaning greater than 35/70 ) everything works fine (meaning speed test for example). But this value is not stable, so maybe that's the reaason of my problem. Is there any way to keep it high?

I think it's your router you were supposed to change the channel on. Do you know how to get to its config interface (like a web page)?

Yes I tried to configure the channel from the config interface as you mention. I entered the router page by typing the address 192.168.1.1 (right?) , but I didn't manage to do it without disconnecting the other users of the (wireless) network. Is there any way to do so, without disconnecting them?

I suppose they would get disconnected but I don't know if their wifi adapters would find the new channel or not.
