Problems with Intel Centrino Ultimate-N 6300...

LegionOfHell · 08-05-2020, 05:23 PM

I edit /etc/modprobe.d/iwlwifi11n.conf like this:

when I set: options iwlwifi 11n_disable=8 I get high speeds but i have connection drop outs..

when I set options iwlwifi 11n_disable=1 I get slow speeds but there are no drop outs...

How can i get high speeds with no connection drop outs ?

I don't know what your problem is - and maybe someone will come along with a solution.

In the meantime, I have this link in my favorites and I consider it one of the most helpful links with regards to Linux and wi-fi issues:

https://support.system76.com/articles/wireless/

There's a lot you can try and, in my experience, one of those options will get you to a point where you're satisfied with the results.

LegionOfHell,

Problem solved at post #2 here:
https://www.linuxquestions.org/quest...-a-4175599455/

There is no need to install gksu. Use either gedit or nano.

Like EvanShaw, you may wish to send us your info from this wireless script:

https://www.linuxquestions.org/quest...-a-4175599455/ << I have already done this, it did not resolve the issue...as i explained above:

when I set: options iwlwifi 11n_disable=8 I get high speeds but i have connection drop outs..
when I set options iwlwifi 11n_disable=1 I get slow speeds but there are no drop outs...

Here is the wireless-info:

The file iwlwifi-6000-4.ucode is in my /lib/firmware and /usr/lib/firmware but it is not in my wireless-info...could this be the cause ?

if you go here: https://www.intel.ca/content/www/ca/...etworking.html

Scroll down to: Intel Centrino Ultimate-N 6300

and download the latest firmware: iwlwifi-6000-ucode-9.221.4.1

This archive contains the iwlwifi-6000-4.ucode file which is identical to the ones in my /lib/firmware and /usr/lib/firmware folders(same size)....but wireless-info does not report that this firmware is in use...what do I do ?

EvanShaw has the iwlwifi-6000-4.ucode in his [iwlwifi] section...but I do not...I have the iwlwifi-6000-6.ucode which is not for Intel Centrino Ultimate-N 6300 according to Intel's firmware web site...should i just delete iwlwifi-6000-6.ucode ?

LOH,

According to the README.iwlwifi-6000-ucode, which you have probably read, the firmware is in the correct position:

Quote:

Installation of the firmware is simply:

% cp iwlwifi-6000-4.ucode /lib/firmware

I don't know why this is not appearing in your wireless-info.

Sorry, but I am not prepared to take a guess at the answer.

Any wifi experts ready to contribute?

How can i get high speeds with no connection drop outs ?

Have you tried other values, namely 2 or 4?

I just tried 4 but the download speed goes from 85mbps to like 38mbps..better than 1 but still.

Is there a way to keep it at 8 and eliminate drop outs ?
