Wi-fi shuts down itself after upgrade to Cinnamon 17.3

Post by marso »

In fact, internet is unusable now.
Any fix, please?

Hi,

I have been struggling a lot with the intel ultimate-n 6300 card in my x201 system too.

I found a redhat bug #785239 on the ubuntu forum that may be related. I followed the advice to try to disable 11n in the modprobe config. It did not permanently solve my problem. I have been having a lot of firmware load issues pop up in /var/log/syslog.

In other forums i've read that users suspect the intel firmware for linux is a poor standard. You can grab the latest versions here
http://linuxwireless.org/en/users/Drivers/iwlwifi/

If I can find out more i'll post again.

Here's an example of a successful load on my system

** actually i just read here that it's supposed to work better with iwlagn. Maybe a regress would work best.

Re: Wi-fi shuts down itself after upgrade to Cinnamon 17.3

Post by jimux »

Thinkpad X201 with Centrino Ultimate-N 6300 card.
I had wifi problems. Running 17.2 since it was released, and over the past few months the wifi would increasingly frequently drop out.Never had a problem when originally installed. When I lose connection the wifi applet show a reduced signal strength of all detected routers - mine plus several others.
Many other forum report similar problems with this laptop/wifi combination, including Windows, so I decided to check the release version of the board. When I removed the screws securing the keyboard and palm rest.I noticed some fine rust on the screw threads. Obviously the machine had been stored in humid conditions some time.
The wifi card is just below where your right palm rests when typing, with two screws and two press-stud attached aerials. (there is a third loose black lead which could go to the middle stud, but it was after I had re-assembled that I read that it would improve 5Ghz signal strength).

I carefully removed the card and cleaned the contacts with an eraser. A typists erase that looks like a pencil but has a rubber core is ideal. Gently rub until all contact surface looks bright. Then reassemble, pushing the card hard into the slot while tightening the screws. Press the aerial studs back on with a bit of a wiggly to make a good contact, and replace rest and keyboard.

I've used the machine every day for a fortnight since without the slightest problem. Most days it's on for 6 to 8 hours, but one day I ran it for 13 hrs. No drops, no lost packets, and a number of multi-Gb downloads to test.It's talking to a Belkin AC1000 at 5Ghz at home and other routers elsewhere.

My conclusion is that the problem is one of degraded signal, caused by tarnish, affecting signal strength and introducing a capacitance lag that messes up timing. Many years ago I supported IT systems and experienced similar problems with ethernet cards. I hope this helps others.


EDIT:
Still perfect after 6 weeks use.
