wireless performance tips for Waldorf

Hi everybody,

I just made the switch to #! and i had a lot of trouble with wireless performance. Connection to the AP was always good but the connection would just drop from time to time, or become really slow.

Just to be thorough, i am on: Linux crunchbang 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2 x86_64 GNU/Linux (waldorf)

I tried a lot of things, even bought a PCI card to replace the USB dongle i had. That worked great for about a day until speed dropped to zero again from time to time. It was really annoying.

What did the trick for me was disabling IPV6. My connection is now faster and stable. I know this is a stopgap solution, but i think it is a safe bet this will be solved when i need IPV6.

Here's what i did: (thanks : https://joshlefler.com/2013/01/20/disab … n-wheezy/)

$sudo cp /etc/default/grub /etc/default/grub/old
$sudo nano /etc/default/grub

in nano:
replace the line
GRUB_CMDLINE_LINUX=""
With
GRUB_CMDLINE_LINUX="ipv6.disable=1"

Save and exit (ctrl+o, enter,ctrl+x)
$sudo update-grub
$reboot

Now ipv6 should be disbabled, and for me this resolved all my wireless issues.

hope this helps someone!

Cheers

Guido

Mind posting info for your wireless card?

lspci -knn | grep -EiA2 net

Perhaps disabling IPV6 for your connection works too and is less intrusive?

sure! It is a pci card, this is the output of the command:

So after my initial success, one day my wifi just died. It did connect to the accecs point but there were no packets being sent or received. Changing my WPA2 encryption from AES to TKIP solved the issue. Anybody else experience this?

I think a wlan-router problem.
