Hello Linux Users.
In this article i will show you how to fix the slow connection problem when using wifi on Ubuntu 13.04 Raring Ringtail, Ubuntu 12.04 Precise Pangolin or Linux Mint 13 Maya.
Method 1:
$ sudo su
# echo "options ath9k nohwcrypt=1" >> /etc/modprobe.d/ath9k.conf
Reboot and check if the problem is fixed. If this did not help, try doing the things listed in the second method.
Method 2:
This method forces iwlagn to not use n. The settings are not persistent, if you notice that the wifi connection works better, make this permanent.
$ sudo rmmod -f iwlagn
$ sudo modprobe iwlagn 11n_disable=1
If this improved your wifi connection, do this to make things persistent:
$ sudo su
# echo "options iwlagn 11n_disable=1" >> /etc/modprobe.d/iwlagn-disable11n.conf
If this trick did not help also, go to method 3.
Method 3:
Deactivate IPv6 support:
$ sudo su
# echo "#disable ipv6" >> /etc/sysctl.conf
# echo "net.ipv6.conf.all.disable_ipv6 = 1" >> /etc/sysctl.conf
# echo "net.ipv6.conf.default.disable_ipv6 = 1" >> /etc/sysctl.conf
# echo "net.ipv6.conf.lo.disable_ipv6 = 1" >> /etc/sysctl.conf
Hi,
None of these worked for me 🙁
Just installed a fresh Ubuntu 13.04 with an “Intel Centrino Advanced-N 6230” wifi card and googled all day long to find a fix for this bug.
Thanks anyway.
Axone,
I have laptop with Ubuntu 14.04 + Intel 6230 WiFi.
Tried different kernels and found that 3.13.6 don’t limit the speed over wifi.

Could you give any explanation about this issue to us?
Method 1 worked to restore my connection. Thanks a lot!
I didn’t want to change anything on the router since there are other users in the home, so I used #3 and I noticed an immediate speedup after reconnecting to the wireless network.
thx a lot! U solved my problem.
