Really slow wireless internet on ubuntu 11.10

[kforum]

I've tried the above steps of disabling IPV6. For some reason, my Ubuntu 11.10 Wireless is still slower than Dial-up. This issue is driving me nuts. I appreciate your support.

have you tried using the 2.6 kernel?

[wildmanne39]

Hi xchecker, let's do it this way since it is not working the other way.

gksudo gedit /etc/pm/power.d/wireless

(this will create or edit a configuration file that will override the default powermanagement behavior) and enter the following:

#!/bin/sh

/sbin/iwconfig wlan0 power off

Save, exit gedit and reboot.
Thanks

Hi and1script, yes it is hardware dependent, so please post the output of:

cat /etc/lsb-release; uname -a
lspci -nnk | grep -iA2 net
iwconfig
rfkill list all
lsmod
lsusb

by clicking on new reply and click # and paste the information between the brackets.
Thank you

Hi Martian1567, please do what I said in post 103.
Thanks

Hi and1script, please try:

sudo ifconfig wlan0 down
sudo rmmod -f iwlagn
sudo modprobe iwlagn 11n_disable=1
sudo ifconfig wlan0 up

if it helps we will need to make it permanent.
Thanks

Hi Martian1567, please see if this helps:

echo "net.ipv6.conf.all.disable_ipv6=1" | sudo tee -a /etc/sysctl.conf

reboot.
Thanks

[xchecker]

Wildman -

OK, we're getting closer. I created the configuration file you suggested and rebooted. Now it takes 15-20 seconds to load a page rather than several minutes. Still slow, but much improved. Can we do better?

I really appreciate your efforts here.

Update - Well, maybe not as improved as I thought. The first time it loads a page it takes maybe 30 secs, but then after that it's taking several minutes again to reload or to follow a link at the same site. Definitely frustrating.

[wildmanne39]

Hi xchecker, in post 89 in the screenshot I gave you it showed dns server set manually to several 8's did you change that also to match mine?
Thanks
