Very slow web browsing on wifi connection

Hi,
I used Arch a lot some time ago but never on wifi, my network was always cable. Now, I've got only wifi connection.
I'm not sure it's a wifi problem or just networking, but I've never had that kind of problem on cable connection.

All config files are on the bottom. The problem is, but not always, sometimes it just work, that DNS resolving takes really long time (about 6-7 sec) and webpage, image, audio, video load very very long (ie. 1MB photo about 2 minutes, I have 4Mb connection). It doesn't matter what DNS is used. What's interesting, download rate is very good ie. in KGet about 560kB/s. I'm sure it's configuration problem because on Windows everything is fine, but I have no idea what I've done wrong. Any ideas?

Iwconfig & ifconfig:

lo        no wireless extensions.

eth0      no wireless extensions.

          RX bytes:218181679 (208.0 Mb)  TX bytes:7806332 (7.4 Mb)

I have static IP configured in rc.conf:

wlan0="wlan0 192.168.2.50 netmask 255.255.255.0 broadcast 192.168.2.255"
INTERFACES=(wlan0)

And static DNS in resolv.conf (actually Google DNS, but also tried OpenDNS, my provider DNS):

nameserver 8.8.8.8
nameserver 8.8.4.4

I have ipv6 off:

#
# /etc/modprobe.d/modprobe.conf (for v2.6 kernels)
#
# disable autoload of ipv6
alias net-pf-10 off

And I run my wifi connection using wpa_supplicant:

wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -B

Re: Very slow web browsing on wifi connection

Does it make a difference if you use ip addresses instead of urls?

Maybe try "ping www.google.com" and then "ping [google's ip]"

And see if there's a difference in speed. You could assign some ips locally for faster lookups.

try "host www.google.com" and see how long it takes.

I would have suggested opendns, but you've already tried all that!

Also, try connecting to your router's setup page. If that's slow then you know it must be the connection to the router. If not then possibly dns or something else.
