iPod Touch Internet Slow

I recently bought an iPod Touch and everything was working fine. It wasn't until I found out that all of my internet applications were running/connecting at a very slow speed with my connection, that I started becoming a little curious on to why this was. I'm using a Linksys router (will add version (if needed) when I can) that normally runs at a steady connection speed of 54.0 Mbps. I can access every page (that I normally visit) just fine, but this is completely different on my iPod touch. I connected to my internet connection using my WEP key, and am able to load www.google.com just fine. I can ping my iPod from my computer with 1/3 packets going through. I can also ping my gateway from my iPod with 3/3 packets going through. The only website I can access without a problem from my iPod is Google - anything else takes quite a long time (a few minutes (which is quite long for internet)).

The odd thing about this is that when I connect to my friend's unsecured internet connection, all the apps and websites load just fine; they only take a couple of seconds.

I did a little test on my internet connection. I changed the type of encryption from WEP 64 to WEP 128 to WPA, and they all didn't change the speed of my iPod internet connection. I did remove the security encryption completely and connected with my iPod, and everything was able to load very quickly.

Now that I know that it's the encryption, can someone explain to me why this is?


Any help is greatly appreciated.
Thanks!
