so i have an ipod touch for a while now and i have a problem thats making me sorta mad. I have wifi in my house but the problem is is that its is way too slow. I have comcast cable internet. What's wierd is that my girlfriend has the same internet provider, but when im at her house the wifi speed is super fast. Do you kow how i can fix this? or is there anything i can buy at best buy or something to increase the wifi speed? thanks!
