Using WPA2, connection issues?

Hey Everyone,
I have just recently switched to WPA2 since my girlfriend said that it is more secure than WEP. However, now when using my Macbook at times it says I am connected with full strength but no web pages will load at all, once I turn off airport and turn it back on, it is fine again for a while. Was wondering if this was a normal mac thing, or should I just change back to WEP?

Also, when using WEP my macbook sometimes would not connect as well and I would have to turn on and off Airport over and over until it would recognize my network and connect. So I am having strange problems either way, is there something wrong with my network or my airport? Also as a side note, my parents dell inspiron laptop has no trouble connecting and staying connected.

Thanks for any help

 

BUMP!

I changed the network to regular Personal-WPA and now it connects, however it still times out at random moments and I need to turn off airport and on again to make it reconnect.

Anyone know any solutions?

Thanks.
