A while back I made this topic:

Linksys Wireless-G SRX Router Problems
many people tried to help me and they walked me step by step through fixing it, but now I finially got it to work!
Here is my solution:
Upgrade to 2.0!
After I upgraded to 2.0, my internet worked fine on my PSP. All I did was scan, select my router, set everything to "easy" and "automatic" and then the connection succeeded!
So, for everyone out there who was pissed off that their PSP didn't work with your expensive (well, not AS expensive as it once was) SRX router, now you can get it working, too!
