Okay, so I have a WRT110 Linksys Cisco router. Also, I have a Sony Vaio with Windows XP, a Dell Studio 1537 with Windows Vista, and a HP laptop with Windows 7. But thats not all, I also have a Xbox 360 (wired connection) and a Wii (wireless connection). So all in all I have three wireless connections along with two wired connections. Now my problem is when I have more than 2 wireless connections attempting to the one router, the internet goes to local only. This has been a problem even before the Wii and the HP laptop came in (both Christmas presents). I have tried many different troubleshooting methods to fix the problems such as resetting the router, disconnecting it, etc. yet I can't seem to fix the problem.
Any help with this ridiculously tedious problems is a giant help. I really, really need to get this problem fixed..please help.
