PS3 wireless connection suddenly stopped after using GT5!

[leothetiler]

Have had my ps3 set up on a wireless connection for about a month with no issued at all, and have had no problems with online gaming.

Last night for the first time went online with GT5. Game lasted about 10 seconds before it said I have lost connection. Ever since then I am struggling to sign in on the playstation homepage. Sometimes it works, but normally only when I have switched off the ps3 and reset the router.

Any ideas what has caused the problem, and how to resolve it. Many thanks!

Have you tried rebooting your router (and PS3) ?

Have you any other wireless devices in range of the PS3? A baby monitor or a cordless phone? A phone with wifi/laptop etc?
It's possible they are interfering with the PS3.
