Misc Can't connect for no apparent reason

[teonintyfive]

I don't get it, everything is fine, but my wii can't connect. Neither my DS can. It worked like 6 months ago (DS, I got my wii about 4 days ago) but now...
And I haven't changed any settings on router. Everything goes fine on both consoles, but it can't connect to the internet. Even when the PC's off. They catch the router, and then error.
Halp me and I'll hail you

Are any filters at all on your router (maybe MAC filters) ?

WEP key is correct?

Any new 2.4 GHz devices nearby?

Tried changing channels on your router (to 11 or 1 instead of 6)?

Are you using a software firewall? That could be blocking it.

close your firewalls and maybe check if you have closed ports which are neccesarry for the Wifi connector

Firewalls closed, no wifi connector, no MAC filters, no nothing. A friend on another forum told me to change the settings from 802.11g to 802.11b

Tried setting manual IP addresses for the Wii and DS?

I tried it all.
NOTHING WORKS!
