I was away for 2 days, and when i came back, my mac couldn't go online. Having investigated, I've found that my PS3 (wired) and PSP (wireless) can still access the internet via the router. My mac cannot.
If I try accessing the router directly (using the usual default IP address - can't remember it off the top of my head), then the Mac says it can't acces that address/can't see a router.
If I take the ethernet cable from the back of my router, and plug it so that the internet is routed out of the wall, through the modem, and directly into the ethernet port on the mac - the internet magically works.
What the flippin' flip has happened?
I have tried all the obvious turning off the router, mac and modem, and this has done nothing.
It is a linksys wrt54gs router (v5.1, by the way. The firmware seems to be unavailable.) The modem is an NTL modem (cable broadband). I am running OS X Leopard.
