Another PS3 problem

[The_Dealor]

I cant get my ps3 online, at all. tried looking through all of the settings etc and it wont work, cant obtain an ip address or something.

i no little about this sort of thing, im using a webstar cable modem, perhaps thats the problem?

i am planning on buying a router in a few days, but is there no way i can connect with the webstar until then, even if that means not being able to use internet on my pc until then that is fine.

any help would be much appreciated.
