I tried placing my computers on the main network and his on the guest, but then I realized that since he has an older PC attached to the Ethernet jacks on the back:
A) His laptop (now on the guest network won't see his own computer, in case he has any sort of file sharing going on)
B) My computers would be on the same network as his PC, which is precisely what I don't want.
If I could place the physical ethernet jacks on the guest network, then maybe it would work, but I can't.
I doubt my landlord even knows that the router has configuration pages and I don't want to explain to him why I want to move the cable modem and router into my suite from his house (I doubt he would let me either). Plus, then I would have to give him my wireless bridge and I would have to explain to him what that does and he won't understand and OMG what a nightmare that would be.
Oh, and when I try to access 192.168.0.1 from the Guest network, it just times out...
I just want to able to configure the router.
