My brother bought an Xbox 360 and for a microsoft product, it is quite impressive (other than the novelty-sized power adaptor). Anyway, he has the pismo (in sig) and I tried to use that with an ethernet cable to give it wireless internet, but it didn't work... First I went to preferences/sharing and turned on internet sharing through ethernet. Then I gave the xbox a unique IP address, like 192.168.1.128 or similar. I then made the subnet mask 255.255.255.0, but the gateway thing confuses me, I can enter a random number, but it does the network test and says "IP address -Failed". If I click more info it says the gateway is incorrect. On my router page (192.168.1.1), the gateway just says 0.0.0.0, but the 360 will not allow it to be 0.0.0.0 Any ideas?
