My friend has a crappy wireless router, and I live 3 apartments away, too far to use his network. I bought a Cisco E2500 and 200 feet of CAT5 cable. I ran a line from one of the 4 ethernet out ports on the back of his router, out the window, across the roof (involving some night-time ninja-work) into the internet in port on the back of the Cisco.
I then followed the instructions in this post, changing the IP address of the router and turning off the DHCP server. I set up a WPA2-personel network on the Cisco, and can log onto it, but cant get on the net. In addition, his computer now gets pop-ups saying that another device is using the same IP address as his.
1. The "basic setup" has four connection types: which should I use:
•Automatic Configuration - DHCP
Well, long story short, I was going to take up the cable and plug it between my friends router and computer to test it, but he said, "Just plug it into your computer, not the Cisco router" and I did and it worked. Then I plugged the cable back in and lo and behold, the wifi worked! When I looked down, I had accidentally plugged it into one of the ethernet slots instead of the "internet in" plug.
Whatever, it works now. Just having some IP address problems on HIS router now...
