I'm trying to make a long-range wireless access so that i can access my home cable connection everywhere on campus (< 7 miles).
As of now my networking equipment is:
SMC 7004AWBR Wireless router
Lucent Orinoco Silver PCMCIA
From what i read on this site, one way to extend the range of the connection is by getting a Yagi Antenna

Since there is no way to connect an extender antenna to my current router (The antenna is not detachable), I have 2 options now:
1. Get a D-Link router, and get the yagi antenna connected to the router
2. Get another orinoco card + PCI card, put it on my desktop, connect the yagi antenna to it... and use ICS.

Now i think the 2nd option is more effective, but would ICS work this way? W
ould this scheme work if there are obstacles in the line of sight? I live a 3-floor apartment and of course, line of sight to the campus is blocked by trees, buildings.
