I have a wireless network in my office (using a Linksys Wireless-G router). My appartment is in the same street, on the same side of the road, about 25 meters away. The buildings are old and have one foot thick stone walls. Forgive my for my ignorance if what I am about to say is rubbish... The Linksys router has two aerial fittings on the back. I figure I can unscrew one of the aerials, attach an extension cable, buy an outdoor aerial and put it on the outside wall of my office building. That should be enough to get the signal to my flat window about 25 meters away (with clear line-of-sight). Then what I think I need to do is have another exterior aerial on the wall of my appartment, to send/receive to the one outside my office, and then have the cable from that go into my appartment to another wireless device which would broadcast the signal for my appartment. My aim being of course to be able to access my office network from my appartment. Does that make sense? What would the second device have to be? Are there any web pages anywhere that describe how to do this kind of setup? I've Googled but I'm not quite sure what I'm searching for. (I have considered running ethernet or optical cable along the front of the building but it would be very problematic as they are historic buildings and I probably wouldn't be able to get permission from the other property owners). Many thanks for any help you can give.
