So I live in a long, narrow apartment. My office is at one end and this is where the cable modem lives. It's hooked up to a Linksys wireless router (model BEFW11S4) which distributes the internet connection to a few computers via good old ethernet cables with RJ45 connectors and also to our iPods and laptops via 802.11b WiFi.
The problem I have is that the wireless signal doesn't reach the other end of my apartment where the TV room is. I would really like to get WiFi working in there.
I feel like I should know the answer to this question but feel compelled to try and verify it first. If I put on my coveralls and crawl through the basement and run a 100-ft ethernet cable from one of the 4 computer connections on my existing Linksys router into the TV room and plug it into the jack that says 'Internet' on some other wireless router, will that succeed in establishing a second WiFi access point in my TV room? It seems to me that the DHCP service of my first router should properly delegate some IP address to the new router in my TV room, but before I go and buy a new router and huge ethernet cable from newegg and start crawling around in all those spiderwebs, I'd like to ask the community if they think it will work or not.
Also, is 802.1n worthwhile? Better? What about 802.1g? Obviously, any hints about which router to use would be appreciated.
