Two routers, one network?

[Harkey]

Since I'm kind of network-challenged, I hope this is not too basic.

I have a land-line with DSL connected to a Westell 327W router providing wireless service to two computers in my home office. I would like to place a computer in an outbuilding but it's too far away for wireless. The outbuilding has the same landline connection, and I have a 2nd 327W that I could use. But the 2nd 327W conflicts somehow with the first.

I've searched Google for answers but usually the answers are too technical for my feeble brain? Can anyone help me with this?

Thanks in advance,

If they are too far apart, the only thing that i can think of one of 3 things

in order of technical difficulty:

1. Get another DSL account (maybe just another modem ?)

2. Get a Wifi repeater

3. Learn about using the existing telephone jacks in your house in a home network... it is very possible but may cost a bunch
