I got a DSL modem with an integrated gateway. It is the 1701HG from 2Wire.
I also have a nice DLink router that I used to use with DSL modem-only. But recentely, got the "new" 2Wire provided as a free obligated upgrade from my ISP.
Somehow, I'm not convinced of the 2Wire gateway capabilities. Sometimes I have problems to find the other 3 pc's arround the house. It is like if it works just randomly.
So I'm thinking to use the DLink router as hub and maybe as dhcp. I'm not sure if this is possible at all, nor what exact functions should I take from each device in order to get it working, all trying to get the reliable intra-home networking I used to have.
