What’s the best way to increase the range of my 802.11g router?
My wireless router does not cover my whole house... Can I do something maybe with multiple routers, perhaps wired to each other?

Instead of a wireless repeater, you could replace your router's antenna with a more sensitive one, and/or boost the signal output via a 3rd-party firmware. This won't extend the range as much as a repeater, and not all routers have replacable antennae or chipsets that support signal boosting. But it's an alternative for sites with the right equipment where you just need a liiiittle more range to fill in the gaps.
See A Dwarf's answer for a cheap DIY antenna replacement.

My +1 goes to ~quack and derek posts. But I feel I should also include here a third option which may entice those of us who like to get our hands dirty. You can make your own antenna extension with a screw, some copper wire and... a drinking straw.
Now, I'm not much into derisory claims without having tested it myself. And I did, And I was able to extend the range of my D-Link DVA-G3170i ADSL Router to cover the whole house. Although to be honest I was missing just a few divisions on the far side, around 10 meters that I needed to gain.

nice solution: Apple Airport
Apple sells a nice combination solution for this. The Airport Extreme works as the primary base station, and the Airport Express works as a repeater station. It supports any computer that uses wireless (including game devices) and can be set up from both Macs and PCs.

For best results draw a straight line between the antennas and minimize the thickness of any intervening material. Remember that a wall crossed on an angle is much thicker than one straight on.
