You can set up a second one as a repeater if you really feel like you need to but I'd personally only consider it if I was getting fairly unusable connections. Have a look at this and see what you reckon: http://www.techrepublic.com/blog/doityours...eless-range/141
I wouldn't focus on the number of bars you're getting. That only relates to signal strength and may not be an accurate indicator of speed (although poor signal quality can have a flow-on effect on speed but that is not to say they are always the same thing). Try www.speedtest.net and see if you're getting speeds like you might expect.
At the moment I'm getting 7Mbps via WLAN in the bedroom, is that good / average / hohum ?
Seems to be chugging along nicely playing a show on ABC's iView - Thanks for that article, Bum, that will be plan B.
