I'm a cable lover as well, the wireless network in my parents' home shows similarly fluctuating "qualities" and I find it quite bad to be disconnected 1-5 times in an hour, sometimes more often. It may be good for big public places etc, where there are no walls obstructing it, but at home, I'd rather have some cables lying around(last time I visited my parents I simply plugged one of those 10m cables into the laptop because the WLAN connection was so horrible). And I'm not sure whether I'd want a really powerful access point for the same reason that I don't want to be in a microwave oven when it's turned on.
