"A good starting point"3.5 starson by netghq
Pros: 3rd party firmware
Cons: Only 2 antennas
Summary: I bought this router last week, to replace an aging WAP54G as an access point. It took a few tweaks before it performed as it should...
First of all, stock Linksys firmware is buggy, unstable and fairly limited. I gave it a fair chance, just left it at that for a couple of days before I got tired of my wife complaining that wireless keeps cutting her off all the time and the signal is abysmal in some parts of the house.
So... in went DD-WRT, which (once again) proved to be very stable and, with a few adjustments to wireless properties, extended the range considerably. The sweet spot of txpower vs. noise seems to be around 100-120mW. Antennas aren't very good and there are only two of them, compared to three in higher-end WRT300/350 routers. That seems to make a difference and once I'm convinced that I won't need the warranty, I'll probably de-solder the internal antennas and install two RP-SMA connectors in the back of the unit. That, with quality 7-9dB omnidirectional external antennas, should boost the range noticeably.
Without DD-WRT support I would have not bought this router. Replacing antennas isn't that difficult but it'll void the warranty and unless you have some experience with soldering electronics, I wouldn't recommend trying to do it on your own. All in all, this is a great, cheap router as a starting point for a build/mod project, but off the shelf, it's both unremarkable and mediocre value for money.
Buffalo WZR-G300N and Linksys WRT300N may be a bit more expensive but far better routers out of the box, not to mention multiband routers like WRT610N or D-Link 855.
