DD-WRT v23 SP2
I installed dd-wrt on my Linksys WRT54g because I was having problems with the Sveasoft Alchemy firmware. The wireless was dropping constantly, which can be real annoying when you're trying to do a video call on Skype. My suspicion was that the firmware image was too large and too many services were trying to be run at once, and the unit was running out of memory.
Once long ago I had problems with the Alchemy firmware getting an IP address from my DSL connection. I managed to get syslog working (shouldn't have been hard, but it didn't work well with Alchemy) and the errors seemed to point to the fact that the unit was running out of memory. It would eventually work, it just took 20 minutes to get an IP address after it booted. Then it would stay up for months.
I guess I've just been out of the loop with regard to the newer firmwares. dd-wrt has much of the same basic functionality in their 'mini' version as the Sveasoft Alchemy fully featured version did. And to think that at point I paid for Alchemy because I wanted a more featureful, stable firmware :|
The wireless issues have gone away, and the web interface has a much more polished feel to it. I like logging into the router just to look at the interface and see the random stats. It also gives you status on the signal strength of the wireless clients, which can be very useful!
The dd-wrt firmware is famous for being able to do client mode bridging, i.e. act as a transparent wired-to-wireless bridge. I'm looking forward to trying that out some day.
By the way, although my unit will broadcast at a power of 251mW, I read on the dd-wrt wiki that 84mW is ideal for most hardware in terms of getting the best signal-to-noise ratio. At 84mW, I get a SNR of somewhere between 30-40, so I feel like that is probably pretty accurate information, considering I probably only need a SNR of 10-15 to get a very good wireless signal.
Try out dd-wrt today!
