@Meenakshi: Absolutely any normal human can notice a 100ms lag. Would you watch a television that displayed only ten frames per second?

I'm surprised to hear how widely people recommend the dd-wrt software, because my experience with it has been so awful. Based on the glowing recommendations and constant goading of my friends, I tried flashing my Linksys with it three years ago. The first thing that annoyed me was what @John mentions: the rudimentary UI for the install process quickly fell down, requiring me to telnet into the router and run cryptic commandlines that I had to scour from forums. Some steps required me to retype all of my network information into the router UI, because it got totally reset after each change ("that's the FUN of open source software!" a forum post chipperly declared). After that, I noticed that it was causing strange problems with some of the devices on my network: my TiVo suddenly couldn't talk to anything else, and my XBox had insanely slow download times from Live. So once again I had to go onto forums searching to see if anyone else had this issue. It turned out that this was biting a number of users, but because none of the authors had noticed it on their own equipment, the advice given began with, "first build a JTAG cable and crack open the case on your WRT so you can solder it to the motherboard. Then, download the source code from..." And that's when I installed Tomato instead. I did file a bug report (with a wireshark trace) on the Live issue before deleting dd-wrt. I never got a resolution, but the unqiue email address I used to register on the dd-wrt forum apparently got sold to pharmo and phishing spammers, so at least I hear from them.
