I've spent a reasonable amount of time tweaking my configuration and WRT54GS router. Besides the configuration on my PC, I've played with the most popular third party firmware, stuck with HyperWRT Thibor because of the stability and features, tweaked it for P2P, followed Nate Hoy's suggestions on QoS so Skype, BitTorrent, and web surfing coexist with reasonable performance... and today, everything suddenly is noticeably faster and better. What'd I do? Replaced my cable modem. I've had my RCN-supplied 3Com HomeConnect "sharkfin" cable modem for about two years now. No really big issues, but I got sick of paying the rental fee and picked up a Motorola SB5120 at Circuit City today. And... - BitTorrent downloads are faster - Skype sounds better, much! - web surfing is snappier I had previously used the Speakeasy Speed Test to check my download and upload speeds. I have 8Mbps/768Kbps service, and I would typically get a download speed of 5.5Mbps-7Mbps, and upload speed of 450Kbps-690Kbps, but the results varied all over the place. Now, just about every time it gives 7.4Mbps/740Kbps with almost no variance in the results. Best upgrade I've done in a while. Even the sky seems a brighter shade of blue.
