I set up Tomato at home on my WRT54GL. I was so pleased with it, that I had my boss get a WRT54GL (v1.1) to set up in the office so I could use the QoS settings to ensure that our Vonage and SSH connections were stable. I set everything up today, yet I have a horrible problem. Roughly every 2-2.5 minutes, my computer completely loses all connectivity: DNS, HTTP, SSH, pings, everything. At these times, I can't even reach the router, nothing works. This is extremely consistent as I watched the connection for over half an hour and saw it consistently drop around every two minutes. Each of these drops lasts for roughly 30-40 seconds. Oddly enough, my machine never says that it loses the network connection; rather, it just seems like the computer is neither able to send nor receive any data. Eventually, I tested other machines and found the same thing. At the same time my machine would lose throughput, so would the others. I figured that QoS may be the culprit, so I disabled it. No change. I turned off as many services on the router as I could - SSH, Telnet, logging, QoS, wireless, and time sync. This did not make a difference. I used a variety of different traffic-generating applications in different combinations: torrents, SSH uploads/downloads, HTTP uploads/downloads, and no traffic except for pings. No matter what the traffic sources/destinations were or how densely the connection was being used, the same pattern of throughput drops would occur. I monitored the router from both the web access and SSH, and the free memory was consistently high (more than 70% free), connections never went higher than about 400, and the load was always below .1. Of course, when the connection dropped, I wasn't getting updates (SSH would just freeze), but before a drop and after a drop, none of the numbers looked inflated. Oddly enough, with QoS on, the Vonage line is the one exception. Even when no traffic can flow through my machine during a drop, the Vonage line is clear as a bell. Anyone have any ideas as to 1) what may be the problem and 2) what I can do to fix it? Oh, and thank you to anyone willing to read my lengthy description.
