Ever since I went to Tomato from DD-WRT, my router is acting funky. Any time anyone is downloading anything, and this has happened when torrenting something on one machine, another downloading the Star Wars: The Old Republic client, and yet another downloading The Elder Scrolls Online Beta client, everyone else's connection to the Internet slows to a crawl. On a speed test, my download speeds go from their normal 22Mb/s to around 3Mb/s at the most, sometimes ducking below 1Mb/s, and whatever it is that is downloading doesn't move, either. Everything comes to a halt. Even the XBOX 360 can't seem to connect to XBOX Live the first time around, always needing to do the network test first, then connecting on the second try. This happens even with the torrenting computer shut down. It happens with QOS on or off. It happens with any one computer plugged in to the router. The problem vanishes if any one computer is plugged directly into the modem.
Is it possible that my router just needs to be replaced? According to Tomato, the CPU and memory is happy enough, not nearly maxed out. It was acting weird with DD-WRT as well, going really slow with anything wireless, which is why I switched, but it wasn't anywhere near this bad.
Should I try a different firmware version? I'm using Shibby's branch, V 1.28, which is the newest and best version of Tomato out there for the RT-N12/B1, as far as I know. Please, correct me if I'm wrong!
Thank you in advance for any help!
