You need to get a new router or try limiting the number of connections as you read at http://www.azureuswiki.com/index.php/Bad_routers
This is a very well known issue.
I currently own a D-Link DI-624M which is giving me a lot of problems, I have to unplugged the router a lot everyday because reseting it from within doesn't work most of the time, I use azureus a lot for file sharing and my connection drops a lot because of it. It's obvious that it can't handle the load. So I know the cnet crew is not a fan of the new routers with pre-N technology but I really need to find a quick solution to my problem. Is there anything out there that can be recomended. My network consists of 4 wired computers and 3 wireless equipments including a video game console and laptops.
