Issues occur with many routers, including routers running DD-WRT, when using the router with heavy P2P applications. The router becomes 'slow' over time, and restarting helps for a short time. Some symptoms can be:
* Slow web-interface, or cannot connect at all to web interface
* Slowing transfer of data, e.g. browsing, after a reboot
* Not responding to ping
* Router Crash or even rebooting
Usually the culprits are heavy P2P software like Emule, Bittorrent, uTorrent, Azureus, Shareaza or something similar. These programs, by default, can require a lot of connections which could cause the routers' ip_conntrack table to get full.
* Especially BitTorrent's DHT feature sends thousands of UDP packets that quickly overflow this table.
Routers affected with this issue are the most common types of routers running DD-WRT.
