    Thanks in advance.

    I have ran Tomato 1.25 on a year old WRT54Gl router for about 6 months. Recently I noticed a "slow down" and tested the speed and ping. The ping inside the home network is great but outside traffic is slowing down. I have a cable modem with home cpu lan connected. The wireless connects to my phone and work laptop when needed. When everything is working as it should I will get ~7-9 Mbps down/.43 Mbps up, with the ping of 30-50ms.

    Here recently the traffic has slowed down to 2Mbps down/.2Mbps up, with latency ever increasing (100-999ms).

    If I reboot the router it solves the problem for about 10-15 minutes and tjen the problem gradually creeps back. I can run ping test and actually see the ping time increase as it goes.

    I have tried hard rebooting the router and only changed the Wireless name and password, set up an static IP for gaming (including DMZ) and the problem always returns. After the hard reboot it took longer to slown down but still did after I checked a hour or so later.

    Edit: Forgot to mention that this slown down is seen when pinging from lan connected cpu or wireless.

    Any thoughts or suggestions would greatly appreciated.

    Although the wrt54GL can track thousands, default being 4K connections with its 16MB memory, it will ONLY allow several dozen simultaneous connections, blasting away at data in both directions at high speeds without much latency. Also wireless connections causes the drivers to utilize quite a bit of cpu. First indication being horrible latency. Your needs may be at a point where this router hardware is no longer sufficient. Try one of the newer 802.11n tomato routers.
