Slow connection when using PIX 501. Reboot fixes temporarily.

[dcusher]

I think this issue is being caused by something with my config. I am having to reboot the PIX once or twice a day to get bearable speeds. I have connected to the modem directly and have had a consistently good connection. The PIX will give me a decent speed for 4-5 hours before dropping down below 1 mbps.

Sorry if this question has been asked before. I found some similar threads on the forums but had no results.

I am using comcast cable as my ISP. This is a residential connection.

Here is my config:

I'm fairly new to this, but technically capable of troubleshooting. Thanks for any help you guys can give.
