Hi, I have been having a problem lately with my network. I am running Fedora 7 Linux and am connected to my network via a Linksys WMP54G PCI wi-fi card. Randomly, networking just stops working. I cannot go to any websites, ping anything, or reach any networked computers. I tried restarting networking, running /etc/init.d/network restart, but I must restart the computer to get network connectivity again. This does not happen every time I use the computer though, it will just randomly happen. Whats wrong?

It's hard to tell from what information you posted, but it sounds like a hardware issue. Either something is happening with the driver or some piece of hardware is randomly shutting off (this happened to me before with an old ethernet card.)

I would suggest that the next time this happens,

1. Try pinging something no more than 1 hop away (the router, another computer on the network). Also try pinging YOUR IP address.

2. Type in /sbin/ifconfig into the command line and check to see if your device is there (eth0?) with the UP flag on.

3. Copy the output of dmesg to a file (dmesg > systemlog.txt), reboot and post the contents of the file here.

Happy hunting
