Network Stops Working

[coastertux]

After not using my computer for a few hours, the internet stops working. If I try renewing my IP, it still doesn't work but if I shut down and reboot, it works. What is wrong? I connect through a wired network and a cable modem.

do you have a router or just pluged strate in to the cable modem?

 

[coastertux]

I have a router. It never did this before. It just started recently!

check you cables, also power cycle the router....

 

[coastertux]

I've done that already.

Try setting your cable modem IP to static if possible. Seems to me like a DHCP issue. What's your modem. Ask the ISP if they did any tftp-ing on your MAC recently(i.e. updates, downdates of the FW). What's cable modem's interface - USB or Ethernet?

 

[coastertux]

Cable modem's interface is ethernet.

reset the routers firmware to defaults....
