What is it about DSL and Cable routers that cause them to stop working until you reboot them?
We have an 18 month old firewall device at the office that has been acting the same way for the past ... 18 months.
I've discovered a solution - well, actually a work-around. Turning the router off/on once a day seems to solve the problem.
Here is what you do to automate the process:
1] Go to IKEA or Walmart and buy a $2.50 lamp timer.
2] Set it to be on except for a period of time when you never use the internet, say 3:00 to 3:30 AM.
3] Plug it in.
4] Plug your router into the timer.
