Resetting Your Internet Connection
If you use either DSL or a Cable Modem and find your Internet connection has unexpectedly gone down, before you dial up tech support, try “resetting” your Internet connection. Here is how:
1. Shut down your computer.
2. If you have a router, unplug it.
3. Unplug your DSL / Cable Modem.
4. Wait 30 seconds.
5. Plug your DSL / Cable Modem back in.
6. Wait 30 seconds.
7. If you have a router, plug it back in.
8. Turn on your computer.
For the most part, this will fix any connections where your Internet connection has all of a sudden gone down without you having reconfigured your environment. However, if your ISP is having issues at the time, this will not fix it (as it is up to them), but it is a good starting point for troubleshooting.
