A Note For Cable Broadband Users

If you can read this your cable internet access is probably working. However, just for future reference - it's not uncommon during thunderstorms for cable (Telstra and Optus) broadband users to lose internet access.

The problem is that if the connection breaks, even for a moment, before coming back up, both your ISP and your cable modem may still think you are connected, whereas the reality is that you're not. The ISP can ping your modem and get a response, so they believe you are connected and it's not their fault. They then get you to try to change all manner of settings on your computer (none of which work), and further complicate recovery.

If you are a cable broadband subscriber, and you lose your internet access and your ISP tells you there's no issue with the service, before you go any further follow these simple steps in order:

1) Turn off all computers, router and the cable modem. Unplug the cable modem from the power point.
2)
Wait 10 minutes.
3) Plug the cable modem back in and power it up.
Wait a couple of minutes.
4) Power up your router (if you have one).
5) Power up your computers and other network devices and try your browser now.

Unplugging the cable modem and waiting for 10 minutes causes the ISP's system to recognise that you've dropped off the network, so that when you log back in again your connection is reset and you're assigned a new IP address.

If you've still got connection issues after doing this, please speak to a Mac specialist like myself before trying anything drastic suggested by someone with no Mac experience!
