We have two Windows 7 laptops that connect through an older Belkin ADSL modem / wifi router. We have a second Siemens wifi router on the network that acts as an extender.
Frequently, when the router happens to restart (typically because a child-initiated-power-cycle) the wireless network will reappear, but with a '2' appended to the ssid.
After that we don't seem to be able to get a connection to the outside world, either after disconnecting and reconnecting or powercycling the router again. Only a laptop reboot seems to fix things.
I can't seem to hit on the right question to ask the internet, so any suggestions gratefully received even if not the actual answer.
