BT HomeHub 5 resetting itself

The last time it caught me out, but this time I was more prepared.

A brief power cut meant the HH5 rebooted. And with it, all internet connections lost for devices with static IPs.

And why's that? Because the process of rebooting causes the router to reset! So SSID is changed, and the gateway IP is set to 192.168.1.254 (from the 192.168.2.x range)

At least this time I knew what to do:

  • Go into Network Preferences on Mac. 
  • Change Ethernet connection so IP address is in 192.168.1.x range
  • Change router IP to 192.168.1.254
  • Go into router settings (from 192.168.1.254 now)
  • Amend SSID back to what it should be - save
  • Amend Hub IP Gateway address to 192.168.2.x range - save
  • Amend the DHCP range too
Then...

all (all!!) that's left is to rename the devices in the Home Network table (as they all get lost too) and then reset Access Control to avoid unfettered access. Half an hour or so of work that shouldn't be necessary
