I am now on the SKY router! Just changed IP address, LAN restrictions and wifi names and passwords to the Orcon ones and everything just works!
The only thing that hiccupped was the mappings to the NAS with user or password error. I did another mapping and its user/password entry made all the other mappings come right.
Only thing now on the Orcon router is the landline. The SKY phone connection is from the ONT. Just have to hope it has been ported!
Now just wait to have Orcon kill my link today and SKY to connect me tomorrow.
Once again, thanks for help.
