Thanks Virgin!!!

[Rick Anthony]

Spent ages setting up my workgroup network last year using my Virgin Superhub 2
Private DHCP range - Fixed IP for printer and NAS - assigned IPs for wireless devices
This week a fault at the local exchange basically fried several modems in the area and we got Superhub 3 as replacements because they could not get the SH2 to initialise for some readon.
So I come to set up router
Very limited access to DHCPv4 cannot retain my IP range or connect to either NAS (over 2.2TB of data on each)
Basically every device will have to be accessed and reconfigured all over again.
What makes it even worse is I has been unemployed since just before xmas so until I find a new job or get benefit I cannot buy a 2nd router and reconfiqure that.
Oh well got a PC to build - best finish that and then sort this mess out - Rant Over

At least you have the time to do the reconfiguration?

Often you can get more control over ISP devices by using a terminal session, but I don't know with this specific model.

The best advice I can give you is move away from relying on your ISPs kit to do anything more than provide connectivity. Get your NAS running ISC dhcpd or similar and disable it on the router. I've gone to a virtual machine and software router, it's far easier to keep configured and secure. The device between my NIC and the wall is acting purely as a modem.
