Hi Jong
>I wouldn't recommend having the LAN and WAN side of the Draytek on the same subnet. Maybe it might work, but it could also cause some even more weird problems down the line.
Fine. I won't go with that then.
>It's very odd that setting the SH2 to 192.168.2.1 and letting the SH2 assign an address for the Draytek doesn't work. ???
It is, but a Virgin Tech agreed that 1.1, 2.1 up to 4.1 were reserved for the Guest SSIDs on this box. He suggested trying 5.1 but that doesn't work either. All give the error message and don't actually change the setting.
Anyway the Subnet Mask (which I have not changed) is 255.255.255.0 and only the last octet can be modified.
I have changed very little on the settings in the Shub2ac - just the DHCP Settings and tried enabling one of the Guest Networks to prove it really does allocate addresses in the 1.x range. And I have reset to Factory Settings twice to start again.
I think I am only left with two choices if I am going to use this box:-
1. Use Modem Mode and forget the nice dual-Wireless with 5GHz band.
2. Revert the box to Factory Defaults and IP 192.168.0.1 and change everything else on my network to 1.x.

Unless anyone can come up with another solution?

Or I could just abandon this new hub and revert to my old one which works fine in Router Mode with the new firewall! (I don't know about any issues with double NAT - would need to get more info on that. Perhaps someone can enlighten me?).
