I'm relaying an excerpt from off forum site contact regarding this problem:
"I received an email from D-link today saying that 192.168.7.X can't be used, because the Dir-645 uses it for it's guest zone function.
Here's my reply to them:
"You sent me an email today stating that the 192.168.7.0 range can not be used because it is already used for the DIR-645 guest zone function. In the same mail I'm asked if I can't change my subnet!
The answer is already in my initial email. There's a dental practice software package installed on 3 PC's which are connected to the database via the fixed ip-address (192.168.7.14). This connection can only be changed when knowing the software manufacturer's password. It would cost me money to have them change the connections to the database!
This is perhaps not a bug, but certainly a DESIGN FLAW or wrong reasoning by the firmware developer. The firmware should be made in such a way that it chooses a free available subnet other then the subnet chosen by the network administrator and not the other way around!
I'm hoping this will be fixed soon in a new firmware version!
Hoping to hear from D-link soon!"

Hi Furry,
I tried activating the guest zone on the DIR-645 and connected to it wirelessly. And indeed, I got an ip-adress in the 192.168.7.X range.
I don't really care if getting the software manufacturer to change the connections would cost a lot or not. It has become a matter of principle to me now! (My network is up and running, remember?) As a customer I may expect to buy a router, change it's ip-address to what I need and be able to use it.
How difficult can it be to program the firmware in such a way that if a customer needs to use the 192.168.7.1 subnet, the firmware will pick an other ip-range?
The help-desk operator I phoned today, was completely on my side. He did not understand that there was nothing in his books/manuals about this and was annoyed that this reply had to come all the way from Taiwan! No body of his colleagues In Europe knew about this. And apparently the USA help-desk doesn't now yet either!
The help-desk guy agreed with me that the error message we got was not clear enough and he agreed that my proposed firmware change sounds very logical indeed.
I'll see what happens next. If the firmware developers are as quick as the forums activation email support team, I'm afraid I'll have to wait for a little while longer! ;-)
Perhaps it would be interesting if you could connect to the guest zone of one of your other routers, see what ip-adress you get and then try to change the router to that ip-address-range. I'm curious to know if that would work.
Your help has been great, the helpdesk guy here in Belgium has been very helpful as well. Now I'm curious to see what will come out of this?
Brgds,
Koen"
