Thanks for the replies, unfortunately I still don't seem to be able to configure the device to just the way I want it.

In Advanced Config/Lan IP configuration it does allow me to change the IP address to 172.22.57.1 and the subnet mask to be 255.255.255.128 but as soon as I hit apply it gives me the DHCP error. It won't let me change the DHCP allocation range (I want it to run 172.22.57.30 - 59 with a /25 mask) but the only thing it seems to let me change is the last octet for the DHCP range.

I did think that based on every other router I've configured which had a similar situation, if I disabled DHCP, then applied changes, then change the LAN IP address and apply changes again, it would then change the DHCP range to be on the new subnet. But even with DHCP apparently disabled as soon as I try to change the LAN address, I get the same error message about it not being in the same subnet as the DHCP server (what DHCP server, I've just disabled it!!!!).

Anyhow, I'm running it with my exisiting Linksys router in the DMZ and passing all traffic to it. It's all working fine, download speed is stable at about 47 Mb/s which is fair enough, upload speed is still pathetic but my area hasn't had the uplift yet. So really I should leave it all alone but I really wanted to reduce the number of devices had and also give the SH the benefit of the doubt, what with all of the threads complaining about it's performance and see if it really is as bad as some people have said.
