Model: TL-WR902AC  
Hardware Version: V4
Firmware Version: 0.9.1 0.3 v0089.0 Build 230506 Rel.55329n(4555

Can you explain why i cannot change the DHCP address range from 192.168.0.xx to another range, e.g. 192.168.10.x.    Surely this should be allowed !  or even a 10.x.x.x range ?

As @SergejKiller posted, you should first set the router LAN IP address within the desired subnet and then set the DHCP IP address pool.

That is because router LAN IP address should correspond (be within the same subnet) as the DHCP Server IP address pool.

  @RichStaf, You have to do this from LAN settings page, not from DHCP.

I also have a problem with DHCP server. I do not understand the limitation that "Address Reservation" IPs should be inside the DHCP allocation pool.

In other words I have DHCP range from 192.168.0.100 - 192.168.0.200 and I cannot add address reservatoin with IP 192.168.0.10. This restriction is annoying and totally unnessesary.

I believe the logic behind this is that address reservation make sense only when devices receive their IP address by DHCP.

Outside DHCP Server IP address pool you can set a static IP addresses for client devices.

There's also IP&MAC binding ARP anti-spoofing mechanism to bind an IP address to a particular MAC address that you can use for these.

If Smart DHCP is used then the wifi devices reccive addresses from the WAN adrdress range because the WAN DHCP sevrer provides them. That's fine.... Howevere I want my WAN DHCP server to provide a fixed IP address from the WAN range to the WAN interface based on the MAC address of TP-LInk (That's done in the WAN router). Fine. But I then want to provide a completely different IP address range to all wifi clients using TP-Link from the DHCP server configrured within the TP-link. Is this easily configured ?

If I understood correctly you need a different DNS server on the LAN side of the TP-Link router. If that's correct you can do that here:

  @terziyski    Thanks for the tip, but I don't have problems with DNS.   My problem is configuring the DHCP addresses for the LAN Wifi users.

  @RichStaf Maybe I should explain again.  The WR902AC will only be used for wifi clients.   I want the wifi clients to have their own subnet and these addresses to be given out by the DHCP server configured on the WR902AC itself.    The WAN IP address of the WR902AC will be a different IP address obtained from the DHCP server on the WAN network.  In other words, the WR902AC would perform NAT.  What is the best way to configure this ?

WR902AC does NAT in two of its working modes - router mode and hotspot mode (WISP mode).

Depending on how you connected it to your main router (wired or wireless) choose WR902AC mode accordingly.
