Hey!

I have a TP Link WR1403ND v1. Due to a new internet provider (Unitymedia in Germany) I'm forced to use a "Unitymedia Horizon Box" as my modem and DHCP Server. I tried to connect them and I'm able to use the TP-Link WiFi with the Internet of the Horizon Box. However, as soon as I connect the Horizon Box to the TP Link, the TP Link goes missing (IP wise). This also happens if I use TP Link on its own. Example:

I factory reset TP Link, do not connect anything. I connect my laptop per LAN. I change the IP Address in the TP Link settings from 192.168.1.1 to 192.168.192.199. The TP link reboots but I cannot contact it again (neither under 192.168.1.1 nor under 192.168.192.199). Its just gone. If I do a factory reset I can find it again under 192.168.1.1.

Why do I do that?

Because my Horizon Box has a DHCP server I have to use. The DHCP server is set to start giving out IPs from 192.168.192.2 up to 192.168.192.66. If I "just" connect the TP link (IPsetup 192.168.1.1) to the Horizon I cannot access it again. It does not show up in the DHCP list of Horizon. If I change TP link to 192.168.192.199 before connecting it, i cannot find it too. In no way am I able to find the TP link, if I connect it to Horizon. However, it does work: He distributes internet over the WiFi. So... what now? It seems as if the router is not able to use another IP for some reason? Ideas?

Kind Regards
Constantin

I've gone almost mad today. I tried to set any other IP to the TP link than 192.168.1.1. It will always fail. The TP Link will not be reachable anymore until I do a factory reset and find it under 192.168.1.1 again. Why is that? I tried various IPs in 192.168.192.* ... can somebody please explain whats up?

What's the firmware version of your WR1043ND? Is it up to date?

What's your subnet mask? If it's 255.255.0.0, it's OK for you to set the IP pool of 1043 to range from 192.168.1.1 to 192.168.192.199.
However, if your subnet mask is 255.255.255.0, the setting goes wrong since the two IP segment belong to different network.

If you configure 1043 as an access point, the DHCP on it should be disable. If you set it as a router, you should configure IP pool to different network segment from the WAN IP.

PS: You can have a look at the system log to confirm whether the IP address is changed of the 1043. To help, please provide the topology of your scenario and the LAN IP of al the devices.
