Had a read through the forums but cant find anything regarding settings for a wireless AP through a TC 5101 cable modem. I have a Zyxel B3000 access point spare that I want to set up for a mate who has TC cable. Anyone know if the TC cable modems are usually set to DHCP so that I can get the B3000 to get its IP from the modem? I tried but it didnt seem to connect?

They are modems only. You'll have to add a router and enter TCL public IP address etc. into WAN interface settings.

Spark Max Fibre using Mikrotik CCR1009-8G-1S-1S+, CRS125-24G-1S, Unifi UAP, U6-Pro, UAP-AC-M-Pro, Apple TV 4K (2022), Apple TV 4K (2017), iPad Air 1st gen, iPad Air 4th gen, iPhone 13, SkyNZ3151 (the white box). If it doesn't move then it's data cabled.

To amplify this... If the modems are offline (press the little button on the top), then they DO act as a DHCP server---but only for the 192.168.1.x range. They do that so that a local LAN can operate if the cable network is unavailable.

However, when online, the modems are pure passthru. Furthermore, cable currently has static IP addressing, with no DHCP, so you have to configure the address, mask, DNS etc, as Spyware said.

Now, although the modems are strictly layer-2 devices, they do have a bit of a split personality, in that they filter IP (the filters are set by the carrier and are not anything the user can touch or see) and they respond to the address 192.168.100.1 (you can access their internal web server at http://192.168.100.1). Nevertheless, as far as your traffic is concerned, they are strictly layer-2 devices and in no way function as a layer-3 gateway.

Right thanks for that, explains why nothing would work. So I guess I need to look at a device recommended in the other forum posts, or possibly just get TC to supply a wireless solution.
