I am new with this beautiful openwrt system and i just installed the system on BT hub 5 on it but in my home i have normal talktalk latest wifi hub 2019 as my main broadband ( no openwrt on it )
.and i was looking to make that BT Hub 5 ( have openwrt on it ) as main router connecting to the talktalk as wifi extender using powerline adapter
The "LEDE Installation Guide for BT Home Hub 5A" has ISP specific configuration examples for multiple ISPs, it's mostly a question of selecting the correct VLAN tagging for your ISP.
Well, technically you want to use the TalkTalk as AP. Range extenders typically connect to the network witlessly, while in your case you will effectively interconnect the routers by LAN. There are different types of power-line kits, but a basic kit of 2 with 2 routers, it would be as if you are connecting bother routers by an Ethernet cable.
I don't know how far apart the 2 routers. For a small apartment, you could in theory connect the router wirelessly, but that's subject to firmware, chip sets and drivers etc. So it's probably easier to just use the powerline thing, but I am just mentioning the other option if you want to try it first. A factor would also would be weather you care if the clients of the "extender" are on a different subnet or not.
Note that for Powerline kits, some have devices with built-in AP function (so you could just get rid of the TalkTalk router if you have no other reason for using it. It's worth looking at what's available in the market and check your budget.
Before i buy bt hub 5 with preinstalled openwrt on it
I used to have talktalk broadband with two routers connecting using pwerline or tplink adapter and all i jave to do was disabled the DHCP in the second router
Now i am still have the talktalk broadband and i want to use the BT Hub 5 as the main or first router which have openwrt installed already then tplink connecting to second normal talktalk that have no openwrt on it and disable the DHCP like ibused to have before
Or its different and process is different
Thanks guys i wrote a lot juat to make you understand my problems
No, BT Smart Hub is aka Home Hub 6, which is not supported by OpenWrt as of now.
And to add more confusion, contrary to Home Hub 5, where Type A was Lantiq/QC/Ath and Type B was Broadcom, Smart Hub Type A is Broadcom and Type B is QC!
If you have them already, just hook them up and it should work. Consider them a long Ethernet cable. If you have the two routers set up properly, you should have no problem.
I imagine you would want to connect the powerline units to the LAN port of both routers.
Like you said, you will only need to disable DHCP on the client router, connect powerline to main router's LAN, and connect the other runit to client router's LAN.
Ah, and it goes without saying that you would want the client router to have static LAN IP address on the the same network as main router (for example, give it IP 192.168.1.2 if your main router is 192.168.1.1), and make sure that the DHCP server pool on the the main router doesn't include that IP address. Default for OpenWrt is from x.x.x.100 to x.x.x.249, so it should be fine.
