Hope you can help. I've had my TD-W8970 running as my prime router for a few years now and its been running fine and far more reliable than the router that my provider sent me. However, its time to upgrade! So I'm turning it into a wifi extender.
I've followed the handy documentation here: https://openwrt.org/docs/guide-user/network/wifi/relay_configuration
but when I get to the important part - creating a new interface for the repeater !! as shown in this screen shot from the documentation...
on my version of the page there is no option for Protocol Relay Bridge!
I've continued with the instructions - and it does perform as a Wi-fi extender - but the network is very slow - like 10% performance of the original network speed.
Any help would be very much appreciated to breathe a new lease of life into the router!
