Extender gives low speeds
Hi wifi has been patchy at the back of my house. I have Ethernet in the kitchen at the back. I bought a TP link and plugged it in. It can do 300mbps. The hub 3 admin page listed the Ethernet connection as 100. My iPhone gives me about 15mbps and my older iPad strangely gives about 35. None of these are anywhere near 100. I don’t seem to have any way to modify or specify the Ethernet speed on the hub admin page. what am I doing wrong here please?
