Connected two TL-WA865RE (not TL-WA860RE - this was the closest option in the drop down menu) wifi extenders for better range. Now laptops, gaming consoles, no longer receive internet from the original network, even when right next to the router. The devices will show up as connected to the original network, but no internet will be available. Now have to connect to the extended network from all parts in the house, even where the strength is barely there. This has actually significantly worsened the wifi connection in the house. Problem isn't present for phones or tablets.

I have disconnected one repeater but this has had no effect so far. I found two other locked threads from people with a similar problem but their issue never seemed to get resolved, so clearly this is a recurring problem with TP-link repeaters.
