Couple days ago I decided to make an upgrade to my home network. Got my BT HomeHub DSL router flashed with OpenWRT 19.07, applied OpenVPN+Windscribe and Pi-hole (RPI W Zero) as my DNS blocker. Everything is working well, but the network speed dropped from 75 to 10Mbps.
I tried Wireguard - result pretty similar. I guess it's all to do with the slow router...
I've come up with some ideas, but I don't really know where to start:
I can use Windscribe's desktop client, and get regular speed, but DNS queries don't go through Pi-Hole. How can I force it to use Pi-hole?
If I will use Pi-hole as DHCP server, will I get the same problem as above?
Can I set wireguard VPN to work with Windscribe on Pi-hole and set router's traffic to go through Pi-hole?
