I have a home network with a router (dd-wrt firmware) connected to the internet that is also connected over a 200 Mbps powerline ethernet connection to another router (different make, also dd-wrt firmware). I disabled dhcp on the other router, which I'm using as an access point, so that all devices are on the same subnet.
When I connect over wifi to the router that's directly connected to the internet, I get 20 Mbps down and 6 up, which is around what I pay for. When I connect to the access point, I get < 1 megabit down and around 5 Mbps up. If I directly connect to the powerline ethernet, I get 20 down and 6 up. However, if I connect directly to one of the lan ports on the access point I get similar speeds to connecting directly to the powerline.
From here, it seems that either the broadcasted signal from the access point is faulty, or some underlying problem with dd-wrt on the access point is causing the problem. When I connect wirelessly to it, my laptop is 2 feet from the access point (and the laptop reports 100% connection). I have tried having the access point have a different SSID, as well as the same SSID. I followed this guide for the access point setup. I have tried both the "long" and "short" version but neither seemed to change much.
Has anyone else ran into similar issues with access points?
Main router: Asus RT-N10+ DD-WRT v24-sp2 (03/25/13) std
