recently ran Ethernet cable out of back of my windstream router/modem to another router that i made an access point. plugging said ethernet cable directly into computer i am getting speeds up to 12-13mbps which is what i pay for. so seems that ethernet cable length doesnt seem to be an issue. but as soon as i plug into a wireless router turned to ap my speed wireless and wired are not even .5mbps. I have changed channel on ap trying each channel also i have tried another router turning it into ap as well.. please help me understand by i can get 12-13mbps plugged directly in and ap slows internet download speed
