I'm working on a wireless network with a wireless router and 3 access points. All are D-Link products. Everything works well except near one AP. Most laptops work well with it, but 2 will not. They receive a strong signal but are very slow to load a web page. If you move closer to another AP, they speed up. I can have 2 laptops side by side and one will be fast & the other slow. I reset the AP and input the static settings, with the same SSID, encryption, passphrase, and the channel of the weakest other AP (18%). I think there may have been a voltage surge on the system because the last time I worked with it, I set the channels at 1, 6, 11 and 1. Today there were 3 AP's with channel 6 & the weird one had switched to dynamic LAN. Now it is set properly but still is slow on certain laptops. Any ideas on how to proceed?
