Good day!
// Are you using the latest drivers for the adapter from D-Links web site?
Yes.
// Ensure the default (dlink) SSID name is changed. Ensure that different SSID names are used between each WiFi 2.4/5Ghz radios. Can be anything and not
// something that's already in use by any neighbouring WiFi routers. Under Setup/Wireless/Manual.
Done.
// What wireless modes are you using?
WPA2, 20/40, auto channel. Maybe you mean somthing else?
// Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?
Yes i have Mac Book AIR and Samsung galaxy note3 on my 5 Ghz and two computers and xbox360 on 2.4 Ghz. Its work fine. One of computer with DWA-131.
If i take DWA-131 in my computer its also work fine. Problem just with DWA-160. All other devices work perfectly.
// Any other WiFi routers in the area that maybe causing interferences? Link> Use InSSIDer to find out. How many? Use v3, its free.
Its 4 routers on 2.4 Ghz and no one except my on 5 Ghz.
// Test the adapter on a different WiFi AP source, say at a friend or families place to see if it still happens.
Test my DWA-160 on Dlink DIR 300 AP with my computer. Its the same problem there.
Thank you.
