I used DWA-182 in 3 PCs with Gigabytes motherboard and USB3. It reports "The Device can perform faster if you connect it to USB3 port". Every time when the PC is boosted, DWA-182 will connected and then disconnected for 2 times before it can have a 5GHz connection. Sometime after 2 connected and disconnected, it remains disconnected. What I need to do is to unplug and plug the DWA-182 again. Very annoying as compared with DWA-140 (which is 802.11n), which is very reliable and stable.
My firmware of DWA-182 is v.301B. Windows 7 Ultimate, 64bit. Wifi router is DIR-868L.
Any suggestion and help is welcome.
