I purchased archer t3u cause my pc is not supporting a 5Ghz connection. I can connect 5ghz with the device now but every one hour it's turned off sometimes comeback after a few seconds, sometimes doesn't come back until I plug it out then plug it in again. Once it's turned on again when I try to connect 5Ghz it shut down again. I wait till' device turns on again with the auto connection I can connect 5Ghz. But when I tried to connect 2.4Ghz I can connect perfectly. 


 How can I solve this problem? I am using the latest software for the device.
