This is really annoying. Every time I boot up my computer, my USB wireless adapter would seem like it's dead and not detected by the system. I would have to unplug it and plug it back in to make it work again. It work absolutely fine after that. But I would have to do it again if I restart my computer.
First I thought it was my wireless adapter's problem. Fortunately, I have other two wireless adapter lying around. So I tried them out, they ALL behave the same. So I'm pretty sure there isn't a problem in my adapters.
Anyone has any idea what's going on?
*i have also tried the power management to never let it sleep and max power settings. something like that. they don't work.*
check your mb vendor for bios updates to see if it a bios bug. on newer mb that have usb 3.0 chipset there are few settings check that your bios set to full on at post and full handoff at post. those setting may be turned off or set wrong.also try updating the mb chipset drivers could be a damaged driver.
