Netgear a6100 wont connect but the other wireless WIFI adapter I have will

Just a few days ago i was using my wireless adapter cimpletely fine and i did not mess with any of the settings or anything involving it. Than all of the sudden one day the thing just stopped working. I had installed the software and it worked fine again for about an hour than the thing just stopped working again it makes no sense to me. Yet my other wifi adapter still manages to work completely fine. Also awhile ago the a6100 adapter was also having a problem with disconnecting for NO reason. i just dont understand why it has so many problems. Also i have tried all of the suggestions to fix it off of the website and i have looked at multiple other posts to also try and find a solution. Nothing seems to work for me.
