Having weird problem. Flash player keeps crashing and freezing when using 5ghz but not 2.4ghz

I'm running 64bit windows 7 and windows 10 but this is happening on windows 10. Basically whenever i try to view flash videos under 5ghz wifi they freeze or just skip to the end and never plays.Under 2.4ghz wifi it works fine. This happens in Chrome and firefox which are running the newest flash player.version 20,0,0,286. This doesn't occur when I use the older flash players on internet explorer(20,0,0,272) or Microsoft edge. This problem doesn't seem to occur at all when using windows 7.I'm running the newest drivers on my broadcom wireless pcie card and windows 10 is up to date.Chrome and firefox are also up to date. Both browsers are 32bit.
