had this crash when restarting 5ghz wireless. Very bad performance and stability on a netgear r7800. Near wifi are on different channel, with old kernel 4.4 there were no issue. With the new kernel 4.9 i have this kind of problem and a bandwidth of max 20-30 mbps. Can make any test as for now i can't use it due to this problem. (Running lede with latest commit)
