Asus RT-AC1200G+ dropping streaming

Since I updated 3.0.0.4.382_51612 firmware I have noticed random key generation in syslog presumably this is an attempt to prevent Kr00K as noted in the firmware notes. But as soon as the random key is generated anything that is streaming stops. Is there any way to reduce the amount of keys generated in settings as it seems quite often at the moment?

I have contacted Asus through their Technical support and await a reply. This happens on both bands 2.4 and 5 depending which key is...
