The easiest way would be to use flow offloading on ath79 instead IMHO.
I tried that but the wireless speeds are not more than 200MBPS on 11ac radio and GbE wan
Wireless speeds are not related with offload type.
so how to increase wireless speeds as I have a really powerful device 4x4 11ac device but the wireless speeds are no where close to be accurate
You can open a new thread, because it's off-topic here. Most likely you speeds are not as expected, because the client devices are not 4x4
Could you please tell how to port to 18.06.2 for WDR4300 v1?
The advantage of 18.06.2 is that all of the drivers are new....
