Builds for Linksys WHW03 V2 + V1

Okay, I've done some speed tests with iperf3 and I'm encountering performance problems. Let me explain.

Router WRT1900ACS iperf3 -s

Velop connected in 5GHz via QCA9886
iperf3 -c wrt1900acs :

And with the pc wired to the Velop :

iperf Done.

Performance halved
Do you have the same results?

PS: With the option enabled in the firewall Software flow offloading, speed rate rises to 195Mb/s
PS2: Velop (iperf3 -s) (eth0) -> PC (lan) : speed 902 Mbits/sec
