Tool/software: Linux
Hi ,
We tested the Wilink8's throughput TCP TX is very low with SDK4 kernel 4.9 on AM335/AM437x EVM.
The throughput TCP TX with 2.4G & 5G around 2X Mbps , but TCP RX & UDP TX/RX are normal.
Does anyone have any ideas?
The Test Data as below,
WiFi AP Router : Netgear Nighthawk x6 R8000 AC3200 (security.: Non-security)
2.4G Channel : 3
5G Channel : 36
Platform : AM335 / AM437x
Kernel : 4.9
WiFi Firmware : Rev 8.9.0.0.76
iperf command:
TX : iperf -c xxx.xxx.xxx.xxx -w256k -l16k -i -t60
RX : iperf -s -w256k -l16k -i1 -t60
