my network looks like this:
PC1 <–ethernet–> SoHo router <–ethernet–> GROOVE CPE <--------5GHz-only-N-------> RB433 AP <–ethernet–> SoHo router <–ethernet–> PC2
When I download something from PC1 to PC2 I get 7.5 MB/s datarate.
When I upload something from PC2 to PC1 I get only 2.5 MB/s datarate. Why?
Wireless setup of AP and CPE is ok, it gives 135/135 Tx/Rx rate, 99% CCQ and ROS bandwidth test confirms it. There are no queues or other kind of bandwidth limitation.
Shall I replace the SoHo routers to make sure that no faulty hardware is causing the upload/download discrepancy? Shall I check the ethernet cables? Or is this software related?
