What ethernet speed can be achieved with Omega2 LTE and Ethernet extension board?
-
Hi,
I have Omega2 LTE board (Omega2S+ on it) and ethernet extension board but I have problem with data rate.
I can not achieve more than 16.8Mbps so I am wondering if it is something that can be resolved in software or there is a hardware limitation?
Did anyone manage to achieve higher data rate? I need at least 40-50Mbps for my application.Thanks!

@grbaxtz How are you testing?

First, we made WiFi to ETH demo so we can connect PC with ETH port to WiFi and speed test showed 16.8Mbps (2.1MB/s).
Then, we tried scp big_file root@192.168.100.1:/dev/null to eliminate WiFi as bottleneck and we got the same numbers.

@grbaxtz what does iperf report?

Just for reference, testing my Omega2S based boards with ethernet and iperf3 against a iperf3 server in the local network gives me ~95Mbit:

mt76on the other hand is probably a lot better now than it was in 19.xx.

@luz my testing on OpenWrt 21 some time ago gave similar results, 90ish Mb/s depending on what services are running on the Omega2 at the time. My comments were an attempt to encourage the author to undertake a recognised testing methodology and report the results
