Hey everybody,

What is the exact number you’re getting for the upload test? Is is 100Mbps exactly? Higher? Lower?

And how are you testing it? Wired? Wireless? On the router itself? With what tools?

ckatsanis · May 13, 2023, 8:38pm

Hey, i m tested wired with speedtest. Before installation i have 8ms 950~down 950~up
Wireless i have above 60mbps

lleachii · May 13, 2023, 8:41pm

Did you enable Flow Offloading?

psherman · May 13, 2023, 8:44pm

I am having trouble understanding the speedtest results -- you've got 500+ Mbps results and 65-85 Mbps... what does each entry represent?

shdf · May 13, 2023, 8:45pm

these lines are missing in his firewall config file, so he didn't enabled HW offloading

option flow_offloading '1'
option flow_offloading_hw '1'

ckatsanis · May 13, 2023, 8:47pm

that i means

i m try the flow offloading now

psherman · May 13, 2023, 8:51pm

This isn't really clarifying the results you showed before...
There was large variability from run to run in your earlier response. Were all of these tested with the same method (i.e. wired to the same router with the same settings for every run), or were things different on each run?

ckatsanis · May 13, 2023, 8:51pm

This was fixed this issue thank you very much!

ckatsanis · May 13, 2023, 8:52pm

the same settings without offloading but i see with offloading on runs fast

ckatsanis · May 20, 2023, 2:36pm

Hey again.

I m tested about 2-3 days i see that the download speed after 10 hours was decreased to 2 mbs and upload still to 100-300 over wifi and Eth.

If device rebooted all working fine.

Any idea what's wrong with that? This was and before openwrt installed.

Thank to all for helping!
