Yesterday for the first time I installed openwrt build on my r7800 via tftpd64. Everything went smoothly, router restarts, I access luci, change wan to static ip, fill the info, enable two wifi radios, set name and password, download luci-app-sqm, but haven't set it up yet and that is about it. Done nothing more, the upload speed seems to take a hit compared to edgerouter that I have nearby, these are the test results.
Adjusting the cpu governor by ssh:
echo 35 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor
Did not increase the upload speed
edit: If I were to revert these changes, would physical reset button do the trick?
Those are run-time parameters for kernel, not stored anywhere as separate settings.
Simple reboot is enough to clear them.
(note that you need to set them again after each reboot. Or you could compile an own image with kernel patched with those values)
Also check you SQM settings that it really is disabled. First test qithout any SQM QoS tools, then start experimenting. (85/21 sounds really strangely low)
It scares me, because googling revealed that my cable might be faulty. Information so far - speeds are normal at edgerouter-x, RT-AC51U but bad with R7800.
Might need to reflash stock netgear firmware to rule out hardware error. Thanks for help
Thank you for linking the post, however even with stock firmware 1.0.2.63 the upload speed has yet to peak higher than 50 mb/s, where's on edgerouter it is reaching 85+ few seconds into the test.
The user has solved his problem with realtek driver, however I'am running windows10 packed with most recent drivers.
Cables - bought extra and tested both old and new, they are not damaged because testing out connection directly to poe injector gives 90/90 speed
Computer - brought over a laptop, wiring it to router - 90/20, wiring it directly to poe 90/90.
Router - bought C7 Archer1750 for 8 euro, installed 18.06.4 - 90/20
What setting could possibly limit the upload speed but not download, maybe I'am messing up the connection setup.
After installing the firmware, I navigate at interfaces, change wan(0.2) from DHCP to static addr, fill the fields, save, enable and configure wifi and that is it.
Problem solved: as I understand, without bandwith limiting, the browser based speed tests are not capable of measuring the speed due to some kind of reason. If I apply sqm while limiting my bandwith from 90/90 to 60/60 the speed tests do display upload speed normaly.
