Hello,

Upgraded to r46069.
did nvram reset and reboot

After some reboots, system seems stable but the speed seems to have gone down even after i set all config from previous setup.

What should i look into?

Thanks

that is the reason I asked what would you need from me, what info should I provide for someone to assist.

Following are the steps I used:
Connected laptop to router via cable
Opened up good ole IE
Logged on to dd-wrt, went to Admin->Factory Defaults
Selected Yes to Restore Factory Defaults
Hit Apply Settings

Then went to Admin->Firmware Upgrade and selected r46069 file

Then opened command window, Telnet to 192.168.1.1
ran nvram erase && reboot

after rebooting, set all previous config settings

Then, went to Admin -> Commands
Entered following
for CPUGOV in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor;
do [ -f $CPUGOV ] || continue;
echo -n ondemand > $CPUGOV;
done

Hit "Save Startup", reboot

Then, went again to Admin -> Commands
Entered
echo 35 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor

Hit "Save Startup", reboot

Thanks

2,4Ghz DD-WRT Firmware Mixed
2,4Ghz Vanilla Firmware NG-Mixed

5Ghz disable Multi User Beamforming

i would try the vanilla firmware..

do you have any iperf3 or speedtest measurements for comparison?

It certainly doesn't work that way.
Please set the scaling governor to performance before you complain about it.

Let me clarify that I'm not Technical and hence might not be aware of the whys of the steps I'm following. I just follow the steps I'm provided, sometimes not as well. Smile


I was just following the guide from
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=320614

Should I undo that? Is the following the correct way to do this?
Admin -> Commands
for CPUGOV in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor;
do [ -f $CPUGOV ] || continue;
echo -n performance > $CPUGOV;
done

Hit "Save Startup", reboot??

'after rebooting, set all previous config settings'

i hope you did restore your settings manually, aka copy/paste values

do not restore settings using save files from different builds....

-antenna gain i have 0 if im not wrong...
-Automatic Power save - must be set to disable
-i still use bacon interval 100 as 101 was causing troubles
-Sensitivity Range (ACK Timing) must be 500... I use 900, your value of 3150 is way too much..


for CPUFREQ in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do [ -f $CPUFREQ ] || continue; echo -n performance > $CPUFREQ; done

this script will max out its CPU....

In the previous r41813, I got better performance with Multi User Beamforming enabled when compared to disabled.

I can certainly try disabling and see once we confirm what to do with governor settings

Well, you could also leave out the scaling governor settings for now.
Performance is default
