Linksys WRT32x Wifi Signal Power


I have Linksys WRT32x router and I am asking if it possible to reduce the WiFi signal power in that router throw radio configuration file which locate in this path /etc/config/wireless or in another file maybe ?

Sure, have a look at txpower:

Hi sumo,
thanks for reply

There is no such as parameter in wireless file as you can see in below

Well, you could just add whatever option you like.

If by stock firmware you mean the vendor one then you would need to ask via their support. This forum is about true upstream OpenWrt.

If I remember correctly, the WiFi chip of this model does not allow signal power adjustment. You cannot increase or decrease it.


I added that parameter just to try but it does not solve the issue it seems to be there is another file have control on this thing
I asked here because WRT32x router operate by OpenWRT firmware so I thought I can find someone here can help me with this

Hi LGA1150,
Thanks for reply

I can reduce the WiFi signal power by installing dd-wrt firmware so I think the chip of this devices allow to do such as this thing on stock firmware but I don't know how

Doubtful, as dd-wrt uses mwlwifi, same as OpenWrt. The venom power table is fixed at maximum, as read from eeprom as indicated by output of:

cat /sys/kernel/debug/ieee80211/phy0/mwlwifi/info
power table loaded from dts: no

this from a rango.

Hi Kabuli Chana,
Thanks for replay

I installed Openwrt firmware and try to reduce the power but I didn't succeed with that
The only way makes me do that is by install dd-wrt firmware however in your opinion can I do some change on power table in eeprom ?
