Hi guys
I have read this topic and the topic on dd-wrt website, but i didn't undestand the best way to increase the rx :
- replace R17 for a 62ohm ?
- rotate the capacitors c93 and c94 ?
- or both ?
Thanks
ps : sorry for my language i'm french
Hi there,
I just finished the R17 mod for my WL500gP.
Noise level went down from -98 to -84
I simply soldered a 68 ohm SMD resistor parallel to R17:
Solder one side of the new resistor to the side of R17 that is closest to the shielding. Then solder a thin wire between the other sides of the two resistors.
See the attached image.
Pim.
By the way, the reason I used a 68 ohm resistor was because the local component store didn't have a 62 ohm.
I could choose between 56 and 68 ohm. The latter seemed safer.
Later, when I choose not to remove R17 (the led-free solder didn't melt with my low power soldering iron) I realized that 68 ohm is perfect.
A 62K ohm and a 68 ohm resistor in parallel together give (almost exactly) 62 ohm.

click on this link -> http://my.router/Main_AdmStatus_Content.asp
it will apear a secret page from your router's config webpage called System Command
in this window you will have to type the following command -> wl noise and click Refresh it will give you a negative value
if your result is something between -99 and -92 you have 62 K Ohm resistor installed
if your result is -89 or a higher value (eg -86) then you have the right resistor installed (62Ohm)

thanks..
I give -90 value.
I think have a right resistor installed but the measured noise value is not good. pre-amplifier not working correctly.
Hi all,
I have a WL 500GP with Oleg's firmware and the SN starts with 71 - that means a defective board. The wl noise command says : - 98dB before modding. After applying both condenser and R17 mod, wl noise: -98dB. Then, I have measured voltage at R17: 3.2 V at one end and 2.5 V at the other. Mesuring the R17 value I found a strange value : 3.6 kohm . Please tell me what to do to improve the noise value ?
Thanks for help!
