I would say that ... with a Quickertek 500mw amplifier connected to a wireless card in my laptop than the Buffalo HP with its transmit turned up... I can see far more networks this way too from the laptop than the Buffalo site survey, so I think the Quickertek is better at both receiving and transmitting.


Try:

nvram set boardflags=0x3758
nvram commit
reboot

keeps the amp on and turns on the enhanced receive sensitivity of the Broadcom 'E/EL'-series 'Broadrange' chipset. I see a +10 SNR because of this setting, using my radio in client mode. The WHR-G125 I believe also has this broadrange tech, but no amp, so 0x1758 should work for it. The low sensitivity you are getting is because only the amp is on.

Just to say thank you!

I hope that you don't mind but I've updated the wiki page for this router with the basics of this information and a pointer to this thread.

Now the remaining open question: At what point does the increasing power actually start hurting data throughput due to peak limiting in the amplifier.

I can't seem to navigate this 'new' (many months old now) Wiki main page. The search function works okay.

Can you post a link to the updated page? That would help a bunch.

Thanks for the reading. That bountiful router suggested by larryrn really is a cool peace of kit ..... only if DD-WRT was available for that .... Wink

"The Most Powerful Wireless Router Allowed by Law. For five years Bountiful WiFi has pioneered superior wireless technology."

Reaching The Outer Limits of 802.11b/g

Nearly 30 dBm, the limit specified by current FCC Regulations.

4X the range, up to a quarter mile of WiFi!

Extreme receive sensitivity of -95 dBm, even weak clients can be heard.

any results for the v24 firmware? I'm kinda leery about adjusting tx power without this info, especially considering how hard these are to get locally now.

I didn't understand that, how can we get 722mW for opening amp and making boardflags=0x3758? Is that enough? and should we use heatsink or not? If we should which chipsets?

For good reason. That is not how you do it.

It's a little early in the day for him.
GeeTek give me some power outputs guesses for the Asus WL-520 GU before you drink the worm.
