Asus wl-520gu - possible to flash non-ND firmware??

    As the title says, do the non-ND tomato firmware work with the Asus wl-520gu router? The reason I would like to use the non-ND firmware is that I want to increase my transmit power up to 150mW but I have to use channel 11 (which is the only reliable channel that works in my house for my devices. It seems that with the ND-driver firmware, that using channel 11, I cannot increase the power very much but I read this is the fault of the ND driver firmware itself.

    Also, I was trying to find (without any luck) the post by Toastman where he did and listed his extensive tests using the ND and non-ND firmware along with changing the country code and came up with a complete summary of the effects of these different combinations. Can someone point me to it?

    I'm not aware of this issue or the specific thread you referred to. But perhaps it's one of the links that Toastman recently posted here.

    There is no specific problem with recent versions of software in setting 150mW on channel 11 - at least on the WRT54GL series.

    However, the SOC chipset used in the ASUS WL520GU has the wireless chip onboard and is not so conducive to having it's configuration changed. I do remember having experienced some odd effects last year when I was testing my WL-500GP v2's, and I just stopped trying to conduct any serious experiments on them. Maybe someone else could post their own experiences with the ASUS machines?

    Oh, I could have sworn there were posts by you about tests you ran where with the ND-drivers there was only full power available for channels 1-8, and also differences in max power depending on the country setting, etc. When and how did they fix this problem and I thought you said it was a limitation with the ND-drivers?

    Do you have a link to this post and tests by you that I am referring to?

    There was indeed such a post in which I did a lot of tests, and I've just quickly looked for it, but can't find it. I do recall the tests in which the power below channel 8 was lower, I don't have a local copy here now. I remember that it was at the time also checked by Victek, who found the same thing. But it's no longer happening. You can very easily check it, though, set 251 as the maximum, just swap channels and compare the results. The wireless drivers will then override the setting with whatever default it uses and you can compare the results easily by changing channel. For channels 1-11 use the US setting. If you want 1-13 set Singapore (SG).

    But none of this may be relevant to your ASUS router. It believe it did not behave in the same way.

    I just checked myself right now. With 1.27 ND, power to 150, compared with 1.27 non-ND, power to 150, there is a 10 dB difference in RSSI according to Inssider with the non-ND driver being the stronger signal.

    Again, though, the original question, does the non-ND firmware work with the Asus router mentioned?

    Is there a "ND for dummies and/or new-to-forum-folks" that I can reference?

    I (all-be it quickly) looked over the stickies and didn't see anything that breaks out the who/what/where/when/why behind the ND... though I do see it mentioned all the time.

    I get the basics, its a new wl0 driver that depending on the output of "nvram get wl0_corerev" you can run one, the other, or both. But is there an expanded description?

    Also, is this the same as the ND2 I see mentioned a lot on DD-WRT forums? I'm guessing it's a extension beyond the original ND, but I just don't know for sure.

    No, non-ND firmware bricks WL-520GU. Well, it doesn't completely brick it, as it's very easy to restore thanks to the Asus restoration utility... But it doesn't work.
