    Hi guys,

    I saw that "Regulatory Mode" option in Advanced->Wireless section of Victek's Tomato mod. It can be either OFF, 802.11d, or 802.11h.

    I couldn't find explanations about it in Tomato's wiki. From what I've read about 802.11h I understood that it deals with interference (according to wikipedia). The 802.11d, as I've figured, apparently adds country code to every beacon.

    Is the above info correct?

    And also what is the best/proper setting for that option? The default is "off." I live in the US now and my router is wrt54gl v1.1 if that info matters to the subject.

    Thank you beforehand!

    Reading through that thread. Seems like it is best by leaving it at default to Off.

    Correct. It has no useful function as far as we are concerned. However, if left "floating" in an unknown state, it caused association problems. However, just in case it ever needs to be changed for some reason we don't know about (yet) "Teddy Bear" decided to add the choice box, defaulted to "off".

    I read on other forums that some have significantly better results with regulatory mode set to "h". Supposedly there should be less interference when the spectrum management (utilized in "h" mode) is used. OTOH it can cause connectivity problems with some clients. "Off" seems to be the least problematic setting overall - but you can also try "h" or even "d" to see if that works better for you.

    Thanks a lot, guys! I'll try with 802.11h and compare.

    Ok, finally, after a couple of days of testing i have some results. Two of my older laptops with 802.11b loose connectivity with 802.11h regulatory mode. For my other 802.11g devices setting regulatory mode to 802.11h didn't change anything noticeably. I didn't use 802.11d for testing.
