    I appreciate that this page might not have been updated for sometime, capabilities shows (IMHO) info not too... readable if that's the word, where rates no matter what it always displays:
    btw what is the meaning of green and blue font in the rate column?
    I haven't tested a wireless b AP, but I would update the rates up to 150/300/450 when available or alternatively remove the column

    my 2 cents

    The lines indicate what protocols and data rates are supported/advertised by that router. Because multiple data rates/protocols are supported (802.11b, 802.11g, 802.11n, etc.), there can be multiple lines. On a per-protocol basis you can also limit what speeds/capabilities are advertised (such as disabling support for 11mbit on 802.11b, or similar methods for other protocols). I believe the colour difference is just to indicate different protocols.

    The first (blue) line -- example you gave: 1, 2, 5.5, 11 -- indicates 802.11b support. The 2nd (green) line -- see reference picture -- indicates 802.11g support. I believe 802.11a and 802.11n show different colours as well, but what they are I don't know. You can look in the source code to figure all of this out I'm sure.

    See Wikipedia for details on different rates/protocols.

    Your proposal on what to change doesn't make any sense -- too vague/ambiguous and not enough reference data (screenshots please). I'm not disagreeing with the idea that something could be changed, but what you've stated is strange/doesn't make any sense at this point.

    The data I see in in the Wireless Survey makes absolute perfect sense to me.

    Tomato doesn't always display the same thing, only looks that way because most routers happen to support the same speeds. Here we have public ISP access points that have fewer available speeds and Tomato correctly indicates that.

    Having Tomato indicate "N" speeds would be nice, I agree.

    As far as I can see, rates up to 11 only indicates a wireless B, rates up to 54 a wireless G, 20MHz under the channel is wireless N150 where 40MHz under channel means wireless N300.

    I don't have wireless A so I can't verify

    About N300 it displays only the primary channel but not the secondary.

    Don't get me wrong I'm not complaining! I'm just thinking that perhaps replacing the capabilities column (does anybody look at this column at all?!) with B/G/N150/N300 and add the secondary channel on N300 would be a step forward for that page. Unless somebody else has a better idea.
