    Hi I noticed today that none of my wireless laptops, nor tablet can connect at 300n, I am getting 130 on all connections for some reason. I do not know how longthis may have been going on, it might of been since day 1 because up until now my wife has been the only laptop user and now that I am on a laptop, it's something I noticed.

    I am currently on fw
    Tomato Firmware v1.28.7467 MIPSR2-Toastman K26 USB VPN

    I have no security on, I am doing MAC filtering only.
    Some other misc settings include:
    set region to JAPAN
    40MHZ is on
    tried channel 6 and 11
    set to upper and lower
    Bluetooth coexistene disabled
    transmit power 42
    transmission rate auto
    interference mitigation is none
    WMM is enabled

    Laptop cards tried are two Atheros AR5008x and an Intel 5300 Pro both should be able to connect at 300.

    Any idea's how to fix or settings to play with?

    What wireless cards are you using? Are they 1x1?

    I already provided this info - all wireless cards have 3 u.fl connectors each connected to an sma antenna
    Two are Atheros AR5008x and one an Intel 5300 Pro

    I had connected them at 300 speed at a friends house one a different brand router running stock firmware.

    With regards to it being 1x1, whats the difference, the router only does 2.4GHz (ASUS rt-16n)

    I have dual mode so its not exactly the same. But I have bluetooth coexistence on and connect at 300 without difficulty ONCE I set WMM to "Auto" or "On". Also do not turn on Overlapping BSS.... It will cut connection speeds as if its 20mhz. How crowded is your wireless in the area? Lots of others with wireless routers? I have WLAN Mitigation to "Auto". WMM Auto/On as noted but the other stuff in WMM I have disabled. Multicast forwarding disabled. Afterburner "Disabled". I'm set for US, channel 8, 40mhz, Upper side band as my 5.4 ghz is set to Lower side band. On some of the Intel cards they prefer channel set to "Auto".

    "With regards to it being 1x1, whats the difference"

    Some 1x1 devices can only do 150.

    I don't remember now if its 1x1 or 2x2 for the card, it was an ebay purchase from long ago, but I know I connected these at 300n on a friends router, so I am assuming they are 2x2, otherwise they would never exceed 150n.

    I just purchased an Atheros AR5BHB112 802.11a/b/g/n half height card which reaches a max of 450n, hoping to use it once the new 66u becomes more readily available, I guess I will just see how that one connects to the 16n I have now, it should arrive in 2-3 weeks from HK.

    I will update the thread then, but until then, I would really like to get these to connect.

    I just noticed that despite the settings I chose, the channel is set to 1 (I set it to 11) and the freq is set to 20 MHz in the Status->Overview page... no idea what's going on here

    Sounds like you found the problem.

    yah, now I just need to find a fix

    Apparently changing from JAPAN to UNITED STATES fixed the router being stuck in 20MHz and is now at 40MHz at channel 6 as I last attempted it to be changed.
    So... first issue fixed... but is this a bug in Tomato???

    Now, why I still won't connect at 300mbps is still going to remain an issue, hopefully when my 450N card arrives and if I see it fail to connect, I will conclude if it is the router or the current card I have that is the culprit.

    I was able to connect using a different Atheros card I found in the closet with one of the laptops at 300N, using the UNITES STATES region.

    Does this mean JAPAN somehow has a bug when it is set?

    When connecting another laptop, which at this time can not achieve 300N the connection drops again to a lower 140N, is this normal?

    XT, the COUNTRY when set restricts use to defined paramters determined as being legal for that particular country. The settings are hard coded into the wireless drivers. Japan is just about the worst thing to set, although it allows the use of 1 extra channel (which many clients don't support anyway) it restricts many other things severely including power level.

    I've always found SINGAPORE to be a good choice as that allows channels 1 to 13 with few other restrictions. But that's up to you to experiment. There's no really good guide - you can find lists online of what is allowed per country but that doesn't mean the content of such a list has necessarily been implemented in the wireless drivers. Many of the lists seem to be long out of date. I haven't found any of them to be a good guide as to what country to actually use. No two sites agree with each other :-(

    Thx Toast, didn't know it was hard coded, I though it was all software based.

    I will try Singapore, and experiment otherwise, if I fins any unusual or amazing findings I will post for others to see.

    I can hear the sound all across Tomato land of people changing their location setting to Singapore. The sound is deafening.

    Did you guy did few more test? Is Singapore really a better option? I noticed the latest Toastman's build is now default to that country.

    Testing Singapore :)

    I tried channel 13 yesterday. My laptop seemed to be able to see and connect. My Samsung smartphone, however, was confused and couldn't see the broadcast. Back to Channels 1, 6 or 11 for me.

    Is there any benefit to choosing an 8 or 9? Or does that just give you double the interference cause you're picking up the fringes of both 6 and 11?

    Yes, it would be a bad idea. You're then getting jammed (and are jamming others) by 6 and 11. There are only 3 available channels in reality. 1,6,11. However, if you are using G only, theoretically you can use 4 non-overlapping channels 1,5,9,13 - but that brilliant piece of information totally ignores the fact that everyone else is on 1,6, and 11 and you are therefore the "fly in the ointment". However, if you are in a quite place in the countryside, this would be OK.

    But as a general rule, 1,6,11 .... and those who use "in between channels" are actually screwing up the entire band for everybody, as is the stupid "auto" setting.

    The whole wifi thing will work as long as people are on the same channels. If they can decode each others transmissions, then they are able to wait until the other guy has finished before transmitting. OK, that may slow things down, but that's the problem with having a lot of people SHARING the wifi band. But if you sit on a channel that is "in betweeen" you can no longer decode any of the other guys as you're not "tuned in" correctly, so you (and him) will NOT wait for the other to finish and will both transmit at once, jamming each other.

    BTW - Channel 13 is not supported by most of the wireless clients I've seen.

    Try 7 ....

    Is that a joke? If not - why 7?

    just a small update for everyone, I am getting my full 300N now with my new Atheros adapter and region set to Singapore, I now feel more empowered for a feature I will not use often :D
