    Exactly the same situation. But in my case I use a 3com 11g router.

    I went into Preferences/Accounts/Login Items and found a file called SMSIWirelessKicker or something like that.

    Highlighted it and clicked the minus sign to delete, RESTARTED, reconfigured Airport and appear to be up and running.

    The problem exhibits itself in a fresh install where that log-in item does not exist and hasn't been used. However by restarting the computer and reconfiguring the wireless settings you may have temporarily solved the problem.

    Either the problem you experienced was different to the one discussed in this thread or you haven't given the wireless enough time to fail.

    I am having the same problem. After installing 10.5 my Power Mac G4 is very slow on the internet. The connection is worse than dial up. I have never had this problem with 10.4. My MacBook Pro is working fine, with a fast connection. I'm sorry to say 10.5 seems more like beta software than a $129 upgrade. I hope this problem is fixed soon, or I will have to go back to 10.4.

    Ok, so I'm having the same problem! Thought it was weird when I was trying to play my iTunes music through speakers connected to an Airport Express. The sound kept dropping out, I thought it was just a small intermittent problem, but it soon started to annoy me so much I can't play my music that way now.

    Internet is also slow (when I say slow, I mean slooooooooooow), just checked my transmit rate now and its down to "1" and bouncing around a little, highest I have seen it is "11".

    I did a full clean install of Mac OS X 10.5 Leopard on my PowerBook G4 (1.5 GHz). I have an Airport Extreme, and two Airport Expresses.

    My flat mate has a Macbook, but won't be installing Leopard until later - it will be interesting to see if he has the same problems.

    I'm having very similar issues with my Mac Pro, so I don't think it's just PowerBook G4 machines. Mine starts out at 54, then drops to 11, then to 5, and then goes back to 11, but never returns to 54. Also, I'm using an Airport Express, so even with Apple's own products this happens! Did they test this at all? My MacBook Pro works fine with the same Airport Express. I tried reinstalling clean incase the upgrade was an issue, but that hasn't fixed it either.

    On an unrelated note, my fan runs a **** of a lot louder since I installed Leopard.

    -If- the problem is truly caused by the TCP bandwidth maximizing features, you can disable that by typing (in Terminal)

    sudo sysctl -w net.inet.tcp.rfc1323=0
    sudo sysctl -w net.inet.tcp.rfc3465=0

    When asked for a password, enter your admin password. You'll only be asked for the first command. One or the other of these -might- help, but I have no way to know. Post your results.

    For more info on the sysctl command, see the manual page for sysctl by typing "man sysctl".

    Is sysctl the same as Leopard's Self Tuning TCP? Apple apparently added this as new feature for Leopard.

    Hi, I am having the same problem on my Mac Pro clover... but non of my other computers. Before the install of Leopard, I had solid bars, as I have on all of my other computers. After the install, the reception goes up and down, sometimes disconnecting from my airport extreme network. This is only happening on my Mac Pro. Strange. I went through all of the trouble shooting steps and it is still happening. The last firmware update is there, installed a few weeks ago, it is a fairly virgin computer. It just has airport issues now.

    I don't have a file called SMSIWirelessKicker on my system, so that can't be causing the problem in my case. It looks like that is a program that's installed by Verizon's VZAccess software for EVDO data access.

    sysctl is a terminal utility for changing kernel settings, which could include, but isn't limited to, the self-tuning TCP. I don't know anything about those particular settings, or if they're related to the self-tuning TCP stack.

    Edit to add: I just tried these commands; the first one worked but the second produced an error message:

    nchaimov:~ nchaimov$ sudo sysctl -w net.inet.tcp.rfc1323=0
    Password:
    net.inet.tcp.rfc1323: 1 -> 0
    nchaimov:~ nchaimov$ sudo sysctl -w net.inet.tcp.rfc3645=0
    net: class is not implemented

    The problem still occurred after setting these options.

    I was experiencing intermittent wireless (airport) and slow connections. I thought it was because I was sinking my Apple TV, but after I restarted the laptop (first time since the install everything seems to be working fine.

    I am getting xmit rates of @40 while loading the network with other activities and it hasn't dropped.

    (fingers crossed)

    I tried the same thing and had exactly the same result.
    However it did seem like with the rfc1323 value set to zero the Airport was able to recover better when the bandwidth did drop off which lead to a longer (but unstable) network connection.
