    I've read countless pages, sites, threads, blogs, links, articles about Snow Leopard and its slow wireless problem.

    I just upgraded 2 days ago, and I'm afraid I may have to format and go back to Leopard unless there is a fix for this.

    Does anyone know if there has been a discovered remedy to this issue?

    I'm running 10.6.2 on a 15" MBP C2D and using a AEBS router.. No firewalls.

    Let's define slow. Try out this speed test, or another if you'd like.

    Edit: For comparison, here's my results.

    Wireless (g):
    Down: 7 Mbps
    Up: 0.5 Mbps

    Wired (ethernet):
    Down: 10 Mbps
    Up: 0.5 Mbps

    Ill run a test when I get home..

    But I have 12mbps service. Took me 24hrs to download 8gb from a secure server. Took 3 hrs to transfer 1gb from my home server to my MBP.

    I'm averaging under 1mbps dl speed. Again, ill post when I get home.

    My other wireless devices are getting full speeds.

    Another example of my problem.. EXACTLY to the "tee".

    http://discussions.info.apple.com/thread.jspa?threadID=2286188&tstart=-1

    I looked up my service btw, and I have a 20mbps service. Woot

    I ran speed test.
    Wireless MBP, 10.6.2
    DL: 1.56mbps
    UP: 1.68mbps

    Wired PC, direct in to the router
    DL: 20.62mbps
    UP: 1.92mbps

    Stopped by the Apple store tonight, but they have never heard of this issue. This is a serious deal, and a deal breaker for me. I'm afraid i'm going to have to downgrade tomorrow.

    You've probably checked this, but is the speed the same no matter the browser you're using?

    There are some things you can try, like a DNS flush. Just run the following command from Terminal,
    Code:
    dscacheutil -flushcache
    You can also doing a traceroute to figure out where along the network connection the speed is being throttled, whether it's the router, your ISP, or elsewhere. Traceroute can be run from Terminal or Apple provides the built-in Network Utility app. Just need to find an IP or domain name (google.com). I'm not saying I'll be of much help with the traceroute results. If you notice a section that's taking much longer than the other parts you can try running the whois command on that IP to see where it is. This may help you determine if the IP belongs to your ISP or some other network.

    Good luck.

    Maybe you've tried this before. Go to System Preferences / Ethernet (if you're wired) / Advanced / TCP/IP /Configure IPv6 = Off

    Unless you are in a dedicated network which needs this protocol, talk with your sysop, if you are just interacting with internet, do so. Helped me A LOT!!

    IPV6 is off.

    Just ran another test. Must be a good day..
    DL: 7.39
    UL: 1.46

    I'm going to format and downgrade tonight. Can't take it anymore :( Apple has officially disappointed me for the first time ever.

    Have you checked things like MTU and such, which will impact network performance. What is good for wired is not always good for wireless.

    TinkerTool System is one tool to use to make these changes.

    Take care,

    I'm back on leopard. And look.

    DL: 20.59
    UL: 1.96

    There are some serious issues with SL with hundreds of people experiencing the same. Until Apple takes the steps necessary to correct it, i'll stay with 10.5.

    Yeah SL sucks.. I constantly get the freeze ball and the slow wireless..

    But I think I fixed the slow wi-fi with creating a new location under Network proprieties.

    Wireless (N)

    Down 5.08 Mbps

    Up 0.19 Mbps

    According to the router I connect at

    Downstream 6,592 Kbps
    Upstream 448 Kbps

    So allowing for QOS issues from the Router and ISP I'd say all is reasonable.
