    After installing lion my wi-fi connection is constantly dropping out, and sometimes when it is connected, web pages don't load.

    Anyone else got this problem? This needs to be addressed urgently by apple as having the Internet is one of the most basic needs when having a computer.

    Yes I have the same problem! I have to keep refreshing pages because they dont load the first time. Does your safari take up to a 100% CPU as well? I had to change back to Chrome which is a shame because I really like the new features of Safari. Safari just really slows down my 2011 macbook pro.

    I am experiencing the same problem with the Wifi. But safari does not cause my cpu to be at 100%. Although, my laptop does tend to run a bit hotter than it used to do on Snow Leopard.

    I had this problem as well but after turning off airport then turning it back on, and a restart....I don't seem to have as many issues.

    I had similar, except my entire net connection wouldn't work. Everything apart form MSN Messenger refused to connect to the net. Spent an hour on the phone to Apple and eventually worked out Avast was the issue. It doen't like Lion, so if you've got it, uninstall it, empty Trash, and restart. That cured it for me. I don't know if any other anti-virus software is causing issues, but if you've got it installed it might be worth doing as I described above.

    I've found a workaround for this that seems to be working on my 2011 MBP.

    1. Systems Preferences -> Network
    2. Under "Wi-Fi", click on the "Advanced" button.
    3. Under the "DNS" tab, add the Google Public DNS -
    4. Click OK, then click Apply.
    5. Turn WiFi OFF, then turn it back ON again.

    Hopefully there's a fix for this soon but so far, this works like a charm on my MBP. Way better than manually having to turn wifi off and back on again every time I wake the laptop from sleep.

    Good luck!

    I noticed with Lion, if I put my MacBook to sleep (close the lid) and re open it, the wireless gets dropped. In SL it would automatically join back to the wifi.

    The only way I can fix this in Lion is to goto the Wireless icon in the task tray and manually select my hot spot.
