After upgrading my HP DV7 laptop with Windows 8, I found that my wireless connection was extremely slow. My adapter is a Broadcom 4322AG. This appeared to be the same problem as was in the forum 

Slow WiFi with Broadcom 4322 and Windows 8 CP.

Following the advice in that forum, I changed the security from AES to TKIP and everything seems to work fine.

    Thank you so much for sharing your solution! My problem was that i downloaded in less than 1 Mbit/s and uploaded around 15 Mbit/s. Then I changed to TKIP just like you said and now I get around 21 Mbit/s downloading and 19 Mbit/s uploading. All this on a MacBook 5,1 :)

    That was not the way I solved my problem with Windows 8 running a super slow internet connection.

    I downloaded the Windows 7 drivers for my Broadcom 4322ag wireless adapter. Then I opened the Device Manager & uninstalled my wireless adapter (checked the box to remove software). Then I right clicked the setup.exe file & set it to run in Windows 7 compatible mode & arn as administrator. Then reinstalled my driver. Worked perfect.

    If you are running Windows Pro or Enterprise you could also open gpedit.msc (at desktop use Win key + R & enter gpedit.msc) expand Administrative Templates...Network...QoS Packet Scheduler & double click on Limit reservable bandwidth. Select Enable, change bandwidth limit (%) from 80 to 0 (zero) & Ok that.

    You should have great internet connection speed now.

    Hope this helps solve your problem.

    This does not work if you are using 802.11N network connection since TKIP does not exist on that.  :(
