After the OS update, my wireless speeds have dropped to a crawl. around 350 to 500 kps on my home wlan. Every other device on my wlan runs between 6 and 10 mbs. I've only found posts about deleting the wireless network, recycling the router and then creating a new connection. Obviously I don't have access to every wireless router I connect to in able to do this and the connection is consistently slow no matter what network. Any suggestions on how to fix this?
I would first try resetting your PRAM, then create a new network location.
Resetting PRAM and NVRAM
- Shut down the computer.
- Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
- Turn on the computer.
- Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
- Hold the keys down until the computer restarts and you hear the startup sound for the second time.
- Release the keys.
Once you've done so, delete your network locations in System Preferences and create a new, fresh location.
