Airport not working after Upgrade 10.5.8 to 10.6

Further to this, this new and less sensitive airport is causing me serious problems. I have two work locations. Both are mere feet from both a Time Capsule (which is enabled for wireless access) and an Airport Express which are running as a WDS network.

I had a situation tonight where I could not get a stable connection to my network at all from either location. Wired worked fine. Wireless from my sofa seems stable (where I am now).

But before Snow Leopard it all worked like clockwork.

SL has hosed my Airport sensitivity.

I am having a simular situation with the Airport. I just purchased two MacBook Pros less than two months ago. Both are dropping the wireless at the same time. This has never happened before but I install Snow Lep two days ago and this issue has happened three times now. Right now I am using a Liksys Wireless G Broadband. I do have a PC connected to the router and it is working fine.

I had the exact same problem on my iMac (late 2007) when I installed SL over the existing 10.5.8. I tried reinstalling SL twice without success. The only way to solve it was to back up everything, erase the partition and do a fresh install of SL. Airport works now like it's supposed to.

A bit drastic to erase everything, I know, but I don't have much on that partition so it wasn't a huge deal for me.

My morning so far:

- Get up, open MacBook on sofa. Wireless surprises me by connecting immediately with a strong signal.
- Work for 20 minutes.
- Totally lose wireless connectivity.
- Check with my two iPhones, both get good internet connectivity immediately.
- Sit for ten minutes scanning for networks, turning airport on and off and trying to renew DHCP leases.
- Curse myself for the billionth time for installing SL on my six-month-old machine.
- Open Network Prefs, create new location.
- Connect to Wireless network immediately with no problem, RSSI -59. Rock solid.

I've finally made progress on this.

It seems that what may be the solution for me is uninstalling VMWare (with the provided installer). This seems to have made the difference in that I can now connect and have a solid connection.

I will report back if this is a false victory.

I've now been connected for a couple of hours. Further, I have reinstalled VMWare and it is functional. It seems that uninstalling it and reinstalling it solves the problem.

I went to System Preferences>Network, I actually deleted the airport connection by clicking the minus sign at the bottom. I rebooted and set up the airport connection again. I clicked apply. I chose my wireless network and entered my WEP key and BOOM! I was back online again. The response time in airport has dramatically improved. It is as fast as its supposed to be now.

This was frustrating I tried a number of things without success. patrick ellis1 August 28 2009 suggestion worked however. My problem was we have 2 macs, one the airport functioned (IMac) after Snow Leopard upgrade the other not (MacBook): I could not switch it on (activate). The one that worked by the upgrade had no address entries for the airport (any help? what was the problem in the first place?).
