Half Moon Bay. Thanks for the advice. I appreciate your response but unfortunately it didn't work. The proset 'trouble shooter has a manual diagnostic that runs a series of tests. It keeps failing the 'association test' and , despite acting on the fixes suggested by the trouble shooter guide, it still doesn't work. So I'll keep using Windows too. There are a lot of proset queries on the message board. I hope Dell and Intel are reading them cos it ain't good enough.

More info.
I downloaded the file suggested by Halfmoonbay.

Opened and installed the file

Tried to reconnect using pro set. Didn't work

I went to the control panel.

Opened Network connections
Right clicked on the wireless connection (which also showed that proset was managing the connection)

Selected and ran repair

rebooted the computer.

It worked.
Rebooted again to see if it still worked. It does

so far so good.

More Info 2

Problem applying profile issue has reappeared.

As Halfmoonbay pointed out, you can re-establish the pro set wireless connection each
time by going opening the network connections icon in control panel, right clicking and selecting 'repair' but at this stage it's not a permanent fix. Any more thoughts out there?

Another update.
Downloaded the following from Microsoft.

WindowsXP-KB914440-v12-x86-ENU

After installing, rebooting and 'repairing'(as above) this seems to have fixed the problem.

My Intel PROSet wireless was working well until I downloaded and installed the most recent version from the Drivers & Downloads site:

Release Title: Network: Intel (R) Wireless WiFi Link 4965AGN, Intel(R) PRO/Wireless 3945ABG Network Connection, Driver, Windows 2000, Windows XP, Windows XP x64, Multi Language, Multi System, v.11.5.0.0 (TIC148234), A13
Release Date: 11/19/2007

Then I got the 'Problem applying profile' message and could no longer connect to wireless networks that had security turned on. I went through a chat session but no joy: the support technician got me connected by turning off PROSet and letting Windows manage the wireless connections.

Then I searched around on the Intel support site and found the URL below. I followed the instructions on this page and everything now works great again.

I have a 1.5 year old Inspiron E1505 running Windows XP Media edition XP Service Pack 2. The wireless network hardware is the Intel 3945ABG.

This issue has caused me intermittent problems in the past. Recently, it became constant. I tried all of the solutions below, and nothing solved the problem.

Finally, I uninstalled the most recent version of the Intel ProSet/Wireless driver...rebooted (also did a "scandisk" during the reboot) and then reinstalled a previous version. It seems to be working.

Here's the version that is working for me: Multi Language, Multi System, v.11.1.1.3 (TIC146561), A12

And a link: http://support.dell.com/support/downloads/download.aspx?c=us&cs=19&l=en&s=dhs&releaseid=R164255&SystemID=INS_PNT_E1405&servicetag=&os=WW1&osl=en&deviceid=9540&devlib=0&typecnt=0&vercnt=7&catid=-1&impid=-1&formatcnt=1&libid=5&fileid=220545

I doubt that Dell will do much about this issue. It has never been truly fixed in the 1.5 years that I've owned this computer. And now Dell has moved on to Vista, so this XP issue is certainly way off their priority list.

FYI... I have a Inspiron e1405.

Good luck.

It just happened to me again. So, I'm going back to the version recommended by locoqueso. Whew.
