At work, Lenovo X200 type 7450-AG7 while docked, wireless will work flawlessly- no cable attached to dock-
When I push the button on the side and the dock turns green to release, wireless is still connected to the same network but will not go out to internet or intranet.
I have deleted any profiles that were stored in the wireless networks and still when it finds the only network here. it still stalls out- any idea

OS is XP 32 bit

Have you checked with your IT department?  This might be by design, where the network intrusion security detects a signature from a database of allowed systems and without the dock, your signature changes and is then detected as an intrusion on the network and you become fire-walled.  It could be a security strategy so that not just anyone in range of the wireless can hack away at the network without having a certain allowed signature that can change with hardware configurations.

The only thing that i can think of- is maybe onbe of the profiles is screwed up- either profile1 or the dock profile- wonder if i delete it if it would work

After disconnecting from the dock, have you tried rebooting?  The wireless adapter could be freezing up when you disconnect from the dock.

So you get a change in profile undocked?  May not have the same credentials as the working profile.

Highfive Gives IT Their Time Back

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

Years ago I experienced similar issues with Dell laptops and it was the Profiles but the fix had to come from Dell, it was not something we ever found a cure for even after months of troubleshooting.

My instinct is there may be a way to clean the Windows XP Registry and then try creating the Profiles again, maybe that would help!  So...

1. Delete all the Profiles
2. Disable the wireless connection
(may need to reverse the order of 1 and 2, and may need to REMOVE the wireless adapter in 'Device Manager' - to completely clear the Registry entries)

3. Reboot (1 or 2x times to be certain)
4. Run your preferred Registry clean-up tool (mine is Eusing Free System Cleaner)
5. Reboot again
6. Add the wireless device back into Device Manager
7. Create the desired 'Docked' and 'Undocked' Profile

A symptom we had with the Dell was a 'blank' wireless Profile showing up on the 'Available hardware profiles:' list OR if you selected a Profile and clicked into 'Properties' the 'Dock ID:' or 'Serial Number:' field would show Japanese-looking characters! (this is an important detail !)

If all else fails: Have you tried using a USB wireless network adapter for reference purposes to see if the X200 behaves differently under a separate adapter?  I feel like this would be a good test to confirm whether the built-in wireless driver or firmware might be contributing to the issue.  If that is the case, then the long-term solution to the issue is clear (not cheap, but clear) --- Buy some external USB wireless adapters and sell the Docks on eBay!

I hope something in this advice helps, if so you know what to do.  Good luck!

Registry Cleaners.  Just say no.  

Its registry cleaners that can cause weird things like this to happen.

It was a profile issue as i expected- when docked I deleted the undocked profile as well as profile1 and when rebooted it worked

I participate in Experts-Exchange by answering questions where I feel confident in the subject matter.  This question may not be worth 500 points, but I feel a significant amount of effort went into the answer I provided, so at least 125 points should be awarded.  If the Premium Service member, yoz_man, withdraws the question or accepts his own answer to it and awards NO points to anyone else for assisting, I will feel cheated.  I do not go for exceedingly complex questions about database tuning or Visual Basic programming because I am unskilled in those areas.  If I cannot answer less complex questions such as yoz_man's and get points for them, I might as well quit the service and spend my time elsewhere.  Please request yoz_man grant at least some points to us for assisting with the solution (unless the "profiles" he is speaking of are something completely different than the "profiles" I wrote about).  Also, with keywords such as "Dell", "Profiles", "Registry", "Docked", "Undocked", "Dock ID:" and "Serial Number:" (including colons), I feel this solution may be of use to other Experts-Exchange members.  Thank you.
