I've had my T410 for about eight months, and have never had any problems with wireless connectivity before. Now the wireless adapter won't turn on. I'm on Windows 7. These are the symptoms:
I've read a number of threads on this, and have tried all of the following:
None of these activities has produced any change. Anybody have any ideas?

I'd just like to update this thread to indicate that none of these solutions has ever worked (and make one final plea for any other ideas). Lenovo seem unable to help. This seems to be a fairly common problem affecting *410s and *420s. Not a lot of people seem to have got it fixed to complete satisfaction. I think that's really disappointing.
I'm not one for drama, but after this and a related, critical, unaddressed issue I've had with the dock for this laptop, I may very sadly switch brands after 15 years of ThinkPads.

From the description/solution i have read, have you tried
Right click computer->select Manage
Device manager->Network adapters->right click->Properties
a) Turn on/off
b) Remove it, next time when it boot up window 7 would recognize it can try to install drivers for it
c) upgrade/downgrade the driver
There are 2 unlikely possibilities
b) You turn off the wireless radio in the BIOS
c) One of your wire is loose, misconnected. Its quite easy to see, just remove the palmrest / battery compartment (follow the hardware manual), it's not difficult.
I have encountered your situation before, with totally gone wireless radio, it happend after one lousy update (lenovo or microsoft)....there is no cure. The fastest way I test it is to create another partition around 30GB, download the official window 7 for 30 days trial, install it and test if it was the opearting system/lenovo drivers etc. (google digital official window 7 download)

Well, it sucks, but trust me, lenovo is still a much better brand. I have a lot of users with all different brands here and most of them have more problem, all kind of weird issues.
The last few times I had this radio problem was Access Conneciton, too hot in the wireless card compartment, the wireless card is bad. The last scenerio, depends on where the card is situated, slight bending (like pressing your palm on the palm rest) would on/off the card.
The fastest way I have found, without going through all the upgrading/downgrading/reinstalling device drivers, is to create a new partition, put in a fresh window xp/7 and see if the sympton is there. Or you can download virutal PC (free) from Microsoft, put in xp (free for win 7 pro above) and try again. it just may be something screw up during one of the updates and mess up the operating system/device driver. Anyway, trying the new win 7 partition way takes around 20 mins and is a great exercise ot learn, as future issues one can quickly identify if it was hardware or software problems

Er, just out of curiosity, you don't have the ethernet cable plugged in, correct?
because access connection, if profile is set to "best available network" and both ethernet cable and wireless is available, it would select the ethernet. Then it would turn off the wireless if you tick the settings to turn off wireless when in this mode.
Or since you have mentioned you have a WWAN 3G modem, could you have select that as the preferred device and automactially turn off the others?
Small possibility but we may never know B-)

I have seen mind turn off and not like to turn back on. This fixes on a login and log out and seems to be an issue of Windows, Access Connections, and the Intel Connections fighting.

Did anybody find a solution for this?
I bought a new T420s. The second week I had to send it in service because it was not turning on anymore. I couldn't convince them that the laptop suddenly restarts several times a day. And only after two weeks when it did not start anymore they told me to send it in the service.
No they brough it today. They made my day happy for 10 minutes until I turned it on and the wireless problem described in this topis apeared. The Inetl diagnostics tools installed with the card say: "Hardware radio is off". It worked before being send into the service.
Now, the wireless switch is on and I see the adapter installed by "no wireless connections available".
Pressing Fn-F5 it tells me to turn on the radio (the switch thing). But that is already turned on.
So I called again to ask them what is wrong. They told me they would send me a new mini wireless card that I can replace myself. I received it today, replaced it. BUT THE SAME BEHAVIOR!!! (((((((((((((((((((((
So I wonder, can the service guys (Wädenswil, CH) be so unprofessional to have forgotten to connect/enable the switch button?
1. The wireless LED is not turned on at all.
2. BIOS has wireless enabled
3. Device Manager sees the unknown network adapter (when driver uninstalled) and the Intel Wireless adapter (when driver installed)
(This double failure means a divorce from Lenovo products for me. Once I solve this issue I sell the laptop.) Yes I know service is better than other, but I want something that doesn't need it at all.
At least the Dell guys send a guy (freelancer service guy) at my place to fix the isssue. Now it is not only the costs for shiping it and investigate the problem (that are on my side) but also the productivity problem now costing us more than one month not beneffiting 1 minute from this laptop.
A very sad,
