The laptop was sent to me with the previous owner's software and settings, and I'm wondering if this is part of the problem. I would have simply restored the system using the recovery utility, but the previous owner did a clean install of Windows 7 Ultimate 64-Bit over the original Home Premium version, overwriting the drive and the Lenovo Recovery program in the process.
The laptop was manufactured in March of 2012, and is still under a 3-year extended warranty with a Windows 7 Pro COA sticker located inside the battery bay. It also has a few months left of accidental damage protection coverage (both the warranty and protection coverage have already been verified at the Lenovo site already). I intend to call Lenovo this week to see if I can get a replacement Recovery disk to restore the system. As I'm not the original owner, can this be a problem with Lenovo?

You can have the existing "Intel PROSet/Wireless WiFi Software" repair itself or else just reinstall it. When you choose to uninstall it from Control Panel > Programs and Features, that should bring you to an option to repair the existing installation.
Alternatively, download and install the latest version of the "Intel Wireless LAN (11abgn, abg, bg)" software or else download and install "ThinkVantage System Update 5" and have it pick up the latest version for you.

I was writing up a detailed request for help here and going through every setting. The one thing that seemed to do the trick, though it could have been random (since, again, it is intermittent) was to make sure that Internet Connection Sharing on the wifi card was turned off. Feel free to give it a try.
Also, I have been told by support people that this is also often fixed by
- having the latest Intel drivers (direct from intel - I am now on version 15.3.12 dated 9/30/2012)
- turning roaming aggressiveness up
- checking with the network administrator of the location you are at if your Mac address is being blocked (often happens if you have a virus)
Other things that have sometimes seemed to help in the past
- disabling all the network connections that you don't need
- using google's servers for DNS - 220.127.116.11, 18.104.22.168
Please let me know if any of this helps and if you have learned anything else. 50/50, I was just lucky with the ICS and the problem will pop back up, so I would love to know.

1. Downloaded Windows 7 64-bit .iso file and burned it to DVD
2. Did a fresh install of OS using my COA ID.
3. Installed the latest WLAN driver(1005.32.306.2012) and updated all critical Windows updates(no "optional" files).
4. Installed latest version of Lenovo System Update(5.01.0005), and made sure to install all needed drivers & utilities. To test each utility I didn't install ThinkVantage Access Connections, just using the Windows WLAN utility).
5. Ran Lenovo Hardware test(including wireless) and everything passed.
Same thing. I have no problem getting online when connecting at home. When I went to my favorite coffee shop with wireless, I was unable to even get to their logon page to enter in their guest password. Normally this page popped up, and after entering their guest key password I was on. Now I can't even reach this page.
I think my next step will be to install Access Connections and see if it helps. If not, I'll probably do a full Lenovo restore, run updates, and see if that solves the problem. I do like the laptop with a clean install, though.
daveboston: the Internet Connection Sharing box is not selected in the Wireless Network Connection properties section, and the newly installed software on the laptop is virus-free so it's not likely a Mac address issue. I'll give your other recommendations a try as well.

A couple of other things, did you set up the type of network in Network connections (i.e. public, home, etc.) for each network you are trying to connect to? Have you tried running a different browser than I.E.? What are your security settings for I.E. set at?
