Windows 7: Work Lenovo Laptop will not stay connected on my Home Network

I hope someone can help me with this. I work from home (office is 70 miles away), and my Lenovo T420 Windows 7 will not stay connected via WiFi to my Verizon MI424WR ver I router. I had this problem with my old router (MI242WR rev E), and I was able to fix it by turning off the Power Management option to "power off to save power" My Lenovo is using Centrino Advanced-N 6205 Wifi chip. It reads as "working properly".

It seem obvious that there is an issue between the Lenovo and the new MI424. I have 10 other devices connecting to the MI424 without a problem. I have shut down devices to ensure that their is not an over burdening the AP issue.

Specifically, the Lenovo successfully pairs with the MI424, tries to establish an Internet connection, fails, and drops the connection (or the router does - I assume it is the laptop.) It's worked great for about 4 hours this am, then it quit working. I:

- shutdown the laptop, pulled power and battery
- shut off the network, pulled the plug and let it sit for a while
- restarted everything and the issue will not go away

It works fine @ work with a Cisco Network.



My company uses some McAfee SW for laptop security. Since I was blissfully working for hours and this just started up, I do not think that has anything to do with it. But who knows? Any ideas?

OK, I just thought of something. The problem started at the same time I powered up my wife's new iPad4. So, after turning off the iPad 4, I was able to log on. Since I completely bounced the network (unplugged and left unplugged the MI242WR), I would think that would release all the IP addresses in the router. I am back to work, and afraid to turn the iPad back on.
