I know this thread is a few months old but I figured I would post a solution to the irratic keyboard issue.
When typing on the keyboard with slight enthusiasm, all of a sudden the computer will "freak out" and type random letters and the keyboard will no longer function unless you bang on the keyboard (well that worked in my case). Also, when repeatedly pushing the number 6 button on the num pad it would type: 6666666'666'6''6''6666'6.
Most users, with a little searching, can find post about it being really bad when the "Always On USB" is set to 'enabled' in the Bios settings which is true. However, the main cause is the power that the "Always On Usb" feeds and this causes a shielding failure between the Ultra Bay and the keyboard's EMI Shielding. When you type on the keyboard, the keyboard's EMI shielding will either touch or come extremely close to the Ultra Bay Item's shield and cause a feedback and in return "freak out" the keyboard.
OK....here is what I have done and for two days now, with the USB Always On set to 'enabled', I have not seen any indication that the irratic behaivor is happening still.
1. Power off the machin
2. Remove the Battery
3. Set the little switch button, under the battery, to 'unlocked'
4. Hold the switch button in the middle of the bottom cover to 'unlock' and remove the item in the Ultra Bay slot. (In my case, I removed my Optical Drive).
5. Using ESD resistance tape, tape all metal surfaces possible on the Optical drive. (I have read that on the new Ultra Bay Video Cards that Lenovo just released for the Y500 will require you to place tape on the top of the heatsink because it comes into contact with the shield on the bottom of the keyboard)
6. Once you have taped up the metal surfaces on your Ultra Bay device, reinsert it very carefully not to tear the tape. Should slide right in pretty easy unless you went "Chuck Norris" with a bunch of tape.
7. Relock the little lock switch under the battery, insert the battery and lock it and enjoy!
PS - I know this kind of solution is pretty "Ghetto" and should not be needed but what do you expect from a CORPORATION? I mean, do you really think they care if you have an issue on a product that you already gave them your money for? To be honest, they probably "laid off" the best QA guy/gal, who had probably been working there for almost 30 years because he/she was getting close to retirement and they didn't want to pay and now we are stuck with Laptops that were not QA'ed very well. Sorry Guys/Gals! But we can let the "Free Market" do it's thing because I can tell you that I will never ever ever ever ever purchase anything from Lenovo again.

OK party people. Here is the result of my "workaround" for the erratic keyboard issue.
After putting the tape on the optical drive exposed metal parts, the keyboard works great. However, as soon as you turn the "always on" usb to the enable setting in the bios, the keyboard starts freaking out again. I believe this to be cause not only by the bios patch but also by hardware poor design. I am sorry but it seems after lots of use which I monitored for the issue, that the only way to have this laptop to function properly is to perform the workaround that I listed in detail and also to never ever user the USB Always on feature.
Way to go Lenovo! <big sarcasm>

I haven't had any issues with the WIFI adapter cutting out. And just you stating that you had to re-install Windows to make it work, would lead me to conclude that it was a driver issue. After re-installing windows, it probably updated with an install of the wifi adapter driver and fixed the issue. If it happens again, navigate to the "device manager" by right clicking on My Computer and then clicking "manage" and you will find device manager. Here you can view the status of your drivers and see what condition the wifi adapter driver is in. Sometimes if I have an issue with an "add-on" component like an adapter, I will uninstall the driver and re-install it and it will work properly. Always process of elimination starting with the easiest thing first. Re-installing an OS should be your next to last resort. The last resort being "setting the laptop on fire" or swaping a piece of hardware like the screen. lol
