I bought a brand new Lenovo Y50 yesterday with the network card Intel Dual Band Wireless-AC 3160. The moment I tried connecting to the internet from my room I noticed something was wrong. At first I wasn't even able to locate any networks from where I was sitting, after a few minutes of shuffling the computer around my desk, I found my network at 3 bars, along with my neighbours network at 2 bars. I tried to connect, and 4/5 times it failed to connect. On the fifth try it connected, and when I checked the speed it was 10% of what I got on my 8 year old Sony Vaio (1down/0.1 up from 10down/1up). I then went downstairs and sat down right beside my router, and from there I achieved the full capabilities of my internet. I have my drivers up to date (188.8.131.52) for Windows 8.1 64bit, and the driver on my router is updated as well.
I googled some things and found out that so far we know that the card is in someway deffective, and there is no clear cut fix even after half a year of troubleshooting and complaining by the community. I came here to ask if we've made any progress and found a way to fix my connection problems?
Please know that any driver update to OEM (Original Equipment Manufacturer) adapters must be done through the OEM's support page, in this case Dell, as the adapters in this category, even though they are Intel(R) products they suffer customizations and adaptations in order to fit the system. Our drivers in our support page are generic and they may not fit the requirements of your system.

On a side note.
