I have a Y-560 that I bought about three months ago and am having trouble getting the wifi to work in N mode.
I just got a new Wireless-N capable router, and when I set it up to only transmit in N-mode, my wireless no longer works. In mixed mode (B/G/N) or even N/G mixed, it works. My roommate's Macbook works when it transmits only in Wireless-N, so I can therefore conclude the problem is on my end!
When I go to the device manager and click on the WIFI Link 1000 BGN, I see properties like 802.11n Channel Width for Band 2.4 and 802.11n Mode. I can switch n Mode to "Enabled" but I see at the bottom a property called Wireless Mode and the only options are: B, G, and B and G. No N!
How do I enable Wireless-N on my laptop?
The trouble may still reside with the router settings. Wireless N can be a more demanding mode.
For example, with a Linksys WRT160N, it was found that enabling QoS was required.
Here's some insight to get that full Wireless N 300mbit speed:
