Lenovo Y510 notebook has an Intel Wireless WiFi Link 4965AGN wireless card. My router is a Linksys WRT54GL, set to use WPA-TKIP. Problem: notebook can connect to the network using its wired LAN adapter, and can connect using the wireless adapter if I disable encryption. If I leave the encryption enabled, the notebook can see my wireless network but cannot access it; running ipconfig /all shows no IP address, but a message "Media disconnected." If, however, I plug in my Edimax wireless USB adapter, I can access my network and get onto the Internet, even with WPA encryption enabled. Is anyone aware of a compatibility issue with this notebook / OS / encryption combination? BTW, I upgraded the Intel wireless card driver, and flashed the BIOS for the notebook - no change.

It wouldn't be a notebook or os compatibility issue per se.....

In what way is it unable to connect? Are you getting an error message?

My hunch is that your laptop is trying to access the network using the wrong sort of encryption. Try setting the settings to connect to your wireless network manually, making sure to tell it to use WPA-TKIP.

I think you're right that it's not a notebook or OS compatibility issue because I can, in fact, get onto my network and out onto the Internet either thru its LAN adapter or thru an external USB wireless adapter. The error message when trying to connect thru the wireless card without disabling WPA is just a standard "Cannot connect to ..." after selecting my wireless network and manually typing in the WPA passkey. Again, if I check for an IP address by typing ipconfig /all at a command prompt, all I get for the wireless card is "Media disconnected," even though it identifies the card by its manufacturer and physical address.

When i meant manually connect, I didn't mean just type in your password. There's an option to manually set all settings for any network of your choosing....See here:

Actually, I did try to connect manually, and had the same problem. The issue seems to be that the notebook cannot connect to my network using its own Intel wireless card as long as I have encryption set up using WPA-TKIP. As I said, if I disable encryption, it connects up with no problem. The "Media disconnected" message seems fairly common, and not limited to just Vista. I'm just curious to know if anyone else had experienced the same thing.

You're right - Microsoft Media Sensing technology has been around since the days of Windows 2000 and incorporated in certain NICs. It's a feature for TCP/IP. The link below not only explain what it is all about but it also tell you how to disable it. Read the whole article first before you do it.

Will it connect to other networks wirelessly? Like have you tried connecting in a coffee shop or other free internet source?

I haven't tried it with any other wireless networks, although I can see two others in the list beside my own. Remember, if I turn off my WPA encryption, I can connect to my own wireless network with no problems.

UPDATE: Disabled Afterburner, one of my router's firmware options, and that fixed it.
