Vaio cannot connect to N type wireless

[paulie]

Hey guys!

I have a vaio EB2S1E and one router Linksys WRT120N. Both devices have the N wireless standard. When i set the router to Wireless N-only, my notebook cannot conect to it anymore, i see it as a device but after i enter the SSID it will not connect. If i leave it to Mixed or Wireless G-only or set it to Wi-Fi Protected Setup the notebook connects fine and i am amble to copy with 2.5 mb/sec :??:
I have posted a picture with the settings, can anyone tell me what am i doing wrong?



PS I have two onboard LAN cards one Marvell Yukon 88E8001/8003/8010 PCI Gigabit Ethernet Controller and one Marvell Yukon 88E8056 PCI-E Gigabit Ethernet Controller. Is there any difference between them, besides the name? Which one is better to use with my router?

Thank you for reading this!

Looks like you solved this already.

As you found out, using the manual wireless connection set up in Windows 7 allows you to choose WPA2 and AES encryption which usually works best with Windows 7.

Yes, the router was set for TKIP or AES authentication, when i set it up to just to AES and set the wireless connection manually to AES it worked fine.
Thank you for your support!
