VGNZ1 wifi drops & 802.11n

[Schouffy]

Hi,

I'm having an issue with a brand new VGNZ1 on win7.

The wifi connection drops several times by minute (even though the frequency of drops seems random).

Also the transfer rates are sometimes very low (like 1KB/s)

I have in the windows log the same things than the guy below and a bunch of other (from what i've seen by searching internet for my issue)

After some research i noticed that the problem went away if i deactivated the 802.11n mode in the network adapter advanced settings. But if i do this i will be limited to 54MB/s. The router is freebox (french ISP router) 802.11n capable.

How can i have it working at full speed ?

I already have installed latest drivers for intel centrino 6200 AGN

Thank you for any help you can provide.

Can you please check your exact Vaio Model - you will find the correct model on the screen surround.

The reason I ask is because the VGN-Z1 Vaios have not been made since 2008.

Which wireless driver do you have installed - look in Device Manager -> Network Adapters - Wireless LAN?

Sorry my mistake, computer ref is VPCZ1.

Wireless is intel centrino advanced-N 6200 AGN

That is newer than anything on the Sony download site - 13.2.1.5 seems to be the newest dated October 2010.

There is a newer one on the Intel Download site dated 3 April 2011 but I don't know it that helps.

The intel driver is what i installed.

Am i supposed to install intel drivers or do i have to stick with what sony provides ?

Do you have any other idea ?

Thank you

Hi,

just checking up if anyone has an idea, my problem being not fixed. It's a shame to have fast equipments and slow rates of transfer...

Thanks for any help.
