T420 - Slow wireless connection [ Edited ]

[Miba]

Hi

I just got my new Thinkpad T420 a couple of days ago now, but the wireless network / internet connection is bugging me.

I am unable to obtain anything higher than ~60kb/s, just occasionally it will land on 800kb/s for a brief second and then return to 60kb/s. Our internet connection should allow the T420 to download with 1MB/s, but settles at those 60kb/s.

I have already tried to download every update through Lenovo's System Update 4 and Microsoft Update. I have also tried to download the drivers for the T420's wireless network card:

Intel(R) Centrino(R) Advanced-N 6205

Connecting the T420 to a wired connection makes it go at the 1MB/s that it should do with wireless connection too.

I am really clueless about what to do with this situation.

What kind of router do you have? Have you tested other machines/wireless cards with the same router? Are they also 11n cards? What about trying the machine with different routers (i.e., take the t420 to a coffee shop and see if the same thing happens there). Take a look in your router settings. In particular see if enabling/disabling 11n functionality (if it has it) helps at all.

Oh, and you might want to check if there are any wireless powersaving options on the machine itself.
