Hi,

I'm under the impression that one of my LAN-SSH connections is working
poorly. When I SSH from a wired desktop machine (generic) to a
Wi-Fi-ed notebook (ThinkPadX220) things take irregular and seemingly
excessive amounts of time to happen (you type and the text appears a
moment later, etc.). This is just a
desktop→cable→router→Wi-Fi→notebook (W)LAN scheme.
Issue appears also logging from notebook to desktop.

Also I've been having some apparent poor performance in simple
web-navigation with that notebook (always through Wi-Fi), so, I'm
suspecting: maybe some issue with the firmware-iwlwifi?

$ lspci | grep "Network controller"
03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205
[Taylor Peak] (rev 34)

Both machines run Debian testing (updated).

What could I do to check/test the health/performance of the connection
in order to diagnose if there's effectively a problem?

Thanks a lot!
