Hi Arnd,

we should take into account how good the wlan connection is.
This of course leads to tests on real hardware. I do have a vt6655.
Please have a look at the test results below. In a nutshell it is a very
bumpy connection you get with vt6655. You can have issues to connect on
every channel and data is coming in waves. So sometimes you will almost
not notice you have a wlan connection and then it takes very long to
load the next site. Ping times up to 80 seconds. Packet losses up to
40%. So I assume all users have gone away from this module as it is not
comfortable.

Do you think this helps you?

I do have two vt6656 hardware as well. Are you interested in tests?
I can do a patch to remove vt6655. Do you think it makes sense?

Thanks for your support.

Bye Philipp
