I did not uninstall network manager.  I managed to get WICD to connect.  It
was slow also but maybe because of conflict.  Does WICD support VPN's?

I have some other data.  The speedtest.net test on my netbook comes in the
same as on the HP unit in question, but it works more reliably.  I still
have W8 on the HP and I get the same reading from speedtest.net.  I have
not used W8 on the HP often enough to know if it is more or less reliable.

The other W8 machine is often connected to a server in the US for work
purposes and the speed test showed a US location although the VPN was
disconnected.  I deleted cookies and it remained in the US, where I got the
better test results, although the first one was in the same .65 download
range.

I have already disabled 11n as follows:

sudo rmmod iwlwif
sudo modprobe iwlwifi 11n_disable=1

Would your method be better?  Not sure how to make that file-  can you post
instructions?

thanks
