I have next to no experience with any of these, and therefore can't 
offer any advice specific to these apps.

If switching users is the cause of the problem, why don't you just 
use /etc/network/interfaces? If the laptop tends to stay within the 
same network, this would remove any need to configure anything 
(unless you use a strange setup like my university does).

If the laptop frequently changes networks, that in itself may cause 
some problems if the driver isn't well-written. It might help to 
unload (rmmod) and load (modprobe) it.

I haven't been able to use NM since I need more than one network 
interface to be active at a time (i.e. both ethernet and wireless). 
Since I've always used /etc/network/interfaces, this has never really 
bothered me...

The Idea behind NM also has the problem that one needs to log in 
before a network connection can be established (unless something 
drastically changed). This is a problem on my Desktop, which I tend 
to start and afterwards use/manage remotely...
