After some more testing with 3.14-rc8 I can confirm that the situation is just a tiny bit better than in the repository kernel:
* associating to the cellphone accesspoint does not always work and the syslog shows several attempts until it works if it works
* if the connection is there, it is unstable and sometimes disconnects with traffic
* packet loss and ping times are bad (see belowresults for pinging my personal homepage (hosted in switzerland) via my cellphone accesspoint

pinging from the computer with the 3.14-rc8 kernel and the WN8200ND hardware: ping-8192cu.txt
--- www.peterschuel ler.com ping statistics --- 496.532/ 2018.405/ 510.937 ms, pipe 3
28 packets transmitted, 28 received, 0% packet loss, time 27045ms
rtt min/avg/max/mdev = 157.014/
pinging from my laptop (centrino ultimate-n 6300 wifi card):
--- www.peterschuel ler.com ping statistics --- 867.568/ 4077.452/ 835.474 ms, pipe 5
29 packets transmitted, 21 received, 27% packet loss, time 28101ms
rtt min/avg/max/mdev = 367.968/
So the average roundtrip is actually better with the 8192cu but the deviation is greater and the packet loss is 27% compared to 0%.
