Hi,<br>
<br>
in case NM and ppp configure options look normal my suggestion for<br>
narrowing down the problem would be to use the pppd command line<br>
from the NetworkManager log without the "plugin<br>
/usr/lib/pppd/2.4.5/nm-pppd-plugin.so" part and check if pppd also times out<br>
when you start it manually. If it does try adding the options read from<br>
/etc/ppp/peers/gprs one after another. A common problem with some TS 27.060<br>
IP relay implementations in mobiles is the lack of proper VJ/CCP support.<br>
Please try adding novj noccp first.<br>
<br>
Regards,<br>
Reinhard<br>
