Title:
n-m fails to correctly set T-Mobile DNS and default route, dhclient
repairs it
Status in “network-manager” package in Ubuntu:
Confirmed
Bug description:
Network Manager when using a T-mobile Rocket USB HSPA stick, fails to
set the DNS and default route correctly, resulting in unusable
network. I am using an Oneiric Beta 2 boot cd to rule out existing
settings causing the issue.
Here is the NetworkManager provided settings. You can see that the
local IP address is placed at front of resolv.conf and that the DHCP
provided default router is missing and a device route used instead for
the default route, which does not work.
