unable to browse with 3g when connected to LAN

Hi Experts, i have an Acer TM 5730 notebook with built in 3g using a vodacom sim card. i am using vodafone mobile connect lite to connect. At work i am connect to a lan with a dsl internet connection and use this connection most of the times. Sometimes what might happen is the DSL internet at work might go down an i connect via my 3G then. But i am unable to browse. i have no proxy configured. I still need to be on the lan as i want to access some shares. It looks like all the traffic wants to route via the lan connection opposed to the 3G. How do i fix this, i have seen this on so many pc's. The only way you can get it working is if you unplug the lan cable, then only does the internet work. I do remember some years ago that these 3G cards setup a dial up connection and it would work but now a days it adds itself as a local area network connection. I think this is where the issue arrises

Help please

Verizon cards I know will connect, and then go dormant, then disconnect, if it detects a wired connection.

Perfectly normal for you, to have to unplug the LAN cable to connect this way...

Might be able to disable dhcp media sensing, but that's kind of a stretch, and would lose a built in benefit.....

Thank you. I was pleased to help. ... Thinkpads_User
