Tethering on a Laptop - "Failed to start Mobile Internet"

Hi, I've got a Laptop that will not tether.

 

Firstly, I've tried 3 different Blackberries all from the same service provider. All 3 of these devices are able to tether on other laptops/desktops.

 

I try to tether on this one laptop (Dell Vostro, not that it matters, I have other Vostro's and other Dells that work fine...) and it immediatly gives the error:

 

Failed to start Mobile Internet

There was a connection error.

 

I know I can tether with the Blackberry, I know the proper ISP settings... Any ideas? It fails immediatly.

Re: Tethering on a Laptop - "Failed to start Mobile Internet"

Hello Strider,

I like you to check out in device manager if you have under ports two ones named: RIM Virtual Serial Port v2(COMXX) where XX in my case is COM10 and COM11 but would be different in your case.

 

If you don't have these 2 virtual ports then somebody installed the DTM not under the 'Administrator' account. DTM will install also under a user account  and works OK except not for tethering which needs a standard modem driver via the 2 virtual ports.

 

I suggest to do a clean uninstall (see link) 

http://btsc.webapps.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalId=KB02206

under the current user account and then re-install DTM 610_b034_multilanguage.exe  under an admin account and give the user a link to the DTM (it is probably still on his/her desktop).

 

If  this suggestion helped, please, click the blue 'like button' and select the 'resolved' option. Thank you, matt.

Re: Tethering on a Laptop - "Failed to start Mobile Internet"

Thanks for the advice, however I resolved it yesterday.

 

Oddly enough, I ran some windows updates and something in there fixed it up. Your suggestions sounded sound though. I had already done a complete reinstall of the DM to no avail. DM was installed using an administrator account every time.

 

Thanks!
