Does anyone know whether the Vodafone K4201 3G dongle is compatible with the Vigor 2830n? If so, what are the settings.

It is not shown on the DrayTek lists as being tested with the 2830n, but technical support says that it may be compatible.

I know am not answering your question but hopefully a vodafone user with the same model give you some info but i only posting only to let you know that 3 vodafone dongles are supported with one being similar
(taken from the menu of my 2830n "USB Application >> Modem Support List" with the latest firmware

Code:

Vodafone Vodafone K3520-Z Vodafone Vodafone K3565-Z Vodafone Vodafone K4605

Have you tried a google search if will bring anything with draytek ... anything draytek modem result in the search should work for the 2830 because their UI 7 firmwares are about the same

Thanks for your prompt response.

I'm aware of the models you've listed. The issue is that they are no longer sold by Vodafone. I've been supplied with a K4201, which seems to be their replacement for the earlier models. I've had a good trawl through the interweb and have tried all settings that I could find, but with no luck so far.

I may have to buy a secondhand version of an older model, but thought that I would persevere with the K4201 a little longer.

Tried a K4201 with the V2830 with the latest firmware (3.6.7). It doesn't work
I do have an old K3520 dongle which the V2830 should support, but the SIM card used by the K4201 is not suitable for the K3520.
