3G/4G USB Wireless Dongle Failover

I want to use a 3G Wireless USB dongle for my failover Internet connection on my Draytek Vigor 2820

Question: Once the failover kicks in, (3G USB) will the Internet connection be provided through the ethernet cables already plugged into the router and the PC’s? Or will the PC's require a wi-fi card for a wireless connection to the 3G dongle?

Question 1 = Yes.

Question 2 is irrelevant. ALL PC's require a WiFi adapter to talk wirelessly with a WiFi router; you cannot make a wireless connection to a 3G USB dongle using a WiFi adapter.

Darr247 - Thanks

The router in question is a Draytek Vigor 2820 and is not wireless .

My question is that once the 3G dongle is plugged into this router, how will the PC's gain internet access ?
Basically the Draytek router is plugged into a 24 Port switch and then patched in a patch panel to provide an Internet connection to 7 PC's. If the internet goes down will the 3G USB wireless dongle provide an internet though the patch panel cabling through to the PC's ?

Or will the PC's require a wireless card ?

Gary - Thanks, very clear information, so at least I know now that the connection will be fed through the cables.

Will the APN Name vary from different providers ?

As I recall, the Drayteks can be configured for either load-sharing or failover on the multi-WAN sources. So it's up to the Draytek how the PCs gain internet access... plugging in the dongle, per se, should not affect that.
Nothing will change as far your connected computers are concerned.
I fail to see how "Question 1 = Yes" is at all unclear, by the way.
He gave two scenario's - so yes is a bit confusing ;o)
There is only 1 scenario. A 3G/4G dongle configured as failover in a Draytek.

A WiFi adapter talking to a 3G/4G dongle is simply an incorrect premise on how the 2 very different technologies function.

Very clear too the point answer.
