ADSL automatic Failover to 3g and automatic revert

[HaGolem]

Hi All,
Background, small office 2 floors (working repeater on top floor but ADSL router is dead) - the ADSL wifi router recently died and we are looking to replace with something that can auto fail over to 3g and revert - there is no fiber in the area that we are aware of, but we might be moving to an area with fiber this year. I've spoken to a few shops who have routers that can take a 3g dongle but they all point me to my service provider to find a working dongle for my router.

Can anyone recommend something suitable for a small office (I'm so far interested in the ASUS DSL-ACT52U and DSL-N17U - but the ASUS supported dongle page does not list anything for vodacom south africa). Does anyone know of working router / dongle combos that are currently available - before I try phone vodacom 111 and hope their info is accurate.

If there is a post that already has current details please forgive my ignorance (first post) and just point me in the right direction

Draytek have some ADSL routers that also support 3G failover. This would probably be easiest from a "non-technical" point of view.

Alternatively, get a WAN router that supports OpenWRT (ADSL routers with the modem built-in, and OpenWRT support are few and far between), and has a USB port, and you can use an ADSL modem (DLink 2500U or equivalent) in bridge mode, a 3G modem plugged into the USB port (just make sure it is supported under Linux), and configure MultiWAN or MultiWAN3 to fail over between them.
