My Cf31 didn't come with a mobile broadband WAN card. No biggie. The one the seller normally had was an Ericsson job. What are your views on the best 3g/4g WAN setup for a CF31? It needs to be something that works in Australia with our Telco's here (Telstra, Optus and Vodafone tier-1 mobile network operators). BTW I popped into the BIOS today and saw the unit has logged just over 2000 hrs. The condition is basically like new. ;-) back to topic. I see there's a thing called Gobi 2000 which appears to have been an original OEM option, and the other one that pops up a lot is the Ericsson F5521GW but I read in another thread it has to have vendor-specific firmware (!). Does a Cf31 by default have antenna cabling for a WAN (3g and/or 4g) like it probably has for wi-fi?
