Quick update to say the DW58321e is now working inside my 7320 2in1.  Only two antennas required.  Just the Main and the opposing Aux antenna is connected.  Had a bit of an issue turning the cellular data on once it was up and running.  Tried the dell cus kit and still hit an error telling me the card wasn't qualified.  Found a solution though.  And it is simply to disable the device while you initialise the cus kit.  And then re-enable the device while it's running to be able to click the 'Enable Radio' button.  Worked like a charm. Quick speed test and get a nice 60 DL and 20 UL on an EE 4gee SIM
Hi  I bought a year old 7320 and want to add WWAN.  Checked the various manuals and guides which gave me 2 compatible options of which I opted for the DW 5821e WWAN card as it has better transfer rate.  There appears to be two antenna wires ready to attach inside the laptop as described in the installations guides so all seems good.  However  all the online tutorials refer to the other option of WWAN card. The other one has 2 antenna terminals, the DW5821e has 4.  A Main and 3 Aux.  My question is simply do I need to have all 4 terminals coonnected (and therefore I'm 2 wires short) or do I just connect to the main and one to an Aux for it to work? Any help or advice from others that may have experienced similar would be much appreciated....
