AirCard 785S errors / hangs (EU version - AC785-100EUS)

Hi,

I have a AirCard 785S (the unlocked EU version SKU: AC785-100EUS) which has been working fine for about 3 months until it recently started to develop some odd behaviours / faults:

(1) When powering on, it will sometimes / often not progress past the blue Netgear AirCard boot up flash screen. Booting seems more reliable when plugged in to the wall charger.

(2) Even when the AirCard does successfully boot, it will occasionally / often fall back to the blue screen.

(3) The occurrence of these behaviours appears unrelated to the battery charge level

(4) A separate fault is now occurring (developed in the last 7 days) where the unit will disconnect from the internet and the screen will show that there is no SIM card inserted (even though there is and the unit hasn't been dropped or bounced). Again, this appears intermittently and doesn't appear to be related to battery level, but doesn't appear to occur when plugged into the wall charge.

Any ideas out there?

Cheers,

Yorkshire_Boy.
