My Acer One 8.9 "" notebook spontaneously has an inability to connect to a 3G network stating the "WWAN is missing or disabled". This happened sometime after 4/16 - as according to the diagnostic that it the last time there was activity on the Qualcom modem. And according to the Modems section it is "not responding". I have only had this unit 3 weeks. Most vexing is this is the SECOND acer that has done this to me - my first acer did the same thing at about 3 weeks - and I exchanged it. I seems the WWAN dies in the burn in period. I have reinstalled the 3G drivers - no help. I am not a very technically proficient with computers and not sure what else to do? Suggestions. I ready to return this one too!
