I have a new Surface 3 4G LTE with Windows 10 pre-installed (purchased 28/10/15 from UK Microsoft Store). It appears to be working smoothly, including the mobile broadband, but from day one Event Viewer has been showing a dozen or so DriverFrameworks-UserMode "critical" events per day, both Event ID 10110 "A problem has occurred with one or more user-mode drivers..." and 10111 "The device Surface IA7260 Firmware Update... is offline due to a user-mode driver crash. Windows will attempt to restart the driver 5 more times..." There's also an associated Application Error ID 1000 for faulting WUDFHost.exe (faulting module ntdll.dll). Despite this, the IA7260 Firmware Update appears in Device Manager (as a hidden device) connected and working under the Surface 3 Modem Device . Presumably the driver is eventually starting so all is more or less well, but it is rather alarming to see the log filling with "critical" errors, and of course the Reliability History rating is pretty much rock bottom. The other (likely) side effect is that Update History shows numerous instances of installing "System Firmware Update - 18/09/2015" - supposedly successfully in each case - presumably this update contains the IA7260 firmware update.
Does anyone else see this issue on the 4G LTE model? And/or any suggestions for remedy? Thanks!
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
OK. Used LTE connection in not moving environment for 2:45 hours non stop. Signal was not too strong 1-3 bars only, but connection was stable. Used internet service in different modes (surfing, download, chat, etc). Not even single disconnection !
So, it looks like issue happens only in moving environment.
Use LTE at home and see if it repro's. That MAY determine if the issue occurs when switching between cell towers etc. Getting Microsoft to test outside a lab environment may be next to impossible, but this MAY help convince them.. especially if you can't recreate while at home using LTE.
Question: if you use LTE in a non moving environment, not on the train, perhaps at home, can you duplicate these disconnect issues?
At home I am using wifi and no issue. I need to check LTE for couple of hour work, but it will be different conditions for reproducing the case. Agree?

Hi Barb, I imply under "normal work" - expected behavior of computer device in Testing terminology. Critical issues like "no connection to network" or "freezing screen", which require reboot, I classify as not expected, aka not "normal".
Actually, I encounter only with "no connection" issue (in SIM card adaptor), which cannot be recovered any other way than reboot. Sometimes "no connection" happens after 20 min after turning on LTE connection, sometimes after 30-45, but usually I have to reboot sometimes up to 3 time during my 1 hour trip. Problem is never happens, when I am using WiFi connection, but to be fair, wifi is used in another conditions.
Above issue is different than just changing signal of broadband provider during move. I am observing such behavior as well (in intervals between reboots), signal level is changing, sometimes to 0, but it is very quick jumping back, without significant impact to open applications and does not require my interventon. I consider such behavior as expected as well.
I am really surprised, if nobody else encounter with "no connection" issue with LTE. In terms of QA it severity 0 issue. How can we get official support case opened for it?
