Firmware 3.201_beta3

[modumb]

just want to draw attention to a serious regression I’ve noticed on the latest betas:

3.201beta2 - AR750S - instability issues

I have been using 3.201beta2 since it was posted on the server. Since then, the experience with my slate has been quite unreliable: My huawei e1752 usb modem sometimes stops working and does not always reconnect even after a full reboot of the slate The slate sometimes spontaneously reboots As a result, I have not had a single uptime longer than 18 hours since using the firmware - normally the slate is left running 24/7 and would have days or weeks of uninterrupted uptime on 3.105 I…

3.201beta2 - AR750S - instability issues

To continue the report… the 3g modem was never stable under beta2 as it is/was with 3.105. Unfortunately, under beta4 of 3.201 the modem is completely unusable. Starting each time from a clean firmware (no settings retained), I have not yet managed to make the USB modem work for longer than 20 minutes and then only for just one time (did not work after reboot or ever again). I have spent an hour trying every approach I could think of to make it work again only once but I cannot make it happen…

EDIT:

at least with beta 4 there is some information showing up in the logs:
