I've been having trouble upgrading the DCS-942LB1 from 2.00_4017 to 2.10.07.
I have two of these devices (both rev.B) and encounter the same problems on both.
The 2.00_4017 firmware is stable, but when I upgrade to 2.10, the cameras have trouble maintaining a wireless network connection. Most notably, when you perform a soft reboot (i.e. select "reboot" from the web interface, or schedule a reboot), the device does not connect to the network. A "hard" reboot (i.e. unplugging the device) usually solves this issue. If I reset my router, the cameras do not connect. Both continue to show a steady green LED although they are not connected to the network. The camera continues to record.
This problem does not happen 100% the time, but I would estimate that it occurs 4 out of 5 soft reboots. Again, this is happening on both of my DCS-942LB cameras, so it's unlikely to be a hardware issue.
EDIT: Some further notes.
I upgraded the firmware through the Canadian mydlink.com website (https://ca.mydlink.com/device). The cameras were bought in Canada.
The MyDlink website urged me to upgrade to 2.10, but if I look at the support site for the DCS-942L camera (http://support.dlink.com/ProductInfo.aspx?m=DCS-942L), the latest firmware is 2.00.4017.
I have also tried downloading the "World-wide" firmware file and flashing using the web interface, but have the same problems (again, on both cameras).

I use a Netgear Nighthawk R7000 router, but the problem also occurs with my previous router which is a Linksys WRT310N.
Thanks for any help you can give me,
