I’ve tried this morning the following:

Power off the E5776.

Disconnect the USB cable.

Power up the E5776.

Attach a WLAN client and start pinging an address on the Internet over the WLAN 
link to the E5776 and onwards over its LTE link to my network operator.

Connect the E5776 to my Linux box and allow usb_modeswitch to run.

Bring up the wwan0 connection on the Linux box and run dhclient to obtain an IP.

Ping an address on the Internet from the Linux box over the wwan0 connection.


At no point after the original WLAN client is attached, does it ever lose its
connection or stop receiving ping replies. The wwan0 interface likewise works
as expected.

So it seems that this device at least  (E776s-32) can work with both types of
client simultaneously.

Cheers
