My C-7 worked fine till last upgrade 2.2.6.13*
Now, whatever I do, hub self-assignees IP address and cannot connect to internet.

I try to reset DHCP, reset device with button, downgrade to previous versions, switch cables with C-5, which is working fine (I didn’t upgrade it), disable all apps and drivers. Nothing help.

Could anybody help with this?
Almost 3 weeks pass and nobody even replied to me.

Support forwarded my request to tech support, but they also completely silent.

I would expect better support for such good product...
