Apologies for writing in English.

My router doesn't work (Speedport Pro Plus). Either the green lights keep blinking, or I have the 4 yellow lights.

I have tried everything, full reset, router restart, unplugging/plugging back on, but nothing. It's Friday night and I need to work this weekend but am stuck now.

I'm also unable to access the speedport online because my laptop doesn't have an Ethernet entrance and, obviously, the wi-fi doesn't work. 

Please help as soon as possible.

Thank you.
