Internet suddenly stopped working, all downstream channels locked
About 4 days ago my Internet suddenly stopped working in the middle of the day. Im living in a house which consists of two flats and router is in the other one so I don't have constant access to it. I managed to get hold of my neighbour and he rebooted it and it still did not work. Today I managed to catch him again and did a factory router reset. Internet is still not working, this is what I see when checking network status in the router advanced settings: https://imgur.com/a/9jecv
Anything I can do without physical access to the router? Thank you in advance for any replies!
