Got my mate's openbox with me as his gift's ran out and I said I'd sort it as he's not particularly good with these things. No problem I thought, I'll just follow the guide here as I've never seen one in person before. Except my line is showing as "offline" and I have no idea how to solve it. It's an N line, and I can see on my panel that it's active, and it works on other boxes in the house (it's multiroom, and I also made sure to remove it from the other boxes just to make sure that wasn't the problem). Can anybody help me? As I say I followed guides on how to add the line but I can't stop it from showing as offline.
