Well, at first I have 1Gbps connection for like 3.5 yeard already with rarely getting down, maybe cause of heavy rains and so on (ISP before current handled even that!!!! ) and when it was critical and not fixed within few hours it was router power supply (2 times - be sure to buy not cheap and powerfull, something like 10W = 2A, 5V) and if not that I will just go with laptop to any cafe with wifi or so, so I think it's solved for me. Any critics ?
