I'm not going to pretend to be an expert in ethernet cables however, I understand that a Cat 7 cable has the capability of delivering higher speeds than a Cat 6 cable, which has a capability of delivering higher speeds than a Cat 5 cable etc. Accordingly, this Cat 6 cable is fairly close to the top of the range, in terms of speed delivery (except for Cat 8, which I can't comment on at all). For internet purposes, the speed capability of any of the aforementioned cables probably vastly exceeds the speeds that can be delivered to their home by their broadband supplier. From that perspective, it therefore probably doesn't matter which cable you choose, but with internet speeds improving all of the time, it's probably best to go with the highest category you can afford. For example, with BT now delivering (in theory) full fibre broadband with speeds up to 900Mb/s, all Cat 5 cables and above should be able to deliver these kinds of speed. However, if internet speeds get any faster, some Cat 5 cables might become a limiting factor, as they can only deliver speeds up to 1 Gb/s. Cat 6 and above cables shouldn't become obsolete in this manner for a very long time. Turning to how the internet is delivered in the typical home, I suspect that Wi-Fi will remain the most common approach for the foreseeable future. However, what I suspect a lot of people don't realise is just how much that can limit the speed they achieve, whether through distance or other electrical interference. As such, I ran a series of internet speed tests, both over Wi-Fi and with this cable. Over Wi-Fi, my average download/upload speeds were 28.2Mb/s and 6.98Mb/s respectively. With this ethernet cable, that increased significantly to 53.62Mb/s and 10.39Mb/s respectively i.e. it virtually doubled my speed! The length of this cable is 25 metres and whilst I thought that would be long enough to connect even the furthest away device in my house, it turned out that it was only able to stretch from the router into the lounge. That's not because my house is massive (it isn't) but more to do with the fact that in order to get a neat finish, you have to go up and down and over various objects (e.g. doorframes) in order to get it to the desired location. Accordingly, make sure you measure very carefully before purchasing any cable, as you you easily find out that what you have is too short.
