Hi Guys. Currently having an issue with my Router/Switch setup and not sure why. I have a Netgear WNDR3700v2 router which is located downstairs and I've cabled my house so that a ethernet point upstairs in my home office. In my home office i have 3 devices connected to a TP Link SG105 (Metal) 5 port switch. An iMac,PS4 and Sky+HD box. Now, over the last few months and even more so lately (once or twice a day) the connection via ethernet will drop across all 3 devices, but WiFi works fine, and the only why to get an internet connection again is to turn off either the router or switch at the wall and then back on. When the connection does drop the Mac tells me it has a self assigned IP Address and cannot connect to the internet, so I'm assuming its the same for the other 2? I have gone into my router settings and given the 3 ethernet devices reserved IP's but it still drops connection. Is this a dodgy switch or router, or is there a fix? Thanks.
