Changing to a new Router the Linn DS will no longer connect
Some new Routers, such as TalkTalk, have network sockets that only support a high speed network (1000-BaseT). The Linn DS will only has has the network components that support 100-BaseT connection.
Your PC laptop will work on this Router socket as your PC will support 10/100/1000-BaeT connections. The simple solution or test is to add a low-cost network switch that supports (10/100/1000 Base-T connections) such as a Netgear GS205
Fritzboz not seeing the Linn DS/DSM products
Fritzbox reported having issues with Apple broadcasts and losing connections. This appear to be due to the Fritzbox monitoring the LAN sockets and shutting down anything that is not active and going into Green (power saving) mode. The manufacturer has reported the following fix: 1. Open a web browser and enter "fritz.box" into the address bar to open the router's configuration page 2. Go in to advanced/expert mode, rather than Wizard mode 3. Go to the "System > Energy Monitor > Settings" pane 4. Set the LAN port that the DS is plugged into to be "always active" 5. Click the "Apply" button
