2. Check whether the line between the network cable and the router is loose.
3. If all the above are normal, it is caused by the instability of the operator's network itself, and it will get better after a while. If you are not at ease, you can call customer service for consultation.
(1) Routers are devices that connect local area networks and wide area networks in the Internet. It will automatically select and set the route according to the channel conditions, and send signals in turn by the best path. The main difference between routing and switch is that switching takes place at the second layer (data link layer) of OSI reference model, while routing takes place at the third layer, namely network layer. This difference determines that routers and switches need to use different control information when moving information, so they realize their respective functions in different ways.
(2) Routers, also known as gateway devices, are used to connect multiple logically separated networks. The so-called logical network represents a single network or subnet. When data is transmitted from one subnet to another, it can be done through the routing function of the router. Therefore, the router has the function of judging the network address and selecting the IP path. It can establish flexible connection in multi-network interconnection environment, and can connect all kinds of subnets with completely different data grouping and media access methods. The router only accepts information from the source station or other routers, and belongs to an interconnected device in the network layer.
