Now let's take a look at the similarities and differences between Cisco routers and other computers on the Interconnect Network. Similar to other computers, a vro also has memory, operating systems, configurations, and operating systems in the Cisco vrocisco. It is called InternetworkOperatingSystem or IOS, all rights reserved by Cisco ). Similar to other computers, a router also has a boot process for load

sharing, link backup and other network routing information exchange and so on routers have the function. In order to connect with various types of network, the router interface type is very rich, and the layer three switch is generally only the same type of LAN interface, very simple.3. Performance does not reflect the same. Technically speaking, routers and lay

The terminal connects to a 3G/4G router and uses a 3G/4G network to access the Internet.Troubleshoot the problem as follows:A vro can provide multiple terminals to share the internet. When a terminal on the intranet downloads, games, movies, and other large-volume internet access applications, other users may experience slow Internet access.You can temporarily disconnect all other terminals to ensure that only one terminal

Problem DescriptionWhen you use a vro to access the Internet, the network speed is slow or unstable, and packet loss occurs on the ping Internet, as shown in the figure below:Ping packet loss is generally caused by physical connection quality or line congestion. We will analyze and troubleshoot the factors that are most likely to cause such problems. Please follow these steps to check:Troubleshooting1Reduce
