Internet password: Internet dialing password given by broadband company.
Confirm the password, that is, online password. Just enter a password repeatedly.
When installing broadband, the master should leave a note with broadband installation address, broadband account number, broadband password and broadband rate printed on it.
At all levels of the Internet, routers can be found everywhere. Access networks enable families and small businesses to connect to Internet service providers; The router in the enterprise network connects thousands of computers in the campus or enterprise; The router terminal system on the backbone network is usually not directly accessible. They connect ISP and enterprise network on long-distance backbone network.
The rapid development of Internet brings different challenges to backbone network, enterprise network and access network. Backbone requires routers to forward several links at high speed. Enterprise routers not only need a large number of ports and low prices, but also need simple and convenient configuration and QoS provision. Enterprise routers such as Feiyuxing provide SmartQoSIII.
Access Router An access router connects small business customers in a home or ISP. Access routers not only start to provide SLIP or PPP connections, but also start to provide virtual private network protocols, such as PPTP and IPSec.
These protocols should be able to run on every port. ADSL and other technologies will soon increase the available bandwidth of the home, which will further increase the burden of access routers. Due to these trends, access routers will support many heterogeneous and high-speed ports in the future, and can run various protocols on each port, while avoiding telephone switching networks.
Enterprise router Enterprise router or campus router is connected with many terminal systems, and its main goal is to realize as many endpoints as possible in the cheapest way, and further requires supporting different quality of service. Many existing enterprise networks are Ethernet segments connected by hubs or bridges. Although these devices are cheap, easy to install and require no configuration, they do not support service levels.
On the contrary, a network with routers can divide the machine into multiple conflict domains, so it can control the size of a network. In addition, the router also supports a certain level of service, at least allowing it to be divided into multiple priorities. However, each port of the router is expensive and needs a lot of configuration work to use.
Therefore, the success or failure of enterprise routers lies in whether they provide a large number of ports with low port cost, whether they are easy to configure and whether they support QoS. In addition, enterprise routers need to effectively support broadcast and multicast. Enterprise networks must also deal with various LAN technologies left over from history and support various protocols, including IP, IPX and Vine. They also support firewalls, packet filtering, numerous management and security policies, and VLAN.
Backbone Router Backbone router realizes the interconnection of enterprise networks. The requirements for it are speed and reliability, and the cost is secondary. Hardware reliability can be obtained by using technologies used in telephone switching networks, such as hot backup, dual power supply and dual data paths. These technologies are the standard of almost all backbone routers.
The main performance bottleneck of backbone IP routers is the time spent looking up routes in forwarding tables. When receiving a data packet, the input port looks up the destination address of the data packet in the forwarding table to determine its destination port. When the packet is short or the packet is to be sent to multiple destination ports, the cost of route lookup will inevitably increase.
Therefore, putting some frequently visited destination ports in the cache can improve the efficiency of route lookup. Whether it is an input buffer or an output buffer router, there is a bottleneck problem of route lookup. In addition to the performance bottleneck, the stability of the router is also a problem that is often ignored.

(1) Your screenshot should be the router settings page, where "Internet account" is the user name of the broadband you handle and "Internet password" is the password of the broadband.
(2) The user name and password of broadband are written on the payment receipt or invoice of broadband, and you can find out the invoice. If you lose your invoice, you can call customer service to get it back.
(3) Unicom Customer Service 100 10, Telecom Customer Service 10000, Mobile Broadband Customer Service 10050. If you do not handle the above three state-owned broadband, but private broadband such as Great Wall Broadband, please call the customer service number of the local Great Wall Broadband for consultation. Generally speaking, private broadband users.
