Enterprise networks differ significantly from home networks, and their complexity is self-evident. When setting up an enterprise network, various issues often arise. Below are solutions to common problems encountered during enterprise network deployment.
I. Router Configuration Is Completely Correct, but Some Functions Still Do Not Work.
1. If the router configuration is confirmed to be correct, the problem likely lies in the router’s software system. Upgrading the software system can resolve this, as router system software often has multiple versions, each supporting different features. The most probable cause for partial loss of router functionality is that the current software system version does not support certain features. Therefore, performing the corresponding software upgrade should solve the problem without incident.
2. This type of issue has a relatively significant impact on enterprise users but is easily overlooked by enterprise network administrators. Enterprise users who frequently use the network have many functional requirements; missing one or two commonly used functions can cause many unnecessary problems for the enterprise.
II. The Network Runs Normally When the Router Is First Powered On, but After Being Online for a While, Connections Frequently Drop. Restarting the Router Restores Connectivity, but Dropouts Persist.
1. The causes of this fault are relatively complex. It could be due to hardware problems, or because someone on the local area network frequently uses BT software to download files, severely impacting network speed and degrading network performance. However, in most cases, it is caused by improper settings.
2. BT downloads slow down network speed and cause dropouts. In a shared network, BT downloads are a major issue affecting network speed. So when encountering frequent online dropouts, users should first check whether someone on the LAN frequently uses BT software to download data.
3. Multiple DHCP servers cause IP address conflicts. When there are multiple DHCP servers on the network, IP address conflicts occur, leading to frequent, irregular disconnection problems. Disable all DHCP servers on the network and assign IP addresses manually.
4. Incorrect connection mode settings. In the router’s management interface, select the “WAN Port Settings” option under “Network Parameters” in the left menu. Choose the “Connect on Demand” option under “Corresponding Connection Mode” and set the “Auto-disconnect Wait Time” to “0 minutes,” so the router will not disconnect automatically.
5. Suffering from Trojan horse or virus attacks. Besides incorrect settings, this is another major cause of frequent network dropouts. If you suspect an attack by hackers or Trojans, first check whether all connected computers are infected with viruses or Trojans. Use legitimate antivirus software or Trojan removal tools to scan and clean the computers of viruses or Trojans before going online.
III. Unable to Browse Web Pages 鈥?Pages Do Not Open Normally, but Programs Like QQ Run Properly.
This situation involves a DNS resolution issue on the router. If the gateway is set as the DNS address, which is DNS Proxy and not the real DNS address, it may cause address resolution errors. Manually set the DNS server address on the router and the computer’s network card. Open the router settings interface, find the “WAN Port Parameters” field under “Network Parameters,” and then manually set the DNS server address below. Additionally, in the “DHCP Service” settings, you also need to manually set the DNS server and backup DNS server addresses, which should be obtained from your ISP provider.
IV. Unable to Access the Router Management Interface to Configure Shared Internet Access Settings on the Enterprise Broadband Router.
1. This is mainly due to a previously created connection error. If the router management interface was logged into before, users should first check the hardware connection between the broadband router and the computer, check if the indicator light on the router’s LAN port is normal, temporarily disable any firewall or real-time monitoring antivirus software installed on the computer, then set the local IP address to the same network segment as the broadband router, and set the gateway address to the router’s default IP address.
2. Generally, broadband routers provide a Web-based management method
