Automatically obtain the address through wireless route settings

The address is automatically obtained through wireless route settings. This is not a simple problem, and you are new to it. Yesterday I encountered a strange problem. Just help friends get a brand new wireless router, the model is tplink tl-wr541g, is also a lot of award wireless router, wan port connected to Shanghai wired cable modem, why can't the wan port of a wireless route automatically obtain an IP address? In fact, the wan port is always being updated, and there is no information, not just no address ).

First, no matter how the wireless route is connected, the lan port and wireless end of the wireless router are good. You can use 192.168.1.1 to access the network segment 192.168.1.X of the wireless route normally. The wan Port page is good. Please read it down. The problem is that the wan port of the wireless router is connected to a cable modem, And the wan port status update is always displayed on the webpage management page. is the status of the wan port automatically refreshed once? Configuring the wan port of a wireless route is a dynamic IP address. It must be correct. Like setting a wired router, a wired route can, but a wireless route cannot obtain an IP address.

In order to confirm that the wireless route settings for wired connections are not a cat problem, two wired routers, tplink r410 and dlink di504, are used as common routers, you can set the wan port to a dynamic ip address. The network is connected, the wan port of the wired router is normal, and all the ip gateways are available.

To identify the problem of wired-to-Wireless route settings, connect the wan port of the wireless route to the lan port of the wired router, and then connect the wired router to the wired-to-cable modem, the wan port of the wireless route is connected, and the IP address and gateway of the wan port come out. The IP address is the IP address of 192.168.0.X allocated by the wired route, all computers connected to the wireless route can access the Internet. This indicates that the wan port of the wireless router is good, so you can understand the problem even more. All network devices are good. Why cannot I automatically obtain an IP address?

What is the difference between a wired or wireless router? I tried wireless routers to clone the mac address of the desktop, and turned on the wireless host camouflage function. I restarted the wireless router and cable modem many times and restored the factory settings. The search engine searched and found many articles about the normal use of wireless routing through wired connections. What is the problem of wired-to-Wireless route settings?

I would like to ask the high-end engineers for the reasons for the problem of wired-to-Wireless route settings. Thank you very much! Thank you, too! Question added: you can connect to the adsl cat for pppoe dialing. Thank you for your enthusiastic answers from the friends on the second floor. Now we have used adsl for our friends. Forget it. It may be an unsolved device compatibility problem.
◆ Is it successful to directly connect the computer to a wired connection? Normal
◆ Disable DHCP and check whether DHCP can be connected. I have never tried it. I cannot try it now.
◆ Has the route refresh the latest ROM? Generally, bugs can be flushed. For example, my path is disconnected from the past two to three hours. No brush, but the firmware is 06 years old and there should be no problem.

What do you mean? Because you cannot view your computer on your own, it is not very clear, but to make it easy for your friends to access the Internet, you can disable the DHCP function of the route, turn the route into a Wireless AP, and then enable local access. Shanghai wire connect supports two public IP addresses. Generally, if two computers have a wire connection, wireless routing is not difficult to set up. The difference is that the router firewall may be useless when exposed to the public network.) You do not need to write too many words, just answer these questions and I will try again later.
