Windows OS - Cannot Access Internet After Configuration
Problem Description:
You have set up the wireless router and successfully connected to your wireless network, but you can't access the Internet:
Step 1:
Please check if the wireless network connection of your computer is set to obtain an IP address automatically, and obtain DNS server address automatically. If you don't know how to configure this, please click here.
Step 2:
Press Windows key 
and R key on the keyboard at the same time to open the Run application, type ‘CMD’ and click OK. Type ‘ipconfig –all’ in the coming window and press Enter.
If your IP is 169.254.xxx.xxx, you will need to attempt to renew your address. Please type in ‘ipconfig –renew’ to get IP address again. If you still do not get a proper IP address, please make sure you have enabled the DHCP function on your router. You can login http://tplinklogin.net (or http://192.168.0.1) With a computer or tablet that has successfully connected to the router.
Step 3:
To log in to the web management page of the router, open the web browser and input http://tplinkwifi.net:
Type the log in username and password and click ok. The default username and password are both admin.
Step 4:
After you log in, check the WAN part on the Status page. See if an IP address is listed. If so, that means the router is successfully configured and connected to the Internet:
If there is no IP address listed, please check the physical connection or call your service provider to check the line.
Step 5:
If there is IP address on the WAN part on the Status page, test the connect by pinging a public IP address (like 8.8.8.8). If this fails, please release/renew the WAN IP address. If successful, please check if you can browse to any website. If you can’t, you may need to change your DNS servers. Please go to DHCP->DHCP Settings and type in 8.8.8.8 for the primary and 8.8.4.4 for the secondary then, click Save.
Step 6:
Reboot the router.
After rebooting the router, please try the Internet again. If you still can not access the internet, please call TP-Link support for further help.
Restarting the router may sound too cliche, but it actually helps(sometimes a lot), by clearing the caches and associated software/network problems. Other potential causes can be broken cables or disrupted services.
Hi, is it a MUST to set up my PC to obtain an IP address automatically from the router before it is allowed to access the internet on MR400?
We got a MR400 router for our site office. As the PC is connected to SCADA system and it is required to use a static IP. Our MR400 is set up exactly like the print screen in Step 5 above.
Our PC is manually set up at 192.168.0.104. The router just won't allow the PC to access to the internet. Is there a workaround solution?
Any pointers will be greatly appreciated!
Is there any way to change ip over time?
