This Article Applies to: 

Note: This article is applied in the following situation: you can connect to the wireless of Archer MR200, but none of your devices can get internet access and you might see the following icon on your computer.

Preparation: log in the web interface (click here to see how to do this) ----check the Ip address in the Internet window on Status page under Advanced.

If the Ip address is not, then refer to this FAQ.

If the Ip address is, it means the router is not connected to the internet yet. The reason can be that SIM card’s supporting BAND is not the same with this router’s or the router’s self-inserted APN is different from ISP’s etc.( ISP stands for the Internet Service Provider)


1: Sim card’s supporting band is not the same with the router’s

The phenomenon can be that the SIM card is not recognized by the router at all (you will see that the ‘profile Name’ is ‘none’)

Solution: Check with your 3G service provider to make sure that your SIM card supports the Network Type which Archer MR200 supports. You may check the details of Network Type on our Official Web Site. Also, it’s working properly when it’s inserted to your phone.

2. The SIM Card is disabled by PIN code.

Solution: contact your Internet Service Provider to get PIN Code of your Sim card and fill in that Code into TP-Link router.

3: The router’s self-inserted APN is different from ISP’s

APN info is inserted in the router before you input your SIM card. Sometimes, your ISP may change their APN without our notice.

Solution: create a connection profile by yourself.

The following info will be needed to create a profile: ‘APN type’ and ‘APN’ (from ISP), ‘profile list’ ‘profile name’ (this can be something you like); ’PDP type’ (ipv4 or ipv6) (decided by the ISP); ‘username’ and ‘password’ ‘Authentication type’ (optional and decided by ISP)

To create a profile:

Go to ‘advanced’--’Network’---‘Internet’---’profile management’---’create’.

After you do the above troubleshooting, if still no internet access, then you may update the firmware to the latest one for a try refers to this FAQ.
