D-link dwr-921 can not connect to internet

Here is the manual:
http://files.dlink.com.au/Products/DWR-113/Manuals/DWR-113_A1_Manual_v1.01(WW).pdf

You should check you network service for the Apn they use. You may have to insert the apn on the tablet to get the data

I do have the same problem. All works fine except it stays "disconnected" and no way to change that.
Also I found no way to put or change the number to be dialled in the DWR-730 to connect to a service. Normally it needs to dial *99# for the operator I am using. I guess our problem is only that.
Who from Dlink can tell us how to access the modems dial string?

You can contact customer care to get the procedure for datacard activation for your sim.

You'll need to configure the Internet Access Point Name (APN) of Airtel into one profile of your data card, the dial number for a cellular modem (data card) commonly is *99#, the APN data of Airtel could be requested to the following link: https://www.airtelusainc.com/Contactus.aspx , but before a simple test you can do to check if your data card can handle the Airtel SIM card is inserting it into the data card and launch its connection manager, if the software shows invalid SIM or similar message, it means your data card is locked or tied to Beetel SIM cards, but if it shows Airtel header and a good signal level you'll only have to input the mentioned data above.

This configuration is working perfectly using ZT321, Baizhao 8928 and IPhone Clone A380 and probably will work using other China Phones.
If your SIM card is previously activated using other phones specially those phones supported by Globe and Smart, no need to activate your SIM. This is also valid for postpaid users since SIM cards are pre-activated for MMS, GPRS and other services.
But if your SIM is not yet activated or never been used for MMS and GPRS, you need to activate your SIM before you can use MMS and GPRS services.
For Smart SIM, you can use your China Phones to activate MMS and GPRS by simply sending/texting MMS ON / GPRS ON to 333 (I don?t know if this number is still valid). No need to download the configuration for Smart. Just use the configuration I?ve given.
For Globe SIM, this is a little bit harder and need some workaround. I tried to call Globe Customer Service but they cannot activate your SIM manually on their system and the only way to activate it is by downloading the configuration thru text or by asking them to send the configuration. But since China Phones are not yet supported by any Service Provider, what you can do is to active MMS and GPRS using another phone. Monitor until your SIM is activated then transfer your SIM in your China Phone and enjoy surfing and sending MMS.
In another forum, they said you can try using configuration for SE p900. I?ve never tried this but if this really works, well and good for China Phone fanatics.
