TL-WR720N and HuaWei dongles

TL-WR720N was bought in China at about 120 RMB

The first thing to configure is to connect UTP to TL-WR720N

There are three modes router, 3G , AP

1. Safetest mode is to put to router mode
connect UTP to the LAN port (again avoid LAN/WAN port)

run a browser to conect via http://192.168.1.253

2. set up the wifi option under 无线设置
put a wifi password
Check the wifi server working ok or not

3. set to 3G mode and remove the UTP and connect via wifi

4. Set up the 3G

For all Singapore telco , turn of China telco and maually set

Few setting you require

I. Dial codes
there are three options
a. *99***1#
b. *99#
c. *777#

The first one a. is to one work with M1 unlimited dial up prepaid dial up plan
as given by staff at M1 paradgon shopping center

The second is the code given by hot line

II. APN is sunsurf

III. userid is 65

IV. password user123 but we used 65 again

So all in all, the setting work is
dial code *9***1#
APN sunsurf
userid 65
password 65

A. Dongle

There are various dongles

the list are the compatible list

看起来这华为型号有在

》TL-WR720N兼容3G上网卡列表

http://www.tp-link.cn/download/list/TL-WR720N/

A. I have tried with 3556-Z

Z refer to ZTE

and it failed badly

B. The staff at paradgon has tested latest E303 and it work (even though it is not in list)

C. We have another E153 and it is in the list and works

Last but not least is the sequence of connection (simultate manually)

1. Under TP configuration and status menu, TP will try to recognize the dongle

some of the model may need .bin to allow to be recognize

when recognize

the configuration status flash few times

the confirm  is when 

识别成功

and the bar even show a colour code bar on the signal strength

Then it will try to dial

(If not need to configure to auto dial or connect under one of menu)

so part I,II,III, IV play a part

If connected then there will be ip address and DNS show 

If not please check setting and power on/off router

so with the right dongle, just need to put the SIM card and it will auto connect to Internet
