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
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
