Model: TD-W9970  
Hardware Version: V1
Firmware Version: 0.9.1 2.5 v0025.0 Build 150917 Rel.56865n_CA

Hi, I have a TP-Link TC-W9970 DSL router. As my ISP decided to terminate ADSL 
connections because "nobody uses that anymore", I have to look elsewhere. 

 

I tought maybe my computer tablet or cell phone could be of some help. The 
tablet support broadband/cell connection, I have direct internet (no wi-fi 
needed). Then I can connect the tablet to a computer USB port and the 
computer has now internet access. In fact the tablet is like a 4G USB dongle 
or modem. Please note, no wi-fi is accepted at home.

 

I tried something, I connected the tablet to the USB port of the TC-W9970 
router then I went to the config software (192.168.1.1). As you may guess 
it didn`t work but I have to say I don`t understand all these technical 
parameters like DHCP, subnet mask ....... Whatever, can I connect te router 
that way ?

I also have a TP-Link TC-W9980 DSL router. Again, no luck either.

 

If these 2 routers cannot do it, what TP-Link router could connect with the 
tablet / phone to get internet access ? That router only needs ethernet ports, 
no wi-fi.
 

Thanks for help / info

Hello@DummySushi ,

Welcome to our community.

 

If you want to use 3G/4G mode, please refer to TD-W9970(EU)_V1_UG(from page 18).

It is recommended that you can hard reset the modem before you configure the modem.

Hi. I should have been more specific in my first message. I already have the user guide 
and I tried to configure the TD-W9970 router. 

 

Here are the steps that I followed:

 

01 - Login to 192.168.1.1
02 - Operation mode >>>>> 3G/4G Mode

 

<<<<< Save >>>>>

 

03 - Quick Setup Region >>>>> Canada
04 - Quick Setup Time Zone >>>>> Eastern Time

 

<<<<< Next >>>>>

 

05 - Quick Setup 3G/4G Mobile ISP >>>>> Bell (Bell Canada)
06 - Quick Setup 3G/4G Set Dial Number ... >>>>> Yes (Try this first)
07 - Quick Setup 3G/4G Authentication Type >>>>> AUTO_AUTH

08 - Quick Setup 3G/4G Dial Number >>>>> 15142093925  (This is the phone number 

                                                                                                of my Android tablet)

09 - Quick Setup 3G/4G APN >>>>> pda . bell . ca

 

<<<<< Next >>>>>


10 - Quick Setup Wireless Wireless >>>>> Disable

 

<<<<< Next >>>>>

 

11 - Quick Setup Confirm Connection type >>>>> PPP3G

12 - Quick Setup Confirm ISP >>>>> Bell
13 - Quick Setup Confirm Dial Number >>>>> 15142093925

14 - Quick Setup Confirm APN >>>>> pda . bell . ca

15 - Quick Setup Confirm Wireless >>>>> Disabled

 

<<<<< Save >>>>>
 

16 - Quick Setup Complete Tlme Zone >>>>> Success
17 - Quick Setup Complete Operation Mode >>>>> Success
18 - Quick Setup Complete 3G/4G Connection >>>>> Success
19 - Quick Setup Complete Wireless >>>>> Success

 

<<<<< Finish >>>>>


It is not "Success" as it doesn't work. Diagnostic menu says:

Here is the LOG from the Quick Setup procedure. We can see the Android tablet is clearly identified (HUAWEI CMR-AL09)
