Hi, you need to make sure the DSL light is solid on before you install the modem. Please refer to the instruction below to do some troubleshooting first.

What's the model number and hardware version of your modem? Your line is an ADSL line or VDSL line?

@bscho  same problem here . Tried static ip , ppoe ... Not chance to connect . Tl-wr940N  . Modem technicolor 

@Geambicku 

Good day,

Thank you very much for your time and patience.

Sorry for the delay.

May I know where are you located and who is your internet service provider?

Have you tried to connect the computer to the modem directly to test the internet connection type, dynamic IP or PPPoE?

By the way, was it the first time to set up the TL-WR940N?

Thanks a lot.

I have the same problem as well. 

I am a post office customer but i want to use a different router and not the one provided. So far i have tried millions time on the web page and on the app to connect my broadband with the new router, i put my username which is my @pobroadband.co.uk and password but nothing seems to be working! I am going crazy! 

Hi guys . I managed to add router on my network changing IP to static . P.O gateway is 192.168.1.1 the same as my tl wr940n . 

Solution : change your router IP  from 192.168.1.1 ( used also by P.O) to 192.168.10.1

Wait 1 minut and will work .

If doesn't work just reset and try again

Now i have a different problem ,  as i installed ddwrt on it but i didn't realised as is an old teh. Cannot reverse to stock firmware . I ve got the webrevert files but no reply from ftfp

@Silvi  explain to them you need ppoe /ppp login details as you want to change the modem . Your account details used to login to see /download bills is not the same eith ppoe details . I did same and i have my username and pass .
