HOW TO CONNECT AND SHARE INTERNET THROUGH A WIRELESS MODEM WITH NORMAL MODEM?

[febinkm]

I have a I-BALL Baton 300M MIMO triple wifi modem which can connect ADSL DSL and 2G/3G dongles, Now it found that my ADSL is not working. I got one TP Link ADSL2+ Modem Router
TD-8816 which has no wifi and the internet is connected to it successfully. Now i need to use that internet as wifi, for that i connected it to the wifi modem. But i cant access the internet through wifi/wifi modem, The internet works only when making wired connection with the adsl modem to the computer. when both the modems are connected i cant able to access the modem configuration add 192.168.1.1. From that i understand that i may be due to the ip address conflict, so i changed the ip of wifi modem to 192.168.1.2 then also the internet is not accesible through wifi, please help me
