I have 2 PC's with static IP adresses connected to tp link router TL-R402M. Router address is 192.168.1.1, and PC's have 192.168.1.51 and 192.168.1.52. This all worked well.
Now I have and ADSL connection, and would like both PCs to have internet connection. For the sake of clearance I will call ADSL modem/router just a modem, altough it has routing capabilities. Modem has 192.168.1.1 ip address also. To test the connection, I have done the following:
I connected only one PC to modem, turned DHCP off on modem and set LAN range to accept my PC static IP - and internet works ok.
Now, since modem and router have same IP, I have changed router IP to 192.168.1.2 and now two PC's can connect to router again, but cant ping modem. What do I need to set on these two devices (modem and router), so they can work together. What settings should be made for best results? I suspect one should be set in pure bridge mode, but dont know how, and dont know if it is the right/best way. Should some settings be done on router WAN settings - now it is set to receive dynamic IP address?
I have connected modem to WAN port of the rotuer, just to mention.
