I have a Fiber optics ADSL connection which is connected to a Huawei HG8245 modem. Its IP is 192.168.100.1. I have given my friend a connection from that modem though a cat 5 cable and he wants to create a WIFI Zone in his home.
So, I gave my old SAGEM 2804 ADSL modem to connect the cable in to it directly thinking to use it as an wireless switch. But it shut off my wireless now. If he connects my wifi is getting shut down. The sagem 2804 router and modem are in the same IP range (192.168.100.10).
