    Hi we have two LG G4's but only one can connect to our wifi internet at a time, the other just drops out. We have to turn one on to mobile data to get internet if they are both in range of our wifi? Any ideas. We have a dual band modem but even running the phones on different bands (2.4 & 5ghz) doesn't help.

    Welcome to Android Central! Try rebooting the router by unplugging its power for 10 seconds. If that doesn't help, see this guide for more tips: http://forums.androidcentral.com/amb...-problems.html

    Check the router settings to see how many devices it will let connect to it.
    The default should be 255 devices, but setting it to a much lower number, like 5, is better for security, right up until you try to connect device #6 .

    I had this same issue with 3 LG G3 smartphones. I had 1 D851 T-Mobile variant, and 2 VS985 Verizon Wireless variants. The issue seems to be that they have identical MAC addresses, if you go into settings and view advanced wifi settings, they'll show up as 00:90:4c:c5:12:38 which is what android falls back to when it can't read the MAC address. I tried CDMA DFS tool to change the MAC address, but it doesn't seem to work on 6.0, only on 5.0 lollipop. My bluetooth MAC is also identical across all of them it is 00:00:00:00:5a:ad You would need root to edit the driver file to change the default fallback MAC address, a MAC address changer app which requires root and is not permanent (you'd need to do it every boot), or a custom ROM which should be pre-rooted.
