    Since switching from rural fixed wireless to satellite, the two android phones in the house won’t stay connected to the wifi. Sometimes the connection lasts 5 seconds, sometimes 15.

    Dlink DIR 826L router, an LG G5 with Android 7, and a LG G4. When the ISP switch was made, the router’s IP address was changed from 192.168.0.1 to 192.168.10.1. iPhone and PCs work. Tried static ip on the G5.

    If you haven't already deleted (forget) the WiFi entries on your Android phones and adding your home WiFi network back again than try that.

    If you have anything like Avast or McAfee or whatever on those phones, try going into their Settings menu, disable all their features, and reboot. Those anti-virus/anti-malware apps are only marginally successful at actually finding problems and often create just as many network connectivity issues as what they claim to prevent.

    Try setting up guest network on your Dlink router, using just the basic default settings and see if your Android phones can connect properly to that guest network. If they do, than peruse through the Settings options in the guest network with your main network and see if there's anything setting transferable to your main network. If nothing is apparent you might also want to just set up a completely new WiFi network (different SSID and password). It's a bit of a hassle as you also then need to re-connect your other mobile devices but if that's what will work to get everything connected it's better in the long term.

    Thanks. I have restarted the phones and completely reset the router already. Tried the guest network idea without any security or anything and the problem still exists.

    Can you connect either of those phones to other WiFi networks (a friend, or work, or public network)? At least that might indicate if there's an issue with your home network or the phones themselves.

    Yes, I’ve tried that. Work normally on other networks.

    Turning in a real head-scratcher, although that does point the problem to be more likely be your home LAN. Your D-link if not a little dated is still a more than capable model. If you haven't upgraded the firmware there's a 2013 update:
    http://support.dlink.ca/ProductInfo.aspx?m=DIR-826L
    Doubt that has anything to do with this issue though, but it's good to always keep your router up to date regardless.

    Maybe try disabling IPv6. Even now as it's become more prevalent it can cause connectivity problems with Android.

    That IP change shouldn't be an issue if you've forgotten/re-added the WiFi entry. Try booting one of those phones up into its Recovery Mode and wiping the system cache partition. I don't think WiFi setting info is even in the system cache but maybe there's just some corrupted WiFi-related data at a system level in the cache that needs to be cleared. And it won't really hurt to do this anyway, clearing the system cache is a non-destructive process that has nothing to do with your stored data.

    Another thing to try is boot up a phone into its Safe Mode. While running in Safe Mode if it can connect properly to your WiFi network that would indicate some app you've installed that's creating a problem. Of course then you need to figure out just which one is the culprit.

    It was the IPv6. Thanks so much!

LG G5

The LG G5 was launched April 1st, 2016. This was some of LG’s biggest innovation yet with the introduction of dual rear cameras, always-on display, and an interesting modular design concept. The modular design never caught on.
