    I hope that this is the correct location to post this issue, and that this request for assistance finds you in good health.

    The core issue in my home is that I cannot connect to the WiFi router, an all-in-one modem+router provided by my ISP. The brand is Arris, if that helps ascertain what I'm talking about. Now, I run an Ethernet cord from the router to my computer: the computer works just fine. As of a day ago, though, none of the home's Apple devices will connect to the network, despite reboots, password retypes, and shouting at them. Each device (two phones and an ipad) can identify my network, but they cannot join. Additionally, there is an old laptop that cannot connect anymore.

    Here's the wrinkle as near as I can see it. The Nexus 7 connects just fine via the WiFi, and it has not needed to reboot or to have the password retyped.

    The aforementioned devices have suddenly stopped working, and despite searching these and other forums, my Google-fu has not yielded any answer to this particular question AFAIK. I have seen others post this information, so though I'm not sure it's relevant, I'll provide it just in case. Thank you for your time and attention in this matter, whatever you feel that you can and have spared.

    i would do a powercycle on the equipment

    do you have the exact model of the arris modem/router - may need a factory reset

    ------------------------------------------------------------------------

    How to power cycle

    “power cycle” process to reboot or reset the modem/router
    • Switch off all the devices modem, router and computers also unplug their power cables.
    • Wait at least 1 to 5 minutes,
    • Plug the power cords back in, but don’t switch them on.
    • First turn on the modem and then wait for a few minutes for it to settle and all the lights to become stable.
    • Next switch on the router (if a separate device) and then wait for a few minutes for it to settle and all the lights to become stable.
    • Now turn on your computer, You should now be able to access the Internet.

    I have power-cycled all devices, including the router itself; unfortunately this has had no effect :(. The Model is TG862G/CT.

    Thank you again for your assistance.

    The router does not let me log into it using the default 192.168.0.1 address, even after a factory reset. I am attempting to set up a new wireless network as we speak, though I confess I'm not tech savvy and will probably be delayed. Is there anything else?

    By the way, thank you for finding that manual.

    Using Windows 7, I went to control panel >> Network >> Set up a New Connection >> found the router's post-reset name, typed in the new password. I haven't been able to change its name or password as of yet, but I'm thankful to see that it's still there. Actually, after the factory reset you recommended, Etaf, the iphones and ipad are now able to connect! I'll have to re-type the extra huge key into all the other devices now, but my family will thank you for it.

    Are there any other precautions that I ought to heed, in case I've only stumbled into a band-aid fix?

    should be OK - if you have a good password - that is not just a dictionary word
