    From Doug Laidlaw@2:250/1 to All on Sun Jun 27 20:14:15 2021
    My computer has two HDD and wifi. suddenly, about 48 hours ago, wifi
    has stopped working for my phone and (as a result) for my tablet, which
    does not have its own modem. The computer itself seems not to be
    affected. Running the system locally from a SIM from another ISP fixes everything. I have rebooted the modem. On it, the WLAN light is extinguished.

    Is there a carrier that rides on the main Broadband signal? I recall something like this happening back in the Flintstones (ADSL) era, but it
    took out everything. It was something like having a bare carrier with
    no data riding on it.

    Doug.

    I suggest to you that the WLAN led comes on when the modem gets
    assigned a lease from the ISP dhcp server.

    Yes, a lot of shoddy thinking on my part. The computer runs because it
    is on Ethernet. A separate SIM works because it bypasses the blockage.
    So is it a problem caused by the ISP, not assigning a lease?

    I can not say exactly why you are not getting the WLAN led.
    Possibilities:
    Connection to gateway is down
    Gateway is down
    Connection to dhcp servers is down
    dhcp servers down
    maybe dns causing dhcp server problems.

    Only way for you to know is to use ping to test each point of
    contact.

    I can suggest writing a script say ck_network, that pings each
    point to tell you exactly where the failure is.
    Of course it helps that everything is working when debugging
    the script.

    You would look at modem status pages and use "traceroute -I yahoo.com"
    to get ip address to ping.

    Think about it, each node in the internet path has a WAN and LAN side.
    I find it helpful to assign static ip to all devices on my LAN.
    Makes script code a bit easier.

    If you can not ping
    o your node LAN ip your computer nic is down,
    o your router LAN ip, router/cable is broke
    o your router WAN ip, router is broke or did not get ip
    from modem,
    o your modem LAN ip, cable to router from modem is bad or
    either device is broke.
    o your modem WAN ip, modem is bad or not assigned an ip.
    o isp gateway LAN ip, gateway or connection to isp gateway is down
    o isp dns server, connection or dns server is down
    o yahoo.com and gmail.com, access to Internet is down.

    wget -qO - http://icanhazip.com can get your modem WAN ip.

    If the WAN LED is out, then he's got local connectivity, but he is not connected to whatever is on the other side of the gateway/router.

    I would first suggest rebooting the gateway. If that doesn't help, I
    would call the ISP's customer service, asking if there's an outage.

    I have a ticket with the ISP.

    The answer was very simple, really. Our broadband connection is always dropping out. They are advising people to put the NBN router to one
    side and substitute a different one. When this happens, rebooting the
    router MAY help.
    The switches are on the back of the edge of the router, and not easily accessible. Immediately above the power switch is an on-off switch for
    the WLAN. I had accidentally turned the WLAN off! I switched it on
    there, and everything is back to normal.

    Then I can recommend creating/running a ch_network script to
    run in hourly cron to save you some trouble shooting time.
