    You need to support that.

    Hi StringJunky.

    Support?  it is a factual radio frequency.   A microwave oven cooks cells with 2.4GHz.  WiFi emits 2.4GHz at much lower power level;  but is there all the time.  Unsure if I prefer a leaky oven a few minutes a day or a weak emission at all times.

    Supporting the other part; the priority pursuit of lazyness and comforts by the modern way of living is obvious. 🤨

  2. Thank you, Sensei.  Not ignoring you at all.

    The delay to check all your suggestions obeys to a desire to test another thing first.  Ordered another USB to ethernet adapter and been waiting almost a week: the mailman just brought it minutes ago.

    Internet works now on both computers, Linux and Chromebook simultaneously with the same kind of adapter.  Am watching France24 news and posting this.

    Both 1Gb adapters are now equal brand and model USB 3.0 to Gigabit Ethernet RJ45 LAN (10/100/1000) Mbps Network Adapter  MJ94


    The trouble 'evidence' of using different brand/model adapters is beyond my understanding.  Am returning this 1Gb  bought at a local "Bestbuy" store :Front Zoom. Insignia™ - USB 3.0-to-Gigabit Ethernet Adapter - White.


    And this  mail ordered :

    USB 3.0 to RJ45 Gigabit LAN Ethernet Network Adapter 10/100/1000 Mbps Silver

    and have three older of these used years ago going to the spider web box if anyone needs them :


    Blue USB 2.0 To LAN RJ45 Ethernet 10/100Mbps Network Card Adapter F PC Net Sever

    The use of adapter is because newer laptops do not include LAN jacks on their push for all wifi.  Served myself a double Bourbon; -happy- 🥃



  3. At the beginning, about every health related person had an opinion on how to cure the pandemic.  I stopped reading all claims that crossed in front of me.

    By chance, another came in front of me yesterday that decided to read, claiming deaths are caused by lung trombosis; and that treatment ought to be blood thinners and not the way it has been done so far.

    Occurs to me that a good probing method would be to count how many have died while being on blood thinning medication.  Is there such a statistic that can be evaluated ?   I have been on such medication for a few years after a coronaries procedure and had no covid symptoms at all while living a nearly unrestricted life.


    -Please do not bury all related posts into one megathread-

  4. Yes, I can. (attached)   Please allow me to pay full attention to Ghideon now; will get back to you

    It never ends reporting, had to close the terminal.

  6. Thank you, Ghideon.

    Am using Ubuntu 18.04 at the computer on RJ45-1.   I can open its terminal and operate it well.  Not always interpret all it says, but I can use it.  The new Chromebook on RJ45-2 is the one evading me from finding its terminal. Perhaps has to be downloaded/installed yet.

    A hanging question is if two USB-to-ethernet adapters in the same network cause conflict. (One on computer 1; one on Chromebook).  As manufacturers trend is to eliminate optical drives, hard drives, replaceable memory, ethernet jacks in favor of all wifi/cloud/throwaway forcing the use of adapters...


  7. Thanks, studiot..

    My 'smart' phone is never used to play on the internet, only used as telephone + whatsup with the telephony provider service only and no home wireless to it.

    Went to the store, bought another USB-to-ethernet adapter similar to the pictured one.  Same "no internet" prompt.  Will dig deeper into the misbehavior and get the sledge hammer ready...

  8. Thanks, studiot.


    You say you have nothing wifi equipped in your house.

    Are you quite sure?  The gateway (modem) has its wireless feature disabled by the service provider by contract.

    Even if you have 'disabled' it on the Chromebook, won't it will still be live inside ?  Its wifi and bluetooth are off by selected choice in network settings menu.

    Some modern televisions have internal wifi as well as Ethernet connections. Mine gets the programming from ethernet RJ45-3 ----->tuner*----->HDMI, old to have any network.

    Same with printers, scanners, doorbells and other auxiliary devices. My printer is still in its sealed carton, no others.

    Printers with wifi and ethernet are often a pain to get working on the right network. That will be pain for a future day.

    If you have such a printer is the chromebook trying to set itself to the printer's own local network and fighting itself if you want to use the router ?  Printer is disabled at the Chromebook settings.

    Do you have a 'firestick' or other interface between tv and home network ?  No firestick, * it is another wired animal : ----> https://www.ebay.com/itm/X96-Mini-TV-Box-Android-7-1-2-S905W-Quad-Core-WiFi-HD-2GB-16GB-4K-Media-Player/233493321077?hash=item365d495575:g:B0EAAOSwU2BeRD4-


  9. Poking, resetting, changing parameters, trying other servers, cycling power of all devices in different sequences...  the Linux computer on Rj45-1 ended impaired too.  No internet for a couple of days, unable to post.  Interestingly, the internet television tuner on the RJ45-3 was always able to work fine.

     Removed the RJ-45-2  Ethernet-to-USB adapter below from the Chromebook and restored functionality on this, the Linux unit. Posting the progress.  Seems the adapter is flaky or kaput. Worked fine just for a few days.





  10. Side question... DNS is like a telephone directory, where names are shown as their equivalent numbers; example scienceforum.net is or something like that.

    And if the DNS is kaput, if I know and type instead of scienceforums.net that IP address "" I should arrive to this site, right ?

    Sorry,  am  s l o w .

    I do not know how to find the 'numerical' IP address of devices or sites.😪

    Thanks... I will now try the suggestions on last 2 posts.

    -All internet connected equipment at your home gets the problem, all gets the problem at the same time?  ----> Not always, sometimes one of three, sometimes two of three.
    -How is the router (modem) connected to internet? ----> Coaxial cable to the utility pole is as much as I can tell.

    Utility pole--------coax---------F connector gateway------four RJ45 jacks, 3 used to each of 3 devices with no splices of any kind and in unmolested new condition less than 6 metres length.

    -What happens if you power-cycle the gateway when problem occurs, does that fix the issue? ----> Not always. sometimes fixes one device, sometimes fixes one and impairs another.

    powering off also the devices seems to work better to restablish functionality; unsure if simoultaneity or which one delayed (device or gateway)



    Following Sensei suggestion will take longer for me to digest.  Will put good effort to understand it, even no Windows here.


    At the moment, this computer is working normal interacting with scienceforums; the tuner is showing live RAI (Italia) broadcast news but the Chromebook complains about DNS probe.failed.

  12. Greetings.

    The flag bearer of computer idiots again.

    Get the DNS probe error in a Chromebook.  Before was also in the Linux machine. Power cycling all several times allowed me to enter the internet to post this.

    There is nothing Windows in my home.  There is nothing wireless in my home.  Have three ethernet wired devices to the gateway (modem?):  A Linux computer; a Chromebook computer, a tuner that receives internet television from the whole planet.  Most of the time all works well, but something gets the 'period' and I cannot solve what cannot understand.  Reading related articles on the web; they assume everyone uses Windows+Chrome+Wifi and do not apply for me to attempt the fix.

    Any idiot-proof guidance to cure the misbehavior will be appreciated.

  13. Hi.

    Picture a bunch of solar panels on a roof to generate 3KW electricity.   The purpose, to heat a dwelling, nothing else.  No connection to mains, no inverter to supply appliances nor lighting.  Just heat.

    Powering a heater during the daylight hours, warming the dwelling plus heating up something that will release warmth at night time.  A water reservoir works well absorbing/releasing heat, but needs piping implemented toward radiators like in some very old houses.

    Barrels of rocks heated by electric elements can warm air passing trough them to release warm air at nights into existing HVAC ducts.  What if the rocks are replaced by iron scrap, like engine blocks in barrels ?  What convenient dry material would better retain heat per volume ?

  14. Found out today that China is building a 500 metres diameter telescope antenna in PingTang, to start operating in 2021 😀  Can someone explain the convenience of making this one spherical instead of parabolic ?

    China inaugura en 2021 el mayor radiotelescopio del mundo, de 500 metros de diámetro
