    Hello!!

    I have a new tp-link archer c20 router after configuration, the wireless network works but there is no internet connection. For example, on the z3 phone I have internet with wifi after leaving the house and returning the signal is there but there is a message no internet after removing the network and reconnecting (entering the password) internet signal no turning off and turning on wifi on the phone solves the problem (signal and internet available) after going out of range of the router again, the situation repeats turning off and on again wifi on the phone does not help you have to delete the network from the phone's memory each time I also have this problem on my laptop and tablet. Is there a badly configured router, if so, what are the settings because I tried different variants from google and it is always the same ??

    greetings

    Welcome.
    What operator services do you use, what is the router connected to (access device model)?

    Did you have any computer connected to this service without a router, on which the internet was working? If so, reconnect it, without a router, to have internet on it and from the Windows command prompt enter the ipconfig / all command - show its results.

    Everything goes on wifi, nothing is connected to the router (when it comes to receivers) The service I have from our local company (radio) is an antenna on the roof, adapter, PoE / LAN power supply, router

    At the time you took this screenshot, you were using a wireless network adapter on your computer. What does this card connect to?
    - with some operator device outside the window?
    - with some operator device (router) in your apartment?
    - directly with the antenna mounted on the roof?

    You write that you have an antenna (rather CPE), power supply to it - so I expected the computer to be connected to this device via twisted-pair cable.

    Unless you have one operator router and you want to buy a second one for some reason (only here, the question is whether you want to replace it or connect yours for some reason).

    The laptop is connected via wifi to the tp link archer c20 router as I wrote above, radio internet on the roof antenna cable from it goes to the LAN adapter and from it to the router from which I have internet for the whole house I do not use the cable connection all the equipment connects to router using wifi

    Is it talking about one and the same router, or are they two separate routers, because it cannot be clearly determined from your statements.

    There is only one router another does not exist

    Added after 5 [hours] 14 [minutes]:

    I noticed that when the internet is available, the IP is 192.168.3.XX and when there is no internet the IP is 192.168.2.XX. What to do to assign an IP device in the range of 192.168.3.XX ??

    Has someone already set up this router to work on this network?
    - if so, go to the management of this router through the browser and show the settings for WAN
    - if not, then insert the LAN cable from the PoE adapter directly to the computer (by the way, make sure that you are not connected to WiFi at the same time) - is this the way the internet works? If so, then do ipconfig / all and pop it up.

    You have reset the router with the button (you will lose all settings and you will have to reset TP Link!), Has this TP Link firmware up to date?

    The internet provider told me to replace the cable from the lan port to the wan port in the router and the internet works, unfortunately, I did not find out what caused the assignment of 2 different ip

    @ darq_1
    As the cable was in the LAN - TP Link was a kind of AP (but then it did not assign an IP because its DHCP server was turned off). When the cable is in the WAN, the DHCP server built into TP Link is responsible for assigning the address and now it assigns the IP.

    This is how to configure the router so that the LAN assigns a good ip
  • Network and Internet specialist
    In the TP Link options, there should be an option to assign a given IP (previously entered manually), then restart all devices and from then on, each device introduced there has the same IP assigned earlier.
    You configure the DHCP server in the option:
    DHCP-DHCP Settings
    And you enter specific IP data and add here:
    DHCP-DHCP Address Reservation.

    It is also worth uploading the latest software available on the router manufacturer's website to TP Link and then enter this data and save the settings in a backup copy in a file on your computer.

    First of all, you should know the parameters needed to configure the connection. We can guess them the next few posts, or maybe a colleague call the service office and receive such information within a five-minute phone call.

    If we want to guess - it would be appropriate to connect the CPE cable ("antennas") directly to the computer and see what happens (with the ipconfig command).
