Problem with wifi, after seconds lose internet

I have problems with some networks in Ubuntu 18.04 When I connect to the network, everything is fine. A few seconds later (5/10 seconds) it stops working, from the browser I get DNS_PROBE_FINISHED_NO_INTERNET

If I execute ping 8.8.8.8 I get a similar result, the first few seconds works fine and then I stop getting a response.

• This started to happen to me when I changed the router. The router I bought is a tplink AX50 and all the devices in the house have been able to connect without problem, except my laptop with Ubuntu.
• it had already happened to me when trying to connect to some other networks
• I can also connect the laptop with ubuntu to the wifi of the cell phone.

I have seen many similar questions, but most have no answers and nothing has worked for me

If I execute wireless-info from https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info

In the first 5 this https://file.io/spiCULPLKDqC is te result.

20 seconds later, when the internet not work this is the result https://file.io/UtgjgHSzgYfS

I can see some differences with meld, but I don't know anything about networks, the only one that catches my attention is the following

authenticate with <MAC 'OtraRed' [AC8]>
--
authenticate with <MAC 'OtraRed' [AC3]>

After much testing the solution to this problem was simpler. I had a docker network that collided with the defaultgateway of the new router.

br-7aaa6112e94b: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        inet 192.168.0.1  netmask 255.255.255.0  broadcast 192.168.0.255
        ether 02:42:1d:07:cb:39  txqueuelen 0  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

I have removed the docker network and problem solved
