Hello.
I am creating a new topic because I have a problem with the WIFI network that I cannot deal with. I haven't had a wireless connection for two days .. It started with the fact that I did not notice that the switch of this network, which is located on the front of the laptop under the controls, had just turned off. When I realized that this was the problem and turned on the detection of wireless networks again, it found my network for me, it connects to it, but there is information about the lack of internet access, as well as a black exclamation mark on a yellow background on the taskbar next to the WIFI icon .
I read all the forums, tried all the things that were recommended but it didn't work. In the network state, there is information at IPv4 - no internet, and IPv6 - no network access .. So I tried to manually enter the values for Ipv4, it did not work - but when I set it back to determine the IP address automatically, I already thought that the problem was resolved - because the exclamation mark disappeared from the taskbar and the information that there is internet access appeared - the same when I entered the network with Ipv4 this information appeared. Unfortunately, to my dissatisfaction, there is still no internet. I tried to reset the router twice (TP LINK TL-WR741ND), checked the network card drivers (Broadcom 802.11g) - the information says that the drivers are up-to-date. I would like to add that the Internet is not available on all devices - i.e. a second laptop, mobile phones. The only way to connect to the Internet is via a cable. I am adding 5 photos, gentlemen, which may tell you, as professionals, something where the problem may be. Thank you in advance for each tip and help in solving my problem. Regards Maciek

I did as my colleague recommended above - I connected to the WAN, restarted the cable modem and all the necessary parameters jumped in in the WAN settings and the wireless internet works
