thank you for welcoming me in the community as well as the troubleshooting that you have performed.
IPv4. I can see that the change to IPv4 took place, thank you.
Additional network with “2.4GHz” at the end. After restarting and later on resetting the modem reset as was advised - I still cannot see the additional Wi-fi network with the name with “ 2.4GHz at the end” (please see the screenshot below). I also have restarted both computers. Can you please have a look at this one more time?
Connection via LAN cable. I have done again a test with the LAN cable. Internet speed is not improving at all. So..this question of mine remained without an answer. LAN cable supposed to improve the speed. When connected with the LAN cable (original one that came with the box) the laptop is placed next to the box and no change in the speed takes place. I have done this test with two different laptops. Can it be that the max speed that i can get from UPC in my place is 400 Mbit/sec irrespective if it is LAN or WiFi (?)
Look forward to hearing from you.
