Windows 10: When Desktop with ethernet connects all devices on WiFi shortly loses access to the internet

Hi,I have a home network with a sagemcom router/modem.To the router we have all devices connected via WiFi, except for one single desktop PC which is connected with an ethernet cable. The problem is, that when I turn on the desktop connected with ethernet all devices connected via WiFi shortly loses internet. Note, they still have access to router and home network, but they lose internet access. This goes for home consoles Xbox, Playstation etc., tablets both Android and Apple, phones both Android and Apple and laptops all windows etc..For most devices, the internet access is regained

Randomly losing internet connection on a wifi network

Is that ipv4 pool for DHCP? I usually set fixed IP addresses outside dynamic pool (so above .64 in your case)

Other solutions: like Superfly suggested, new wifi adapter (USB solutions in your case), and found one old HP thread... uninstalling HP hotkeys worked for someone - looks like app was messing with physical key...)

 

Internet Slowdown on my Desktop - Ethernet Connection

Thanks Vijay. I went through your steps other than the repair upgrade, and there was no change. Before I do the repair upgrade, I want to check on another angle.

I went into Networks and Sharing and realized that Windows is simply not recognizing my Verizon modem/router as the Ethernet connection. The slow internet access is due to the fact that the desktop is picking up the WiFi signal, and it's not strong on this
device.

For Ethernet, I get an "Unidentified Network" and when I click on Ethernet Status, the IPv4 and IPv6 connectivity lists "no network access". Looking at the Ethernet properties, the "Connect Using" lists Realtek PCle GBE Family Controller. Shouldn't it
be the Verizon modem name? Also noticed that the Microsoft Network Adaptor Multiplexor Protocol is unchecked. Not sure if that matters.

I think what I need to do is somehow configure the Verizon modem again, but not sure how.

The router is a Sagemcom B-Box 3 running the ISP's software. It does not have user-accessible logs but I can see what devices are currently connected. When the computer loses internet access, it still shows in the list of connected devices, as I would expect.

The available IPv4 pool is 192.168.1.2-63 and I statically assigned 192.168.1.63 for that last test.

The computer is an HP Elitebook 8460P with a Broadcom BCM43XX wifi adapter. The driver is the latest version.
