Hello everyone! As mentioned in the title, this is quite unusual. I’m trying to keep it brief—here’s what I’ve tried:
Returned home, using two monitors. Unplugged the second one to use an old monitor instead (no big deal). Started the PC, but it didn’t auto-log into my Wi-Fi. Tried connecting from my phone, but got “unable to connect.” When I shared from my phone and connected, it worked fine—except I forgot my home SSID and had to retry.
I didn’t reboot the modem or PC, used my laptop, and accessed the modem’s config page. I changed many Wi-Fi settings on the home modem’s network name. Still couldn’t uninstall the NIC driver on my PC. Rebooted again, nothing worked. Tried turning off the PC and physically reinserting the modem, then restarting it.
Finally, I plugged in the old monitor, removed its DP-VGA adapter, and suddenly the Wi-Fi connected instantly!
This only happened with SSIDs from my home modem—other devices always connected after changes.
Any suggestions or explanations would be super helpful!
Significant EMF exists in the designated Wi-Fi frequency you're using. The power for the DP port is being split between the Wi-Fi card and the adapter, which could disrupt the voltage supply (though this might lead to the card shutting down).
It makes sense now. The adapter needs to be physically close to the antenna, using electromagnetic interference to disrupt the home Wi-Fi signal on 2.4GHz. I didn’t think an adapter would generate those waves or EM fields by itself—this is what I was missing!
