I have a Dell Latitute E7250 with Windows 10 Pro and an Intel Dual Band Wireless-AC 7265 wifi card.
I have constant problems connecting to wifi networks - the laptop either gets stuck on the DHCP auto-config address, or it appears to connect but has no internet connectivity (can't even ping the gateway, let alone DNS or anywhere else). At the same time, my phone will connect fine to the same access point.
I've tried various ways of resetting network settings, but the only thing that works is deleting the keys under
Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces and rebooting (advice from someone I trust but who was too busy to explain it!) This works for a while, but the problem then comes back after a while as new keys are written.
Can anyone explain:
- what these keys do
- what might be going on here
- is there a more permanent fix
netsh int ip resetachieve the same thing without having to mess with the registry?
