Hi I have a dell inspiron 15r se 5720 that is getting quite old now. Running win 10 and lately i've been encountering some dns server dropouts. Wifi working, I can connect to any server, but I get no signal. With my phone or a different laptop i get signal from my wifi, So the router is working fine but my laptop somehow doesn't get the signal. I even dont get signal when connecting via lan cable - troubleshooting tells me 'the DNS Server isn't responding'. With a mobile Hot spot my computer receives a WiFi signal without a problem though. What could be the reason for this??
