Hello, Eveyrone,
I have an Inspiron 15 laptop and am having problems connecting to WiFi access points.
I am good on the tech side so I figured out that the problem is related to the DHCP protocol.
I managed to capture logs from Wireshark and figured out that my WiFi card is not receiving some of the DHCP messages that the WIFi access point is sending (I captured logs with another computer and I can see the messages there but not on the Inspiron).
All drivers are up to date (did the update with the help of the Dell support) but it did not change anything.
Anyone has had this problem?
