After upgrading my Inspiron 1545 from 7 Pro to Win 10 Pro, I do have a wirless connection, but no ethernet connection.....I have followed all the trouble shooting that Windows suggests but still no ethernet connection. It says No IpV4 or IPV6 connection. The drivers for the network card say it is operating , and drivers are up to date. I have 11 computers and decided to try 10 on my old Inspiron. Anybody have any suggestions ???
