I have a problem with local area connection on Windows 7 64bit. I have laptop dell n5110 and Realtek PCIe FE family Controller installed as driver for my Ethernet controller on it. But I am getting error and I can't go trough network identification. When I run this Windows diagnostic tool it says, that my local area network adaptor has no valid configuration of IP protocol. But in IP protocol settings I have set that IP address is obtained automatically.
I have also two different laptops connected by Ethernet cable to my router and the connection works (and of course o tried to switch cables). So, I suspect that this Realtek driver is not compatible with my router (DLink DI-524) and there is no other driver I was able to find for dell n5110 laptop.
