Since I updated my NIC Intel drivers to support the latest Dell Lalitude, we have problems with autonegotiation and connectivity.
For compatibility reason, all our Dell switched ports are force to be 100 MB/Full Duplex.
With the latest PROWIN64 driver installed on the laptop without the PROSET installed:
- The driver set to 100MB/Full duplex and switch port set 100 FD = the real speed duplex is 100 MB/Half-Duplex
- The driver set to auto duplex and switch port set to auto = 100MB/Full Duplex
We can't set all the ports to autonegotiation because we have IP phone connected to the network.
I tried an older version of the driver. The negotiation is working fine, but when I shutdown the computer and turn on the computer again, the network card doesn't see any connection until I pull out the wire and put it back.
I could not find any solution for those 2 problems.
Thanks for helping.
