Didn't work for me...

I did notice an error msg appears in my log viewer every time mIRC disconnects:

Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address 007231374ACE. The following error occurred:
The semaphore timeout period has expired. . Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

Anyone knows what's going on here?
