OS Deployer, Unable to connect to server retry is in progress

Seems like the error unable to connect to server retry is in progress happens quite a bit when PXE booting, have to wait a period of time for it to hopefully connect. 

Is there anything I could try to help improve this. .wim loads but then the connection to the server takes a long period of time or just never connects.
