Try connecting the PC and DNS to the main host router.
If you think this maybe beyond your scope of knowledge, I would recommend talking to someone whom can come over and help you with this before attempting to update FW. The process needs to be done correctly so there isn't any problems and the possibility of bricking the DNS.
I've not got anyone who can do it for me

.....I'm a newbie when i comes to computers and networks.
like is said i'm getting on the locla area connection is "Unidentified network" on my laptop. So i'm guessing i've bought this d-link 320 thats not going allow me to use a 4tb using 1.02 fw

.......i thought i could just update the fw wirelessly via my router....would it make any difference if i bought a cross over cable? (saw them mentioned in pc to pc LAN connection guides)
