Not sure what the problem is, but I am used to being able to access other clients on my LAN via their hostname. We got a new router from plusnet (Netgear WNR1000v3) and now this has stopped working.

For instance, if I were to run a web server from one computer with the hostname TomPC usually I could go into a browser and type http://TomPC and I would get the web server front page.

I can access it by using the LAN ip of the machine. e.g. http://192.168.1.1 works fine.

I thought it would be a simple option in the admin panel of the router - possibly I had to turn on DNS/DCHP or something. But I can't see anything, and my searches on the internet seem to turn up ridiculous solutions involving setting up a dedicated DNS server on my LAN. This is just a small home network - really I just want to be able to access my Raspberry PI on the network without having to work out the IP address every time. (I know I could just set a static IP address for it, but using its hostname would be much easier).

DCHP is enabled in the LAN settings part, although RIP is disabled (I don't know what the latter is) I don't know if this has anything to do with it?

Many thanks!
