Yes
I've got an Ethernet connection in my room, but I want to create a WiFi hotspot so I can connect my iPhone and iPad etc over it rather than using my rather linited mobile data. What do I need to do this?

Many thanks
 
Yes, the university only 'officially' allows Ethernet.,,
 
To actually answer the question you could buy a access point.

However. You'd need to get one that does dhcp pass through and one that can get its ip from the networks dhcp server.

If you put something on the network that has an ip that clashes with something like a gateway or server you could be in some bother. Not that ive ever plugged in a test router to a production network that clashed with the gateway ip managing the fibre link between operational sites....
 
That's a good point - but everyone seems to be doing it anyway! Thanks for the advice. I did a bit of a google before I saw your reply, and I've set up the wifi sharing thru te Mac - so the Mac is the hotspot kind of thing. Didn't know it could do that, so rather pleased with that! :)

Alternatively, use a wireless router and have the router get its WAN side IP from the university by DHCP and configure its internal DHCP server to use one of the other subnets provided in RFC1918. No clash then as it presents a single IP to the network it is connected to.

So if the university is issuing 192.168.0.0/16 addresses use 10.0.0.0/8 addresses locally.

will any consumer units let you get the WAN ip from ethernet rather than the dsl connection?
 
I have 2 wireless routers running. One with the internet connection does the DHCP and the other has DHCP disabled. The second one has wired and wireless connections and all clients get their IP with no problem. There is no connection to the internet port on the second router - cable from other router and computers are all in the LAN ports.

So a router with DHCP disabled (ie a network switch + access point) should work using LAN ports only.

edit. Just to add I gave the second router a manual IP address way above the normal range so I can get to the config web interface without having to find its IP. Not tried it with letting it get its own IP from the other router.

Yes, if you buy an ethernet router rather than ADSL. These may be described as cable routers - the up port is an ethernet port rather than ADSL connection.
