Using a wifi connection just makes it much more convenient.
except it apparently doesn't
Well...it's certainly more convenient than finding a crossover cable.
Or cables and a network hub (or switch) to plug things into.
Of course if you went through the trouble of getting a switch you could have just gotten yourself a router (which is actually a router with
a built-in 4-port switch in most consumer-level units)...and since you've put that much money in, why not just get a wifi router (which is actually a wireless access point
+ a router
+ a network switch
all in one convenient appliance) for not many dollars more and...be done with it?
That way, all you need to do is set your NIC to use DHCP and know the passkey for your wireless router. Bingo! You're in. And not just when you're at home. It works virtually everywhere else too. Because that's the way it's done. And it "just works." Most times at least. (The huge number of totally clueless people who routinely access networks and the Internet without firing up a single brain synapse are proof enough.)
Contrast that with setting static IP addresses...making sure there's no duplicate addresses in use...hoping Windows sorts out which member PC is going to be elected as the master browser for the P2P...and on and on. Then, you get to undo
all of that and reconfigure your NIC back to DHCP when you want to use just about any other network out there
So no...I really do think it's both easier and more convenient to use a router than an ad hoc network. Once a router is properly configured (not a difficult task even for a techno-weenie) you need to know nada
to use it going forward. With an ad hoc, you actually do need to know something - and redo it any time you want to "net in" to something else.
The lowly 'router' is a lovely thing indeed.
