I haven't tried the wired method, but here are the facts.

Wired cable Internet runs at a speed of 100 mbps.

The absolute maximum wireless internet can run at is 54 mbps.

That 54 mbps is divided among every wireless device connected to your router, so if you have two devices connected, they each get 27mbps, and so on.



So, overall, wired is preferable in pretty much every case. The only question is, is the experience 'that much' better that it justifies buying the Wii's ethernet port?

Those speeds you claim are bandwidths... throughput is a different question.

With a 100Mbit/sec cable your throughput is more likely to be about 60-80Mbit/sec

Most cables you can buy now though will be capable of 1Gigabit/sec....though the throughput is limited to things like disc-read speed now, (how that would affect the Wii with flash memory I am not sure) so you are unlikely to get more than 400Mbit/sec.

Wireless-g bandwidth is 54Mbit/sec.... but the throughput depends on how far you are from the access point, and the obstacles inbetween, and is also shared between how many devices are using it.... so if you were about 1 meter away with no walls and the only one connecting you might get ~40Mbit/sec, but the further you get from it the worse it will be. And multiple devices are sharing the data transfer rate, so more even if both of the devices are right next to the access point you would be lucky to get 20Mbit/sec.

Wireless-n bandwidth is 600Mbit/sec, throughput is more likely to be about 150-200 for a single device.

-----

Even if you had all the best stuff you may still not get an increased speed if your throughput from the ISP is poor. Using speedtest.net I supposedly have between 4 and 4.5 Mbit/sec throughput when wired in.... but about the same when using wireless from right next to the wireless access point.... in my room I am about 3 metres away physically, but also through a solid wall... I get about 3.5 Mbit/sec wirelessly.
