Anything wrong with the wifi connection on 2.2?

[Guest MingoChang]

Everything is working fine except wifi connection.

I have an iPod Touch 3rd generation. Yesterday I wanted to use WebSharing to transfer some files into my Mac. I was on Windows 7 at that time, and I created a network for N1. N1 failed to connect to my wifi network. It kept on scanning, several other networks were detected except mine. I was wondering if there was something wrong with my Mac, so I tried the network with iPod Touch, it worked! Then I rebooted into Mac OS, and created a network. N1 found the network but failed to connect to it. I changed the strategy, I used internet sharing. This time N1 connected to the network, and I started WebSharing, the new problem is that the stability is terrible.

Today I went to the classroom and tried to connect to the 802.11n wifi network provided by the university but N1 failed again. iPod Touch succeed. OMG, my iPod Touch is now laughing at N1.

Anybody is now facing the same issue?
