|Stuart...I know very well what the abbreviation stands for...no need to get nasty.|
I didn't see his response as nasty. It wasn't even sarcastic. Just a simple statement.
However, on another site someone who 'sounded' quite knowledgeable emphatically stated that the wired computer attached to the router need to be able to handle WPA2
Well, whoever said that is an idiot. I am a Network Technician by trade and have been holding this position for 5 years now specializing in networking in it's every form. I have almost 15 years of computer related experience prior to taking this position on and I can tell you that statement is complete garbage.
As StuartS said, a wired connection needs no WPA encryption updates.
When configuring your wireless network (WLAN) you apply WPA2 encryption to the wireless network you're enabling. This means, any wireless clients that wish to connect need to be able to use WPA2 encryption, must know the SSID (if you choose not to broadcast it) and must know the password. This does not apply to wired connections, only the wireless ones.
