Wireless Networks... How Big a Security Risk?

Quote from gnome:

Quote from dandxg:

Gnome, my last telecom job, the techs assured me when you use encryption on a wireless connection you slow down the data a little bit. What's a little bit, I don't know. This was over 2 years ago. That enough tells me not to day trade on wireless, no thanks no how. [/QUOTE

I doubt that I'd notice... I trade on dialup now. :D

That's right, too funny, I forgot you told me that. Cmon man, Qwest will give dsl for 24 bucks, come in to the new milleninum! :p

"...The last I heard WPA2 with pre-shared keys is extremely hackable (just as easy as WEP these days).

I haven't run across such a claim. Why would PSK be SO vulnerable other than a number of users having the same pass key?

Can't get DSL where I live. Phone lines are too old. Comcast cable is my only choice (wife says she NEEDS broadband... for downloading copious emails from her mother, you know.)
 
XP is by default configured wrongly:

From www.grc.com on wireless network security: travellers on planes getting infected because they turn their laptop on and do not have the wireless network properly configured.

Go to "connect to" on start menu, select "wireless network connection", then "change advanced settings" => "wireless networks" tab => "advanced" and change the default "Any Available network (access point preferred)" to "Access point (infrastructure) networks only". Then afterwards for each of your network you have to obtain radio silence by going back to the "wireless networks" tab, selecting the network, then "properties" and unchecking the "Connect even if this network is not broadcasting" option.

Make sure you have installed last year October's XP update for wireless networks too! (M$N kept pretty silent on that one). (KB893357 & KB917021)
