try a full power down of everything I do mean everything. Power off the computers, the router, the modem etc. leave all power off for 5 mins or so, then power up in this order, power to modem only let it get fully lit up, then power on to router, let it get fully lit up, then power up your computers letting each get fully loaded. Then try to connect to your wireless, I assume you have put in your wireless network passphrase for the laptops that are trying to access the wifi network.

Just to add,your wired computer must be turned on in order for the wireless to print, at least mine does I found out.

fwiw WPA is the security most would use. One passphrase of 20 charatures is recommended by most to make it virtually unhackable. That security is to keep others out of your router or off your internet connection. Many people screw up writing down passphrases on paper and/or retyping it in. Can't connect complaints usually blaming it on other things are frequently solved by whoops, my passphrase was entered wrong. Copy & Paste passphase is virtually foolproof. But requires a bit of though. Dont push the OK button until you've pasted it onto notepad or something. WEP is ok, but there are programs Johnny Jr next door might use to gain access in a few minutes. One of those four WEP keys is designated the primary key with a bullet or check box... that checked key you would copy/paste into your computer for the passphrase or key. You're not going to be automatically given a key in your home. Maybe at work when login & security is handled off a server. When you do credit cards and other secrets online usually its on a secure web page and those web pages are encryped so mr bad guy & neighbor are not able to see anything except googlygoop.

The desktop probably has a wired network card that is currently connected to the DSL Modem (GT701). Disconnect that. The GT701 hooks up to the phone line. The TEW-633GR connects to the GT701 by a network cable. Connect the WAN port on the TEW-633GR to the connection on the GT701 where the desktop used to connect. Connect the desktop to one of the LAN ports on the TEW-633GR. There should be some sort of setup for the TEW-633GR. I don't know the exact steps you'll need to take, but there's probably a setup routine in the manual you can follow. I would suggest that you do the following: Change the SSID on the TEW-633GR Change the admin password on the TEW-633GR (and make a note of it) Set up the TEW-633GR to use encryption, preferably WPA set up the wireless on the laptop to use the same WPA settings as the TEW-633GR I've done this a lot, so some of these things seem simple to me and I've probably skipped steps. If you need more details, post back here and let us know.
