ok, if your not seeing your SSID (it is one of the most important part of configuring your wireless router)
then you must have turned off "Broadcast". Think of SSID like a CB radio. If you tell your friends to talk on channel 10, then only those friend will hear the actuall conversation, UNLESS, someone happens to be scanning, and hears the coversation.
Try the following steps:
1) Bring your browser.
2) Type in the following Address: 192.168.1.1
3) If you haven't change the password, then type in admin for the password. Don't put anything for the user name.
4) You should see the Linksys management console come up
5) Now look for the wireless configuration tab
6) Once you find it , find out what is the SSID field value is
7) If you have not changed it, I woudl HIGHLY recommend you change the SSID... and remember it. Also, for the time being, turn the broadcasting back on, as a check to see if your router is actually broadcasting your SSID.
8) Next to secure your router/Wireless network, select WEP for encryption.
9) This will make sure your neighbors will not steal your signal
10) Now when your doing the config portion of the WEP, the router will prompt you for Passphrase. Come up with a good passphrase, like "2LetMeIn".
11) The router will now generate 4 keys for you.
12) Use key 1, and make sure everyone of your wirelesss devices will have that key configured on them.
13) Once your finished the above Configs, then press the "Apply" button. (Very important).
Try these and let me know what you find out...
Good Luck
