Bob,
The minute I read the model you said for the linksys router I had to go look at mine.
I have that router and asked for a new one for Christmas because this router keeps dropping the connection..... in all honesty I don't even think the system is locked any more because we had to keep rebooting it.
It hasn't really dropped recently, but I'm not a tech person at all.... so I have 3 questions, but I won't be offended if it's too much to go over on the thread:
-how can I tell if it's locked/secure?
You can go to the IP address of the router in your browser and look under the wireless section. http://192.168.1.1 if you haven't changed anything. admin and admin are the logins by default. You should definitely change the PW of the router in preparation of securing the router's wireless side.
-if it's not locked now, can I password protect it without having the disk?
Absolutely. See above. the whole interface to most consumer routers is webbified and can be administered in a browser (like internet explorer). You want to turn on WAP or WAP2 personal and make up a password and plug it in. There's even a "Help" button over to the right if memory serves me correctly.
-can i just unplug it, take it WDW, plug it in and use it?
Assuming you didn't have to do anything special to set up the ISP/Internet side of the router at home, you can just plug an ethernet cable between the wall and the internet side of the router and go to work. Wireless AP retains your settings from home so all of your security and network name (SSID/Wireless network name-You should change this from the default too. Mine is WilsonFlyer-DVC, for example.) remain as they were. You shouldn't even have to connect your laptop(s) again if you saved the password when you connected it at home the first time.
-will it be secure if I do that?
If you set it up as WAP or WAP2 personal AND change the admin's password, absolutely. FYI, WEP is no longer considered secure and can be hacked in under 2 minutes by someone with the right tools. Make sure your password is something semi-obscure. Mix case (Yes, passwords ARE case-sensitive.) and make it fairly long. I actually use a SENTENCE!
Thanks, i've been looking for help with this, but don't hesitate to let me know if it's too much to get into,
