Hey D, you wouldn't wanna post instructions on how to lock down this thing would ya?
I'm heading out. Have fun kids.
Later dude.
Ok, here's my take on securing a wireless router:
Many people I know who have turned on the higher levels of security usually wind up having to turn them off at some point because their connection stops working. For the literate networking user, it's not a big problem, they can figure it all out and get it working again. For the non-network-literate user, it's a pain when the wireless dies for what seems to be unknown problems.
The first questions I ask are environmental:
What is my risk for leaving it unsecured?
How close is your nearest neighbor? Can people park near your house? How many of my nearby neighbors already have high speed and/or wireless? If your nearest neighbor is over 200' away (300' for the 802.11N spec), your signal is not going to be usable to them anyway. If they already have wireless, why would they use yours? If there is no place nearby for someone to park and steal your signal, it's a non-issue. If you don't have any of these risks, securing the router doesn't add much more protection. Added levels of encryption and security just slow down the data link speeds. However, if you live in a townhouse or condo, have lots of nearby neighbors, then you want to secure the router.
I know pretty much where you live Baja, and you probably don't have issues with the neighbors or parkers. What I would do in your case is turn off the SSID. Get your wireless connection up and running, then log onto the router (can't give you the specifics, all routers have different menus) and turn off the SSID (the name your router advertises to the world). Anyone that tries to find local wireless hotspots will not see your wireless router, but it's there and working. If you have a friend that comes over with a laptop that wants to use your wireless connection, you'll have to give them your SSID and make a manual connection. If you choose to add a higher level of encryption, do not use WEP, use WPA or WPA-PSK level encryption. A little tougher to set up, but far more secure. Rather than me trying to tell you how to do it, Google something like "securing wireless networks" and I'm sure you'll find more than you want to know.
Personally, I have no security on my wireless router. All my neighbors have high-speed wireless networks and won't use mine. There is no place to park on my road. I'm not concerned about it. I don't even turn off the SSID. My neighbors do.
Hope that helps. Let me know if you need more info. And I'm sure that there will be other comments from people on here with different opinions. That's OK. You evaluate and make a decision for yourself.
You can log on to the router from Internet Explorer or fireFox, using the address of
