it depends on your actual router brand it should have given the instructions in their manual on how to do that but I can help . In general all routers come with a default user name and password, say you have a linksys router you would type in a specific number in the address bar of your browser which would take you directly to the settings area of your router for linksys it is the following URL: http://192.168.1.1/ you would first see the page asking for user name and password the default for it is generally admin for the password and you can leave the user name blank or use admin for it also, that is what I am talking about when I say to be sure you change that because as you can see every single person that owns a linksys will have that same user name and password so getting access to one that has not been changed would be very easy we all know the info, that info is readily available on google. This link shows you what I am referring to. Linksys WRT54G Wireless-G Broadband Router About the WPA2 settings for wifi at this point in time it is the most secure method available on most routers, In the set up you are able to select which type of security you want to use that would be the one to select. In that link I posted above since it is older they mention WEP that was the old one that WPA2 replaced so you would not want to use WEP is is not nearly as secure.(most routers will have a drop down list of several choices you will want the WPA2 personal) They also mention MAC address filtering that is one more way to add security but it is easily spoofed these days so I don't usually bother with doing that. (MAC address has nothing to do with a mac computer by the way, all computers have a MAC address) I personally also like to change the default SSID which is the name you will see when you look at the list of wifi networks it is what your network is called, do not use a real name for this you want to use something that would not direct someone to your home simply by seeing the name of the SSID, so if your name is Jones do not name the SSID Jones or anything like that, for example in my list of my neighbors I see one called Pandoras Box, one called BlueBird, and one with my neighbor Harry's actual name, I know that wifi is my neighbor Harry but the others no idea who they belong to. You can also set it not to broadcast so no one would even be able to see it but that is very easy to defeat with some free programs so best just to use a good name and not bother with that. Most of the routers today will come with software that leads you through all these steps easily one at a time, the important thing to remember is WRITE DOWN these usernames and passwords they are very important especially the really long one that will be your wifi network password, I recommend taping them to the router itself, under it but do not block the vents. You need that wifi password for anyone that comes to visit you and wants to use your wifi network or any device you may want to add to your wifi network. You have the option of allowing it to generate your passphrase for wifi I always do that, it is not something I can possibly remember so I make sure I have it written down in locations I can find it when I need it. The admin password I mentioned is the password to your admin account on your actual pc. I set up limited user guest accounts for people that come over to my house to visit and may need to use the pc, no one ever uses my admin account but me. That would be in your windows settings under accounts where you can create new accounts and set and change passwords.

You will find the answer to all your questions at this link. Here is a link that might be useful: Facebook help

I take it from your post that you are logged in. Maybe you need to download a program --like Adobe flash player or update your programs to be able to do some things??? I'm not sure. I think facebook has a lot of problems. Originally my name would only come up every now and then when I or someone searched for it -- It was very strange. I contacted them and they did fix it (thankfully), but it just doesn't seem like something that should he be happening -- I mean my name should either come up or not -- why only sometimes come up? -- what program does "sometimes"???... That's a Huge glitch. My girlfriend mentioned that she can't receive stuff (food, smiles, etc) when she does it freezes her phone (she's using her phone) so maybe it has something to do with the system you are using??? Hope you figure it out; let us know if you do. I would bet your log in setting is just set wrong (like my name was). Have you tried changing your password and re-logging in just to see if that would help? Good luck.

I would guess it depends on her settings. If you want to say something no one else can read, send her a private message... :)
