Ok for the first one...
The major thing you need to find out is how to log in to your router. The way it works is go to a computer that's connected physically to the router and open IE or Firefox, some browser. In the address bar you're going to need to enter the IP address of your router. You should be able to find it in your original documentation that came with it. It will look something like
Type that in and you should get a username/password prompt which is set at the factory (and you should be able to locate as well) to something like User: admin Pass: Password.
This will take you into the router and it's configuration. If you've been using it already for non-wireless...there's little you must change.
You should have a wireless settings section, make sure you have these set up:
SSID: It has one (you said KB439...), so you can either just make a note of the name of yours or change it if you'd like to something different. For now, I'd make sure you don't have WEP, WPA, or equivalent security with keys on..because that will just make it harder at first. Make sure that you have "Radio" enabled if you have that, and that you enable "SSID Broadcast."
Now the laptop should be able to connect, given it is configured to access an open dynamic DNS type access point, with DHCP enabled. As far as networking both PC's, don't go do the same thing to the other PC like the wizard recommended. Just get one computer working on the router, then go mimic EVERY setting on the second computer. As long as you make sure that each computer is using the same Workgroup name...be in MSHOME or something easy like WORKGROUP. Also make sure that you've enabled sharing of whatever folders on each computer you wish to share. If you can't find one of them on the "view workgroup computers" thing, try searching for it by it's name (Case Sensitive). You can verify/change both the name and workgroup of a computer by right-clicking on My Computer for properties. Then go to the Computer Name tab....hope this helps.
ok i have two problems.
first id like to say never had to deal with making a network or setting up a wireless connection before, so im lost.
my cousin recently brought her notebook pc to my house, and i have a wireless router and all. so she goes on her laptop and does that scan for signal thing. about 5 of them showed up. 2 of them were named KB43903496 or something like that. then the others were actual names, like "ada," "linksys," and ""network". I assume that the names were made by the owners. i was wondering how i would know which of the is mine. and how can i make it have a name too?
i tried setting up a network between my two desktop pc's. i ran the network setup wizard on one pc, followed all the directions, and then it says "now run the network setup on the other computers." so i do on my other computer. then i restart both pc's like it says. On one computer, when i go into "My network places" and click "View workgroup computers," i get this error message: "Mshome is not accessible. you might not have permission to use this network resource. contact the admin. of this server to find out if you have access permissions. The list of servers for this workgroup is not currently available." On the other, it shows the computer, and my other computer. and when i click the computer icon, it freezes. what am i doing wrong?
