When we are connected to the wired network at work we can resolve DNS fine, however when I am on my Sprint card or when my co-worker is on his Verizon card and even when I use the Wireless on the laptop at home using my linsys wireless I cannot resolve DNS to the internet. I can ping www.yahoo.com and other sites and if I enter the IP Address in it works and takes me to the site but if I type in www.yahoo.com it comes back with site not found. While wireless I can get into our VPN for work (I think because it is using an IP to connect) and then once on the VPN I can connect to the net since the net is resolving to our domain server at work.
I need to know what could cause this, it was working fine on all laptops in the company and now one by one they are stopping.
Again this is an issue when going wireless outside the company, when i an wired inside or wireless connected at work it is fine, but when I am outside work DNS is not resolving but still connecting usine IP Adresses.

I have one desktop that by this week will have dsl and I wanted to have internet on my a bit old desktop so my kids can play with it when I am working on the other one.
how can i do this??? i am so confused. Do i need a router and an adapter plus ethernet cable???
I would like to just do it wireless and not deal with having cables going from room to room....Please help I am really so new to this wireless and stuff I am not sure I get it.
Do I just need a wireless (ex Linksys) that I can connect through the usp port (i dont want to open the tower). Then is that it?? Or do I have to have something else on the pc with the dsl connection???

My setup:
Netgear wireless router, two PCs, laptop

I connected this router that I had laying around and was not able to connect to it thru internet explorer. I reset it to the factor defaults and still nothing. I was getting an IP address on each PC/laptop using DHCP. I was also able to ping any of the PCs on my network and got a reply. I couldn't ping the router and couldn't connect to it thru IE on either a wired PC or my wireless laptop.

I'm pretty sure I was pinging the correct router address because I reset it to factory defaults. Also, the manual instructs the user to type in www.routerlogin.net in IE to connect to the router to make changes. Still nothing.
