I know this has been covered in blogs and forums many times before but nothing I have found seems to address my problem directly. At work I have an ancient work Windows XP laptop to use but the problem is that it's so painfully slow to use I can't bare to use it. So, I take my macbook into work and do all my work on that and use tethering from my iPhone for internet. I'd rather not using tethering, so today I pulled the wep key from the work laptop and all the network details, input them into my mac and connected to the network in order to use works internet connection. So my macbook and work computer now have the same: IP Address (Manually assigned. DHCP is disabled on both laptops) Subnet mask Router Address DNS Servers Proxy Server settings But even though it say it's connected to the network, I can't connect to the internet. Is there something else I could be missing?? *I didn't touch the WINS server settings because I assumed they are for the local office network and not to do with the internet? *I also assumed they have no mac address filtering system in place as I am able to connect? Is that right? Also, whenever I connect with my macbook I make sure my work laptop is disconnected to insure there's no ip address conflict.
