I would not be surprised it worked wired, do you have a Dynamic IP set or is it static ? for your system i mean. If the IP is set Static on your system you may want to check the DNS address entered, change it to dynamic and then try. If this is a continuous occurance you may want to Reset/Upgrade the firmware of your Broadband Router, again if its DSL then please save the settings before doing so, else you may be cut off Internet completely.
Hi, I've been using my Dell Vostro 1500 (Vista Business) wireless for quite some time when all of a sudden I received the following message, Error 105 (net::ERR_NAME_NOT_RESOLVED): Unable to resolve the server's DNS address. I am connected to my wireless network, and can see other networks as well.  No browser on my laptop will work. I have run all the possible, but to no avail I have a broadcom 440x 10/100 integrated controller and Intel(R) PRO/Wireless 3945 ABG Network Connection. Please help!
