I bought a brand new Dell Studio 1558 just last week. It has windows 7 home premium 64-bit installed on it. My friend who is occupying the adjacent room has a laptop with windows XP. Both of us are connecting to the same wireless router of the hotel. My friend is able to connect to the wireless network without any trouble, but when I try to connect, I get the error "DNS service isn't responding". I get this error when I run the troubleshooting option. I met two more people in the same hotel with win XP laptop and they too dont have any problem. I have gone to possibly all the forums and website but I haven't been able to fix this error :(. I have done all the basic troubleshooting but I have no luck yet. Pls help. Following is one forum where the problem seem to have been trouble shooted but not for all.
Problem Fixed (Added later)
I have fixed this issue myself. I do not know exactly which solution worked because I did a lot of changes to the driver settings. But in summary below is the list of what I did which I think fixed this issue.
1) Put 18.104.22.168 for "Preferred DNS server" and 22.214.171.124 for @alternate DNS server"
2) Disabled 'microsoft virtual wifi miniport adapter'. This was a bit tricky part because by default this adapter is hidden. It has to be made visible from the menu in the device manager.
3) Disabled all other miniport adaptors.
4) Restarted the laptop and bingo!!!
