Desktop Pc: Win 7 Pro x64 Laptop:Win 7 pro x64, dual boot xUbuntu 11.10 Usb outdoor antenna : Ralink Ubdo-nt8 Case 1:. -Desk pc prior the Ralink antenna was using a netgear usb stick to connect on open wireless network.Uninstalled drivers. Installed Ubdo drivers and used the antenna without any problem for 3 days. Then i tried to connect the laptop(under win 7 ) to the desk via cable and share the desktops connection. Boom! After that i keep getting desconnected.Diagnose connections solve the problem for 2-3 seconds./infinite repeat ;P Windows error reports mention : -default gateway problems -wrong ip settings -and last that "computer appears to be correctly configured but the device or resource is not responding. It is not a device problem.(see case 2) Already tried what i could find online wich includes the use of: -netsh commands -ipconfig /release-renew -avira's independent executable witch checks for a virus affecting dns -Unchecked the ipv6 box under connection properties. -Also its not a problem of the wifi i m trying to connect. Case 2: -The antenna is plugged on laptop under xUbuntu with generic drivers and works great. -An attempt to share the connection from xUbuntu to Desk pc via cable didnt work.Same error reports on windows. Ubdo's support team told meh to integrate to r36(a usb router witch will handle my connections,ip settings etc) something i am not willing to do as it should work like it did. Thank you for your time reading and/or helping. EDIT: After repair installing windows 7 on desk i am able to get online without problems. I also did not try to share internet connection between the 2 pcs in fear that the same problem will arise again. I am still curius on the reasons that happened and the solution.I think it shouldnt go on that point to get fixed.. I didnt repair install the laptop so the question remains.Please dont mark the case solved yet.
