I have a Linkstation LS-GL500 from buffalotech and its very slow on 1-2 computers but working fine on other computers. Windows 7 OS is running on these two computers and I even tried changing the internet connection from a different port (from a location where the link station is working fine) to this computer but that did not help. When I try to open a folder from the link station, it takes time and most of the time it will just freeze and we had to close and open "my computer" again to browse. I tired ipconfig /release and renew to see if that helps but nothing. Please let me know if you have any suggestion.
