Hi, I've recently changed my wired network to a wireless solution. I bought only DLINK equipment: 1 x AP DWL-2000AP+, 4 x DWL-G520+, 2 x DWL-G650+. All 54Mb. I have a Windows 2000 Network: - All PCs wireless connected to AP - 2000 Server connected to a switch - Switch connected to Router ADSL WAP Off, WEP Off, 54Mb speed. Signal between 80 and 90%. All the equipment is in a small room, no interferences. If i use only internet access on the pcs, the wireless connection works ok. But if I try to use windows networks services (windows shares, file copying, printing, etc.) I loose connection after awhile. When I try to copy a file from a wireless PC to another, after a while, they loose connection, and the copy gives an error. The network adapter looses the connection to the AP. It seems that when I use full wireless bandwidth, the wireless network isn't capable of handling such data. Or maybe it's a problem with Windows 2000 implementation or Dlink drivers... Ping times are all <10ms when I have a connection. Even tried to use 11Mb and 22Mb but the problems remain the same. I also change the AP to a 11Mb USR Router... and the problems remain. Has anyone ever had this problems and did you solve it? Thanks in advance. Any help is appreciated. Kind regards, Pedro Alves
