Copying Large File via SSH/SFTP over WiFi link Always Stalls and Freezes Host
SSH Host 'PC-A' runs Xubuntu 6.10 (2.6.17-11-generic) with gnome-core v1:2.14.2, openssh-server v1:4.3p2, and connects via WiFi with WPA-PSK (no rekeying).
It has a 1.4GB image file on it that I want to copy to 'PC-B'.
PC-B runs Ubuntu 6.06 LTS and has a cable LAN connection.
How ever I try to download this file from PC-A to PC-B the download always stalls:-
a) via Gnome > Places > Connect to Server > SSH etc - usually after about 200MB
b) via SFTP from Gnome Terminal - usually after abt 1000MB
c) via SFTP from console - usually after abt 900MB
Every time, it causes Gnome to freeze on the ssh host PC-A, both keyboard and mouse, and it is then unreachable on the network so I have to reset the PC.
BUT CABLE IS OK. If I switch PC-A to cable, I can download the whole file without problem.
PC-A uses a Buffalo WLI2-PCI-G54S adapter with ndiswrapper and the bcmwl5 driver. It seems to work fine otherwise eg: Firefox, Thunderbird, Gnome Terminal via SSH (other than this download). iwconfig shows 100% link quality.
Any ideas anyone?
