Extremely poor network I/O performance in Vista

[imported_jediknight]

Connected to a 54Mbps wireless G connection. Copying some files from another machine on the network.

Speed I'm getting? ~840KBps.

Something is seriously wrong here..

Any suggestions?

how about giving us the driver version and the device? Driver name would be helpful too

 

[imported_jediknight]

It's a Dell Wireless 1505 Draft 802.11n, with a driver provided by Broadcom, v. 4.102.15.61.
This is on a brand new Inspiron 1520..

Do a search in the Networking forum. Disabling autotuning fixed it for me, but if you actually look in the proper forum, there are several things you can try.

There's a hotfix for this although it may or may not fix your situation: http://support.microsoft.com/default.aspx/kb/931770

You can download the hotfix here (check the digital signature once downloaded): http://thehotfixshare.net/down...guage%20Neutral/Vista/

or here from Microsoft: https://support.microsoft.com/...d=sw;en;1410&WS=hotfix

Note that hotfixes are not fully tested to work with other updates and hotfixes.

This topic looks more like a Networking topic, so it is being moved to Networking from Windows/PC Software (which is for apps & software topics, not OS topics).

840KBps is about 8Mb/sec. (b=bit B=Byte 1Byte=8bits).

8Mb/sec. is not beyond pathetic for Wireless.

802.11g at it best provides about 20Mb/sec.

You did not indicate any thing about the hardware and the environmental condition. A noisy signal environment and an obstructed positioning can easily yield such a Bandwidth (and lower).

20Mb/s is even a stretch (imho) unless you happen to live in a faraday cage.

OP. wireless is slow, you live and deal with it. When I need to do large copies, I either plug in, or just start it when I'll have a few minutes to wait.
