Vista Wireless Performance Questionnaire

For what it's worth, all my problems disappeared after changing the router on my network.

I replaced the combo of Linksys WRT54GS + NetGear GigE switch with a D-Link DIR655, enabled jumbo frames (MTU jumped automatically) and now I get:

Vista wireless, read & write: 4.1MB/s (32 mbps)
XP wired, read & write: 17MB/s (136 mbps)

I have not yet tweaked journalling settings on the ReadyNAS, so might get some further boosts once I do that.

1) Has MTU been changed to 1492 and running Windows Vista SP1 Yes. Disabled Jumbo Frames on the NAS and set MTU to 1492. Also set MTU on the router to 1492. 2) Model of Wireless Router and Firmware used. Linksys WRT54GS, v4.71.4 3) Wireless Card Model and Firmware Intel 4965 AGN, 12.0.0.82 4) Connection Speed that you are seeing for Wireless Adapter. (54Mbps/24Mbps) 54 mbps 5) Connection Speed between ReadyNAS to Router (10/100/1000Mbps) 100 mbps 6) Throughput from Windows XP to ReadyNAS and Vista to ReadyNAS. Both Machines at or near same location. (Read/Write MB/sec) Vista - read from ReadyNAS 1.3MB/sec Vista - write to ReadyNAS 1.0MB/sec XP - read from ReadyNAS 1.0MB/sec XP - write to ReadyNAS 1.0MB/sec The XP performance seems a lot slower than I remember. 7) Throughput from Windows XP to Vista (Read/Write MB/sec) n/a don't have any XP shares visible to Vista 8) If MTU settings were changed to 1492 and SP1 is installed, Would like a Wireshark capture when transfering data from Vista to ReadyNAS Notes: I have done all of the following: 1. disabled Vista's multimedia throttling via registry tweak. 2. disabled Vista auto-tuning (via netsh command) 3. disabled Vista firewall when on local network
