Vista Wireless Performance Questionnaire

I have been experiencing this same problem: good speed on wired connections with Vista but almost unusable on wireless connections with Vista. I have now changed the MTU on my ReadyNAS NV+ to 1492. This has the following result: Wireless access is now fine but wired access speed is halved. A 138MB file took 6sec to transfer at MTU 1500 and 12sec at MTU 1492. My feeling is that this is a compromise rather than a solution but at least I can now access files on the NAS with my wireless laptop. Would wired speed be improved if I were to change the MTU on my wired workstation to 1492 to match the NAS?

I have also encountered this. Setting MTU to 1492 on the NAS and on the router led to Vista wireless access being usable, but Windows XP wired access was significantly slowed. Oddly, only *reading* from the NAS is affected - this has come down to 11MB/s - *writing* to the NAS still takes place at 21MB/s. (Wireless connections read and write at about 1.3MB/s.)
