The FAQ on the ReadyNAS.com forums states:

Starting with RAIDiator 3.01, there is comprehensive memory test that you can run on the ReadyNAS. To invoke it, power-down the ReadyNAS and depress the front power button, until you see all disk LEDs blink together for the 5th time (ignore the quick flash at the beginning). Disks will blink for about a second at about the 5-, 10-, 15-, 20-, and 25-sec mark. Release at that point. The first disk LED will come on to signify the first of an 8-stage memory test. The LED sequence for the 8 stages will be in binary format going from left to right. When all disk LEDs are lit, the memory is good. If the first and second LED blink, followed by the 3rd and 4th LEDs, in alternating pattern, the memory is bad.

Please keep in mind that the success rate for flagging an actual bad memory is about 85%, so we do recommend that you run this test twice.

Thanks!

Performance was PAINFULLY bad, and no matter what I tried, it didn’t work.

I used your MTU setting of 1430, and the performance is much improved.

I have a ReadyNAS Duo drive which for my wired connections has been working fine, but the wireless ones were so bad.

Once again, thanks a lot, you are a life saver!

1. It can lead to problems. Not sure why (I don’t work for Netgear), but it does seem to create issues for folks when they create objects (users, groups, shares, hostnames, etc.) with the same name.
2. Linux-based devices (and OSX, for that matter) have always honoured case-sensitivity when naming files and I doubt that the Linux-community-at-large would allow any change to remove case-sensitivity.

This work-around is strictly for wireless issues in Vista/Win7 and does not require modifying the MTU on the NAS (you can leave it at 1500 or with JF on).

If having issues with wired gigE, then you may want to change the MTU on the NAS to 1492 to see if it helps. Obviously, if other machines are working well with JF on, then they would suffer a performance hit on writing to the NAS, although it may be your only recourse to make Vista perform adequately.

I do not want to degrade performance for my entire network just because Vista doesn’t play well with others.

Any insight would be appreciated.

2. Since this is basically a linux machine. I have noticed there can be issues with capitalization sometimes. Where Linux cares and Windows doesn’t. Accessing directories that were created with uppercase can sometimes cause issues. Wish they would fix that.
