DI-624 wireless and gigabit router
The DI-624 seems to perform just fine with the ReadyNas Ultra 2. At first, I had a lot of problems. There were network hiccups in connecting to the nas, especially noticeable when trying to play...
-Dlink's web page describes the switch as green (and claims up to 40% power savings). I was going by that.
-By "marginal" I meant degraded (broken but not totally failing). For example, a loose RJ45 connection, too much cable capacitance, some other electrical type issue.
-The cable grade should be printed on the cable, if it doesn't expressly say cat 5e or cat 6, then you should try a different cable that does.
-Are you saying that ping -f -l 1470 <ip address> times out? Or that you get the "packet needs to be fragmented" message? If you set the MTU to 1472, then the maximum value in the ping command would be 1444. There is 28 bytes of overhead in the ping command which is not accounted for in the -l <xxxx>. The normal ethernet MTU is 1500 btw, so that should work well with any LAN ethernet device.
Your ultra maintains stats on the ethernet connection (network->interfaces, there is a "show errors" button next to the status). It might be helpful to look there (maybe post the errors it reports).
It would also be a good idea to check the SMART stats (under status->health, click on the icon for each drive and you should get a pop-up).
Have you switching to the other ethernet port on the ultra?
I'd leave jumbo frames off for now, as that won't solve connection dropouts, and could well create other issues.
