I'm having the same issue. Prior to this week I was getting 4-7 MB/s speeds and as of yesterday I'm getting <100KB as the SS started archiving a new drive in the que. Standard drag and drop file transfers aren't usually a problem. The problem I' having is primarily with archiving other network drives. I'm no IT guru but I've tried everything I know short of updating the firmware to 2.3.01 (from 2.2.91) as all posts indicate that 2.3.01 is a hot mess.
Every media service has been turned off, I've rebooted everything on the network, replaced cables and I'm still getting "too many failed transfers" every few minutes in the WD anywhere backup window. Before I discount this as a really bad joke from WD (or on me, should have done my homework, this is what I get for supporting american products), I'm hoping to get some help from this forum. would anyone recommend upgrading to the latest firmware? I'm primarily using this appliance as backup and central storage for a small graphics business network.
Any help/guidance is much appreciated. In the meantime here are some funny pics for your amusement.
