From what I’ve already read here, I suspect that my problem arises from my router, which is a HUAWEI EchoLife HG532 ADSL/router supplied by my ISP, TalkTalk in the UK.
When I first connected the MBL, everything looked OK. MyBookLive and MyBookLive-backup appeared as Mac servers in the “shared” section of the Finder sidebar. Bonjour could see it. WD Quick View could see it. Time Machine’s “set backup disk” panel could see it. From the Finder, I can connect as “guest” and the Public share mounts as a remote drive on the desktop (I have that Finder option set). I can see the data on the MBL (I stored a couple of photos there, as a test).
BUT, Quick View (and Safari using Bonjour) won’t always open the Dashboard, and when I try to open the drive from Quick View (and sometimes from the Finder), things start to go wrong. The same thing happens if I try to start a TM backup. I get “connection failed” messages, and MyBookLive disappears from the finder sidebar. Bonjour can’t see it any more; Quick View can’t see it any more. Meanwhile, the Public share remains mounted and accessible on the desktop.
After a while, or more quickly if I relaunch the Finder, the drive appears again in the Finder sidebar, this time as “mybooklive” (no capitals) and saying it’s a PC server. Sometimes I can open it from there, and sometimes not (connection failed).
All this time, the Public share is still mounted and accessible on the desktop.
My router says that it has assigned 4 IP addresses on the Ethernet LAN, even though there are only 2 things plugged in.
I can access the Dashboard if I use the highlighted IP address directly, but not using the server name.
QoS is disabled; UPnP is enabled. (I’ve seen these terms mentioned here while I was researching)
Firewall setting is to the ISP’s custom setting, but I don’t know what that is.
I have no idea how to set a static IP address for the port with the MBL, or I would have tried that.
Any help will be gratefully received.
Thanks.
