Couple of suggestions. 1) you haven't said what the length of the name of your Mac is. There's been random posts here about making sure it's below 15 characters, I think. Probably best if you double check the FAQs on that, though.



Second, it would be an enormous help to the folks at Sonos if you'd go ahead and submit a system diagnostic and post the number here. That would give them a leg up on helping to figure this issue out.



The only other thing I can think of offhand is perhaps a change in some antivirus that you may be running? Sometimes they update themselves in the background, and you're not always aware that they've changed. There's a FAQ on setting up various antivirus programs, as well, probably worth checking that out.

Hi Airgetiam



Thank you for the reply. My Mac name is 65+60100 which looks a bit odd. How do you change it?



Also, I saw on other threads that some had a problem with BT internet adding a Web Address Help feature last year. I contacted BT who were unhelpful and couldn't remobe this without me moving to a new Broadband package (I had been with them for 12 years). So I am moving to TalkTalk and will see if that helps. I checked the firewall and doesn't seem to be that.



I'll submit a diagnostic report.

Many thank

I am guessing that it's the + in the name that's the problem, but honestly this is just a tad outside my comfort zone. I did find an instructive FAQ here:

Perhaps change the name of your computer, and test again? At least it's something to do while we wait for a Sonos employee to swing by and look at that diagnostic.

Hi there,



Airgetlam is on the right track. It looks like your Sonos system is mistaking your computer's name for its network address. When trying to add the share Sonos is attempting to connect to a computer at a network address that is defined by your computer's name, which is an invalid address. If you rename your computer to something other than a string of numbers it may help.

Hi Jeff,

Thank you, re-naming the computer has solved the problem. The links for how to do this were really helpful.
