For your information, AV600 is not the model number, instead, it should be TL-WPA4220KIT. 

 

Back to your case, what is the led status of the TL-WPA4220 when the wifi name disappeared?

  

Many thanks Kevin. Just FYI... I've previously purchased these items (about 3 or 4 months ago) so I'm familiar with the buttons and I was pressing the right ones. Regarding the LED status, all four LED's are solid green unless I press the wi-fi button for 5 seconds (in which case the wi-fi LED extinguishes). And if I press it for 5 seconds again, that LED comes back on again (solid green) but there's still no wi-fi output. Even if I power the unit down and turn it on again, there's still no wi-fi signal from it. The only way to get the wi-fi signal back is to press the fiddly little reset button (underneath the unit) and allow it to go through its reset process.

FWIW I emailed TP-Link's UK support (last night) so hopefully I'll get a response from them.

TP-Link Support replied a few minutes ago but in the meantime, I've made a bit more progress. Here's my reply just now to TP Support:-

" Hi there and thanks for your quick response. The model number is TL-PA4010(UK). The serial no. is 218C810B03738 and it's Version 3.0.  However... I've managed to make a little progress so here's the full story...

I first purchased a pair of these items (from PC World) about 3 months ago and I've been using them in my own house without any problems.  Then a few days ago, my sister gave me some money and asked me to purchase some for her and set them up in her house, a few miles away.  But for convenience I'm trying to get them initially set up at my house.

What's happening is that I can't set up the new ones if my old ones here happen to be already running (this creates the problem I described yesterday). If I turn my own units off temporarily I can then set up the newly purchased ones - but neither pair can be set up if the other pair happens to be switched on.  They don't seem to be sharing an SSID - my original unit comes up with the ID TP-Link_4D02 and the new one from yesterday is TP-Link_CEF2.  And yet they seem to be interfering with each other somehow.  If I try to configure either pair while the other is already switched on, external devices (such as my PC's or mobile phone) will only see 1 x SSID but never both of them. "

At the moment I'm wondering if it's because they're physically on the same mains circuit ??

@dozzler IIRC I noticed a problem where one of the newly bought ones had a particular green LED that would flash constantly (maybe about 5 or 10 times per second). Eventually the retailer sent me a replacement and that fixed it.
