Driving me mad
It wouldn't work (Recognised on TV so obviously talking with router but wouldn't communicate with iPad or phone)
Then I did something (but no idea what as I didn't actually change anything) in the router settings and it worked for a day
Now it's not communicating again
Anyone explain, in very simple laymans terms, what I might have to change in the router settings?
There is loads of threads about this across the internet, but none I can actually understand or follow
I have one of those POS routers and my Chromecast worked no bother out of the box. I have no idea what you may have done as the GUI on these routers is awful.
If you didn't change something and it worked, then didn't change anything and it stopped working, it's unlikely to be a settings issue (unless there's something interfering with it I suppose, but then you'd be having wider issues).
Have you tried turning it off and back on again?
Is there a firmware update available for it?
unless the router auto channel selected a lower channel number than those days on which it didnt work? Unlikely I know.
If you can, see if you can select a lower channel than 10 on 2.4Ghz on the router.
Autoselect channel could be the thing - I've certainly found that some channels work better than others (and have turned off autoselect). Same router as the OP too though I haven't tried a chromecast yet.
If you have a smartphone, download a wifi detector app (I use Wifi analizer on Android), see which networks are in your vicinity and choose the least used channel. You'll probably find losts of networks all using channels 1 + 2. I tend to pick the highest numbered ones as they're the least used.
Ours was intermittent to start with; sometimes it would be visible straight away, sometimes it would take a while, other times it would never appear and we'd have to find something else to do. The internet has a lot about strength of wifi, using a separate power supply instead of taking it from the telly, and the little HDMI extension lead that apparently works as a wifi aerial, but nothing made a difference.
In the end I was playing around in the router settings (a netgear somethingorother) and changed the "UPnP Advertisement Period" to two minutes from the default of 30; since then it's been flawless.
I don't really know why, or how, other than a guess that presumably the chromecast would advertise itself once but the router missed it somehow, so now it has a few more goes before you actually need it.

Bear in mind that UPnP Advertisement is broadcast network traffic, so will be generating a bit of load on your network. I think I'd want to be setting it a tad longer than every two minutes, personally.
