We own several different HTC and Samsung "smartphones", Laptops and more that all use our Home WIFI network.
Until two days ago all connected to the router and then on to the wide world beyond without a single issue, but now the phones connect to the router as usual but don't see anything beyond the local network.
The laptops work fine still. The phones will use the WIFI network and happily sync and communicate with the laptops no problem, but refuse to see the internet. Therefore no email, no market updates, no anything.
If you use the in-built browser and simply head to google, it times out saying page not available.
What's changed on the network...just one key thing.
I have just installed some CCTV with a DVR that allows remote viewing. To make this work I had to change one setting on my router.
Since I don't have and can't get a static IP address I needed a Dynamic DNS service. Easy. For that to work though I had to change my router settings from "Get DNS Address Automatically From ISP" to fixing the Primary & Secondary DNS servers. I used 188.8.131.52 and 184.108.40.206 respectively (still my ISP servers, although I know I can use any DNS servers).
The DVR works great and my camera's can be seen via my dnsdomain by friends and family anywhere in the world (great for when we go away etc).
The laptops, as I say, work fine.
All our Android "smartphones" stopped working at once.
Obviously, I can get them working by setting my router back, but then the remote viewing on the DVR/CCTV won't work, which I need.
Has anyone had similar issues/configuration that they managed to overcome and help an enthusiastic technology newbie with please?
