Apple Products - Wireless Issues

Specs: Windows 7

Hello - very strange issue here, please bear with me.

On our home network, with a DLINK 655 as the router and COX Cable as the ISP. We have 2 Iphones (4 & 4S), a new MacBook Air, iPad 2, a Windows 8 PC and a Windows 7 laptop, as well as various other devices (Synology NAS, Samsung TV etc)

On January 9th at 9PM, every Apple device dropped the network - 3G on the devices that supported it still worked - but while it showed the WLAN as being connected it was not loading any web pages, email, messenger services etc. I should say that every other non-apple device had internet access unhindered.

On the night of the 10th after power cycling everything multiple times, the problem still unresolved I decided to contact Apple Care through our contract with the MacBook Air. They were generally unhelpful and very confused and in the end told me to buy a new router.

I discovered that the Apple Devices were getting the wrong router IP address - displaying the gateway as 192.168.1.251 (should be 192.168.0.1) and renewing the DHCP lease gave me the correct IP in the right subnet for about 5 minutes allowing me to get online - but then reverting back to the wrong router IP. What is also interesting - is using the DLINK router admin page the wireless sessions listed the apple devices, confirmed with MAC addresses, but the IPs on that page were listed as 0.0.0.0 .

Yes - all this happened at 9PM on 1-9-13. .

Short of buying a new router, which is working perfectly for everything else. Does anyone have any insight into this matter? Interference maybe? Are the Apple products being picky?

I also deleted all the network preferences on the Macbook to insure clean network settings.

It is also relevant to point out that this setup has been working flawlessly for over a year (the Macbook Air for 2 months) using different ISP in different geographical locations.

Have you checked that there are no other wireless networks visible to your devices. It sounds as if they are getting their settings from another network.

Indeed. The SSID matches the network I have in my house.

It might be the router. I am able to get on my neighbors network fine - and DHCP on his network is working as intended.

What I do not understand is why a DLINK router suddenly decided to discriminate apple devices =D - with no configuration changes on any device.
