I found something interesting with my new iPAD.
I am having some issues, I called Apple and they are sending me a new one. I have an iPad 3, 32GB wifi only model. I would basically lose connectivity if I got further than 30 feet away from my wireless access point (D-Link).
I tried some different troubleshooting techniques last night and one appeared to work. I have two routers in my house, one is a D-Link, the other is a crappy AT&T 2-Wire. I had them both on the same SSID for 4 years no issues. They were set up so my entire house is covered. The D-Link is set up as an access point with the 2-wire router acting as the DSL modem and the DHCP server/router. I've used it for years like this, no problems. The D-Link is a "N" router, the 2-wire a "G" router. WPA encryption was used on both.
I have 3 laptops (windows, Linux), 3 android phones with wifi, a Wii, a Playstation 3, and an Android tablet all sharing the wireless network. I decided after I spoke with Apple to change the SSID of my 2-Wire router. I left the D-Link with the orginal SSID. The iPAD began working normally, on the D-Link but it absolutely will not connect to the 2-Wire modem. Evidently it will not work with that router, I cannot imagine a device not connecting to an IEEE standard. All other devices will connect to the 2-Wire router no problem. My PS3 latency actually improved connecting directly to the 2-wire secondary SSID network.
Anyway, what I am saying is that the new iPAD may have some issue with the wireless card. I am still going to send it back, for what it costs, this is unacceptable. For the hours I spent on this, Apple should send me another one for free.
