Ever since I've upgraded my my iPhone to 4.3.5 and my iMac to 10.7.1, I've had weird issues with connecting to my wifi on my iPhone. I have an AP extreme. I am not very wifi savvy so I am hoping someone can look at this and let me know whats going on.. As you can see in the pictures, my iPhone is saying its connected to my home wifi..Just as it always has. But if you notice, it is still showing the connection as 3G. And the network info shows only the IP address and the Subnet Mask. No router or DNS. I've run speed tests and it's definitely on cellular data and not wifi. My iPad2 had some weird issues initially but it now connects to "sulps home" 5ghz band with no problem. But it still has issues connecting to my regular "sulps home" 2.4ghz that i usually use. iPhone keeps asking for my password over and over and never connect. If it does seem like it finally connects, the above pics are all i get. None of these issues existed until i upgraded both my mac and iPhone (which I did one after the other). So I don't know which upgrade (if any) caused this. I done power cycles, cleared pram (per advice from a friend), renewed leases, and anything else I could think of (which again isn't too much). The weird thing is that I have another all in one wireless router/switch that I use for my Vonage land line. I couldn't disconnect it because my land line uses it and it happens to have a wireless router built in. I have that network (DLinkVWR) unsecured and let guests use it. My iPhone connects to that network (DLinkVWR) with no problems and works perfectly. I would really appreciate it if someone could help me! its driving me nuts. If there is any other info needed to diagnose, please let me know and I will post it. Thanks all!
