Hi all- Need a little expertise if anyone has a test/solution to my iPhone 4 WIFI woes at home. Details: I have an AP Extreme base station set to WPA2 (working for 1+ years) dual band. I have (2) AP express stations to extend my network throughout my home (1 is primarily used as Airtunes only to drive my stereo speakers throughout the home.) The second is located in my sons room at another section of the home to extend the network out in the back yard/deck of the home. Distance between the APE and APX is about 75 feet. All stations are set to WPA2 protocol I have a guest network as well. Problem is the following: iPhone 1st gen/ and iPhone 3GS have no problem keeping a connection whatsoever on the network within a 50-70 foot range of my house, nor the deck which is literally right outside the door in the back, not to mention about 20 foot from the Airport express in my sons room. On iPhone 4, I loose connection (finds network but will not connect) then shows an invalid ip for my network.-->See photo 1 below. My network address/ip for the phone is reconnected when entering the home and getting close to the base station, it joins it again automatically. See photo 2 Photo 3 represents turning WIFI off on the device and back on, showing the strength of the connection outside, yet it will not connect with the proper IP, only the invalid one. Whatever I try, resetting network settings, forgetting network, trying to rejoin- it accepts connection, yet remains on 3G until the home is entered again and is close the the station. Anyone who has some tips for me to try, I would be thankful for your efforts. Any details further that are needed just ask in case I left out some important information. Lastly: the phone is in a case, and I am not having the antenna issues: in my area anyway. Thanks in advance for any and all assistance!!!
