I have 2 iPhones that are having issues keeping a connection with a WiFi network with a WEP key. One phone seems to be staying connected more often, but the other phone just rotates between showing a connection to a WiFi network and then not. This happens every 30 seconds or so. During times it appears that it is connected to the network the "E" is still present in the upper-left corner of the phone. I have already deleted the network profile, turned-off WiFi, reset router, and reset the network into the phone. This did not solve or help the problem. Has anyone else run into this problem/issue with their iPhone. Any help would be appreciated.
