After Upgrading my iPad 3 to iOS 6, i experienced a very slow and unstable wifi performance. This is my hardware setup:
The problem was the wifi standard mode – the router supports the standards 802.11b and 802.11g and offers a “mixed” mode, where devices will automatically choose the right standard. The mixed mode caused the problem, changing the configuration to “g-only” fixed the issues and wifi works as expected again.
It was really hard for me to get the built-in WLAN work properly on the Fujitsu Siemens Pocket Loox 720 – in my case, the pre-installed “E2C” application blocked all Windows Mobile Wlan Functions – if anyone has similar problems, here is how solved the problem:
- The Pocket Loox 720 has a preinstalled Software named “E2C” – this tool should handle all connections on an easy-to-handle interface – the problem is – this software is just a trial version, so you just can setup one wlan / modem / IRDA / bluetooth connection.
- If you need access to different WLANs (like i do), you must not have a WLAN connection configured in the E2C program, because this will block the Windows Mobile 2003 built-in WLAN functions. I desparately tried to connect to my company WLAN for a few hours until i figured this out.
If you can’t connect to a WLAN with “Settings” -> “Connections” -> “Network Connections” always check first, if there is a WLAN connection set up in E2C – if so, just delete the setup in E2C and your wireless connection will work fine.
