Android tablet loses Wi-Fi proxy settings
We have Archos 70b and Archos 80 G9 tablets as a trial in the school, and have configured a wi-fi connection on the tablets. They connect fine.
The G9 tablets have recently received the Android 4 update.
The 70b tabs are on Honeycomb.
If I tap and hold the wireless network I created and do Modify, there is a box there to enter our proxy address and port. I do this and save it. I can now browse the net on the tablet and all sites work fine. We have to use this proxy in the school or the net doesn't work on the tablets as everything must go through the proxy.
However, on both tablets, if I disconnect wi-fi and reconnect, it connects fine, but loses the proxy settings I set on the WLAN, as if I never set it in the first place. So the net can't be browsed.
My personal Galaxy SII maintains the proxy fine. Why can't these tablets? Is there anything we can do?
