iPad Dropping WiFi Connection

[MikePA]

No, it's not the old problem. I did a search and didn't find anything.

iPad running stock 4.2.1.

I connect to my AP at home and stay connected. No problems.

At work, we have a wireless network that has access to the Internet only, not our internal network. We control access to this wireless network using Cisco 'hoteling' software which requires you to authenticate via a browser. No other security, e.g., WEP, WPA, etc. This connection is used mainly by guests, contractors, etc.

When my iPad display powers down, soon thereafter, I lose connection to this wireless network. The odd things are;

1. Some times there's still the wireless 'icon' in the upper left hand corner.
2. Settings---WiFi still indicates I am connected to the wireless network.

But no application can get to the Internet. I have to go into Settings, turn WiFi off and on again to trigger the Authentication process. Why?

I did check with the people who manage the Cisco software and they drop any connection that's been inactive for more than 2 hours, but the problem I am seeing seems connected to the display going to sleep.

That means you have local access to the router. The presence of the WiFi icon doesn't always means you have Internet access. In this mode, you can change the settings of the router provided you have administrative access. Go to the WiFi's SSID and touch the blue arrow. Do you see 192.168.x.x? Or something else when you can't connect to the Internet?

I don't have access to the Cisco AP, so I will have to ask the people who do.

Just look in the blue arrow part of the WiFi you're connected to. Look at the subnet and IPs. Tell me what they are.
