As background, my droid logs in just fine to wifi hotspots as long as signal is good. Typically at work, I turn on wifi on the Droid, then open my browser, and accept the certificate. Similarly, I am at a conference in Brussels, I turn on wifi, choose the server, and then open the browser to log into the Cisco webpage that pops up (username and tedious password).
My problem is that when I either lose signal to wifi or if I have a good 3g signal (such as when I come out of the iiner corridors at work to a peripheral area), the phone or Cisco 'forgets' my phone. Then I have to open the browser and re-login or re-accept the cedrtificate. This is a pain, since I lose my connection and will not update email or provide instant message updates until I log in again.
Is there a way to lock the wifi to prevent the rutine cell signal from bumping wifi (like at work) or to retain the previous login?
