Happens frequently on our two Pre 2s. Suggestion: When our phones do profile backups to the Palm servers out on the net, could this be the event that initiates the problem? ...I notice the problem most often at night, the phones idle on our touchstones.
Note: I have had serious problems with these servers ... they are no longer well maintained. I needed a replacement Pre 2 over Thanksgiving, but the new phone couldn't load my profile for days .... had a Verizon techie on line for hours trying to complete the activation .... AND HE couldn't reach anyone at HP to get help.
After the holidays, ...still no response from HP.... I gave the new phone another try and it loaded my profile immediately and has been running perfectly ever since.
Last summer, both our phones would chew battery power like crazy.... I got new batteries and that didn't help. I gave up and used an old phone for a few days on a trip, when we returned home, the phones were back to normal and we had no repeat of the problem ...I never needed the old phone again and just recently deactivated it.
So here is the hypothesis: our phones do their normal thing and try to backup; HP has cut way down on the support of the profile backup server shop; they get saturated, and the support staff tried to sluff off load. Some junior programmer hack in that shop redirected some percentage of what should have been a simple disconnect to the server for the hp palm page we see. The WebOS 2.1 Captive Portal sw realizes the connection didn't go where it was intended, assumes it is a captive portal event and pops up the notification.
This make sense to anyone?
One of the magical things about smart phones is the invisible interaction with "the cloud" .... which sometimes can lead to battery draining busy loops if the servers do no provide the intended response. This is not unique to WebOS, but first seen on our webOS phones because Palm was one of the first to use "the cloud" before it was called a cloud, to store significant data.... e.g. when my replacement Pre 2 came up, not only did it know my accounts, buy my ***extensive*** memo notes were all restored to the new phone!
....why were these memos not also downloaded when I got my TouchPad and logged into the same Palm account is beyond me. ...probably just one more of the many good ideas the developers had but never implemented.
WISH: ....please, someone who has contacts into the HP server farm supporting profile backups, ask if this could be their problem.
Alternative: ...please, someone give me the directions on how to check the logs in my phone and track down what was going on when the "captive portal" notice was sent. ....that is the first step to properly diagnosing this problem IF it is related to the backup service (or some other service running on our phones.)
