open wireless access arbitrariness

We have an open wireless network at work. By 'open' I mean that no login is required. Typically, I'll bring in my tablet, open Chrome, which is directed to a page with legal jargon about how you promise to be good etc, you click OK and then you're in. On some mornings however, internet access just happens. This works for like 1/2 hour and then it stops working. So I go open Chrome, which opens the legal page, and I click OK and I'm in again.

Can anyone explain why this happens? I'm curious how it is that it can sometimes work for a little while without having to 'login' and then stop working and force me to login.

What kind of wireless system do you have?
Most likely, you have some kind of "reauthenticate after 30 minutes" settings ---

depending on you system, it might be that you have a DHCP lease of 30 minutes, and you might reauthenticate when lease ends ... most likely not, and depending on system - but is in any case an easy thing to verify

Once on, it will stay connected all day. So I think that it doesn't require re-authenticating after 30 minutes. Re-authenticating every 24 hours (from one morning to the next) would make sense, though.

- What system do you have?
- Do this happen to alle users?
- if not? how many? are there any similarities among users?

I'm just a user. I don't know if it happens to everybody.
