Additional Behaviors Surrounding Captive Portals
Although recent operating systems detect captive portals,
this feature can sometimes be disabled in their settings.
When started manually,
most browsers should detect and redirect to the captive portal,
but again, this feature can be disabled as well.
All of this is true for smartphones too.
There are a few different unusual behaviors regarding captive portals,
which we might encounter and should aware of.
For example, Windows will not show the captive portal
after automatically connecting to the network.
In this situation the user has to manually go into the network list dialog again,
select our network, and click Connect for it to work.
We should also note that Chrome doesn’t automatically check
for captive portals upon startup.
It only detects them when manually typing a URL or performing a search.
