Why can't I access some wireless networks which are not se..

I can access many wireless networks that are not secure but at a truckstop I
found a strong unsecure network which allowed me to connect but I could not
send or receive data on the internet. They probably have a fee for their
service, but how does it work? What do they give you that allows you to use
the network?

Did you open a browser? Did it give you a login page?

It could even be as simple as they didn't have a default gateway defined
at the router or as simple as "allowed hours" and you weren't in the
allowed range.

Normally, with a hotspot, you open your browser, get redirected to a
payment/login page, you do this, then you continue.

First of all, hopping onto someone else's network and trying to use it
just because it isn't secure is something you really shouldn't be doing
unless you've gotten authorization in advance from the entity that owns
the network to do so, or at least know that the network is provided for
public use (and can prove this to someone else if you have to). These
days, it's becoming more and more likely that such adventuresomeness
could land you in hot water legally. And with legitimately available
free Wi-Fi becoming pretty much ubiquitous, there's really no reason to
do this any more.

Assuming that the network you found at the truck stop was there as an
open public hotspot, the thing to determine would have been whether or
not it gave you an IP address. If it didn't, it may have been down at
that time, or have been having other issues. I'm assuming that since
you mentioned that you've used a number of other networks, you know that
generally you have to have your TCP/IP set to use DHCP so that your
computer obtains an IP address automatically.

If the network was "play for pay," then when you tried to go to your
browser's homepage or any other URL you should have been redirected to a
login or registration page where you would have been able to make
payment arrangements. Some free hotspot operators have gone to
requiring a purchase as a condition of access, but again you should have
been redirected to a login page, or the network would have been
encrypted and you would have been given the key with your required purchase.

I'm inclined to think, however, that you encountered a network that
while unencrypted really wasn't open to the public, and you didn't get
full connectivity because they were using MAC address filtering. Just
another way for whoever was riding shotgun on that network to suggest
that you mosey along, pardner, and see if maybe you could rustle up some
legal free Wi-Fi in the next town.

I don't remember opening my web browser. Maybe it would have shown a log on
page.
