I can't really tell what's going on, but I have a guess. You probably
saved a "profile" or something similar when you connected to the
library. Delete it and your laptop will pretend it's a new connection
and start over with the settings. It's probably something the library
changed, and is different from what you saved.
The failure to renew is a good clue as it means that you have a saved
IP address from a previous session. That probably means that the
library system has saved your MAC address from a previous days session
but has given out that corresponding IP address to someone else in the
meantime. It can easily be cured by having the library power cycle or
reboot their wireless access point, but i doubt they'll do that for
you. What really needs to happen is to have them shorten their DHCP
lease time to perhaps an hour instead of a day.
It's also possible that a similar problem was created on your laptop.
If you use the hibernate or sleep mode on your laptop, by simply
closing the lid, going home, and coming back the next day, you'll find
that it still has the previous days settings. These settings may or
may not work depending on how the library router DHCP lease is
configured. The best suggestion is to reboot your laptop. If that
doesn't work try:
Start -> Run -> cmd <enter>
ipconfig /flushdns
ipconfig /release
wait about 10 seconds
ipconfig /renew
That should do the same thing as a reboot but doesn't always work.
