Apparently, you have an older 5-port hub. The ports labeled 1-5
are identical. The connector labeled "uplink" is wired to the port
physically closest to it (either 1 or 5). The uplink connector
just has receive and transmit reversed, so plugging a crossover
cable into "uplink" is the same as plugging a straight-through
into its companion port (the one next to it) and vice-versa.
You can use either the uplink port or its companion, you can't
use both at the same time.
Most likely your cables are straight-through, though there is
a remote possibility that the cable from your existing modem
to your computer is a crossover. I'd recommend that you use
that cable to connect your modem to your hub. Plug that cable
into the "uplink" connector. When both ends are plugged in
and powered up, if the lights near the connectors on your modem
and hub light up, all is well. If the lights don't come on,
unplug the cable from the uplink connector and plug it into
the connector physically closest to the uplink connector.
Then, connect a cable from one of your computers to one of the
remaining ports on the hub. Again, if both ends light up,
all is well.
No damage is caused by plugging in a crossover cable where a
straight through is needed; it just won't work (no lights).
Good luck.
