It is a hub. I have a router that has 4 ports but is maxed out. I want to add more machines to the Network and someone gave me this hub. How do I use it? Thanks
Plug it into one of your router ports. Next plug the cable
(system) that was plugged into that port, into the hub.
Check the link lights to confirm the connectors are good.
If you wanted to do it the safest way, power down the router
and hub first then power them on again after replugging the
cables. As it relates to your other thread, you would then
plug your other equipment into another hub port.
However, my prior suggestion about a switch was made under
the presumption of semi-modern equipment, because 100Mb
switches have been common for several years now. The hub
you linked is only capable of 10Mb which will be faster and
more reliable than a wireless 802.11b connection, and still
more reliable than a 802.11g connection, but not necessarily
faster if even as fast.
Not all people need 100Mb worth of throughput though, since
you already have the hub you might try it, and if you find
it's too slow for any particular use then seek an
inexpensive 100Mb-capable switch, which might cost anywhere
from $0 (after a rebate) to $40 (usually less).
