The first thing to do is upgrade this hub to 100 base T -- I dont know what country you are in, but these are available in the US for less than $50 for a 25 port hub, and you probably want 2 of them.  Is that too much to pay to get your speed up to a workable range?

The ACT light will blink whenever traffic is going on the network, it will probably blink constantly for you, same on the hub, both lights will blink on both ports where traffic is coming through.

Spend some money on a couple of 24 port 10/100 or 10/100/1000 switches, they don't have to be fancy if your budget doesn;t run to it but get the server onto a 100 full duplex connection or ideally gigiabit if the card supports it.  Watch all your network issues go away.

If you are really using a HUB, then your network is pretty congested. A Hub distributes data received to all machines that are connected to it. That means a lot of unnecessary traffic. If Machine A wants to talk to B, then C, D, E, etc. get all the data as well (they will discard it but the traffic is just there). Replacing the hub with a switch will alleviate the situation dramatically. A switch keeps track of which machine is connected to which port and will send data only to the port that is connected to the destination machine. This measure reduces network traffic quite a lot and improves performance on network and machines. It is not even necessary to switch from 10 MBit to 100 MBit or Gigabit to notice the effects. If your network is of poor cable quality, switching to 100 MBit (Fast Ethernet) can even have adverse effects. The main point is to move from HUB to SWITCH.

P.S. Just saw that you mentioned a model and it really is a hub. Replace it with a switch and everything will be much better. The Hub means half-duplex communication - only send OR receive at a time, and only ONE sender at a time. With a switch, EVERY connected machine can send AND receive at the same time (up to the line speed limit, of course). You can imagine that this improves the network performance very noticably.
