Almost, RJ-45 is the specification for the plug and jacks, what you're
having here is ethernet wiring in twisted pairs between client and
server connected by a hub. Or switch, please clarify that as that
changes a lot.
Is anything else connected to this hub? If your problems occur, is
anything else using the hub concurrently? Can you reduce the
connections only to server and client and maybe a internet uplink?
Network printers can do unimaginably bad things in regard to hubs, and
even switches.
Can you change the hub to a real switch?

Perhaps. Check the "ifconfig" output on the Linux side, maybe reset the
server, connect from windows and if you're having problems check the
dmesg output regarding the interface.
For reference, here's my output:
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 217.172.177.159 netmask 255.255.255.0 broadcast 217.172.177.255
ether 00:19:66:f1:43:9e txqueuelen 1000 (Ethernet)
RX packets 81994186 bytes 14753508445 (13.7 GiB)
RX errors 14 dropped 0 overruns 14 frame 0
TX packets 107524155 bytes 14836289080 (13.8 GiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Take note of the 2nd line of RX and TX status lines, there should be no
counters there, in my case 14 overruns in regard to 819 million packets
is a very low error rate. I suspect that if there's a network problem
it would manifest in some higher relative values on your side.
If in doubt verify that both sides are set to auto-negotiate and replace
both wires from the machines to the hub with new cables.
