We have recently bought a 1->36 LAN hub but we have very frequent disconnection for all the computers linked to it.
Our LAN mapping:
Internet->Modem/Hub->LAN router (the one with problems).
It doesn't have any brand on it unfortunately.
Any tips about the situation?
Do you also experience the disconnect when on LAN only (without the internet)?
the first thing you need to know is if the issue is present on LAN without the internet
1. remove the internet from the equation (disconnect the modem)
2. Do a continuous ping from you local network from command prompt
PC1 will ping PC2 - ping 192.168.0.3 -t
PC2 will ping PC3 - ping 192.168.0.4 -t
PC3 will ping PC1 - ping 192.168.0.2 -t
if the disconnect is present on LAN then it must be your HUB or a faulty UTP cable.
3. You may isolate the issue by testing the PC 1 by 1
connect PC 1 and 2 only then do a ping test - if the connection is good then try connecting PC1, PC2 and PC3 then do a ping test and so on so forth.
It is possible that if there is one faulty LAN or cable it can cause a disconnect on the their network.
I can keep on going but I think I made my point - If you need further clarification please let me know.
