|Yes. Most of it is Cat5.|
Cat5 or Cat5e?
There is a difference. Cat5 was never spec'd for 1000 Mbps (gigabit) whereas Cat5e is.
I'm told you can use Cat5 for 1000 Mbps but only in very short lengths. Personally, I wouldn't try to carry 1000 mbps on Cat5.
So if the cable in your walls is Cat5, you might want to give serious thought to upgrading it to Cat6.
Checked my router. It has T100
I'm not sure what you mean by T100 or what it references. Does this mean the LAN ports on it are 100 Mbps? If so, that would definitely slow things down.
Wanderer is correct about daisychaining switches. The reason you don't want to is that the bandwidth aggregates. Which is to say if you have 3 switches, 2 plugged into 1, and 3 plugged into 2 then you end up with the following:
- switch 2 carries the sum total bandwidth of switch 3 AND itself
- switch 1 carries the sum total bandwitch of both switches 2 and 3, as well as it's own.
Typically in industry we avoid daisychaining at all costs. But we deal in hundreds and thousands of clients and their bandwidth, not 10 to 20 which is not a whole lot in comparison.
However, it may be necessary for you to daisychain in your particular instance. If your router is maximum 100 Mbps to the LAN ports and you plug both your switches into it, any/all communication between switches would slow down to 100 Mbps. So if client A on switch 1 has to communicate to client D on switch 2, they pass through the 100 Mbps LAN ports on the router and that's your bandwidth for the communication.
Conversely, conversation between clients on the same switch should remain 1000 Mbps as long as they all have 1000 Mbps NIC's.
So, to sum up, you have two options if you want all LAN communication to be 1000 Mbps and the LAN ports on your router are maximum 100 Mbps.
1) Daisychain switch two into switch one. Switch one being plugged into a LAN port on the router
2) buy a third switch. Plug it into a LAN port on the router and plug switches 1 and 2 into it.
Option 2 is reasonable since if you don't plug any clients into it, it will only carry the bandwith of 1 and 2 and their clients only. This is essentially what the router is doing now, only if the router is 100 Mbps, it's doing it 10 times slower.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
