Hey all,

I have purchased two TL-SG108s to run in a chain. I know these are unmanaged switches, but you would expect them to be smart enough to see each other as Gigabit connections, and use the maximum they can.

Here's my situation.
I am connected from a Router to a switch room. Router => #1 SG108 --- This recognizes the Gigabit port from the router.
The #1 SG108 connects thru to another room where I have #2 SG108 --- This only recognizes the port as 100MBs
My computer in the same room as #2 sees it as Gigabit, but the connection to the other SG108 slows it down, due to it's 100MBs uplink.

I disconnected the #2 switch, and connected directly from the computer to the wall -> #1 SG108. This recognized as 1GBs speed.

I was able to confirm the speed differences using SpeedTest. I have a 105MBs connection from Comcast.
When I connect directly from the Computer thru the wall cabling to #1 SG108, I get 125MBs speeds. Really nice.
When I connect from Computer -> #2 -> Wall Cabling -> #1, the speed drops to 92.

Does anyone know why these switches would not see each other properly and use max speed? Is there anything I can do to change this? The fact that they are not managed suggests there is nothing I can do. However, that is pretty bad if you can't chain these Gigabit Switches together w/o seeing the maximum throughtput between them.

Thanks in advance!
