I have an irritating speed issue in my home network.
My network has gigabit switches like this:
Switch 1 <- Switch 2 <- iMac 1, iMac 2
Switch 1 <- Switch 3 <- Mac Mini 1, Airport Extreme
Switch 1 <- Mac Mini 2
All Macs are manually set to 1000BaseT in their respective network settings, and that seems to be working.
To test the network speed, I’m running Speedy Net on the four Macs, and any traffic not crossing the Switch 1 / Switch 3 boundary goes up to about 700 Mb / sec. If I cross the boundary between those two particular switches, I only get 87 Mb / sec. Copying large files from Mac Mini 1 to Airport Extreme "within" Switch 3 is consistently quick as well.
Switch 1 is in the basement, Switch 2 is in the study and Switch 3 is in the living room. The cable between Switch 1 and Switch 3 is shorter than between Switch 1 and Switch 2. Mac Mini 2 is upstairs and has the longest cable between it and the switch. Even the longest cable isn’t particularly long, 20 m tops.
I’ve swapped out both Switch 1 and Switch 3 for a couple of other ones and tried different cables and ports (not all combinations). Currently I’m using three brand new NetGear switches, but my previous Switch 3 was a Zyxel, and according to its led color, the port connected to Switch 1 was only operating at 100, so that seems to be the problem, although I can't understand why.
What could be wrong here?
Cheers,
Kim
