Challenging story for network geeks...
I have a cat6 cable going from hub 4 to netgear xs508m switch. From switch it is going to old Mac Pro, printer, old laptop - all wired.
If I do speed test on Mac Pro I can see drops in connection, bad speed, slow upload. Laptop same problem when going via switch. Both OK via WiFi.
If I take same cable going from hub to switch and connect with RJ45 Coupler to cable from switch to Mac (basically by passing switch) connection is fast and perfect.
I replaced switch to new one, same thing.
So cables fine, computer is fine, it is something to do with Hub not playing nice with wired switch. Btw I have WiFi router connected to hub and it is fine.
It used to work perfectly!! Nothing changed. VM status of network mentions some problems but WiFi, other wired connection in my home all perfect download/upload. Can it be because of this?
Any suggestions? Ideas? So sad...
