I ran into a strange issue yesterday when using an MS130-24X plugged into a Spectrum Internet router.  If I plugged my PC directly into the Spectrum router, I got full speed (930/35).  If I plugged my PC into the MS130-24X which was also plugged into the same Spectrum router, I got really bad upload speeds (350/0.7).  After troubleshooting for awhile, I finally moved the connection from the Spectrum router to a NON-2.5G port, and I suddenly got full speed with my PC connected to the MS130.  I checked, and it properly negotiated 1G full duplex when connected to a 2.5G port, but had completely borked upload speeds.  Is this a known issue with the MS series switches 2.5G ports?   I first noticed this issue due to bad upload speeds when wirelessly connected to an MR57 connected to the same MS130, so it most certainly was not an issue with my PC's NIC.  Moving the Spectrum link to a 1G only port resolved the Wi-Fi issue as well.   ...
