I work in a 30 workstations company.
I've replaced an old hub on which every one was connecting at 100M / Half duplex for a brand new Allied telesys gigabit switch model AT-GS950/48
Everything seemed to be working fine, but some users began complaining about slow startup time of a network application.
Upon investigation, I discovered that every workstation connected at 100M Full (or below) gets very erratic connection speed, moving from 6Mbytes/sec to under 300Kbytes/sec, back and forth all the time.
Gigabit connections on the other hand, gets very stable speed over 30Mbytes/sec.
The Internet connection is going through a pfSense router which is splitting it in 3 VLANs.
The switch is in production now, so I have little lattitude in terms of testing. Any idea what the problem is?
Thanks in advance.
