Hi,
I am having problems with connectivity. I have a LAN that is splitted in 2 segment, segment 1 has 12 PCs and segment 2 has 14 PCs. Both segment are joined through a switch, 16 port each.
|PC1| |PC2| .... |PC12|
------------------------ | | ------------ |switch 1 | ------------ | | | ------------ |switch 2 | ------------ | |
------------------------ -------- |PC1| |PC2| .... |PC14| |SERVER|
The problem is until yesterday all were working OK, but today the PCs on segment 1 (switch 1) can not connect to server, neither between them. If I turn off switch 1, and turn it on, I have connection but only for a few seconds and then there is nothing again. If I put a old hub replacing the switch 1, everything works fine. I have tested 2 switches with same results, and I have checked the wired and seems everything allright.
What is going on? Maybe electrical interferences ?
Thanks in advance.
