3COM 4500 Switch restarting a linksys router

Hi,

I have an 3COM SuperStack 3 switch, 50 ports, model 3CR17562-91

The problem is that the switch make an rv082 linksys router restart. I changed the switch for another make and the problem is gone.

Is this a know issue? Or is my switch broken? I also have 2 o 3 ports that does not work with dhcp. I have reset all settings to default values.

Any help is welcomed

Many thanks

Oliver
