My icx 7150 has developed odd behavior of a lag spike and even hooked up directly only allows @ 350 mbs thru put up or down. This occurs even when directly computer is directly plugged into switch. The modem and router verified thru put is 1gig byte per second. I complied all the flash flash verifying the proper file load and several other recommended actions, but still the same effect. The switch use to provide much higher thru put. I have read that this has been diagnosed as a switch component failure? What do I need to do do correct this issue?
