Newbe question about SG300-20 dropping port to Router
Hello to you all
Today I received my new SG 300-20 managed switch to replace an unmanaged switch with some faulty ports.
I want to use it in a a combined Home / Small Office environment. It is my first purchase and use of a managed switch so am still new at it.
I come from an IT-background but more from the software side than the hardware side of things, but I feel comfortable with hardware and network things.
I was planning to start using the switch in its most basic configuration first and gradually start learning the finer details of its configuration, with the ultimate purpose of setting up several VLANs for business, private use and media playing and to do some IPv6 experimenting.
All my attached devices are Gigabit network capable.
The issue is when connecting the cable to my router (an ISP provided FritzBox 7340 (an ISP version comparable to 7390) which is IPv6 capable) the SG 300-20 keeps dropping the port.
