I have problems with switch SG300-20. The switch is connected to a AVM FritzBox.
Configured are fix and dynamic (DHCP) IP Areas (see attachment) in the FritzBox.
Following issues occurs.
The devices with dynamic IP's get not a valid IP-Address after restart.
The devices with a fix IP-Address get also not Internet access after restarting, but I can fix the Problem when I disconnect-connect the Network cable between FritzBox and switch.
In the past a Cisco certified Partner has looked to the switch configuration but can't help me.
For my opinion it is a configuration Problem, can you give me a tip to solve the Problem please.
Currently I have installed a old Netgear switch (Fast Ethernet), it works in the same configuration propper.
Many thanks in advance.
