I had a network consisting of a Ziggo modem with an Archer C7 attached to it. The Archer had on its port a PC and an Synology NAS.
After introducing a M5 after the Ziggo Modem and reconfiguring the C7 as switch (No WIFI, no DNLS) I cannot use the PC wired. It functions flawless thru WIFI, the access to the NAS is also WIFI.
On my laptop I havre internet but no access to the NAS.
Everything functions under W10
What did I do wrong?
