I'm experiencing frequent internet outages at home, around 4-5 times a day, and it seems to be linked to my Synology NAS. It's directly connected to my internet modem, and I've set up port forwarding, enabled external access in the DSM, disabled the firewall, and adjusted settings in the static DHCP for my home network. I even tried adding a switch between the modem and the NAS, but the problem persists. The internet restores immediately when I unplug the NAS. I'm wondering what might be causing this issue and how I can resolve it.

You might want to be careful with turning off the firewall and allowing external access to your NAS. That can open it up to potential hacks. It seems risky, especially with how your NAS is behaving. Consider re-enabling the firewall to tighten security.
Make sure there's only one DHCP server on your network. If there are two, that could lead to lease renewal conflicts that might be causing your internet issues.
Exactly! It sounds like your NAS could have been compromised and is hogging your bandwidth, which explains why the internet works again when you unplug it.
