Security of Wi-Fi networks
Avoid moving DHCP to your Synology device, and turning it off doesn’t really help much… anyone familiar with PCs can simply assign a static IP, which is essentially the opposite of what you’re trying to fix. If this problem recurs, someone on the network might be downloading torrents, I can confirm that.
If they can break WPA2 encryption, you won’t be able to stop them or track their activity. I assure you, if your password has changed yet they’re still accessing your network, it’s likely someone in your household or someone you’ve shared the credentials with is involved. Or perhaps your password is weak and predictable. The only real way into your network would be through physical connection—like a hidden switch or an unknown Ethernet line. Extending the lease won’t make much difference; at most you’ll get a MAC address, which implies all your devices are already configured statically and you’re searching for an IP you didn’t set yourself. Even then, if someone can crack WPA2, they’d likely erase router logs, fake MAC addresses of existing devices, or perform other actions I’m not aware of.
I received another alert, but I reviewed the software on the networked machines. The app "Citrus Uptater" stood out. No other programs were visible, yet that device seems unsuitable for gaming, so it’s likely the culprit. It appears a virus may have bundled Citris updater during installation because it’s hard to remove. To fix this, I had to reinstall the system. Additionally, I added a premium antivirus for added protection.
Are you certain the emails come from your ISP? If yes, would you mind sharing them here? IF YOU DO, please keep any personal details private. The concern arises since it seems unusual for your ISP to claim someone used their connection to install a game. I’m not very familiar with Glasswire and suspect it doesn’t function as you believe. It can’t identify or track traffic from other devices. I could be on the same network as you and still run a torrent, yet it wouldn’t appear on your system using Glasswire.
