Frequent DHCPREQUEST from hackintosh machine and network loss every 13-14 seconds.

The problem lays in the combination of my router (GL.iNet GL-B1300) and the hackintosh machine (m710q i3-7100T)
While everything starts and works with my secondary router (ZTE) this machine refuses to properly interact with my main router
Wifi conntection to the main router is not possible - the machine cannot connect.
Wired connection drops every 13-14 seconds for another 3-5 seconds
I need any assistance because it drives me crazy...
I can't replace my main router right now.

It looks like this in the router logs Fri Mar 8 11:04:28 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:04:28 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:05:13 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:05:13 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:05:57 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:05:57 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:06:41 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:06:41 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:07:26 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:07:26 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:08:10 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:08:10 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:08:55 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:08:55 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:09:39 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:09:39 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:10:23 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:11:08 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:11:08 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:11:52 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:11:52 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:12:36 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:12:36 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:13:22 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:13:22 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:14:07 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:14:07 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:14:52 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:14:52 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:15:36 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:15:36 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:16:21 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:16:21 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:17:05 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:17:05 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:17:49 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:17:50 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:18:33 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:18:33 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:19:18 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:19:18 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro Fri Mar 8 11:20:02 2024 daemon.info dnsmasq-dhcp[14517]: DHCPREQUEST(br-lan) 192.168.0.170 6c:4b Fri Mar 8 11:20:02 2024 daemon.info dnsmasq-dhcp[14517]: DHCPACK(br-lan) 192.168.0.170 6c:4b iMac-Pro
