PC won't connect to Internet until I reboot the router - every morning

[PJG81]

Apologies if this has been dealt with before, but I haven't been able to find a solution by searching. I have a Sky router connected by ethernet cable to two Windows 11 PCs, and usually there is another Windows PC connected on WIFI and a couple of smartphones. When I turn my main desktop PC (Lenovo Thinkcentre) on in the morning, it won't connect to any websites until I reboot the router. Using my other PC (Surface, with docking station for ethernet) there's no problem with connecting. Nor is there a problem when using wifi. I could believe that it's a problem with the Lenovo, except that rebooting the router solves it every time. Any suggestions welcomed!

@PJG81 as a guess I suspect that when the problem PC comes on line it doesnt  get an IP from the hub's DHCP server. It could be an oddity of the network settings on that unit or a timing issue but as a workround if you reserve an IP address on the Hub in its web interface and set that as the fixed address on the PC that should work.
