DHCP lease time

If there is an active connection to the router then the lease time should be irrelevant.

The lease only comes into effect when the device stops transferring data to or from the Router, once this occurs the Clock Starts and when the lease time is reached the allocated DHCP address for the device is returned to the pool for reuse.

Basically if you have a long lease set then the likelihood of a particular device getting the same address every time is increased, if the lease time is short then this is less likely but you will have moore addresses in the available pool.

DHCP leases are important in locations where many devices connect to the network through the router such as business premises, or coffee shops, they are less important in a home situation and so leaving at default is just as good as any other lease time.

It should not affect gaming servers and other services outside of the home network as the IP address and lease for the home address is set by your ISP and they also set the DHCP lease, if you need to keep the same IP address seen on the net most ISPs will, for a charge, assign you a fixed Address

The internal address lease on your local network, can effect the availability of fixed items :- Printers, NAS servers, to the network but this should only be an issue if you only use direct IP access to access these devices, Windows naming conventions will be automatically updated by the Router so should work without issue

 

DHCP lease expiring every hour

I'd be looking at your own modem.... since that device is acting as the DHCP server for your home network. It's typically the DHCP server (the modem) that determines the lease time.... the DHCP Clients (the PCs) don't really control the lease time.

I'd recommend that you consult the modem's webpage to see how you can control the DHCP options

BTW: Why is this a big deal.... I can't image that a short lease would be causing you any issues...
