Time until DHCP renal.

Assuming you never shut the router off assign a static ip then go advanced > dhcp/dns > static lease time infinite.

DHCP leases the address to a device with a predefined lease time.
In most cases it's 7 days.

At half of the lease time (i think it's half anyway) the device will ask the DHCP server if it can keep the address. 99.99% of the time it'll say yes and renew the lease.
If the device is powered off for more than 7 days, it's address is returned to the pool for allocating to another device.

i forgot to mention sould i disable upnp in the router?

Makes everything work, well I might add. Tomatoes upnp is deliberately limited, no messing with wifi etc, so it should be fine. The only extra security you can give is to switch the ip of the router from the default and use the RAF mod which has the upnp secure mode (devices can only map themselves).

Frankly that's just for the paranoid. for upnp to be exploited something on your lan has to already be compromised which is why upnp isn't a risk. A. The infected device was the risk and B. Home routers outbound firewall is defaulted to allow, if someone's already got a trojan on a pc they're just going to connect strait to the net.

Short answer: Leave it on, keep the Av up to date, download dodgy files at your own risk
