DHCP Table

is there any way to edit the DHCP Table when a device isnt connected?

 

i have IP's taken up by devices which i no longer own, since they are not connected to the network i cant figure out how to release the IP's and clear the DHCP Table

 

any help would be nice

Thanks

Re: DHCP Table

They may eventually expire, but the home hubs are not very good in releasing IP addresses from the pool, which is why people have so much trouble. The only sure way is to factory reset the home hub.

Re: DHCP Table

i have changed the release time to 1 hour but still no joy, which idiot disgned a router that you can't release the IP's from DHCP manually?

 

in the Netgear DGN2000 i had before on a different ISP i could click on DHCP and have the  list in front of me, i could add,edit or delete all of them from there

 

i cant even save a backup of the config file and edit it because its encrypted, who ever designed the interface for this router needs to be fired

Re: DHCP Table

Its the same with most of the home hubs apart from the early ones, where you could delete a device and it gets removed from the configuration.

What tends to happen over a long period of time, is that all of the  IP addresses get used up, and nothing will connect unless it has a static IP address.

Only a factory reset fixes it.

The same idiot that designed my TP Link I guess, you can't release them on that either.

Re: DHCP Table

I prefer using static IP addresses outside of the DHCP range, and just leave DHCP for roaming devices.

 

But I do not use the home hub DHCP server, but one that is within one of my wireless access points. That also allows me to specify different DNS servers.

Re: DHCP Table

It does release addresses when the lease expires though.
