-Basically the same as Ubuntu, except I tried with Debian Buster (10).  I updated to Debian Bullseye (11). When I updated to Bookwork (12) the update failed.  I then managed to corrupt the configuration files on the router..... Hopefully these notes expedite recovery.+Basically the same as Ubuntu, except I tried with Debian Buster (10).  I updated to Debian Bullseye (11).

 Having used Ubuntu for the past many years I have grown use to netplan.  This is not native on Debian Buster, so needs to be installed: ''sudo apt install netplan.io''  it basically just seems to work.  Now I have gone back to preferring /etc/network/interfaces. Having used Ubuntu for the past many years I have grown use to netplan.  This is not native on Debian Buster, so needs to be installed: ''sudo apt install netplan.io''  it basically just seems to work.  Now I have gone back to preferring /etc/network/interfaces.

 There are many ways to manually change the computer IP to facilitate this, and this depends upon the operating system and software used by that computer.  A key point is that the assigned manual address and address mask must place the manual assigned address in the same address range as the equipment to be configured.  It may not be the same address.  Say the equipment default assigned address is 192.168.56.34, then the computer must have an address assigned in the space 192.168.56.x/24 (or mask 255.255.255.0), where x is between 2 - 254, except in this case 34, which is the default assigned to the equipment to be configured.  There are many ways to manually change the computer IP to facilitate this, and this depends upon the operating system and software used by that computer.  A key point is that the assigned manual address and address mask must place the manual assigned address in the same address range as the equipment to be configured.  It may not be the same address.  Say the equipment default assigned address is 192.168.56.34, then the computer must have an address assigned in the space 192.168.56.x/24 (or mask 255.255.255.0), where x is between 2 - 254, except in this case 34, which is the default assigned to the equipment to be configured.

 Once the computer network has been manually assigned and network reset check that the network address and mask have been correctly set.  If the assigned network mask is incorrect, that is in most cases not /24 (255.255.255.0), such as /32 (255.255.255.255) it is unlikely that the computer will be able to communicate to the equipment. In linux the following commands can be used to help: Once the computer network has been manually assigned and network reset check that the network address and mask have been correctly set.  If the assigned network mask is incorrect, that is in most cases not /24 (255.255.255.0), such as /32 (255.255.255.255) it is unlikely that the computer will be able to communicate to the equipment.
