1812Jが壊れてしまったので、新しくルータを買い直しました。
後継機種の892Jです。
1812の時のようにIPの設定とIOSのバックアップを行いました。
今の設定は以下のようになっています。
Cisco892J#show ip int brie

1812Jとの相違点はIPアドレスが違っていること以外には、下記の通りになります。
ホスト名の設定
Router(config)#hostname Cisco892J
Cisco892J(config)#
パスワードの暗号化
Cisco892J(config)#service password-encryption
DNSサーバの設定
Cisco892J(config)#ip name-server 192.168.179.1
時刻の設定(確認、タイムゾーンの設定、NTPサーバの指定、時刻合わせ、確認)
Cisco892J#show clock

Cisco892J(config)#clock timezone jst 9

これでようやくネットワークが本復旧できました。
