このようにネットワークの設定を確認してほしいとのこと。
確認したところ、ルータにpingは通ったのですがgoogle.comには通らなかったです。
routeを確認する。
route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.11.0 * 255.255.255.0 U 0 0 0 br-lan
/etc/resolv.confを少し触ったのでこのような状態になっています。
解決方法
デフォルトゲートウェイが設定されていないので追加します。
# route add default gw 192.168.11.1
# route

最後に
いろいろ調べたのですが、openwrtに関する記事が少なかったのと、比較的基礎的な部分(openwrt関係なかった)の失敗だったので備忘録として残したいと思います。
ネットワークの知識は皆無なので間違ている個所があればご指摘のほどよろしくお願いいたします。
