コレガ CG-WLBARGPXB-P 無線LAN ブロードバンドルータ
修理に出して、商品が交換されてきた「CG-WLBARGPXB-P」製品情報 株式会社コレガ修理に出している間にインターネット回線がYahooBBから光に変わり、現状使っていなかった。
久々に、これをCTUに接続して、インターネットをすることに、現在、プロバイダーは、2回線契約しているので、CTUにT社を設定している為、ルーターにPPPoE接続で、E社を設定することに、ルーター上は接続中なのに、インターネットが出来ない。???
とりあえず、NTTのサポートに電話するとCTUは、MTUを1438以下にしてくださいとのこと、早速,MTUを1438にする。やはり、接続中の表示は出るが、繋がらない。
再度、サポートに電話するとMTUをコマンドで、調べてくださいとの事、MTUを調べるソフトもあるが、サポート出来ないのでソフトは、教えてもらえなっかたので、
コマンドで、調べることに、
ここからは、結果としては、むなしい努力でした。
見たいかは、どうぞ。
