無線路由器(SMCWGBR14-N)常常當機?

我的路由器記錄檔中不斷(3個月..)收到這樣丟棄封包的狀況(從這一台開始使用不斷出現)，
懷疑是無線路由器有時候當機(無線路由器的燈號不斷再閃動，但是突然有線與無線的設備都斷線)
的原因，
可以設定Routing 去排除這個些嗎?
或能否提供建議的處理方法!

Wireless router: SMCWGBR14-N
Intenet: 凱擎大寬頻，Cable
有線設備:2台(Desktop, windows 7)
無線設備:4台(Notebook, Mobile phone, Ipad)

只是很單純被操爆了而已吧?
上面的訊息,大多只是很單純的,對某個連線要做啥事,但是那個連線根本不存在,所以Block掉
或者是連線時間過長,那台認為這個連線早就沒了,Client端卻送了個RST...

感覺上沒啥關係,反正韌體記得更新到最新的看看

SMC的……要更新有點難……
1、看看有沒有得更新？
2、Reset重設
3、拆殼散熱
4、尋找下一台

謝謝你的回覆，
但是
1. 由這些紀錄可以看到外面的連線傳到內部無回應的錯誤，
目標是大量的[B]123.192.231[/B].11:56013 這樣的電腦位址，
但是內網的IP只有192.168.2.* 這樣的名稱，
這樣是是什麼狀況呢?
2. 記錄中，幾乎是一分鐘內超過20次的回覆無連線的狀況，
這樣不是正常狀況吧!

外面的Internet,只會知道你的外網IP
也就是說,別人的TCP or UDP封包的目的地,一定是IP分享器的對外IP
如你的例子就是123.192.231.11

但是連111.221.72.82:[B]443[/B]的來源連線都有,這...有開QOS?關掉試試??
有4662,表示你有在掛驢子一類的...

更新看看吧? Release 01/29/2010 SMCWGBR14-N Firmware v1.0.10.2

或者是你有限制了啥連線數或連線逾時時間?
不然就如Alan兄說的,
2、Reset重設(先更新完再重設)
3、拆殼散熱
4、尋找下一台

是不是有設定連線數限制? 如果有，設大一點數字，或是關閉限制連線數功能。或是 連線數過大，超過 AP 限制。

謝謝兩位高手的見解，
我試試看在回報。

透過這路由器連網的設備很多嗎?
所有連線的使用者都移除，還會這樣嗎?
我曾有的經驗，某網路設備故障，導致一堆連線。
或是....因為是無線的，有人利用他連線?
