The situation can be: the router lost the IP address from the Rogers or the router lost the routes in its routing table. Normally the default route in the routing table to the ISP.

For the stuation 1, renew the IP throught the DHCP will regain the IP address.

For the situation 2, reboot the route will correct the problem.

Since the DHCP server from the ISP caches the MAC address for each DHCP request, a renew of DHCP request always gets the same IP address for the same hwarware.

This is the bug of the software and I have the similar experiance with both the Linksys router and NetworkEveryway (which is bought by Linksys now) routers, although the Linksys router will hang once every couple of weeks and the other one hangs every other day.

  • 枫下家园 / 电脑用户 / 奇怪的Router???
    用Netcre的2505NR Router共享 Roger High Speed, 使用了一周,速度还可以,
    但是今天突然上不去了,问了房东后被告知--“将Router的电源线先拔下稍等片刻再插上即可”
    一试果然有效,但是到底是什么问题呢?难道我每周都这么作一次?
    • 死机了呗!
    • I have the same problem with SMC router. This problem happens when the network traffic is very high, reaching the limit of the bandwidth the connection offers.
      • 我也经常碰到这个问题,不知道和Router的Forwarding setting有没有关系?你讲的network traffic 指内网的还是Rogers cable的网络?
        • I mean the network traffic flowing thru my intranet.
          I mean the network traffic that flows through my intranet. I have my mail server running 24x7 and the traffic is quite huge. This will bring down the router that connects to Rogers via its Cable Modem.

          The symptom is that the default gateway does not forward your IP packets to outside. You cannot ping any hosts on the Internet as your ICMP requests cannot be forwarded to any DNS server; even you try directly pinging an IP address, it will not go through because that gateway does not work at all.

          What I am doing is to release the IP information and renew it. Although the renewal gives me the SAME configuration, the same IP and default gateway, DNS, it starts to WORK!! No idea of what's going on....
          • It didn't work when I use 'cmd' to renew and release the dns address. I try to sovle it by reseting the power on the cable modem. I don't know whether it's a correct way.
            • I do not use the ipconfig command but use the administrative web page provided by the router. You can reset your router's settings from an admin console.
    • 哈哈!我来告诉你谜底吧!你一定是用的rogers-hispeed!住的那个区还可以用bell sympatical.
      Roger 是看你们总的下载流量太大了,又不敢掐断,只好偷偷在接入段切断然后重启Router重连就好了。我以前也是用Rogers的。实在受不了了。一怒cancel了换Bell了,就再也没断过。不是你Router的问题!!我另一个哥们,他那个区没有Symppatical.结果Rouges不但一下子断了他的网(注意是一断24小时)还发信警告他,再用P2P软件。立马停止服务!!!他没办法!只好不用了!!!!!
      • 我们曾经被屡次断网,一断就是几个小时,最后一次说要断我们一个星期。一怒之下换成Bell了。
        • We had the exactly same situation. Rogers really suck now.
      • 不能上网的时候ping ping看router
      • Yes. You are right! I think so.
    • 上行杜塞。禁用netbios和ipx协议
    • 可能他们那片的IP地址重新RENEW了,但你的ROUTER没有释放旧的,所以RESET ROUTER来RENEW你的IP(DHCP).

    • Change Dynamic IP Address to Static IP Address
    • 我也被困扰了好久. 终于搞定了.
      我的情况更严重. REBOOT DLINK ROUTER一次, 有时仅能维持2-3分钟. 所有能想到的方法都试过了. 苦恼极了. 正当山穷水尽时, 又试了一招, 终于搞定.

      ROGERS提供给我们的是动态IP地址. 照理说电脑得到的IP地址是会变的. 可
      我发现它一直不变. 难道是ROGERS忘了启动相应的程序? 或是升级Rogers Hi-Speed Internet Software Version 2.0的缘故?

      顺着这条思路, 我把ROUTER的设置由动态IP地址改为静态IP地址. REBOOT, 成了.
      • Good for you!!!
      • No. It will happen next time. It is not a root.
    • 我有这种情况总是reboot cable modem.
      • 最终的解决办法!换bell sympatical吧!
        • I'm afraid Yes.
