我的网卡怎么了？为什么不能上网？

zzmv00

系统是Centos x86_64,安装好后配置网卡和adsl都没有问题，拨号后也能获得外网的IP地址
但就是不能浏览网页,无法解析主机,直接输入IP地址也不行，ping外网IP地址时得到如下显示：

[root@server ~]# ping -c 5 59.61.250.213

在这里每一次ping外网时有显示这一行：
wrong data byte #22 should be 0x16 but was  后面的结果有的是0xca 有的是0x38 这是什么意思？
刚开始不能上网的时候我以为是DNS问题，所以检查了/etc/resolv.conf这个文件，没有问题，里面有DNS的IP地址，
后来在浏览器里直接输入IP地址也不行，解析主机的时候显示如下：

[root@server ~]# host www.163.com
;; connection timed out; no servers could be reached

ping外网域名这样显示：
[root@server ~]# ping -c 5 www.google.com
ping: unknown host www.google.com

ping网关192.168.1.1的时候也显示
wrong data byte #22 should be 0x16 but was  0x66 等信息

这是网络信息

请问我的网络配置有没有错，有的话错在哪里，谢谢
