上网不稳定以至于上不了网(有traceroute测试,请高手帮忙分析)

不知道哪里出了问题,希望高手帮忙分析,给出解决方案

网络情况:
从团委那里的交换机处连接一台100Mbps交换机到楼长处,从楼长处接一10Mbps集线器到我宿舍,网线长22m
宿舍两台电脑,一直都可以上网,但是上网也存在问题的,下载速度是很快的,都是上M级别的,但是打开网页一直都不怎么快
今天上网不稳定,打开网页奇慢,后来干脆就挂了,qq,fetion也登录不上,ping网关也只是偶尔能ping通。。。
(补充:qq可以登陆上了,但是发个消息都超级慢,迅雷还可以继续下载,此情况在windows下和linux下都是一样的)
