新安的GENTOO上不了网。

houjianyu84

把broadcom的网卡安好了，连接没问题。DHCPCD得到IP，ping自己没问题。极偶尔在重启后得到新IP能连上校园网主页，可不到一分钟就再也连不上了。被折磨多日。新安好的系统连net-setup都找不到。我用的是2008beta2。 PS:为了打中文，用手机跑到校内上发日志，再贴到贵处。因为我不会在liveCD上打中文。最于发了个中文贴。让各位大虾看个明白。

好复杂啊，上不了网有很多情况，还有你的网络环境也得说明白啊，大家怎么会知道你是怎么连上internet的？

对啊，至少先来个:
ifconfig -a
lspci
dmesg
等等

夕角

对了，我用学校的 dns ，上网经常不正常的，也许你也该改改 dns 试试:

2. $ cat /etc/resolv.conf
3. nameserver 208.67.220.220
4. nameserver 208.67.222.222

要在 dhcpcd 后改

This is my /etc/conf.d/net

DNS写在 /etc/resolv.conf 里没用，重启后自动被/etc/conf.d/net覆盖

可是覆盖之后还是这两个DNS啊。而且这两个DNS本来就ping不通。哎呀，我真不知道该怎么办了。现在正在重装系统。因为编译时很多文件在教育网内不能安，又暂时找不到合适的代理，只好在家重安。
