使用 Broadcom 4352 无线网卡时出现问题

使用 Broadcom 4352 无线网卡时出现问题

不确定这是否重复Broadcom STA 驱动程序与 BCM4313 配合不佳或者不是。我认为是同一系列,但我没有看到对 4352 或 43xx 的明确引用(暗示它适用于所有 43xx 系列)。

Canonical 声称支持该卡在这里当我启动实时安装 CD 时,在启用驱动程序后,它就可以正常工作了software-properties。坦白说,我没有充分使用它来查看连接是否不稳定。相反,我启动了服务器安装 USB,现在我正尝试在安装后对其进行配置。

我当前的程序是运行这个脚本,它是根据我在不同地方读到的片段构建的。

CONFFILE=/etc/wpa_supplicant.conf
CONF=$(cat <<CONFEND
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wireless
update_config=1

ENDCONF
)

echo "$CONF" | sudo tee $CONFFILE > /dev/null
wpa_passphrase "" "" | sudo tee -a $CONFFILE > /dev/null

sudo kill-all wpa_supplicant
sudo wpa_supplicant -B -Dwext -ieth0 -c$CONFFILE
sudo dhclient eth0

现在,有时它会在大约 15 秒内运行,发出两个错误(ioctl[SIOCSIWENCODEEXT]: Invalid argument),但运行正常。无法判断连接是否不稳定,或者我在中选择了一个较差的镜像apt。但是其他时候,它需要 5 分钟以上的时间才能运行,并且在我终止它之前没有发出任何有用的信息。我尝试单独运行wpa_supplicantdhclient行,每行都需要很长时间并且没有报告任何有用的错误。这些情况下的最终结果是iwconfig显示接口已关联,但ifconfig没有显示 ipv4 地址并dhclient拒绝获取一个。

以下是一些调试信息:

编辑:添加了额外的诊断信息

答案1

我建议对 /etc/network/interfaces 进行更简单的安排。我还建议,为了能够通过 ssh 和 ftp 进入服务器,请使用静态 IP 地址。如果在新的命名方案下,“em1”是您的以太网,则您要求以太网和无线都自动启动。我会将 /etc/network/interfaces 更改为:

auto lo
iface lo inet loopback

#auto em1
iface em1 inet dhcp

auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
gateway 192.168.1.1
wpa-ssid <your_router>
wpa-psk <your_secret_key>
dns-nameservers 8.8.8.8 192.168.1.1

当然,在路由器中选择一个 DHCP 池之外的地址并替换您的详细信息。让系统读取并使用这些更改:

sudo ifdown eth0 && sudo ifup eth0

可能需要重新启动。

如果您的 cfg80211 警告仍然存在,我建议我们在无线顺利连接后排除故障。
