Re: 求教大神BCM43340网卡在Ubuntu16.04下无法驱动的问题

这台平板二合一没有有线网卡,无法更新…poloshiao 写了:目前 Ubuntu 16.04 應該是 4.4.0.47-generic 核心3内核是 4.4.0-21-generic
你更新看看
sudo apt update
sudo apt upgrade
sudo systemctl reboot

而根据brcmfmac文档 https://wireless.wiki.kernel.org/en/use ... /brcm80211 ,BCM43241 和BCM43340属于同一类sdio设备,目前看来是无解了。
1. 該網頁 只說明 BCM43241 和 BCM43340 都是受到 brcmfmac 支援 的 sdio 设备https://wireless.wiki.kernel.org/en/use ... /brcm80211
Supported Chips
brcmfmac
SDIO devices
BCM43340 0xa94c Supported in 4.0+
BCM43241 0x4324 Supported in 3.7+
3. 上面只是說 無法使用 lspci 或 lsusb 偵測到 BCM43241 並沒有說 無法安裝 驅動跟固件https://wiki.archlinux.org/index.php/Broadcom_wireless
根据上面资料显示:
Device BCM43241 non-detected
This device will not display with either lspci nor lsusb; there is no known solution yet. Please remove this section when resolved.

这篇帖子的第三页最后一条提到poloshiao 写了: 5. 這一篇 還有許多豐富的討論內容

我觉得这才是问题的关键所在,系统根本没有识别这个设备,我也看了我这/sys/bus/sdio/devices/目录下确实是空的。@BBaker: I installed the BCM43430 firmware in /lib/firmware/brcm/ and loaded brcmfmac module but nothing happend. Since it’s a SDIO device, it uses the SD card interface so I think we have to get the SD card reader working first. According to this [thread](https://github.com/hadess/rtl8723bs/issues/20), you have to probe SDIO devices using /sys/bus/sdio/devices/ (not lspci) and if there is nothing there, then the OS cannot see the SDIO device. There is nothing in that directory for me.
2. 有沒有 USB 插口 ?这台平板二合一
感谢poloshiao大神最近几天的回复,先结贴吧,过几个月再看,用这台平板二合一设备装ubuntu纯属娱乐,暂时解决不了没关系的,可以装双系统。poloshiao 写了:1. 看完最後一個帖子
