我的 PC 上有一根以太网电缆，还有一个 USB 无线适配器。我想创建一个使用有线连接互联网的 WiFi 网络。
因此，我添加了一个新的无线网络，但是现在它连接后立即断开连接 - 我看到“建立连接”然后“断开连接”等等（我已将其设置为自动连接）。
我的适配器是Bus 002 Device 002: ID 0bda:8187 Realtek Semiconductor Corp. [RTL8187][1] Wireless Adapter。链接的页面包含一些说明，但我无法下载 Win98 驱动程序。这是我解决问题所需要的吗？
此外，还有一些有趣的系统日志条目：

尝试这个解决方案：
我也遇到了类似的问题。
为了解决这个问题，我在 /etc/modprobe.d/blacklist.conf 的底部添加了以下三行
blacklist bcma
blacklist brcmsmac
blacklist brcmutil
