无法连接到 g/n wifi 网络 - 我的驱动程序有问题吗?

无法连接到 g/n wifi 网络 - 我的驱动程序有问题吗?

我正在使用戴尔 XPS 13。

我的笔记本电脑禁用了对 b 范围 wifi 的支持并开始专门使用 g/n 范围 wifi 后,无法连接到 wifi 网络。这让我怀疑我的笔记本电脑无法连接到仅使用 g/n wifi 范围的 wifi 网络。

如何使我的笔记本电脑连接到 g/n 范围的 wifi 网络?

摘自这两篇文章:

无法在 Ubuntu 上连接混合 b/g/n wifi 网络

无法连接到 WiFi Broadcom Corporation BCM4313 802.11b/g/n 无线局域网控制器 (rev 01)

我怀疑我需要更新我的 wifi 驱动程序。我应该这样做吗?如果是,怎么做?

以下是输出sudo lshw -C network

我有相同的 Wifi 卡:

*-network
   description: Wireless interface
   product: QCA6174 802.11ac Wireless Network Adapter
   vendor: Qualcomm Atheros
   physical id: 0
   bus info: pci@0000:3c:00.0
   logical name: wlp60s0
   version: 32
   serial: 9c:b6:d0:10:37:f7
   width: 64 bits
   clock: 33MHz
   capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
   configuration: broadcast=yes driver=ath10k_pci driverversion=4.14.78-041478-generic firmware=WLAN.RM.4.4.1-00079-QCARMSWPZ-1 ip=192.168.1.68 latency=0 link=yes multicast=yes wireless=IEEE 802.11
   resources: irq:138 memory:dd200000-dd3fffff

它使用相同的驱动程序,但是针对较旧的内核进行编译:

driver=ath10k_pci driverversion=4.14.78-041478-generic firmware=WLAN.RM.4.4.1-00079-QCARMSWPZ-1

您的固件也相同:

firmware=WLAN.RM.4.4.1-00079-QCARMSWPZ-1

回答您的问题,据我所知,没有较新的驱动程序可供您使用。

但是您可以使用此命令来检查错误:

$ lspci -nnk | grep -iA2 net; dmesg | grep ath10k
