Linksys E8450 OpenWRT 配置 w/ 802.11ax

背景

之前用的 newifi 路由器(Lenovo y1s)无线网总是出问题,于是换了一个新的支持 802.11ax 的路由器 Linksys E8450,目前在 openwrt snapshot 支持。Openwrt 的支持页面:Linksys E8450

过程

按照支持页面,下载固件:

$ wget https://downloads.openwrt.org/snapshots/targets/mediatek/mt7622/openwrt-mediatek-mt7622-linksys_e8450-squashfs-sysupgrade.bin

然后访问固件升级页面:http://192.168.1.1/config-admin-firmware.html#firmware,选择下载的 bin 文件。点击 “开始升级”,然后等待。一段时间后,ssh 到路由器:

$ ssh root@192.168.1.1
The authenticity of host '192.168.1.1 (192.168.1.1)' can't be established.
ED25519 key fingerprint is SHA256:REDACTED.
No matching host key fingerprint found in DNS.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added '192.168.1.1' (ED25519) to the list of known hosts.

配置 luci:

$ opkg update
$ opkg install luci

然后就可以网页访问看到 luci 了:Powered by LuCI Master (git-21.060.51374-cd06e70) / OpenWrt SNAPSHOT r16242-41af8735d4。

由于目前 luci 不支持 802.11ax 的配置,可以直接修改 uci 配置来达到效果:

root@OpenWrt:/# uci show wireless
root@OpenWrt:/# uci set wireless.radio1.htmode='HE80'
root@OpenWrt:/# /etc/init.d/network restart
'radio0' is disabled

注:实际上设置为 HE 开头的字符串即可,见 mac80211.sh

再连接上 Wi-Fi 的时候就可以看到是 802.11ax 模式了。也在 OpenWRT 论坛 上分享了一下这个方案。
