360 T7 刷 openwrt 教程|最强的百元路由器

 https://qust.me/post/360t7-openwrt/

 

这就是 2022 年百元最强的路由器 360 T7,和红米 AX6S 相同规格的无线 Wi-Fi,同等性能的 CPU,以及同样都能刷 openwrt,但价格却只要红米的一半。360 T7 是运营商与 360 合作的定制款路由器,我买到的这款是白色的,站立式的设计比较省空间,正面有一颗 led 指示灯,背面是四个千兆的网口。

无线规格是 ax3000,支持 160Mhz 频宽的 Wi-Fi,相比红米 ax6s 的 4x4mimo 80Mhz 频宽,目前 2*2 mimo 160Mhz 还是更实用,能让近几年的安卓、Windows 设备都能达到 2400Mbps 的连接速率;CPU 是 MTK 的 MT7981,arm a53 双核 1.3GHz,和红米的 AX6s 基本相当,不过胜在 MT7981 支持的加速特性更多;以及配备了 256M 的内存 128M 的闪存。当然更多的拆解和评测可以去 acwifi 网站有非常详细的拆解评测;而我们今天的教程是把它刷成 openwrt,不能浪费这么好的配置。

教程开始前还是先感谢下:

目前的刷机教程需要拆机,用 ttl 的方式刷机,对新手不是很友好。

准备工作

1 360 T7 路由器

2 一台 Windows 电脑(需要能插网线)

3 USB 转 TTL 的模块(淘宝几块钱就能买到)

4 公对母的杜邦线(用于连接 TTL 模块和路由器)和网线

5 下载好 openwrt 固件

6 下载安装串口调试助手Termius

开启 Telnet

拆机接上 TTL

360 T7 的底部有两颗螺丝,螺丝刀捅开贴纸就能顺利拧下来。塑料后盖非常的紧,卡扣非常多,需要费点力气,当然也没法避免卡扣会掉。

拆开后,就能看到 TTL 的串口,如图里所示,从上到下分别是 RXD、TXD、GND。我们用杜邦线对应的连接好 TTL 模块即可(路由 RXD 连接模块的 TXD,TXD 连接 RXD,GND 连接 GND)。

打开串口调试助手后,串口号选择插入 COM 口设备,波特率选择到 115200,然后选择连接。

failsafe 模式下打开 telnet

现在给路由器插上电源,就能看到右边框里不断有开机日志的输出。我们不停的发送 f(记得需要回车换行,另外按 esc 能直接发送),就能看到进入 failsafe 模式。

# 开启uboot控制台菜单
fw_setenv bootmenu_delay 3

# 挂载rootfs并开启telnet
mount_root
sed -i 's/.*local debug=.*/\tlocal debug=1/' /etc/init.d/telnet

# 修改root密码为password
passwd root

password

password

# 重启
reboot

然后依次复制上面的命令到串口调试工具里执行,记得都要有回车换行符号。修改 root 密码这一步是连续两次输入相同的密码,我这里是换成了 password;最后完成 reboot 重启就可以。

输入 reboot 回车后系统就会正常重启。

刷入 uboot

重启之后我们就可以正常配置好路由器,路由器的 Wi-Fi 密码信息以及后台密码信息在 360 T7 的底部,这一步请确保路由能正常联网,因为会从网络上获取 uboot 进行刷入,当然如果你习惯 scp 或别的方式上传也是一样的。

打开 termius 选择 telnet 进行连接,默认的后台地址是 192.168.2.1,用户名是 root,密码是 password(这个是上一步自己输入修改的)。

cd /tmp
wget https://share.qust.me/d/%E8%B7%AF%E7%94%B1%E5%99%A8/360T7/360t7-fip-fixed-parts.bin
mtd write 360t7-fip-fixed-parts.bin fip

连接后复制上面的命令在 telnet 里执行,这一步会将 uboot 写入路由器。

我这执行完成后是如图的结果,现在就能开始下一步了。

uboot 刷入 openwrt

有了 uboot 刷机就非常方便了,我们先进入 uboot :路由器先顶住背面的 reset 按钮不放,再插上电源等待大约 8 秒松开 reset 就能进入 uboot。uboot 是没有 dhcp 的,用网线连接路由的 LAN 口和电脑,我们需要手动设置下电脑的 IP。

如图上电脑的 IP 手动设置为 192.168.1.2,子网掩码 255.255.255.0,网关设置 192.168.1.1,dns 也设置 192.168.1.1。

然后浏览器打开 192.168.1.1 就能进入 uboot 了,我们选择下载好的 openwrt 固件,上传刷入即可(zip 格式的需要解压)。

刷入完成路由器就会自动重启进入新的 openwrt 固件,你也能重新装好后盖正常使用。

openwrt 固件默认后台地址的是 192.168.6.1,用户名是 root,密码 password,默认的 Wi-Fi 名是 mtk 开头的,默认 Wi-Fi 没有密码。

openwrt 性能测试

首先 coremark 跑分 8803.7,MT7981 还行能看,都是 arm a53 主频和核心数肯定直接影响得分,这个双核 1.3Ghz 也就差不多这水平了。

科学性能能跑到 800Mbps 左右,这里需要说一下用的是 passwall,ss 的加密是 chacha20-ietf-poly1305,我手动选择了 rust 的版本,如果默认的 Libev 版本大约只有 300Mbps 左右。

hwnat 硬件加速工作正常,跑满 1000M 宽带 CPU 基本没有占用。

无线信号真的非常不错,近处用 iPhone 13 测试无论原厂还是 openwrt 都能有 700Mbps 以上。

隔了一堵区墙后也能有 450Mbps 以上,效果比之前的 ax6s 还略好一点。

总结

360 T7 一百多的价格,搭载了 MTK MT7981,无论是无线 Wi-Fi 性能还是刷机后的科学性能都非常非常有性价比了,也有 uboot 刷机方便不用担心刷挂了;目前唯一的缺点就是刷机需要拆机用 ttl,有点麻烦对新手不友好。

Interview at the All Things Digital D5 Conference, Steve and Bill Gates spoke with journalists Kara Swisher and Walt Mossberg onstage in May 2007.

Kara Swisher: The first question I was interested in asking is what you think each has contributed to the computer and technology industry— starting with you, Steve, for Bill, and vice versa. Steve Jobs: Well, Bill built the first software company in the industry. And I think he built the first software company before anybody really in our industry knew what a software company was, except for these guys. And that was huge. That was really huge. And the business model that they ended up pursuing turned out to be the one that worked really well for the industry. I think the biggest thing was, Bill was really focused on software before almost anybody else had a clue that it was really the software that— KS: Was important? SJ: That’s what I see.

巴菲特致股东信-1976年

 笔记: 为什么选择轻资产行业:当竞争疯狂时,不会强迫加入降价大战 最终选择了费雪的思想,选择能理解的优秀企业,以合理的价格买入并长期拥有 翻译: 雪球:https://xueqiu.com/6217262310/131440258 备份:https://archive.ph/XLK0S 原文: To the Stockholders of Berkshire Hathaway Inc, After two dismal years, operating results in 1976 improved significantly. Last year we said the degree of progress in insurance underwriting would determine whether our gain in earnings would be "moderate" or "major." As it turned out, earnings exceeded even the high end of our expectations. In large part, this was due to the outstanding efforts of Phil Liesche's managerial group at National Indemnity Company. In dollar terms, operating earnings came to $16,073,000, or $16.47 per share. While this is a record figure, we consider return on shareholders' equity to be a much more significant yardstick of economic performance. Here our result was 17.3%, moderately above our long-term average and even further above the average o...

Commencement Address at Stanford University--“Stay hungry. Stay foolish.”

I am honored to be with you today for your commencement from one of the finest universities in the world. Truth be told— I never graduated from college. This is the closest I’ve ever gotten to a college graduation. Today I want to tell you three stories from my life. That’s it. No big deal. Just three stories. The first story is about connecting the dots. I dropped out of Reed College after the first six months but then stayed around as a drop-in for another eighteen months or so before I really quit. So why did I drop out? It started before I was born. My biological mother was a young, unwed graduate student, and she decided to put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife. Except that when I popped out they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting...

巴菲特致股东信-1975年

Our operating earnings for 1975 were $6,713,592, or $6.85 per share, producing a return on beginning shareholders ’ equity of 7.6%. This is the lowest return on equity experienced since 1967. Furthermore, as explained later in this letter, a large segment of these earnings resulted from Federal income tax refunds which will not be available to assist performance in 1976. On balance, however, current trends indicate a somewhat brighter 1976. Operations and prospects will be discussed in greater detail below, under specific industry titles. Our expectation is that significantly better results in textiles, earnings added from recent acquisitio...

巴菲特致股东信-1973年

 笔记: 在上一年度预测的今年竞争加剧导致利润下滑,真的发生了 翻译Link: 雪球:https://xueqiu.com/6217262310/131257618 备份:https://archive.ph/KIfdT 原文: To the Stockholders of Berkshire Hathaway Inc.: Our financial results for 1973 were satisfactory, with operating earnings of $11,930,592, producing a return of 17.4% on beginning stockholders' equity. Although operating earnings improved from $11.43 to $12.18 per share, earnings on equity decreased from the 19.8% of 1972. This decline occurred because the gain in earnings was not commensurate with the increase in shareholders' investment. We had forecast in last year's report that such a decline was likely. Unfortunately, our forecast proved to be correct. Our textile, banking, and most insurance operations had good years, but certain segments of the insurance business turned in poor results. Overall, our insurance business continues to be a most attractive area in which to employ capital. Management'...

Steve Jobs introduced the iPhone on January 9, 2007.

This is a day I’ve been looking forward to for two and a half years. Link Every once in a while, a revolutionary product comes along that changes everything. And Apple has been— well, first of all, one’s very fortunate if you get to work on just one of these in your career. Apple’s been very fortunate. It’s been able to introduce a few of these into the world. In 1984, we introduced the Macintosh. It didn’t just change Apple, it changed the whole computer industry. In 2001, we introduced the first iPod, and it didn’t just change the way we all listen to music, it changed the entire music industry. Well, today, we’re introducing three revolutionary products of this class. The first one is a widescreen iPod with touch controls. The second is a revolutionary mobile phone. And the third is a breakthrough internet communications device. So, three things: a widescreen iPod with touch controls; a revolutionary mobile phone; and a breakthrough internet communicat...
