A Closer Look at the Design: Both Internal and External
The Good and the Bad!
The overall external design is impressive; however, there are a few issues to address. For instance, incorporating a small wide cut in the rear cover would facilitate the passage of extra cables, particularly for users who wish to connect a microcontroller or sensor to the mikroBUS socket.
Having three LAN ports offers greater advantages than having only two!
For some unknown reason, OpenWrt team missed an opportunity to enhance the rear panel of the case by adding an extra square cutout with screw holes for a third 2.5GbE LAN port. It’s important to note that in this type of configuration the M.2 socket would be utilized for the LAN controller expansion card, preventing the addition of an NVMe SSD. However, if NVMe support isn’t a priority for you, a high-quality Micro SD card can be a viable alternative.
The M.2 B/M Key 2.5Gb Ethernet Card is equipped with an Intel I225 chipset for its RJ45 LAN Controller and boasts compatibility with the OpenWrt kernel. Should you decide to undertake this installation, proceed cautiously. Additionally, achieving the appropriate fit for the Ethernet port will require precise cutting, which can be achieved through milling, water cutting, or a punch machine.
The opening on the right is designed to accommodate a flat cable and other wiring, enabling them to exit the case smoothly. The photo below shows the redesigned back cover case, which includes marked sections in red indicating areas to be cut.

It’s a mistake to compare the router with BPI R4.
Compare it with BPI R3. Unfortunately Openwrt One looses in every possible category including price.
OpenWrt may have prioritized profit over customer value, which could be considered a strategic mistake.
no, check out the latest news of TP-Link. This Chinese company has been selling these insecure routers, sometimes at costs lower than what it takes to manufacture. This is truly an alarming issue, certainly consumers in the US have been given unrealistic prices for decent router hardware, and much of our internet infrastructure is based on highly insecure hardware. If you have a TP-Link router, try breaking in with password “1234” it’s scary how simple it can be!
You can always consider purchasing an Asus router may come at a higher price point, it generally offers enhanced security. It’s important to note that the lower price of open-source-based routers is not necessarily a cause for concern. These routers tend to be more affordable due to their DIY nature, which often means less direct customer support and software.
I believe the OpenWrt community offers significant advantages over manufacturer firmware. However, the lack of a standardized method for evaluating the security of routers remains a concern. Same goes with electric cars and other products.

Thanks. It should be fine now.
Please check..
Working again – thx!
I got myself one and sadly I must say the wireless range and connection stability is way worse than a Cudy WR3000 that uses the same SoC and comes at 1/3 of the price. So I had to pull back.
I didn’t notice any difference in connection range or stability problems when I compared performance to one of my stronger Chinese routers.
Again, it depends if you have a lot of walls that might interfere with signal reception. You can check the latest update, maybe there are improvements or tweaks in newer OpenWrt releases.
You can also buy WiFi signal boosters on AliExpress and check if it helps.
