2026 has been a trying year for router manufacturers, as the Federal Communications Commission (FCC) has subjected leading companies to strict oversight and outright bans. As an olive branch of sorts, the FCC has handed out "conditional approvals" to be included on the Covered List to companies that have jumped through all the necessary hoops to satisfy the commission's concerns. Asus is the latest company to secure that approval, which was confirmed in an FCC notice issued this week.

According to the FCC, the following Asus networking products have been granted conditional approval:

• RT Series
• ROG GT Series
• OG Strix GS Series
• TUF Gaming Series
• ExpertWiFi Series
• ZenWiFi Mesh Series
• 5G MiFi Series
• Wireless repeaters
• Wireless access points

In other words, Asus' entire wireless networking portfolio is cleared for sale in the U.S., with the conditional approval granted until March 6, 2028 (18 months from the date of issuance). The FCC explains, "We find that each of the Conditional Approvals constitutes 'a specific determination' by [Department of War] that such devices do not pose risks to U.S. national security."

This latest move by the FCC is a welcome sigh of relief for Asus, a Taiwanese company with an extensive networking portfolio and some of the best Wi-Fi routers. More importantly, Asus is ready to unleash a whole new generation of Wi-Fi 8 products over the next year. Wi-Fi 8 promises significant reliability and quality-of-life improvements across a wide range of wireless devices, so having a front-row seat to the transition from Wi-Fi 7 to Wi-Fi 8 is pivotal for Asus.

We've already seen a concept ROG NeoCore Wi-Fi 8 router from Asus at CES this year, and the company announced its first consumer Wi-Fi 8 router, the ROG Rapture GT-BN98 Pro, in June. The ROG Rapture GT-BN98 Pro is promising a 2x uplift in real-world throughput compared to its current-generation Wi-Fi 7 products.

Asus joins Netgear and Amazon Eero/Leo on the conditional approval list. The largest player in the U.S. wireless router market is TP-Link, and it still hasn't gained FCC approval. The U.S. government's reluctance to approve TP-Link stems from uncertainty about its claims that it has no ties to the Chinese government or military. As a result, the company has not confirmed a release date for its newly announced Wi-Fi 8 "Ultra" routers in the U.S.

The Greenlink Connector, which costs $580 million (GBP 430 million) and connects Ireland to Wales via an undersea power cable, was rerouted after scores of Harry Potter fans complained that it would go through the grave of the beloved house elf “Dobby.” According to The Guardian, project manager Simon Ludlam pointed out in a BBC interview that the cable would transition underwater at Freshwater West. Unfortunately, Ludlam was unaware that this was the filming location for the site where the Harry Potter character was buried in the movie franchise. When the BBC aired the clip, the project began receiving hundreds of calls about the site.

Ludlam recounted to The Guardian a discussion with a colleague when they told him, “Apparently, we’re going to go straight through Dobby’s grave.” He answered, “Dobby? Who’s Dobby? I don’t know Dobby.” It seemed that the project manager was in disbelief when it was finally explained that Dobby is the freed house elf who was killed in the process of rescuing Harry Potter and his friends in the last book. “He is a fictitious character in a fictitious book — the whole thing is fictitious. What are you talking about?” Ludlam said, after which his colleague replied, “No, it’s very, very serious.” In the end, the company working on the project acquiesced to the demands and concerns of the Harry Potter fans and rerouted it. “A lot of people were very happy about that, and the project is now going [ahead], and Dobby’s happy,” the project manager said.

The Shell Cottage, where Dobby is buried, is on the outskirts of the fictional town of Tinworth, in Cornwall, but the original film series shot the scene in Freshwater West. Many Harry Potter fans leave stones marked with “Here lies Dobby, a free elf,” as a nod to the epitaph that the titular hero left on his grave. The National Trust, which owns the land, has previously warned pilgrims not to do so, as the area is ecologically sensitive, but it seems that people still do so. The fans’ resistance to having Dobby’s “grave” desecrated seemingly prevented the undersea cable from going through the area. It was instead rerouted in an area that was close to some Bronze Age remains and urns, which, ironically, are associated with human burial.

Undersea cables are crucial infrastructure connecting distant locations for sending information, power, and other crucial resources. Many of them face increasing threats, especially in areas that face geopolitical pressure, like Taiwan and the Baltic Sea, which is why companies are creating technologies to help detect intentional tampering. However, it seems that the one thing that the planners of this particular project did not take into account is the passion of Harry Potter fans.

A developer has created a proof-of-concept data transfer system that shuns any dedicated app requirement and neatly sidesteps mandatory networking, pairing, or giving permissions beyond camera access. Instead, the method transmits information between devices by streaming data via rapidly updating QR codes at up to 60 FPS via the browser your smartphone already has. The test info shared by developer bashalarmistalt on GitHub backs claims that these transfers can run at up to 190 KB/s. This low-friction two-device screen-to-camera data transmission technique is dubbed Decimen Optical Transfer: fountain-coded QR file transfer.

Had an idea for air gapped file transfer, able to get 120 KB/s from r/vibecoding

The GitHub project is linked to by Redditor Alstroph, who seems to be the same person. We’ve chosen to embed the Reddit post about the Decimen Optical Transfer solution above, as it includes an illustrative video of a QR code-driven data transfer.

Bashalarmistalt/Alstroph says they used Claude Code to build this cached web app, which simply runs on both smartphones within the browser, with camera permissions given. They explain that they came up with the idea behind Decimen Optical Transfer to create “a phone-to-phone file transfer option without requiring the phones to be on the same network.” After a modicum of chin stroking, they settled upon the possibility of using “rapidly flashing QR codes” to brew up this proof-of-concept.

Far more detailed information about the project is available in the GitHub repository, linked above. There we also read that the use of ‘fountain codes’ was instrumental to the technique, ensuring missed frames and retransmission quirks don’t hinder the data transfer process. Also, it is explained that every streamed QR code frame is self-describing, as a “20-byte header carries the session ID, sequence number, block count/size, file length, and a hash.”

Hints are provided for tuning Decimen Optical Transfer performance with the PoC solution. The dev used an iPhone and the Apple ProMotion camera with stacked codes; they achieved ~128 KB/s handheld data transfers. The data rate could climb to ~186 KB/s speeds if both the sender and receiver devices were positioned absolutely stationary.

The Decimen Optical Transfer software is distributed under the generous MIT license. Bashalarmistalt is aware that there have been several prior projects but asserts the concept behind their Claude Code-aided solution was arrived at independently. We’ve also covered QR code-based data storage tech numerous times. For example, Cerabyte famously uses microscopic QR codes for its ultra-long-life ceramic storage.
