Chip was primarily designed to allow #robots to work in contaminated areas for decommissioning #nuclear reactors. Regular silicon #semiconductors used for wireless communication are susceptible to interference from nuclear radiation, meaning robots are limited by physical cable needed to control them https://www.tomshardware.com/networking/routers/researchers-build-wi-fi-chip-that-can-operate-inside-a-nuclear-reactor-receiver-uses-special-materials-and-design-to-withstand-high-doses-of-radiation-for-at-least-six-months

Today, I picked up a GL.iNet Flint 3 router (model GL-BE9300). 🛜

I honestly wasn’t planning to buy a new router right now. Even though my TP-Link Archer AX6000 (Wi-Fi 6) was discontinued a few months ago, my plan was to hold out until Wi-Fi 8 next year.

And then… Donald Trump happened. 🤬

More specifically, the Trump regime ordered the FCC to outlaw routers not made in the USA — and as far as I know, there are currently no consumer routers manufactured in the U.S. 🇺🇸 That could mean a serious supply crunch is coming. I’ve also seen reports suggesting future U.S.-made routers may be required to include a “control chip” and FCC-approved firmware. 😡

That raises some real privacy concerns ⚠️ Because historically, regimes with strong centralized control tend to prioritize monitoring and restricting their citizens.

That said, the Flint 3 is an absolute beast 💪
It’s a tri-band (2.4 / 5 / 6 GHz) Wi-Fi 7 router with:

1× 2.5 Gbps WAN port
3× 2.5 Gbps LAN Ethernet ports
1× 2.5 Gbps WAN/LAN combo port (usable as either)
And it runs open-source firmware (OpenWrt) 🔓

In other words, this is about as high-end and flexible as it gets right now.

GL.iNet is based in Hong Kong, and the router is manufactured in China — which, to be fair, is where most routers have been made for the past decade or more (Linksys, Netgear, TP-Link, etc.). 🌍

All things considered, I do suspect we could see supply issues down the line… so this felt like a smart move. Especially to get ahead of any built-in spyware or potential hardware backdoors — thanks to “Uncle Sam” (U.S. Government).

does anyone knows what's the root cause of this issue/bug ? I've had the exact same problems and I suspect it's because of my wi-fi card drivers / 6.4 kernels and onwards

basically: frequent wifi disconnects, complete unrecoverable system crashes during high network activity, and no sysrq responses afterwards. logs say nothing
