1997 musste er seine Prognose, dass das Internet kollabieren würde, im wörtlichen Sinne aufessen. Das hat ihm offensichtlich nicht allzu sehr geschadet. 😜

Recommendations on a 24port 2.5 and 10Gbs switch for a home network?

I would like to swap out my aged 1Gbs managed switch with an unmanaged variety. (I used VLANs at the start but long ago decided they were more work than they were worth for even a relatively complex/busy home network)

currently trolling ebay.

Oh, also if you have recommendations for places to obtain such a beast with decent shipping to Canada, let me know!

If that laptop doesn't have an RJ-45 [1] socket on it, it's not a business/enterprise unit. [2] Full stop.

[1] Yes, technically 8P8C modular connector, but nobody calls it that.

[2] That makes it a consumer-grade machine, and should be treated as having an expiry date as long as its 1-year warranty. Every day after that is a gift.

Ethernet cables come in CAT categories, each one defines bandwidth, speed, and how far you can push data before signal quality drops 😎👇

Rockchip RK3506J-based Forlinx FCU1501 fanless industrial IoT gateway offers dual Ethernet, plenty of I/Os and serial interfaces

Forlinx Technology has recently introduced the FCU1501, a rugged, fanless industrial embedded computer and IoT gateway built around the Rockchip RK3506J processor with a tri-core Cortex-A7 and a single Cortex-M0 core. The system is designed for high-reliability data acquisition and protocol conversion in harsh environments. The gateway comes in two variants (basic and extended), which have similar dimensions but differ mainly in interface density. Both models feature up to 512MB DDR3 RAM, 8GB eMMC flash, dual Fast Ethernet, dual-band Wi-Fi & Bluetooth 5.0, and 4G LTE Cat 1 support. Applications include automation, rail transit, and smart manufacturing. The system supports a wide industrial temperature range (-40°C to +85°C) and meets Level 3 EMC standards. Forlinx FCU1501 Specifications: SoC – Rockchip RK3506J CPU 3x Arm Cortex-A7 cores up to 1.5 GHz Arm Cortex-M0 real-time core GPU – 2D GPU only No VPU, no NPU System Memory – 256MB or 512MB DDR3 Storage 256MB NAND
