OpenWrt Hits Dual 1GbE, Console Failures on Intel D2500CC as Author Weighs $100 ARM Alternatives

An Intel D2500CC board finally booted the same OpenWrt SD card that failed on earlier hardware, but its dual 1GbE ports showed no link activity and the console soon began corrupting.
The board did detect both onboard NICs as eth0 and eth1, leaving the failure unclear—possibly bad hardware, a BIOS quirk, the OpenWrt image, or another USB-related issue.
That setback came after the author revisited DIY router choices for 2026, arguing that at least 1GbE networking is now the practical minimum even for a 300 Mbps fiber plan.
On ARM hardware, older Raspberry Pi-class SBCs are constrained by USB 2.0 to roughly 300 Mbps, while dedicated OpenWrt boards such as OpenWrt One and Banana Pi BPI-R4 start around $100 bare.
The next step is basic hardware validation before more OpenWrt testing; one earlier Intel board already looked suspect after Memtest86+ crashed immediately, and OPNSense remains a fallback for the D2500CC systems.
When even dedicated OpenWrt hardware can brick, are versatile ARM boards like the Raspberry Pi the superior DIY choice?
As internet speeds surpass 2.5Gbps, is the era of high-performance DIY routers built from salvaged parts now over?
Is a DIY router from old parts a cost-saving hack, or an expensive hobby with no guarantee of success?
