We used a "dual-band" router for a decade as an internet gateway and an AP. Turned out it can transmit either in 2.4GHz OR in 5GHz range, but not both. When I switched it to 5GHz, no device was able to see it. Except a half-dead flagship Lumia 1520 from several years ago. <a href="None://fireburn.ru/tags/networking" class="u-category">#networking</a> <a href="None://fireburn.ru/tags/weird" class="u-category">#weird</a>
