Towards the close of last year, news emerged that the US government had initiated an investigation into the prominent router brand TP-Link, with the potential to ban the sale of its products. TP-Link enjoys widespread popularity among users due to its exceptional cost-performance ratio, with prices typically 50% lower than those of its competitors. The brand holds a significant share of approximately 65% in the US market for household and small business routers, and it is also the standard equipment provided by numerous Internet service providers for new subscribers.
