<p data-start="86" data-end="323">I still remember the day our office network started slowing down right before a big client demo. Streaming lagged, file transfers crawled, and everyone blamed the router. That&rsquo;s when I first heard about upgrading with expansion hardware.

<p data-start="325" data-end="657">A colleague suggested trying TP-Link expansion modules, saying they could improve scalability without replacing the entire setup. I was skeptical at first, thinking it was just another marketing promise. But after testing them in a small gigabit network, the difference was noticeable, especially in stability during peak hours.



<p data-start="659" data-end="863" data-is-last-node="" data-is-only-node="">Still, I keep wondering if they truly justify the investment for larger networks or if a full switch upgrade is the smarter long term move. Has anyone here made the switch and seen real performance gains?
