Wi-Fi technology continues to evolve rapidly. The transition from 802.11n to 802.11ac is widespread, with 802.11ad and 802.11ax on the horizon for even faster speeds and better bandwidth management. Today, 802.11ac routers remain the gold standard, but not all are equal in performance.
Router models often feature ratings like AC1200, AC1900, or AC5300, suggesting theoretical maximum speeds in Mbps. In reality, treat these 'theoretical maximums' with caution—they rarely reflect everyday use.
These AC ratings, such as AC1200 or AC1900, indicate total bandwidth across the router's frequency bands, regardless of brand.
The figure sums the maximum throughput of each band, typically 2.4 GHz and 5 GHz. For example, a router might deliver 450 Mbps on 2.4 GHz and 1300 Mbps on 5 GHz, totaling 1750 Mbps for an AC1750 model. Higher ratings come from faster bands (like 1733 Mbps) or additional bands.
Key limitation: Devices connect to one band at a time. A device on the 1300 Mbps 5 GHz band can't access the 450 Mbps 2.4 GHz band simultaneously, leaving extra capacity unused. More bands boost multi-device handling, not single-device speed.
Even on a single band, advertised speeds like 1300 Mbps are lab-tested under perfect conditions: premium hardware, single-device connections, short distances, and optimized software.
In real homes, expect far less. Even ideally, surpassing 70% of rated speed—around 600-700 Mbps—is rare. A solid AC1200 router typically delivers 300-400 Mbps in optimal scenarios, with premium models offering only modest gains.
Higher AC ratings signal more antennas, bands, and advanced features like MU-MIMO, which maintains speeds for multiple users streaming or gaming simultaneously.
An AC5300 with four antennas can support four high-bandwidth users without throttling, unlike basic models. Higher per-band speeds also handle multi-device loads better. For light use, an entry-level AC router suffices.
AC ratings are sums of unattainable band maximums, best indicating multi-device capacity rather than single-connection speed.
For true performance insights, consult expert reviews and real-world benchmarks. Gigabit Wi-Fi is emerging, but most connections top out below 500 Mbps—Ethernet remains reliable for wired needs.
