TP-Link Archer AX12 vs Archer C80: AX1500 Wi-Fi 6 or AC1900 Wi-Fi 5?

Get the AX12 if you are buying a new router today. While the C80's AC1900 speed rating looks higher on paper than the AX12's AX1500, most devices you own in 2026 are 2x2 Wi-Fi 6 clients that will actually connect faster to the AX12 than to the C80's 3x3 Wi-Fi 5 radio, and Wi-Fi 6's OFDMA handles multiple devices more efficiently by serving them simultaneously instead of one at a time, which matters in a typical Indian home with 10-15 connected devices on a 100-200 Mbps broadband plan where the bottleneck is not raw speed but how the router manages traffic under load. The C80 still makes sense if you specifically need 4 LAN ports or have older 3x3 devices, but at nearly identical pricing in India today, buying into Wi-Fi 5 when Wi-Fi 6 costs the same is hard to justify.

Why does the C80 look faster but is not?

The C80 is rated AC1900 (1300 Mbps on 5 GHz + 600 Mbps on 2.4 GHz). The AX12 is rated AX1500 (1201 Mbps on 5 GHz + 300 Mbps on 2.4 GHz). Higher number should mean faster, right?

Not in practice. The C80 hits 1300 Mbps only when paired with a 3x3 Wi-Fi 5 client. Most phones, laptops, and tablets sold in the last three to four years are 2x2 devices. When a 2x2 device connects to the C80, its maximum drops to roughly 866 Mbps. The same 2x2 device, connected to the AX12 over Wi-Fi 6, can reach up to 1201 Mbps.

In short: unless you specifically own 3x3 Wi-Fi 5 devices (some older MacBooks, a few high-end laptops), the AX12 will be faster than the C80 for your actual devices.

What Wi-Fi 6 gives you over Wi-Fi 5?

The difference in speed classes matters less than how the two standards handle traffic.

On Wi-Fi 5, the router talks to one device at a time per channel. It is like a single billing counter at a kirana store: one customer gets served, everyone else waits. When 15 devices are connected and 5-6 are active, you feel this as micro-delays, buffering during video calls, or slight lag while gaming.

Wi-Fi 6 introduces OFDMA, which divides each channel into smaller sub-channels and serves multiple devices simultaneously. Same counter analogy, but now it has 4-5 billing windows open. For a typical Indian household in 2026 with 10-15 connected devices, this is the meaningful upgrade, not raw speed.

Where the C80 still wins?

The C80 has 4 Gigabit LAN ports versus the AX12's 3. If you hardwire a desktop, a smart TV, a NAS, and a gaming console, the C80 gives you one extra port before you need a switch. The C80's 3x3 radio also delivers stronger 2.4 GHz performance (600 Mbps vs 300 Mbps), which can help if you have older devices that only connect on 2.4 GHz.

Blacktubi's review of the C80 measured roughly 600 Mbps at short range on 5 GHz and around 400 Mbps after two walls. That is solid real-world performance for a router at this price. I could not find a comparable independent speed test of the AX12 under the same conditions, so I will not claim the AX12 is definitively faster at range. What I can say is that Wi-Fi 6's efficiency under load is well documented across the standard, not just this specific model.

Which one is for you?

If you want to buy a fresh router, get the AX12. At the same price, Wi-Fi 6 with OFDMA and EasyMesh is the better long-term investment. Your newer devices will benefit from Wi-Fi 6 immediately, and your older devices will work fine on it too since the AX12 is backward compatible with all Wi-Fi standards.

If you already have the C80,  dont rush to replace it if your network runs fine. The C80 is a solid router. But when it is time to replace, move to Wi-Fi 6 (AX12 or AX1800 class) rather than another Wi-Fi 5 model.

One note on product lifecycle: the C80 is a Wi-Fi 5 router in a market that has moved to Wi-Fi 6 and is heading toward Wi-Fi 7. TP-Link's firmware update cadence for older models tends to slow down over time. The AX12, being a current-generation product, will likely see updates for longer.
