RAX54v2 Locked to Canada

Is this a new purchase? 

What firmware version is on it?

I live in a area with high interference and was doing latency sensitive task so decided to use 160MHz and DFS.

Not sure this is a smart choice, especially considering we don't face a Wi-Fi 7 system supporting  notching (formally known as preamble puncturing) is a feature that keeps your network stable when another signal or device interferes with part of your Wi-Fi channel. Instead of dropping the whole channel to a slower speed, the router simply "notches out" or skips the dead spot and uses the remaining clean bandwidth

 

I see what you were trying to do there—chasing that maximum throughput to crush latency—but you might have accidentally set yourself up for a bumpy ride.

 

In a high-interference environment, switching to 160 MHz and DFS (Dynamic Frequency Selection) is actually a bit like trying to drive a wide-load semi-truck through a crowded city centre to get somewhere faster. It sounds powerful on paper, but reality has a way of slowing you down.

Here is why that combination is likely hurting your latency, and what you should do instead.

The 160 MHz Problem: More Channel, More Problems

To get a 160 MHz channel, your router has to bind a massive chunk of the wireless spectrum together.

• The Noise Magnet: A wider channel acts like a wider net. It catches more data, but it also catches vastly more background noise and interference. In a high-interference area, this drops your Signal-to-Noise Ratio (SNR).
• Packet Loss & Retries: When interference hits any part of that 160 MHz band, data gets corrupted. Your devices then have to re-transmit those packets. In latency-sensitive tasks (like gaming or video calls), re-transmissions = lag spikes.

The DFS Problem: The Sudden Eviction

DFS channels share space with military, weather, and airport radar systems. By law, routers must yield to these radars.

• The Radar Silent Treatment: If your router detects even a whisper of a radar signal, it must instantly drop the channel.
• The 1-to-10 Minute Blackout: Your router then has to move to a new channel and scan it for 1 to 10 minutes before letting your devices reconnect. If you are mid-match or mid-meeting, you will completely drop connection.

The Counter-Intuitive Fix for Low Latency

If low, stable latency is your ultimate goal in a crowded area, narrower and quieter is always better than wider and louder. Try these adjustments:

1. Drop down to 40 MHz or 80 MHz

• Why: You cut the interference net in half (or quarters). Your connection becomes dramatically more robust against ambient noise, resulting in fewer dropped packets and fewer sudden ping spikes. You still get plenty of speed for any latency-sensitive task.

2. Ditch DFS for Non-DFS Channels

• Why: Stick to the standard UNII-1 (Channels 36–48) or UNII-3 (Channels 149–161) bands for the US/Canada/Australia (not for ETSI regulatory, where these channels are reserved for SRD). They don't require radar monitoring, meaning your router will never abruptly clear the channel and leave you hanging.

3. The Ultimate Latency Cure: Ethernet or 6 GHz

• Ethernet: If it is at all physically possible, run a Cat6 cable. It completely bypasses the airwave traffic jam.
• Wi-Fi 6E / Wi-Fi 7 (6 GHz): If you have newer devices that support the 6 GHz band, move to it. The 6 GHz spectrum is massive, requires no DFS in most residential setups, and is currently wide open compared to the congested 2.4 GHz and 5 GHz bands.

How has the stability been since you made the switch? Are you noticing total dropouts, or just choppy ping spikes?

And this latest version won't load on it? 

 

Of course not.

And I've updated the Firmware to the latest 1.0.17.144

 

Your router does show RAX54S or RAX54Sv2 on the label?

 

Does Amazon indicate you had ordered and received a RAX54Sv2?

 

Was this an Amazon "open-box" deal, or was the box and the inner bag opened before you received it?

 

Does Serial number and MAC address printed on the labels match to the Serial number and MAC address on the router Web UI?

 

In case all this does not match, this looks like a classic, albeit frustrating, case of hardware swapping fraud (sometimes called "box switching").

 

Here is a breakdown of what is happening, why the firmware won't work, and how you can verify if you've been scammed.

The Core Issue: Hardware vs. Firmware

The Netgear Nighthawk RAX54S and the RAX54Sv2 (Version 2) may look identical on the outside, but they are entirely different machines under the hood.

• RAX54S (v1): Uses a specific chipset and runs firmware in the v1.0.x.xxx family.
• RAX54Sv2: Uses a completely different processor/chipset design and runs firmware in the v1.1.x.xxx family.

Because the underlying hardware architecture is different, you cannot cross-load the firmware. The router's system will reject it to prevent "bricking" (permanently ruining) the device.

The "Swapped PCB" Scam Explained

What the forum user is suggesting is a known issue with Amazon returns:

1. A "bad actor" buys a brand new RAX54Sv2 from Amazon.
2. They take it home, open the case, and swap the internal circuit board (PCB) of their old, broken, or cheaper RAX54S (v1) into the new v2 plastic shell. (Alternatively, they just put their old v1 router inside the new v2 box).
3. They return the Franken-router to Amazon for a full refund.
4. Amazon’s return department checks that a router is in the box, misses the internal swap, and restocks it—often selling it as an "Open-Box" deal or even mixed back into "New" inventory.

Ultimately, the innocent next buyer (VRixxo) ends up with a router that says "v2" on the outside, but is actually a "v1" on the inside.

How to Verify if You Were Scammed

If you suspect this has happened to you, perform these three quick checks:

• Check the Web UI vs. Physical Label: Log into the router's admin dashboard (usually 192.168.1.1). Look at the Serial Number and MAC address listed digitally on the screen. Now, look at the sticker on the bottom of the actual router. If they do not match, the hardware has been swapped.
• Check the Firmware Prefix: If the router's dashboard says you are on v1.0.17.144 and it refuses to update to a v1.1.x version, your router is physically a v1, regardless of what the box or plastic shell says.
• Inspect the Packaging: Look for signs of tampering. Was the shrink-wrap missing? Were the internal plastic bags taped shut rather than heat-sealed?

What to Do Next

If the numbers don't match, contact Amazon customer support immediately. Do not try to force the firmware. Tell them explicitly: "I received a fraudulent return. The item inside the box does not match the product description, and the internal serial number does not match the external label." Amazon is usually very quick to issue a replacement or refund for this specific issue.
