The "Where's the WPS PIN?" Question Has Three Answers

A client called me at 3:00 PM on a Thursday. She needed 300 booklets printed, bound, and delivered by noon Friday. Her Brother MFC—reliable for two years—had gone offline that morning after a network update, and nobody on her team could get it back online. So she did what most people do: she searched "brother printer wps pin location" and hoped for a magic answer.

The printer wasn't broken. It was connected to the guest network instead of the main one, and the guest network's password had rotated overnight. We fixed it in 12 minutes. But that afternoon cost her four hours of panic.

In my role coordinating print production for B2B clients, I've handled more printer emergencies than I can count—47 rush orders in one quarter alone, a handful of which nearly derailed because a printer wouldn't connect. One of those was a $15,000 project with a penalty clause attached. The panic is real. So let me save you the trial and error: if you're searching for how to connect WiFi to a Brother printer, there is no single answer. But there are three scenarios. Find yours, and the fix is straightforward.

Scenario 1: Your Router Has a WPS Button (Skip the PIN Entirely)

If your router has a physical WPS button—usually labeled "WPS" with a circular arrow symbol—you don't need a PIN at all. This is the fastest route.

  1. On your Brother printer, go to Network → Wireless LAN → WPS.
  2. Select the WPS option. The printer starts searching for a router.
  3. Within two minutes, press the WPS button on your router.
  4. Wait. The printer and router handle the rest automatically.

Done. That's the whole process.

One catch: if nothing happens within a minute, don't assume the printer is defective. WPS is frequently disabled on business-grade routers, and IT teams often turn it off deliberately—the protocol has known security weaknesses, and the Wi-Fi Alliance itself has acknowledged vulnerabilities in the WPS PIN method. A button that won't connect usually means WPS is blocked at the network level. That puts you in Scenario 2 or 3.

Scenario 2: Your Router Asks for a PIN (Where to Find It)

Some routers don't have a WPS button at all. Instead, their admin interface asks you to enter an 8-digit PIN generated by the device you're trying to connect. That's the WPS PIN everyone searches for. Here's where to find it, depending on your Brother model.

Brother Printers with a Display (MFC and HL Series)

  1. Press Menu on the printer.
  2. Go to Network → Wireless LAN → WPS.
  3. Choose WPS with PIN (not "Push Button Method").
  4. The printer generates a fresh 8-digit PIN and displays it on the screen.
  5. Enter that PIN into your router's WPS settings page.

Important: the PIN is generated each time you select this option. It is not stored anywhere on the device. So if you're hunting for a printed label with a PIN, stop. You won't find one on these models.

Brother Label Printers (QL-800, QL-810W, QL-820NWB)

This is where the common advice gets confusing. On QL-series label printers, the WPS PIN actually is printed on a sticker on the bottom of the device. Flip it over. Look for an 8-digit number near the serial number. That's your WPS PIN.

(Should mention: that's not the same as the "Network Key" or "Password" also listed on the sticker. I've watched people enter the wrong one three times and get locked out of the router's admin page. Different stickers, different purposes.)

If Your Model Doesn't Have a PIN Option

Some entry-level Brother printers support push-button WPS but not the PIN variant. If "WPS with PIN" isn't an option in your printer's menu, stop hunting for a PIN that doesn't exist. Go to Scenario 3. It's the more reliable path anyway.

Scenario 3: No WPS (or WPS Keeps Failing) — Use the Setup Wizard

Here's a contrarian take: WPS is not the best way to connect a Brother printer. It's convenient when it works, but it's fragile, and it has the security concerns I mentioned. For any business setting, I recommend the Setup Wizard method instead. It's steadier, works with any router, and requires zero changes to your router settings.

  1. On the printer, go to Network → Wireless LAN → Setup Wizard.
  2. The printer scans for available networks. Select your network's name (SSID). If it doesn't appear, move the printer closer to the router, or check whether SSID broadcast is disabled.
  3. Enter your WiFi password. Careful—it's case-sensitive. I've typed mine in lowercase enough times to know.
  4. Confirm. The printer connects, and you're done.

This takes about four minutes, and it's the method we now use as the default for every client installation. We switched our standard procedure in early 2024, and connection-related support calls have dropped noticeably since. At least, that's been my experience across twenty-plus Brother printer setups for clients.

One important caveat for B2B environments: if your office network uses enterprise authentication (PEAP, EAP-TLS, a captive portal—anything requiring a username or certificate in addition to a password), neither WPS nor the Setup Wizard method will work. You'll need your IT admin to configure the printer for the corporate network, or connect it via ethernet. Don't spend an afternoon trying to make WPS work on a network engineered to block it.

Security note: the Wi-Fi Alliance's documentation and multiple government security advisories recommend disabling WPS PIN mode in enterprise environments. If your company's network has WPS blocked, that's a deliberate policy, not a malfunction.

Why Getting This Right Actually Matters

A former client once paid $180 for an on-site "printer specialist" visit. The technician arrived, changed one router setting, and left. Twenty minutes, billed as a minimum callout. The issue? The router broadcast two nearly identical network names—one standard, one with "Guest" appended—and the printer had quietly joined the guest network. No defective hardware. No worn-out parts. Just the wrong network selected.

That $180 could have been $300–500 more if they'd decided to replace the printer entirely, which crosses a lot of people's minds when a printer "just stops working." It wasn't broken. The WiFi connection was.

I'll say it plainly: the cheapest path is rarely the one with the lowest sticker price. It's the method that gets the printer connected reliably the first time and stays connected afterward. That's why I steer people toward the Setup Wizard even when WPS is available. The few extra minutes upfront prevent an identical troubleshooting session three weeks later, when the WPS connection drops again for no apparent reason.

And downtime is the real cost. Missed deadlines, rush shipping premiums (typically 25–50% over standard pricing for 2–3 day turnarounds, based on published pricing as of January 2025), overpriced same-day printing across town, and the erosion of client trust. A ten-minute fix using the right method is worth more than any "saving" that leaves you staring at a printer that refuses to connect.

Which Scenario Are You In? (30-Second Checklist)

Before you go in circles, here's how to find your path:

  • Your router has a physical WPS button → Try Scenario 1 first. It's fast and usually sufficient.
  • Your router's admin page asks for a WPS PIN → You're in Scenario 2. Find or generate the PIN using the steps above.
  • No WPS button, or WPS fails repeatedly → Go to Scenario 3. The Setup Wizard only needs your WiFi password.
  • WPS connected once, but the printer keeps dropping offline → Reconnect using the Setup Wizard method. This tends to stabilize the connection.
  • Printer is on a corporate/managed network → Call your IT admin. Seriously. Enterprise networks block WPS for good reason.

In my experience, roughly two-thirds of the people asking about the Brother WPS PIN actually belong in Scenario 3. They've heard the term "WPS PIN" from a search snippet, but their router doesn't even use WPS. The Setup Wizard solves their problem in ten minutes. I've seen a brand-new printer sit in a corner for a week, blinking aggressively, when a 10-minute Setup Wizard run would have had it fully operational. Don't be that person.

Still stuck? Print a Network Configuration Report on your Brother printer (on most models: hold the Go button for five seconds, or navigate to Network → Print Settings). It shows the printer's IP address, the network it's currently connected to, signal strength, and any error codes. Write down the error code before calling Brother support. That one page will save you half an hour of phone troubleshooting.

And if you got here while troubleshooting a different brand entirely—say, searching how to get HP printer back online—the diagnosis flow is the same: verify the printer has a valid IP address, restart both the printer and the router, and re-run the wireless setup. The menus differ by brand, but ninety percent of "offline" printer problems are network problems wearing a printer costume.
