The Brother HL-L2370DW is this wireless monochrome laser printer, it supports both WiFi and wired (Ethernet) connections. So wheather you are doing the setup for the first time, or you are reconnecting after a network shuffle, this guide kinda covers every method , including what to do when your Brother HL-L2370DW won’t connect to WiFi .

Method 1: Wireless Setup Wizard (Recommended)

The Wireless Setup Wizard kinda walks you through putting in your network name, (SSID) and then the password, straight from the printer control panel. This is the most reliable method for a brother hl-l2370dw wifi setup because it works with any router — including those that don’t support WPS.

What you’ll need

  • Your WiFi network name, SSID
  • Your WiFi password
  • Make sure the printer is powered on and close enough to your router

Steps

  1. Press the Menu button on the printers control panel.
  2. Then, use the ▲ / ▼ arrow keys to sort of get to Network, and after that hit OK.
  3. Find WLAN, then press OK.
  4. Choose Setup Wizard, then press OK.
  5. When the screen shows “Enable WLAN?” press OK (just confirm it) and the printer will begin looking for available networks.
  6. With the arrow keys, pick your WiFi network name (SSID) from the list, then press OK. If your SSID is not showing up, go down to and type it in yourself.
  1. Type your WiFi password on the keypad, (use the arrow keys to move, OK to pick characters) then press OK.
  2. Press OK one more time to apply the setup.
  3. The printer should restart and try to connect. Wait a little, once it’s done you’ll see a Connected message.

To make sure it really worked: print a Network Configuration Report by doing Menu > Print Reports > Network Config > OK. Check the “WLAN” line where it should say “Connected” and you should also see a usable IP address.

Method 2: WPS (One-Button Setup)

WPS (Wi-Fi Protected Setup) can let you hook the printer to your router without typing in a password which is pretty handy if your router actually supports WPS.

First, do a quick check. Find the WPS button on your router, it’s often labeled “WPS” or shown with that little WPS symbol. Some routers don’t have WPS at all so if you’re not sure just check your router’s documentation, ok.

Push-Button WPS

  1. Press Menu on the printer.
  2. Go to Network > WLAN > WPS/PushButton, then press OK.
  3. When it ask if you want to begin WPS, press OK.
  4. Within 2 minutes, press the WPS botton on your router
  5. The printer should connect by itself. You’ll see a “Connected” message to confirm it worked, and you’re done.

WPS PIN Method

If your router wants a PIN for WPS, instead of you pressing a button, use this route:

  1. Press Menu on the printer.
  2. Go to Network > WLAN > WPS/PIN Code, then press OK.
  3. On the printer screen you will see an 8 digit PIN, it’s displayed there.
  4. Next, go ahead and open your router admin panel, it’s often 192.168.1.1 or 192.168.0.1… it really depends.
  5. Look for the WPS pin area, it is usually under Wireless Settings > WPS.
  6. Enter those 8 digits from the printer display and then confirm it on the router, just press the button there.
  7. After a few minutes the printer connects.

What is the WPS PIN on HL-L2370DW?

It’s that 8-digit code that gets generated dynamically every single time you start a WPS/PIN Code connection from the printer’s menu. The value shows up on the printer LCD during that WPS PIN setup step, and no, it is not some steady number you can find printed on the device.

Method 3: USB Cable Setup

If you want to set up the wireless link from your computer, you can use a USB cable for a bit during the initial setup, just temporarily. This approach relies on Brother’s installer software, it’s kind of straightforward but you do have to follow along.

Steps:

  1. Go to Brother’s support site and download the whole driver + software package for the HL-L2370DW .
  2. Start the installer , and when it asks about the kind of connection , pick the Wireless Network Connection option, not the other one.
  3. When you get to that screen where it asks how you want to connect, choose Temporarily use a USB cable, even if you plan to stay wireless after.
  4. Now connect the printer to your computer using a normal USB-A to USB-B cable, like a basic ordinary cable, no special adapters or extras .
  5. The installer should find the device and then walk you through choosing your WiFi network plus entering your password, pay attention here.
  6. After the wireless settings get sent to the printer, unplug the USB cable.
  7. The printer should switch to WiFi automatically and the installer finishes the driver configuration.

This technique works especially well when your network has more strict security options, like WPA3, or if your SSID is hidden, because then the control panel wizard can feel more difficult to use.

How to Connect via Wired (Ethernet) Setup

For a brother hl-l2370dw wired setup, the printer has a built-in 10/100BASE-TX Ethernet port on the back.

Steps:

  1. Plug one end of a standard Cat5e or Cat6 Ethernet cable into the LAN port on the back of the printer.
  2. Plug the other end into an available port on your router or network switch , it should click in nicely.
  3. Power on the printer. It usually gets an IP address automatically through DHCP .
  4. Print a Network Configuration Report (Menu > Print Reports > Network Config > OK) so you can confirm which IP address it grabbed.
  5. Install the printer driver on your computer:

– Download the Full Driver & Software Package from Brother’s support site.

– Run the installer and choose Wired Network Connection.

– The setup will detect the printer on the network automatically, it’s fairly quick.

Note: If you’re moving from WiFi to Ethernet, or the other way around , you might need to disable the unused interface. Go to Menu > Network > Wired LAN or WLAN and set the interface you arnt using to Off.

How to Connect Brother HL-L2370DW to WiFi on Mac

The whole process on macOS kinda has two parts, first you set up the printer’s WiFi (using one of the methods above), and then you add it inside System Settings, not too hard but it is steps.

Step 1 — Get the printer’s WiFi going

Use Method 1, the Wireless Setup Wizard, from the printer’s control panel. This helps connect the printer to your network. This part is basically identical whether you are on a Mac or a PC.

Step 2 — Download the Mac driver

  1. Go over to support.brother.com and type in HL-L2370DW, search a bit around.
  2. First, pick your macOS version, then go ahead and download the Full Driver and Software Package for Mac.
  3. After that, open the .dmg file you grabbed and run the install wizard.
  4. When the prompt comes up, choose Wireless Network Connection and then follow what the screen says, step by step.

Step 3 — Add the printer on macOS

If the setup doesn’t just add the printer by itself:

  1. Open System Settings > Printers & Scanners,
  2. Tap the + (Add Printer) thingy,
  3. Your HL-L2370DW should show up in the list, if it doesn’t just go ahead and look it up by name, or use the IP address,
  4. Select it then press Add.

Using AirPrint: The HL-L2370DW also does AirPrint on its own, no fuss. Once the printer is on WiFi, you can add it through Printers & Scanners > Add Printer > AirPrint, and you don’t really need to install a driver. Do note though, print quality and some features may end up being a bit more limited than what you get with the full Brother driver.

Brother HL-L2370DW Won’t Connect to WiFi — How to Fix

If your brother HL-L2370DW does not seem to connect to wifi, usually it’s one of a few things. Like , very often, it’s the same culprit over and over.

First thing to check, your WiFi band 2.4 GHz (has to be)

The Brother HL-L2370DW is only okay with 2.4 GHz wireless. It will not play nice with 5 GHz networks. This is honestly the most frequent reason the connection fails.

How to look it up and sort it out:

  • Go into your router’s admin panel and make sure the 2.4 GHz network is turned on.
  • If your router uses one SSID for both bands, like “band steering” or something similar, the printer may attempt the 5 GHz side and then it stalls. The fix is splitting them into two different SSIDs (for example “MyNetwork_2.4G” and “MyNetwork_5G”), then connect the printer to the 2.4 one.
  • Also confirm the printer is not too far from the router. Those walls and distance they weaken 2.4 GHz signal pretty fast. Try moving the printer closer just for a quick test.

Other stuff to double-check, just in case

  • WPA3-only setups – the HL-L2370DW supports WPA and WPA2 but if you’re on WPA3 only networks it can cause problems. Just switch the router to WPA2 / WPA3 mixed mode, so it does not start acting up, again.
  • MAC address filtering — if the router is blocking devices by MAC address, put the printer’s MAC address into the allowed list. You can grab the MAC from the Network Config Report.
  • IP conflicts – if another gadget is using the same IP, everything goes strange real quick. Set a static IP, or use a DHCP reservation in the router, so the printer keeps the same address, steady.

Reset Network Settings

If the printer is holding onto weird network settings already saved (like after a password change, or when a router gets replaced), then resetting network settings is basically a fresh start.

To reset network settings on the HL-L2370DW:

  1. Press Menu on the printer.
  2. Go to Network, then press OK.
  3. Scroll down to Network Reset, press OK.
  4. Tap 1 (or Yes) to confirm, the reset.
  5. The printer should restart with the factory network settings.

Once it’s done, go through the Wireless Setup Wizard (Method 1) again, so you can re-connect to your network. And if you want to clear more than that too, not just the network, then head to Menu > Initial Setup > Reset > All Settings > OK > Yes.

Reinstall the Driver

A broken or kinda old driver can mess up the whole proper communication between your computer and the printer, even if the printer is already sitting there on WiFi. Reinstalling the driver often helps, especially when the printer shows as “online” in the network, but your computer still just won’t really print (or it stalls, or starts acting weird).

On Windows:

  1. Open Settings > Apps (Windows 10/11), and then remove any Brother HL-L2370DW software that shows up in that list, if it shows up.
  2. Next go to Control Panel > Devices and Printers, right click the HL-L2370DW, then choose Remove device, and it should appear there.
  3. After that, head to support.brother.com and download the latest Full Driver & Software Package, not the “smaller” one.
  4. Run the installer, and then just keep tapping through the prompts, so it gets set back up the right way.

On Mac:

  1. Head over to System Settings > Printers & Scanners, grab the printer you see, then hit the  – button to get rid of it
  2. Open Finder > Applications, take a look for any utilities connected to Brother, then drag those items into Trash, and you’re done
  3. Download again, and reinstall the latest Mac driver from Brother’s support site
  4. Add the printer again through System Settings.

Also worth trying: Brother’s Print&Scan Doctor tool (Windows) can, in quite a few cases, quickly spot and repair typical driver or connection issues by itself.

FAQs

Does the Brother HL-L2370DW have WiFi ? Yes. It includes built in 802.11 b/g/n wireless networking so it can link up to 2.4 GHz WiFi networks, no extra adapters needed. There’s also a wired Ethernet port. Plus it supports a USB direct connection. And the “DW” part in the model name, kind of hints at duplex and wireless, in other words it’s built for both.

So, about the WPS PIN on the HL-L2370DW. The WPS PIN is one 8 digit code but it’s not the same every time, like it changes. The printer will just generate a new one each time you start a WPS PIN session. So yeah, it’s dynamic not some fixed number. To see it, go Menu  >  Network  >  WLAN  >  WPS / PIN Code > OK, and then the code should pop up on the printer LCD. After you get it, type it into your router’s WPS settings within roughly 2 minutes, so the matching ends.

Next, how do you find the IP address for your Brother HL-L2370DW , honestly the quickest thing to do is print a Network Configuration Report. This is usually the easi… like it gives you the details right there, no too much fuss. Do Menu > Print Reports > Network Config > OK, then check the printout for the IP address. Another route is to open your router and look at the connected devices list, there you can see which IP got assigned to the printer.

Can it work with a WiFi extender or a mesh setup? Yes , absolutely , as long as the extender or mesh node is broadcasting a 2.4 GHz WiFi network. If possible, connect the printer to the nearest node for a more steady connection. And if your mesh system has some “stick this device to a node” type option , use it if it exists, it may help keep everything consistent.

Finally, try switching the HL-L2370DW from USB over to WiFi, run that Wireless Setup Wizard. You can go Menu > Network > WLAN > Setup Wizard, an then just follow what it asks, pretty much step by step, and yeah it should find things on its own for you. After that, add the printer in your computer’s printer settings, either by entering the printer’s IP address, or let the Brother installer find it on the network automatically. You can leave the USB cable there too , it can still be used as a backup, both modes can be active and it should still work in practice.
