How to Fix an HP Printer That Won't Connect to Wi-Fi

An HP printer that suddenly drops off Wi-Fi, or won't join in the first place, usually fails for one of a few predictable reasons: your router handed out a new band, a software update reset the driver, or the printer's radio is in a confused state. The single most common culprit is the 2.4 GHz versus 5 GHz mismatch. Here's the fix order that gets most HP printers back online.

Key takeaways

• Almost every home HP printer is 2.4 GHz only, if your router merges both bands under one name, the printer can't find it.
• A power cycle of printer and router in the right order fixes a surprising number of cases.
• Restoring network defaults wipes a confused Wi-Fi state so setup can start clean.
• Band steering and MAC filtering on the router silently block printers, disable them during setup.
• Outdated firmware is a frequent cause of "won't reconnect after the router changed" problems.

Power cycle in the right order

Restarting both devices in sequence re-establishes the connection more reliably than rebooting either alone.

1. Turn the printer off.
2. Unplug the router for 60 seconds, then plug it back in and wait about 2 minutes for it to fully boot.
3. Turn the printer on.
4. Restart the computer or phone you print from.

If the printer reconnects on its own after this, the original problem was a stale connection cleared by the reboot.

Before you start, match the symptom you are seeing to its likely cause so you do not waste time on the wrong fix:

Symptom	Likely cause	Fix
Printer never finds your network	2.4 GHz band hidden behind band steering	Split bands or disable 5 GHz during setup
Was working, then a router reboot broke it	New IP address assigned, computer looks for the old one	Update firmware, reconnect, re-add on the PC
Connects but won't accept setup	Stale saved Wi-Fi credentials on the printer	Restore Network Defaults, then re-run setup
Joins network but PC can't see it	AP isolation or guest network	Put printer and PC on the same main network
Approved devices only can connect	MAC filtering on the router	Add the printer's MAC to the allow list
Reconnects, then drops repeatedly	Outdated printer firmware	Update firmware in HP Smart

This is the big one. Models like the DeskJet 2700 and 2800, Envy 6000, OfficeJet 3800, and most LaserJet M-series printers only support 2.4 GHz Wi-Fi. If your router broadcasts 2.4 GHz and 5 GHz under the same network name with band steering on, the printer often gets pushed toward 5 GHz and fails.

1. Log in to your router (commonly 192.168.1.1 or 192.168.0.1).
2. Either give the two bands separate names, for example HomeWiFi and HomeWiFi-5G, or temporarily disable 5 GHz during printer setup.
3. Connect the printer to the 2.4 GHz network.
4. Re-enable 5 GHz afterward if you split the names; the printer stays on 2.4 GHz.

Restore the printer's network defaults

A printer stuck with bad saved Wi-Fi credentials needs its network state wiped before it can rejoin.

• Printers with a screen: go to Setup then Network Setup then Restore Network Defaults.
• Printers without a screen (DeskJet 2700e, 4100e, Envy 6000e): press and hold the Wi-Fi button and the Cancel (X) button together for about 5 seconds until the power light flashes.

This clears the saved network so you can run setup fresh in the HP Smart app.

Check router settings that block printers

If the printer still won't join, the router may be actively refusing it.

• MAC filtering blocks any device whose hardware address isn't approved, including a printer you just reset. Disable it during setup or add the printer's MAC to the allow list.
• Band steering (covered above) pushes the printer to a band it can't use.
• AP isolation or guest mode stops devices on the network from seeing each other, so your computer never finds the printer. Make sure the printer and computer are on the same network, not a guest one. These overlap with the broader secure home router checklist, where the same toggles matter for security.

Update the printer firmware

Out-of-date firmware is a surprisingly common cause of a printer that won't reconnect after a router change.

1. Open HP Smart and tap your printer.
2. Go to Advanced Settings then Tools then Printer Updates.
3. Install any available firmware.
4. Reconnect to Wi-Fi if prompted.

Factory reset as a last resort

If nothing else works, a full factory reset wipes every setting so you start completely fresh.

1. Search "your model factory reset" on hp.com for the exact button sequence, most involve holding a button combination for 5 to 10 seconds while powering on.
2. After the reset, open HP Smart and run setup as if the printer were brand new.

Confirm the fix

Print a test page from the computer, not just the printer's own menu, so you confirm the whole path works. If the printer connects but jobs still won't print, the problem has moved from networking to the print queue, that's the territory of a printer stuck offline in Windows 11 and the related print spooler that keeps stopping.

What to do right now

If the printer is offline right now, run this sequence and stop as soon as a test page prints:

• Power cycle in order: printer off, router unplugged 60 seconds then back on, printer on, then restart your PC or phone.
• If it still cannot find the network, split your router's bands into separate names and connect the printer to the 2.4 GHz one.
• Restore the printer's network defaults (or hold Wi-Fi plus Cancel for five seconds on screenless models), then re-run setup in HP Smart.
• During setup, temporarily disable MAC filtering, band steering, and guest or AP isolation on the router.
• Update the printer firmware in HP Smart, since a stale build is a common cause of "won't reconnect after the router changed."
• Print a test page from the computer, not the printer's own menu, to confirm the whole path works.

When it connects but still won't print

A printer that joins the network but ignores jobs has moved from a networking problem to a queue or driver problem. The Wi-Fi light being solid tells you the radio side is fine, so stop fiddling with router settings. The usual culprits are a paused print queue, a stalled spooler service, or the printer showing as offline in Windows even though it is online on the network. Those are different fixes entirely, and chasing them as Wi-Fi issues just wastes time.

Frequently asked questions

Why won't my HP printer find my Wi-Fi network?

Most likely because your printer is 2.4 GHz only and your router merges both bands under one name with band steering on. Split the bands into separate names or disable 5 GHz during setup, then connect the printer to the 2.4 GHz network.

What does 'Restore Network Defaults' do?

It wipes the printer's saved Wi-Fi credentials and network settings so you can run setup cleanly. It doesn't reset ink levels, page counts, or other preferences, just the network state.

My printer was working, then a router reboot broke it, why?

A router restart often assigns the printer a new IP address, and your computer is still looking for the old one. Update the firmware, reconnect the printer, and re-add it on the computer so it picks up the new address.

Do I need to disable MAC filtering permanently?

No. Only disable it during setup if it's blocking the printer, then either re-enable it after adding the printer's MAC address to the allow list, or leave it off if you don't rely on it for security.
