HP Smart Says "Something Went Wrong" During Setup: How to Get Past It

"Something went wrong" is HP Smart's catch-all message and it tells you almost nothing, which is exactly why it is so frustrating. In practice it comes from a short list of causes: the device running the app is on a network band the printer cannot see, the printer has dropped out of setup mode, the app is carrying a stale cached state from an earlier attempt, or something is blocking the account and cloud steps that HP setup now requires.

Quick fixes first

1. Put your phone or laptop on the 2.4 GHz network. If your router shows one merged name, this is the single most valuable thing you can change.
2. Restore the printer's network defaults so it re-enters setup mode: on models with a panel, Setup, then Network Setup, then Restore Network Settings. On button-only models, hold the Wireless and Cancel buttons together until the wireless light flashes.
3. Force-close HP Smart, then reopen it. On a phone, swipe it away from the app switcher rather than just going to the home screen.
4. Turn off any VPN, and move the printer, router and device into the same room for the setup.
5. Restart all three - router, then printer, then device - waiting for each to settle before starting the next.

Why HP Smart setup fails

Setting up an HP printer involves several steps that all have to succeed: the app finds the printer over Bluetooth or on its temporary setup network, hands over your Wi-Fi credentials, the printer joins your network, the app finds it again on that network, registers it with your HP account, and finally installs a print driver or profile. A failure anywhere in that chain produces the same generic message.

The most common break point is the band. Most HP consumer printers - the DeskJet, ENVY and entry LaserJet ranges - use 2.4 GHz Wi-Fi only. If your phone is connected to 5 GHz, the app may find the printer over Bluetooth, hand over credentials for a network the printer cannot see, and then fail when it tries to find the printer again.

The second is setup mode timing out. A new HP printer broadcasts its own setup network for roughly two hours after first power-on. Miss that window and the printer stops advertising itself, so the app finds nothing.

The third is the account step. HP setup now expects an HP account sign-in in most regions. If a VPN, a corporate network, a DNS-level ad blocker or a strict firewall interferes with that, setup fails after the printer has already joined the network - which is why people often find the printer works for printing but the app still reports a failure.

Fix 1: Sort out the Wi-Fi band

Open your phone's Wi-Fi settings and check which network you are on. If your router publishes separate names such as "Home" and "Home-5G", join the 2.4 GHz one for the duration of setup.

If your router publishes a single merged name across both bands, you have three options: temporarily disable the 5 GHz radio in the router settings for ten minutes, temporarily create a separate 2.4 GHz guest-free network name, or move far enough from the router that your phone drops to 2.4 GHz naturally. The first is cleanest if you have access to the router.

Once setup is complete you can undo the change; the printer keeps the network it joined.

Fix 2: Put the printer back into setup mode

This is essential if the printer has been powered on for more than a couple of hours, or if a previous attempt partly succeeded.

On models with a touchscreen or menu panel: go to Setup, then Network Setup, then Restore Network Settings (some models label it Restore Network Defaults). Confirm. The printer restarts and re-enters setup mode with the wireless light flashing.

On button-only models such as many DeskJet units: press and hold the Wireless button and the Cancel button together for about five seconds until the wireless light begins to flash. Some models use Wireless plus the Power button - check the label on the printer's rear or the quick start guide.

You have roughly two hours from that point. Do the setup immediately rather than coming back to it.

Fix 3: Clear the app's cached state

A half-finished setup leaves data behind that trips the next attempt.

On iPhone or iPad: delete HP Smart, restart the device, then reinstall from the App Store. On Android: open Settings, then Apps, then HP Smart, then Storage, and choose Clear storage as well as Clear cache - or simply uninstall and reinstall. On Windows 11: open Settings, then Apps, then Installed apps, find HP Smart, choose Advanced options and use Reset. If that fails, uninstall and reinstall from the Microsoft Store.

Also remove any half-added printer entry. On Windows 11, open Settings, then Bluetooth & devices, then Printers & scanners, select the incomplete HP entry and choose Remove. On macOS 26 Tahoe, open System Settings, then Printers & Scanners and remove the entry with the minus button. Starting from nothing is far more reliable than trying to repair a partial setup.

Fix 4: Clear the path for the account step

Disconnect any VPN entirely - pausing is not always enough, since some clients keep DNS routed through the tunnel. If you use a DNS-level ad blocker such as a Pi-hole or a filtered DNS service, disable it for the setup window, because HP's registration endpoints are sometimes caught by broad filter lists.

On Windows, check Windows Security, then Firewall & network protection, then "Allow an app through firewall", and confirm HP Smart is permitted on Private networks. If you run a third-party security suite, check its firewall list too.

Corporate and campus networks frequently block the discovery protocols setup relies on. If you are on one, set the printer up on a home network or a phone hotspot first, then move it.

Fix 5: Bypass the app entirely

You do not have to use HP Smart to connect the printer to Wi-Fi. On models with a panel, use the built-in wizard: Setup (or the wireless icon), then Network Setup, then Wireless Setup Wizard, then choose your network and enter the password on the panel. Once the printer is on the network, HP Smart will find it easily, and Windows and macOS can add it directly.

On button-only models, WPS works: press the WPS button on your router, then hold the printer's Wireless button until the light flashes, and the two negotiate a connection without any app involvement.

You can also print a Wireless Network Test Report from the printer - usually by holding the Wireless and Information buttons together, or from the panel's reports menu. It tells you plainly whether the printer joined the network and what signal it is seeing.

Fix 6: Run HP Print and Scan Doctor on Windows

HP's diagnostic utility checks driver state, spooler health, firewall rules and connectivity, and fixes several of them automatically. It is a faster route to a working printer than repeated app attempts, and it reports specifically what it found rather than "something went wrong".

Where setups usually break

If nothing worked

Setup failures are software and network problems, so replacing the printer almost never helps - a new unit of the same model will hit the same router configuration. If the printer joins Wi-Fi via the panel wizard and prints from Windows or macOS, you have a working printer even if HP Smart is still unhappy, and that is a perfectly reasonable place to stop.

The exception is a printer that will not join any network, will not hold settings, and fails a Wireless Network Test Report repeatedly - that can indicate a failed wireless module, which on a consumer HP is not economically repairable. If the printer is new, this is a warranty exchange rather than a repair.

If you have run out of patience with the app, you can get help from a printer specialist to get the printer onto the network by the direct route instead.
