Start with AT&T’s outage lookup for your service address or account. If AT&T reports an interruption, monitor its updates rather than trying to repair the provider’s network from home. If no outage is reported, compare several devices, test a wired connection when possible, and determine whether the failure affects your internet service, only Wi‑Fi, one room, or one device. Those checks narrow the cause, but none proves by itself that the fault is inside or outside your home.
The fastest way to separate an AT&T outage from a home Wi‑Fi fault
Use this order so you do not spend time changing wireless settings during a provider interruption:

- Check AT&T’s outage status. Open AT&T’s outage lookup or use the AT&T app. You may need to sign in to see account-specific service information, outage details, or alerts.
- Compare devices. Check whether phones, computers, televisions, and other connected equipment fail together or whether only one device is affected.
- Compare wireless and wired access. If available, connect a computer directly to the gateway with Ethernet and test the internet. This is a practical diagnostic comparison, not a guarantee of where the fault is.
- Restart the gateway or modem correctly when no outage is reported, following the instructions for your equipment and service type.
- Investigate Wi‑Fi coverage or a device if the gateway remains connected but only a room, device, or wireless connection has trouble.
- Use account-specific checks or contact AT&T if service still fails. A clear outage page does not establish that every localized line or equipment fault is absent.
| What you observe | What it points toward | Best next check |
|---|---|---|
| Several devices lose internet access, including a device connected by Ethernet | A broader service, line, gateway, or account problem is more plausible | Check AT&T status, then follow account and equipment troubleshooting |
| Devices stay connected to Wi‑Fi but cannot reach the internet | The gateway’s internet connection, service, or DNS/browsing path may be failing | Test another device and Ethernet, then restart the gateway if no outage is listed |
| Only wireless devices fail while Ethernet works | A Wi‑Fi configuration, radio, interference, or coverage problem is more plausible | Check the affected device, room, gateway placement, and Wi‑Fi controls |
| Only one device fails | That device’s settings, software, adapter, or saved network profile may be responsible | Forget and rejoin Wi‑Fi, restart the device, and test another network if possible |
| Service works near the gateway but not in one room | A local coverage weak spot is more plausible | Check placement and coverage tools before considering a range extender |
These symptom patterns are clues rather than conclusive diagnoses. AT&T separates “Slow connection,” “No connection,” “Can’t browse,” and “Intermittent Wi‑Fi” in its support materials, which is useful because a Wi‑Fi complaint does not always mean the same underlying failure.

How to check
Go to att.com/outages or open the AT&T app. Enter or select the affected service and address when prompted. Sign in if AT&T requests it; account access can provide a more specific result than a general location check. The outage service also offers alert and update options where available.

Record what the page says and when you checked. If an interruption is listed, follow the status messages and restoration guidance. Repeatedly rebooting equipment or buying a new router will not repair an interruption in AT&T’s outside network.
What “no outage” means
A result saying that your area is not in a reported outage is a first screening result, not proof that AT&T’s network is healthy all the way to your gateway. A newly developing fault, a highly localized line problem, an account issue, or equipment failure may not appear as a public outage. Continue with device and connection comparisons when service remains unavailable.
AT&T’s outage information and troubleshooting pages have different update dates and may present different restart estimates. Treat the status as current reported information for the selected account or address, not as a promise that every connection in the area is unaffected.

Test more than one device
Try at least two devices that normally use the same gateway. Check a phone or tablet over Wi‑Fi and a computer or television. If all of them fail at roughly the same time, the problem is less likely to be a single device. If one device works while another does not, concentrate first on the failing device rather than changing the whole network.

Also distinguish between “connected to Wi‑Fi” and “has internet access.” A device can show a Wi‑Fi connection to the gateway while the gateway itself cannot reach AT&T, so the wireless symbol alone does not confirm that internet service is working.
Use Ethernet as a comparison when possible
Connect a compatible computer directly to a gateway Ethernet port, temporarily if necessary, and load several known websites. Turn off that computer’s Wi‑Fi while testing so it cannot silently switch back to wireless. Then compare the result with a device in the same home over Wi‑Fi.
- Ethernet and Wi‑Fi both fail: investigate outage status, the gateway’s service connection, account status, and equipment.
- Ethernet works but Wi‑Fi fails: the internet feed is reaching the gateway, so focus on wireless settings, interference, coverage, or the affected devices.
- Ethernet works and only one wireless device fails: troubleshoot that device’s Wi‑Fi profile, operating system, adapter, or security software.
This wired-versus-wireless method is practical troubleshooting reasoning; it is not an AT&T guarantee that a particular result identifies one exact component.

Test Wi‑Fi beside the gateway, then in the room where the failure occurs. A connection that is reliable nearby but drops or becomes unusable at a distance points toward coverage, walls, interference, or gateway placement. A failure in every room, including beside the gateway, points back toward the gateway, service connection, or account.

Step 3: Restart the AT&T gateway or modem safely
If no outage is reported and your comparisons suggest the gateway or connection is stuck, AT&T recommends restarting the gateway, All‑Fi Hub, or modem. Use the equipment-specific instructions if they differ. A restart interrupts internet-dependent phone, television, security, and other services while the equipment is offline.
General AT&T restart procedure
- Unplug the gateway or modem’s power cord.
- If your equipment has an internal battery backup and AT&T’s instructions apply it to your model, remove or disconnect that battery backup as directed.
- If you use DSL and the instructions for your service call for it, unplug the telephone cord from the gateway or modem.
- Wait at least 20 seconds with the equipment disconnected.
- Reconnect the battery backup if you removed it.
- Reconnect the power cord, and reconnect the DSL telephone cord when applicable.
- Wait for the equipment to complete startup before judging the result. AT&T’s internet troubleshooting and gateway instructions allow up to 10 minutes; an AT&T outage FAQ gives an estimate of up to five minutes. Because the pages differ by context, do not promise one universal duration.
During startup, lights may turn off, blink, or change color. Do not repeatedly unplug the unit during that sequence. After the gateway has settled, test a nearby Wi‑Fi device and, if possible, the Ethernet connection again.
Gateway-specific and app-based checks
AT&T’s gateway restart guidance says supported models can also be restarted through Smart Home Manager. The available app workflow and supported models depend on the gateway, so use the model shown in your account rather than assuming every AT&T device has the same controls.

Step 4: Troubleshoot a local Wi‑Fi or single-device problem
If only one device cannot connect
- Restart the device and confirm Wi‑Fi is enabled and airplane mode is off.
- Move close to the gateway and try again.
- Forget the saved home network, then join it again with the current password.
- Check whether the device can join another trusted network. If it cannot, the device’s wireless adapter or software deserves attention.
- Install pending operating-system or network-driver updates when the device can obtain them safely.
Do not reset the entire gateway merely because one phone or laptop fails. A device-specific symptom is stronger evidence for local troubleshooting than for a provider-wide outage, although it still does not rule out an intermittent service issue.
If Wi‑Fi is weak in one area
Check the same device beside the gateway and in the problem room. Thick walls, floors, metal appliances, distance, and competing wireless equipment can reduce usable coverage. Place the gateway in an open, elevated, central location where your service setup permits; avoid enclosing it in a cabinet or placing it directly beside large electrical equipment.
AT&T says Smart Home Manager can help identify Wi‑Fi weak spots and connected devices. It also notes that “Each connected device in your home uses your internet and affects its speed.” A crowded network can therefore make a connection feel slow even when the AT&T line itself remains available. Pause unnecessary high-bandwidth activity while testing, then retest the affected room.

When a Wi‑Fi range extender makes sense
A Wi‑Fi range extender is a conditional option for a confirmed coverage weak spot, not a remedy for an AT&T outage or a gateway that has lost its internet feed. First verify that Ethernet or a device beside the gateway can reach the internet and that the difficulty follows a particular room. Then check compatibility with your exact AT&T gateway and placement requirements. AT&T’s support material discusses extenders and weak-spot help, but no single extender is established as compatible with every gateway or guaranteed to solve every coverage problem.

Step 5: Use the gateway lights and account checks without over-interpreting them
Indicator lights can show that a gateway is starting, connected, or attempting to connect, but their meaning varies by model and service type. A blinking or dark Broadband indicator may justify checking cables, restarting once, and reviewing the model-specific instructions. It is not, by itself, proof of an area outage.
Sign in to AT&T’s internet troubleshooting flow to see the gateway type associated with the account and any account-specific internet connection checks. Confirm that the affected service is the one selected, especially if a household has more than one AT&T line or location. Avoid changing advanced settings until basic status, power, cabling, and device comparisons are complete.
What to do in each result pattern
AT&T reports an outage
- Read the estimated restoration and update information shown for the affected account or address.
- Enable available alerts if you need notification of changes.
- Keep essential devices on another connection if available, and avoid unnecessary gateway resets.
- After AT&T reports restoration, restart equipment only if your connection does not return, then retest more than one device.
No outage is reported, and every device is offline
- Check that the gateway has power and that service cables are firmly connected.
- Run the Ethernet comparison if you can.
- Perform the AT&T restart procedure, including the 20-second wait and the full startup period.
- Use the signed-in troubleshooting tools for your gateway and account.
- Contact AT&T if wired and wireless access remain unavailable. Tell support when the failure began, whether the outage lookup was clear, which devices failed, and what happened after the restart.
Ethernet works, but Wi‑Fi does not
Keep the gateway powered and focus on wireless settings, coverage, interference, and device profiles. Test next to the gateway, inspect connected-device information in Smart Home Manager when available, and investigate a weak spot before purchasing additional equipment.
Only one room or one device is affected
Use the location and device tests first. A nearby successful test makes a localized Wi‑Fi or device cause more plausible than an area outage. Continue to monitor service if the symptom becomes intermittent or spreads to other devices.
Common mistakes that prolong the diagnosis
- Assuming a clear outage page proves there is no provider fault. Public status is reported information and may not capture every localized problem.
- Calling every failure “Wi‑Fi.” A gateway can broadcast Wi‑Fi while its internet connection is down.
- Restarting repeatedly. One proper restart followed by the complete startup period gives a more useful result than several interruptions.
- Buying an extender too early. An extender cannot repair a service outage, a failed gateway connection, or a single-device fault.
- Using another gateway model’s light instructions. Startup lights and supported app controls vary by equipment and service.
- Testing only one website on one device. Compare devices and, when possible, Ethernet so a browser or device issue is not mistaken for a network outage.
When to contact AT&T
Contact AT&T after the status check, basic cable and power checks, device comparison, and one correct restart leave the service unavailable. Provide the account or service address, gateway model, indicator-light behavior, whether Ethernet worked, how many devices were affected, and the time the problem started. If the outage page was clear, say so explicitly; that tells support you are reporting a possible localized, account, line, or equipment issue rather than an already-listed area interruption.
Seek support sooner when the gateway repeatedly loses its service connection, the problem affects every device, or the connection drops and returns in a pattern that prevents normal use. Do not claim that a particular symptom conclusively identifies AT&T’s network or your home equipment; the purpose of these checks is to give support better evidence and to prevent unnecessary purchases.
Quick Recap
A compact decision checklist
- Outage listed: follow AT&T updates; do not expect local Wi‑Fi changes to repair it.
- No outage, all devices fail: compare Ethernet, check cables and power, restart correctly, then use account support.
- Ethernet works, Wi‑Fi fails: investigate wireless settings, interference, placement, and coverage.
- One room fails: treat it as a possible weak spot and verify service beside the gateway.
- One device fails: troubleshoot that device before resetting the whole network.
- Still unresolved: contact AT&T with the test results; a clear public status does not eliminate every localized fault.
