Internet not working: the full fault ladder, from one red light to a formal complaint
A worked order for finding the fault, what to tell support so they cannot skip you, and how to make escalation bite.

Support scripts are designed to be run in order and to end quickly. Arrive having already completed steps one to four, with the exact light state and your account number, and the ticket starts three stages later. That is the difference between an hour of restarting and a booked visit.
Do not escalate on feeling. Escalate on a reproducible pattern: the same fault at the same hours, on a wired test, five times, recorded. That is a fault report a network team cannot route back to you.

Internet not working - what decides it
Write the pattern down before you call: what fails, when, for how long, and what was different when it worked. "It drops at 8 pm and recovers in a few minutes" is a diagnosis. "Internet is bad" is a callback loop.
du home internet not working - the 5-minute check
Steps
- Check the light pattern first: power, WAN/optical, Wi-Fi. Red optical = line fault, not a settings problem.
- Restart once - unplug the router for 30 seconds, not 5, then wait 3 minutes for the ONT to re-register.
- Look for a known outage in your area before touching settings (du app > support, or the status thread for your building).
- If the optical cable or the small white ONT box was knocked (cleaning, moving furniture), reseat the blue-tipped fibre connector gently - never bend it.
- Still red after a reboot? Open the du app and raise a fault so the ticket timestamp starts now; escalate to us on WhatsApp and we will chase the job number.

Router red light: what each colour actually means
Steps
- Read the label next to the light: LOS, PON/Optical, WAN, Internet, Wi-Fi. PON solid green = line fine.
- LOS red: check the thin fibre lead for a kink or a pulled connector, then reboot once. Do not open the ONT.
- WAN red: your account may be suspended or the PPPoE credentials dropped - check for an unpaid bill or a recent plan change, then reboot.
- Internet red with green WAN: forget the network on one device and reconnect; if every device fails, clone the DNS to 1.0.0.1 / 8.8.8.8 in the router LAN settings.
- Send us a photo of the lights on WhatsApp and we will tell you which queue the ticket belongs in - fault, billing, or settings.

How to run a speed test that du will accept
Steps
- Connect one device with an Ethernet cable directly to the router.
- Turn off VPN and any other heavy device on the network.
- Run the du app speed test (or a test that stores a result ID) three times: morning, 8pm, midnight.
- Screenshot the result IDs plus your account number before you open the ticket.
- If the wired figure is under half your tier at midnight, that is a line fault - request a technician visit with those IDs.

Is du down right now?
Steps
- Check the du app status/support screen for a logged incident against your line.
- One neighbour plus one device failing = likely area issue; one device failing = local issue.
- Look for the same symptom in your building group chat or the public outage threads.
- Note the start time; credits are calculated from when the fault began, not when you called.
- Send us the area and the router lights and we will tell you whether it is already a known incident.

Internet keeps disconnecting every few minutes
Steps
- Note the time between drops; if it is consistent, it is almost always line-level, not your laptop.
- Touch the router: hot units throttle and drop. Add airflow or move it out of the cupboard.
- Check for an old firmware banner in the router admin page (192.168.1.1 for most du units).
- If you have two SSIDs from one router or an extender, name them apart and pin the important device to the router itself.
- Ask for an optical power reading on the fault ticket - dBm out of range means a splice or patch problem, not a settings problem.

Activating a new du SIM or line
Steps
- Register with Emirates ID (residents) or passport (visitors) at a store, kiosk or through the app.
- Insert the SIM, restart the phone, wait for the network SMS - that is the activation signal.
- For a postpaid number transfer, complete the port request with the losing operator details.
- If the phone shows "no service", test the SIM in another handset to separate device from line.
- Visitors: a tourist line has a fixed life; extend or convert before it expires.

Checklist before you contact support
- Note the exact indicator pattern before touching anything
- Run one wired speed test and save the result
- Check the outage view and screenshot it with a timestamp
- Confirm no suspension on the bill
- Power cycle once only, with 30 seconds off
- Keep one ticket number for the whole incident
- Log times and durations every day the fault recurs
Mistakes that cost people money
- Factory resetting mid-investigation so support cannot read the config
- Opening parallel tickets that each restart at step one
- Accepting a fix confirmed at 11 am for an 8 pm fault
- Describing drops as slowness, which changes the diagnosis you get back
If you need to escalate
- Only then move to the formal complaint route with the whole thread attached. Regulators ask what the operator said, so the operator answer is your document.
- Take the evidence, not the adjective: one wired test at the time the fault happens, with the date and the figure, plus the indicator state. That is what changes the queue you are put in.
- Ask for a fault record and a reference number in writing, and ask what the committed resolution time is - then do not close the ticket when someone calls to say it is done.
- If the committed time passes, ask for a supervisor and for the written response, naming the missed commitment and requesting the credit schedule.
The same ladder is used for every problems & fixes case on this site, because the order is what changes the outcome - not the words you happen to use.
What to send us on WhatsApp
For "Internet not working: the full fault ladder, from one red" specifically, lead with the symptom and the address - the rest is context a reader of this guide already has.
- Your emirate and building/unit (not just the area name)
- Whether you are on fibre or a wireless unit, and the router model if you know it
- Your account number and whether you are inside a contract term
- A photo of the router lights, and your last bill if money is the question
- What is broken or what you want, in one line

How this page was built
Plan names, prices and offer wording are read from verified resources, checked on 2026-09-12 20:27 UTC. Procedures follow the du Help Center articles named under each section. Demand figures - the search volumes in the tables - come from a licensed UAE search-demand dataset, which is where the "real searches" phrasings are taken from. Where a number depends on your address, your wall box or your contract start, the page says a quote is needed instead of estimating it. Nothing on this page is scraped from an aggregator or copied from another comparison site. Applied to Internet not working: the full fault ladder, from one red light.
Where to check it yourself
- The operator's own plan and support pages - the text your order form was written from
These pages belong to the operator and the regulator - open them side by side with your own bill or app before acting on anything here.
Verify this yourself in two minutes
- Prices and inclusions: the operator's own plan page for your emirate, then the same figure on the order form you signed.
- Your line state: the My du app - Account > Services shows suspension, bar, data cap and contract end.
- Faults in your area: My du app > Support > Outage status, or 155 from a du mobile (free).
- Anything regulatory (billing disputes, escalation): TDRA - your complaint must cite the ticket number du gave you, dated.
