LUZ-BLANCA-IZQUIERDA
Ring white light on left on video doorbell: no internet access
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
If the white light flashes on the left side of a Ring video doorbell during setup, the doorbell joined your wifi but could not reach Ring's servers. Check that the network has internet, unplug extra Ethernet cables from the router and retry setup.
Safety first
Stop and check this first
- The 20 second factory reset wipes the doorbell setup and you will need to add it to the Ring app again.
Safe checks you can perform
- Load ring.com on a phone joined to that wifi
- Leave only the main cable in the router
- Check whether two routers are chained at home
Leave these tasks to a qualified professional
- Do not attempt this professional task: Router review with your internet provider
- Do not attempt this professional task: Escalation to Ring technical support
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Router review with your internet provider
What they doThe provider or router maker reviews firewall, ports and protocols, and sets up bridge mode when two routers are in use.
They must show youthe firewall settings applied and whether the router was left in bridge mode.
In writingthe changes made on the router and the date of the visit.
Escalation to Ring technical support
What they doIf the network browses fine and the doorbell still cannot finish setup after a reset, contact Ring with the model and what you already tried.
They must show youthe case number and the doorbell firmware version if the app shows it.
In writingthe case number, the tests Ring reviewed and its diagnosis.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Load ring.com on a phone joined to that wifi
- Who:
- you, with your phone on the same network the doorbell picked.
- How:
- turn off mobile data so the phone only uses wifi and load ring.com in the browser, which is the test Ring suggests for this failure.
- Result that matters:
- learning whether the network has internet or the outage sits before the doorbell.
- If the page does not load:
- restart the router or call your provider before retrying setup.
- If the page loads fine:
- carry on and check the router cabling.
- Evidence to keep:
- a browser screenshot showing ring.com loaded or the error.
Evidence: Fixing setup issues
Leave only the main cable in the router
- Who:
- you, at the router, without touching the line installation.
- How:
- unplug every Ethernet cable from the router except the one linking it to the modem or wall outlet, as Ring advises, and start setup again from the app.
- Result that matters:
- ruling out another wired device interfering with the connection.
- If setup completes:
- plug the other cables back one at a time and watch whether the doorbell stays online.
- If the left white light returns:
- move on to checking for a second router.
- Evidence to keep:
- a note of the cables you removed and the setup result.
Evidence: Fixing setup issues
Check whether two routers are chained at home
- Who:
- you, looking at which network boxes are switched on.
- How:
- see whether there is a provider router with another one of yours behind it; Ring recommends using only one, or putting the provider unit in bridge mode with help from the provider or router maker.
- Result that matters:
- removing a connection cause that Ring names explicitly.
- If there are two routers:
- ask your provider to enable bridge mode and retry setup.
- If there is a single router:
- factory reset the doorbell by holding the setup button for 20 seconds and try again.
- Evidence to keep:
- a photo of the network boxes and a note of the change made.

What it means
Ring's doorbell light pattern guide explains that a white light flashing on the left side is a setup failure: the doorbell connected to wifi but could not reach Ring's servers or the internet. Ring's article on fixing setup issues files this case as 'unable to connect to internet' and suggests reviewing the firewall, ports and duplicate routers. The light alone never proves the doorbell is faulty, and other models or firmware versions may behave differently.
