Error 309 built in opener and using internet gateway.

  • Updated 1 month ago
A common problem, it seems. I have a garage opener that has MyQ built in, and I bought the gateway years ago. It worked fine, until I lost the power cord. Found one, hooked it up again, and downloaded the app again. It shows offline, as so many have. I have reset the gateway, reset my router, reset my modem, and unplugged my opener and plugged it back in. Solid green light from the Ethernet, 100% connection from my router network app. When clicking on “offline” in the app, it takes me to testing for batteries on the hub and door sensor. I do not have a hun, it is built into my garage opener. I would appreciate assistance with this.

Thank you.

Reset your home router.  MyQ will then get a new IP address and work fine.  Seems to happen after every power failure especially if you have battery backup on your garage door opener.

Thanks for trying, but this hasn’t worked. I’ve reset the router and it doesn’t fix the issue.

Sorry to hear that but it fixed mine on two occasions now. I assume the opener is connected to you’re to wifi? I reconfigured the wifi as well first but that did not fix it.

It’s not a WiFi garage opener. It’s a slightly older model that just supports MyQ with the gateway. It learns the gateway (supposedly) the same way it learns a new opener or code.

What model is it? Do you have a manual? See link. Is that your model?

It doesn’t have a hub or door sensor or anything.

This makes no sense. Dumb question, at one time you were able to operate your door from anywhere using your cell phone? If so there has to be a WIFI hub? Either built in like mine, or remote, as shown in manual.

Yes. But if I look at other models, they say both MyQ and WiFi on the device somewhere. Mine simply says MyQ. Frustrating experience.

It looks like your opener supports MyQ, obviously.  You should have a gateway that is directly plugged into your router somewhere in the house. The earlier MyQ did not use Wifi. It used a gateway that plugs into your router via ethernet  cable and communicates to the opener via 900 MHz signal.  There are other MyQ accessories as well bu the 900 MHz version is obsolete.

Check out the link for gateway manual  that works with your opener. Gateway has to be there somewhere in your house if it worked before.

I also have a wired Liftmaster MyQ gateway.  I will have to take a look at mine when I get home tonight , but if I recall correctly when powered up there is a blue LED in the unit that lights up.  On the network jack you should have two LEDs one solid and one that flashes.

You stated in your original post that you lost the "power cord. found one".  If you are talking about the ac adaptor that powers the unit did you fine the original one?  If not, make sure the adaptor you are using is the same volt, amp capacity, and polarity as the original.

I bought a universal one that I have to adjust the voltage. I can’t find information that tells me what it is when I look up the product. The green light is on, and it is Amber when searching for a new device. But it is not finding my opener, whether I use the learn button on the wired opener or the device itself.

This is accurate. I did have to get a universal power chord and find the appropriate voltage so that it powered on. I completely reset the gateway and now it does not receive the signal when searching for the opener.

Well, I called chamberlain customer service. They said it’s likely a bad gateway and now out of warrantee. Need to buy the updated gateway.
