Doorbell keeps going offline even after resetting. Any suggestions?

If you bring it indoors for testing does that help?

If the doorbell is connected to your home wifi, try measuring the wifi speed by putting your phone as close to the doorbell location as possible.

Use the free Ookla speedtest app, and make sure that mobile data is turned off during the test. Pay particular attention to the upload speed.

My defective Craftsman garage door opener interferes with my Arlo for 6 months.

Can you provide more information?

After 6 months without a solution, almost gave up, I just found out my defective Craftsman garage opener has been interfering with the camera. After removing the garage opener battery, no more issue with my Arlo camera. The new updated software that I had been concerning is perfectly fine.

Craftsman garage opener was Sear’s product. Sear closed. Chamberlain now owns this line of product that I just purchased it’s keypad from my local Home Depot. My ~20 years old garage opener is operating at 315MHz for keypad opener. Perhaps Arlo used this operating frequency after Sear had sold Craftsman line of product to Chamberlain, which has been causing interference. Chamberlain names it as a universal garage keypad opener. When I come home and open my garage door, both the opener keypad and nearby Arlo camera transmitter at the same time, simultaneous transmissions at the same frequency interferes with each other. After using the Crattsman keypad for about 10 years, the keypad recently acting weard, perhaps it has been transmitting to synchronize with my garage opener to interfere with my Arlo 24/7 for the last 6 months. Hoping this sharing post can help out all the Arlo users with the same offline issue. I enjoyed using Arlo for 10 years, only extremely disappointed from these 6 months without a solution. Arlo is a great product, if no wireless RF interference with Craftsman garage opener security pad.

Perhaps, new Arlo software recently pushed our cameras to use 315MHz, garage opener wireless operating frequency, because I never experienced this RF interference from the last 10 years using Arlo cameras.

The keypad cannot be shielded because it needs to communicate with the garage opener. If it has front end RLC band pass filter, it’s 20% at 3dB bandwidth would be 283.5MHz - 346.5MHz given that the center frequency is 315MHz, any spurious RF noise near 2.4GHz shouldn’t leak. Noise could leak if no front end RF filter has been implemented. Most electronic device operating at 2.4GHz also has its monitoring signal at either 315MHz or 433MHz controlling the status of the device. Not certain whether Arlo actively utilizing this side band frequency of 315MHz to control and monitor its camera status and providing status notifications as improvements proceeding with the recent firmware release that could mess up all of our camera with RF interference. I am not certain with the root cause of the interference unless being tested, but both of my Arlo pro and Arlo pro4 are working perfectly fine now for a day after replacing my Craftsman garage opener keypad.

If anyone needs to replace Craftsman garage opener, $41 at Home Depot, $21 from Amazon. The one before me showed the cashier the $21 from Amazon for price matching. The cashier also helped me to show her the $21 from Amazon for price matching….:-)

How interesting. I am glad to hear that they are working as expected now. This is helpful information for users in the community and I appreciate you sharing it. If you have any further questions, please reach back out to the community and we all would be more than happy to help. Have a great rest of your week.

After replacing the keypad, the new keypad still interferes with my nearby Arlo because it still communicates with my Craftsman garage opener, however only when I use it to open my garage at the same time that my Arlo is recording my motion at my garage door, not as bad as the damaged keypad interfering with my Arlo 24/7. To have a total wireless interference free at 315MHz, I just replace my garage opener with the Chamberlain one, costs me $180 from Home Depot. Chamberlain garage opener uses Security 2.0, I don’t know what wireless frequency but it is not interfering with my nearby Arlo watching my cars at my driveway. Unless Arlo reprograms their firmware to update their software defined radio (SDR) with the monitor & control frequency from 315MHz to something else, if we wish to continue using Arlo as our security cameras we have to replace our Craftsman (315MHz and 390MHz) garage opener to Chamberlain (Security 2.0).

Doesn’t help. Security 2.0 selectively switches its frequency between (310MHz, 315MHz, 390MHz) with the strongest signal. Just after replacement my Arlo was working fine for a while in the afternoon, offline again in the evening perhaps when the garage opener switched its frequency to 315MHz. It is an issue when it detects the strongest transmit 315MHz from the Arlo and locks onto it. Have to return the new garage opener.

Arlo has to fix this issue ASAP. It becomes our security issues because the thieves would jam our Arlo security cameras with their radio gun tuned to 315MHz to set all of our Arlo cameras to offline before they steal our properties and/or entering our homes.

Best not to double post. FWIW, I replied here:
