August deadbolt alternative

For the last year and a half I’ve had an August deadbolt working in HA. As of a few months ago the wifi connection in it has become worse and worse, despite not changing my wifi in the house. It will stay connected about 4 hours a day, 6 if you’re lucky. I’ve tried everything - new batteries even though they report fine, different SSID, different wifi power settings on the WAP, different channels, locking the lock to a single AP. Nothing works. The lock is literally 4 feet from the closest wap, and the doorbell next to that door stays connected 100% of the time.

Are there other brands out there that will give me a better experience? I now also have z-wave in the house so it could be a z-wave compatible device as well. My last house I had a Schlage smart lock with keypad but it died at 13 months as well. I’m starting to think these things are meant to be replaced more often than smartwatches.
