Hi all,
I’ve been experimenting with Home Assistant (HA) and loving its possibilities so far. I’m eager to expand my smart home and explore automations. However, I’ve encountered an annoying issue: after some uptime, usually a few hours, HA becomes unreachable as it loses the wifi connection. When this happens, I can see in my router that the HA device is no longer connected.
I am running HA OS on a Lenovo Thinkpad 14-IIL 20SL with an Intel i5 (1035 G4) and an Intel AX201 wifi card.
Here’s what I’ve tried to resolve the issue:
- Set a static IP in both HA and my router
- Disabled IPv6
- Manually configured DNS (Google and Cloudflare)
- Created a separate Wi-Fi network for HA (tested both 2.4 GHz and 5 GHz)
When the connection drops, I can restore it by restarting the host or using the command line on the host (via nmcli).
There are some entries in the host logs that I believe might be relevant. Please see these below.
I note that in addition to this issue, HA is also frequently showing the ‘Connection lost, reconnecting’ message when the system is up. I think this might be related.
I would greatly appreciate any advice or troubleshooting tips to help resolve this issue, thanks in advance!
