Hello everyone,
Since I started testing the OpenWrt 25.12 beta builds, I've been experiencing Wi-Fi issues. So far, I've only noticed the problem on Samsung devices.
If a Samsung phone stays idle for some time, it loses internet connectivity even though it remains connected to the Wi-Fi network. The only workaround is to manually disconnect and reconnect to Wi-Fi.
I'm currently running build 25.12.04 and the issue is still present. It's very frustrating because it happens multiple times a day.
My router is a D-Link DIR-878 A1.
Has anyone else experienced something similar with Samsung devices on the 25.12 beta builds?
Thanks.
Then don't use beta (snapshot ?) builds, they're called betas for a reason ... ?
I didn't say I'm currently using a beta version. I said I've been experiencing this issue since the beta builds.
