Browser Access via WLAN - few problems

Hi, I’m using one T-Beam (firmware 2.0.0.18ab874) with WLAN enabled and connected to my local network. Intention is, that I can access the device via Chrome browser and http://meshtastic.local/

It works for few hours, but it seems that WLAN connection is lost after some time. The device itself is still turned on and receives messages.

When turning off and on the device, WLAN connection is reestablished and I can access the device with the browser again, but there is no message history.

So I’m looking for two solutions:

  1. How to keep WLAN turned on permanently
  2. How to keep old messages in browser interface when device is disconnected and reconnected.

Thanks, Christian
