Iam using a D-Link DIR882 and had some problems with the Wifi on the last linked release on the homepage with Version 37305, so i flashed this version here.
After flashing the build 04-25-2019-r39654, the router was in an endless loop of restarts, the LAN came up half a minute, but no wifi, then it restartet itself.
I also tried it with a reset to default settings, but it was the same result.
A factory to dd-wrt in recovery mode worked back to version 37305.
After a complete recovery and flashing back to the 04-25-2019-r39654 via webinterface from the 37305 the router was able to start.
Then on 04-25-2019-r39654 i tried to connect with some wireless devices and tried some settings. Also with no Security and G-only i wasn´t able to connect with a single device.
