@Kevin_Z It looks like everything is ok here with the beta firmware. Now I'll wait for the official firmware to update the other mesh routers. Is there any estimate of how long this might take?...

@zexoni70 can you please send me this beta? my e-mail is: marco.aow@gmail.com

same problem here i tried different browsers and computers i also reboot the router the problem still persists it seems like something so simple to be checked within the TP Link test lab before...
