Is it me or is Orbi's guest wifi not reliable as non-guest wifi?

I seem to have non-working network connection issues (shows connected though) with it in my RBK753S-100NAS with the latest firmware since I got it late last year. I have to disable the wifi and re-enable to get back on. Renewing IP address doesn't always work too.

Thank you for reading and hopefully answering soon. :)
