I just found out that my tablo device got latest firmware 2.2.26. There seems to be a few issues with the device losing IP. Switched from DHCP to fix IP (through ASUS router); seems to "temporarily fix the problem.
However, I also discovered that the place to manually check/update a latest firmware (mentioned as under Settings->About) can no longer be found. Is this a new method of operation (modus operandi)? I am using Chrome from Win 10 PC.
