Router losing connection, DNS errors

[stebbit]

I have problems which might be related:
1. My router loses its internet connection several times every day, the red light flashes and it reconnects after a couple of minutes.
2. The router log has over 600 pages of "DNS name resolution failure" errors.
3. My download speed (Fibre 65) is usually only about 55 Mbps.

The router is a Wi-fi Hub (Sagemcom Fast 5364-3), the firmware version is SG4K10002816t.

It is possible that new firmware version SG4K100130 will fix one or all of the problems.  How do I arrange the firmware update?
