FCH1967 Can you describe these “micro-interruptions” in more detail please? Since when do they occur? Is it the DSL link that sometimes goes offline briefly? This would be recognisable by the fact that the LED on the Internet box turns red. Or are packet losses occurring? You can determine this using the ping command, for example. The connection values as requested by WalterB are also of interest.
Have you tried turning it off and on again?
