Anyone else seen this.

Indeed - there is a guy (still) selling complete Topfield PSU reburb kits...

" The Draytek self-reboot is well documented. PSU degradation or firmware bit rot seems the most common cause "

Firmware bit rot not mentioned in that link, which is hardly 'well documented'. It's just 'how to get more information if your router seems to reboot.

Strange to delete the second part of your quoted text...

That wasn't the only place - people talked on forums. I went googling. Found a lot of hits. Didn't know I needed to write them all down because you would attack my integrity.

Why are you trying to make me out as a liar? What would be the point of that?

More or less any consumer grade switch mode power supply! The Draytek in question was a, can't remember the blinking number but was a rack mounted jobby.

Had a TV the other day the caps after the rectifier where shot oddly enough read fine on a PEEK Cap tester but a couple of new 105 deg ones sorted that.

And for that matter any test gear of a certain age, power supply caps change them they don't last forever!..

Yes they have over time been good, mate of mine who's a Cisco freak reckons they're not bad!..

Mine has a wall wart. Don't think its a switched mode johnny.

Indeed. I had a valve radio from the 1950s that needed a new cap on the main HT supply.

I still have a CISCO SOHO router. but it was a re badged unit from IIRC Linksys

Got fearfully hot , Never missed a beat though
