All electronics generate heat. Even if VHF-RF devices are particularly
lossy (which I question as a general principle), the amount of it in a
router is minimal - milliwatts - so not that relevant here. (And it's well
above VHF, too: 2.4 GHz mostly, some 5 GHz in some recent devices.)

will have adequate venting 'cause they were designed with that in mind.

How very trusting! (Plus, also, even if it happens to be true in a
particular case, users have a habit of using things in ways they weren't
designed: in hotter than specified temperatures, on their side, with
inadequate ventilation [such as resting on a carpet], ...) I've certainly
encountered equipment running hot enough that I'd be unsure of its
long-term reliability.

As long as the device (such as a Cable Modem or Cable Modem+Router) has
adequeate ventilation (grills not blocked) and space around it is

We're in agreement that those are good ...

sufficient, there is absolutely no reason to supplement its cooling with
a fan. Whiles the implementation of supplemental cooling is not
detrimental, it is indicative of faulty logic in dealing with perceived
computing issues.

While I agree that I wouldn't immediately blame a piece of kit that had
apparently been running hot for a while _before_ the problem occurred, I
wouldn't rule it out either.

Such heat that such RF devices generate will NOT affect an attached
computer's Windows Sockets, TCP/IP stack or data communications. You

It _could_ if all of those communications are going via the device that is
running hot.

Only in the aspect of more or less of work or not work but not partially
work.




are not even in the ballfield and I am again back to a declaration of

PEBCAK. In fact I will now go further and state computer based
Munchausen Syndrome is evident.

You are smug. (I realise I am being a bit, too, in response.) While I tend
to agree with you that the hot device is probably not the cause, I would
not make such absolute statements - and I'd try to find a kinder way to
say so as well.

This is Usenet and I am not related therefore I can be blunt and not beat
around the bush.

However... I will consider your feedback as a valued POV.
