[H] Router and ipconfig /flushdns

[Thane Sherrington]

I had a customer who has a linksys router who lost his connection (worked 
when connected to the modem, but not through the router.)

I suggested he reset the router to factory defaults (using the button in 
the back) and try it.  That worked for a bit, but then it stopped.

He called his ISP, and they had him use ipconfig /flushdns - he says that 
fixed the problem.

How would flushdns fix a problem with the router that didn't exist with the 
modem?  I would think if it works with the modem, then the problem would 
have to be in the router.
