Here is my experience:
I use ADSL
ADSL ends in an ISP supplied router/modem
There I connect my DIR-655
To the DIR-655 I connect D-Link powerline DHP-306AV (and DHP-W306AV remote)
Everything works perfectly for about 10-20 Minutes - then the Internet feed stops. I can only get it back after the DHP-W306AV cools down, and then use it for another 10 minutes.
I had the powerline sets already replaced twice, problem remains.
Then I connected the DHP-306AV to the ISPs router/modem (has 4 sockets but no wifi)
Same, after about 15 minutes Internet feed stops, however, when I switch DHP-W306AV off for a minute, and then on again the net feed is up again - and it stays up with no problem!
Seems that DIR-655 and DHP-306AV simply can't work together, at leat not for me.
Is there any logical explanation for that?
I have no logical explanation for that.
