I have a DIR-655 with Hardware Version: A4 and Firmware Version: 1.34EU (DIR655A4_FW134EUb07Beta).
However I am having serious problems.
My download speeds are limited to 2.3 MB/s (goes up and down), however I should reach approx. 14.5 MB/s (big difference).
The weird thing is, when I flash the router to a different firmware (already tried DIR655A4_FW131EUB02 & DIR655A4_FW134EUb07Beta), it works without problems and downloads at 14.5 MB/s in the newsgroups. However as soon as I save something in the router and reboot then my speeds drop again to 2.3 MB/s.
I already checked various settings including my firewall settings, disabled wireless completely, changed to OpenDNS servers, disabled / enabled advanced DNS settings, etc. etc. etc. It doesn't matter it stays stuck at 2.3 MB/s, unless I flash the router again. Then it works once again at 14.5 MB/s, until I save something again in my router. And I do need to save, cause otherwise my router is unprotected. :S
Funny thing is, my older router, which I have here also is a DIR-635 and that works without problems, however due to 100 mbit WAN port, my speeds are limited to 12.5 MB/s instead of 14.5 MB/s. Yeah I know, only 2 MB/s difference. But still I thought the DIR-655 would be a better match, then the DIR-635.
Anyone knows what is causing this? I am really getting fedup with my DIR-655. And because of all this crap, I am thinking about stopping to use D-Link stuff permantly!
