DSM 750 Poor 11.N Performance
« on: January 01, 2009, 10:11:18 PM »
I have a DLink DIR 655 router (firmware 1.21) set to 11.n only mode and 40 MHz with Security Mode-None (all advanced setting as per factory defaults).

Connected to the router through a 100 MB ethernet link is my computer.
The only wireless client is a Dlink DSM-750 (firmware 1.02).  (router reports 300 MB connection and 100% signal)

When I play 720P movies over the wireless 300 MB link, during quickly changing screens the 750 often stutters, losses sync and losses sound.

The same scenes play perfectly when connected using a 100 MB ethernet NIC on the same computer.

The network utilization (reported by task manager on my computer) of the ethernet link peaks at ~15%.  The wireless peaks at ~10%.

So my question is why does the 100 Mbyte ethernet link outperform the 300 Mbyte wireless link?
Is their extra overhead within the DSM-750 for wireless?
Is this normal behaviour of wireless vs wired?
Are their any advanced settings which would allow the 300MB wireless link to work better?
Potential firmware improvements?

I bought this router specifically to drive the Dsm 750 wirelessly.

Thanks

I've spent many, many hours testing this sort of thing. Mine still doesn't work, but I think I can help with yours. Try 11.n 20mhz.

count me in as a long long tester, i already spend over four days and already return three router dual and non dual bands, tried tons of different options. My old linksys WRT54GS works better with the dsm750 then any of DIR-855, 825, 655 and the new linksys 610N which is a total joke by the way.

this is the first time i tried N wireless standard and i am amazed how bad it performs. i wanted to upgrade from my current G only because of the dsm750, but i guess i will have stretch those wires...

@ djloewen
i will try the 20mhz channel though, as the last chance
