Hey guys,

Sorry to make another one of these topics, but I've done my reading and searching, and am still coming up dry.

First, I'll explain the setup:

DIR-655, set to N only (for testing, ultimately would like N+G), WPA2 with an AES cypher, channel width to 20/40 auto. It is hardware revision A2, running the latest firmware (1.34NA)

The host connecting is a 2008 Mac Book Pro (which does have wireless N support). I have tried this at all ranges (signal strength varying from 98% - 80%), with no increase or decrease in speed.

I am testing connection by transferring files from my Mac Book Pro to a home media server which is connected the router via gigabyte LAN. Transfer speeds are around 2.8Mb/s (yes Mb, not MB). I can get the same speeds running a test speedtest.net (2.8Mb/s), while doing so on the wired host shows 30Mb/s. This seems painfully slow. If both are wired, it transfers move at hundreds of Mb/s (suggesting that hard drive IO is the bottleneck, as opposed to the connection, unlike this situation)

Worth noting is that OS X reports the link speed at 140Mb/s instead of the 300Mb/s that you would expect to see. Also, both the router and computer report no send or receive errors, and no collisions.

I am probably missing something obvious, but I have run out of ideas on my end. Any possible help would be greatly appreciated.

Thanks!

Several different issues mixed up:

1. Some Intel and Atheros wireless chipsets only provide 150 Mbit
2. Throughput: Have you tried disabling encryption (WPA2) to see if speed goes up? If so, you know the issue with your Mac

1. Is that with this router, or in general? It would seem odd that something would claim to be draft-n compliant and then only capable of half of the throughput available to it.

2. I will try disabling WPA2, but I don't think that accounts for 2.8Mb/s of slowness. That'd just seem absurd.

Any other ideas?

If you want a complete solution to wireless problems, use either firmware 1.11, or 1.21 if u need the usb on the router. Don't bother with anything else... That would be my advice... For ppl concerned with the wireless, firmware 1.11 is the best, you'll notice the increased signal strengh and stability. By the way it is possible to revert back to older firmware, by using the eurpoean russian firmware version 1.31. Worked on mine....

In general, there are plenty of N cards that only provide 150 Mbit, since tjhe N specs are 'layered'.

Absurd maybe, but solving issues depends mostly on elimination
