    Hi everyone. I noticed that I get the exact same performance with a 150 megabit wireless adapter as with a 300 megabit one (10-12 MB/s). I was wondering why that was. I'm running N only, wpa2 personal aes encryption, 40 mhz on 2.4ghz ( I know that's not ideal), manual wlan interference mitigation, with frame burst enabled, apsd disabled. Does the firmware or any of these features have a 100 megabit wireless bottleneck? Or is 300 megabit not fully supported for this device? The device list does correctly list tx/rx as 300/300, 150/150 respectively.

    There's not enough info to answer your question.

    What type of traffic? A file transfer between two devices in your LAN? A USB drive in the router?

    Do you get better performance from a wired connection with the same file transfer? Did you compare performance with 20MHz channel width, interference mitigation disabled, everything except possibly frame burst set to default?

    It's between 2 windows computers, one connected via gigabit ethernet, and the other being the 150/300 megabit wireless adapter, using the windows to do the transfer by having the folders be shared. Tested a 500MB compressed video file and judged speed based on the reported copy rate.

    Using 20 mhz does seem to almost halve the transfer rate to 5 megabyte/s. The effect of other settings are hard to determine against natural variation. I'm happy with the 150 megabit adapter performance. I'm mostly wonder why the 300 megabit wasn't any faster.
