    Meh, I wouldn't mess with the antenna built into the EP121. upon further reflection, I wonder if the user's router config has been tested with any other devices for comparison at 300Mbs? might bean issue with the specific channel in use, i.e. interference etc.

    Which router are you using?

    The card looks like it only has 2 connectors, and there are only 2 connections for the EP121. Try swapping the wires and see if it makes a difference.

    Using DLink 2553 5.0GHz AP connected to multiple 5.0GHz devices throughout the house without any problems. Just took it back apart and switched antennas (what a pain as those antenna leads are cut exactly to length!!) No difference - Really doesn't make sense to me...

    One more thing to try.

    Switch your power plan to High Performance or at least Balanced, make sure that Wifi is at full power, in the options. See if that makes a difference.

    Do you get a strong signal, and then it just drops out suddenly? Or no signal at all? Erratic signal?

    Currently set to Balanced (that's where it's at by default - is anyone running 'Power Saver'?) tried High Performance. Wifi shows full strength... and it will connect and some pages will load eventually... most won't. As soon as I disconnect and then reconnect on my 802.11g access point I'm good to go. Signal strength is steady no fluctuations.

    Again, my other two laptops (Alienware m17xR2 w/ Intel 6300 * Alienware m11x w/ last gen Intel card) connect w/ no issues. The m11 does just have two antenna leads like the EP121. The DAP-2553 is a great device.

    I have had my 6230 installed and working fine for over a month now.
    I use a dual band router and have it set for 5 MHz - my performance is very good. Likelt twice what it was with the Anthros single band card.

    Thanks for the update, Loren.

    The current Anthros card appears to max out at about 8.50 MB/second when copying files from a relatively fast network server's SSD drive through a D-Link DIR-655 802.11n (not 5GHz) router within about 10 feet of the EP121, which apparently isn't quite enough bandwidth to stream 1080p HD video.

    Can you give me an idea of the transfer rate you are achieving when, for example, copying a file from a fast machine across the LAN->wifi link?

    Hmm, So I guess I would have to replace the card and the router too? If so this may have to wait a while.
