Question about D-Link Xtreme N DIR-655 Wireless Router

2 Answers

DIR-655 wireless intermittment - connections drop -

I just purchased and installed the DIR-655. The direct connection links are up, running and working well. The issue we're having is with two different laptops that are 'b/g' wireless capable. We will see the router from time to time and sometimes are able to connect, however the link will not stay up nor are we able to see the router continuously. It does not matter how far or close we are from the router. I have tried secure and unsecure modes and have upgraded to the latest version of the firmware (1.07 Dec 08). Is this a HW defect or is there something else going on????

Thanks

    Same here.. I've had the same problems with hardware rev. A2 and A3

  • Anonymous Apr 08, 2009

    DIR-655 hardware A3 firmware 1.21,

    Wireless with WPA2-PSK/AES in g/n mode,

    Wireless client connection keeps dropping and reconnecting,

    DIR-655 logs "Wireless restart" coinciding with client drop,

    No other interesting log entries or wired interruptions during these events,

    Wireless survey shows no other nearby AP's on neighboring channels.

  • Anonymous Apr 15, 2009

    Same here.. I've had this with rev A1, A2 and A3.

  • dwitteried Apr 27, 2009

    I get the same problem with the wireless connecton dropping. The reciever is about 18 feet away with two interior walls between it and the DIR-655. Signal strength at the reciever is 100%. Walls are perpendicular to the two devices so the signal should be good.

    From broadbandreports forum:

    Please try following the guidelines below :

    a. Ensure that the antenna of the router/access
    point is positioned for best reception. You would
    need to determine the best orientation for the
    antenna in an ad-hoc manner by trying out the
    different possibilities yourself. Take care to keep
    the product away (at least 3-6 feet) from
    electrical devices that generate RF noise, like
    microwaves, Monitors, electric motors, UPS units, etc.

    If you are using 2.4GHz cordless phones or X-10
    (wireless products such as ceiling fans, lights,
    and home security systems), your wireless
    connection will degrade dramatically or drop completely.
    Anything using the 2.4Ghz frequency will
    interfere with your wireless network,

    b. Try changing the WIRELESS CHANNEL of operation
    on the router/access point. Experiment with
    different channels till you find one which presents
    you with minimal interference,

    Please refer the link given below to change the
    channel on the router:

    »www.support.dlink.com/faq/view.a···=channel

    c. Set the PREAMBLE to SHORT on both the card as
    well as on the wireless router (under ADVANCED >
    PERFORMANCE for the router),

    Please refer the link given below to change the
    preamble to short on the router:

    »www.support.dlink.com/faq/view.a···preamble

    d. Try locking up (lowering) the speed on the
    wireless router and on the wireless card as well.
    Try different speeds till you get one that gives
    you reasonably good speed as well as a consistently
    good connection,

    e. Finally, move the router closer. Try getting
    the router and the wireless PC into direct
    line-of-sight though you might have physical obstacles
    in between,

    In case you are using WEP, DISABLE the same if it
    is not absolutely necessary, because WEP as such
    involves a lot of added overhead.

    These should bring about considerable improvement
    in the quality of your wireless link.

    I did as they suggested. And it's working now. I'm glad I don't have to but a new router.

Any one with a mac ... MAKE SURE "Enable Auto Channel Scan : " is OFF.

CHANGE the name of the WIFI Network.

SET the Channel to CH11 [Others interfere with phone signals]

SET Security to WPA, TKIP Cypher, 3600. Then enter your password [min 8 all lowercase chrs] Change it when you are working.

Save and unplug the router and you will be fine.

I have DIR-655 myself and my Firmware version is 1.21 which is the latest. So 1.07 cannot be latest

Posted on Feb 09, 2009

  • partizan Feb 10, 2009

    Sorry, it seems that you have posted clarification about 1.21 at the same time I posted my clarification. This signal drop is not normal. If you purchased at a store where you can easily return or exchange, I'd do it. Otherwise, call D-LINK techsupport.

    By the way, does the router have enough air flow from the top holes? Is it very hot to the touch? It might be just overheating... Just a thought
