    Hello :)

    I have recently discover your website. As i am experiencing problems with my wag54g i was thinking about changing the firmware to a 1.02.5 but wich one to choose ? AnnexA or AnnexB ?
    Whats the difference ?

    Moreover my main problem is that everyday, i have to switch off and on my wag54g in order to get back my wifi signals and adsl connection.
    It s strange because none of the leds indicates problems, but no way to solve this unless to switch off and on
    any idea ?
    i will be really gratefull if anyone is able to help me

    (sorry for my english, i try my best !)
    Yours sincerly

    Thnks for such a quick reply.
    So i need an AnnexA i suppose :) (as i don t know what isdn means :))
    I also have noticied that this wag54g is different from my other wag54g. The back is a little different, as the connexion for lan wires rj45 avec surrounded by a yellow mark on the new one (wich does not work perfectly) is it important ? has this a meanning ?

    But i am not sure this will get my wag54g working; cause i don t really understand why i would have to switch off and on each days !? quite strange no ?

    ISDN = Integrated Service Digital Network

    its the Phone standard in europe, especially germany... and
    AnnexB is for ADSL over ISDN ... only needed in europe..

    in usa u need AnnexA.. an AnnexB device wouldnt work in usa...

    Ok thks !

    But let me expose you my situation. I have 2 wag54g. One for home, one for my office.
    I have one notebook on wifi .g for connecting to those. I have configured the two wag54g exactly the same : wifi g; lan 200.0.0.x; WEP encryption 64bits; MAC exclusively in wifi for my notebook.

    The problem come for the wag54g at my office : no way to get a real wifi connection.
    I have changed the modem twice, i have change of location, i have put my notebook close to the antenna. No way to get my wifi connection stable :
    always swapping on the status windows of win xp from 1mbps to 54mbps with no reason. I suffer of disconnection every minutes. The hell of this modem and i have no real solution.
    Is it a problem of firmware ? (at home 1.01.7; at office : 1.02.3)

    in your situtation i would use the firmware which is stable (your homes firm) at both locations... no matter if it is the older one.. if it meets your expectations its the one for you ;-)

    btw, when flashing dont forget to reboot the device, then flash, then factory defaults, then use ur settings you need..

    hope that helps..

    ISDN is not the phone standard but a digital service which makes it possible to get four or more telephone numbers. It's digital indeed. You need special telphonesets or a small home exchange. POTS (normal analogue telephone lines) are the standards in Germany, Holland, Belgium and many other European countries and ISDN is an option over the normal analogue lines. The speed is 64k on one ISDN channel or combined 128k if you use both ISDN channels.

    My believe is that the hardware of the WAG's is different because of the different specs of the bandwidth on the lines when ADSL is used on ISDN or on Analogue (POTS) line.
