    Every day I need to restart the eircom modem to get 24 meg speed or else it drops to 8mb. Can live with it but annoying. Any ideas?

    This used to happen to me when I ws with Eircom on upto 24MB. My normal speed was 13MB but after 24 hours I'd only get abou 7MB until such a time as I rebooted the router.
    In the end I got one of those timer plugs and programmed it to poerw off at
    2am and power on at 2:05am. I had my top speed consistantly then as it never passed 24hrs without a power cycle, it's a pain I know but numerous calls to Eircom couldn't fix it and I had the timer lying around anyway.

    unless you live inside an eircom exchange it is very very unlikely that you can get a stable 24meg connection

    line attenuation = distance from your router to the exchange

    example: 40/20 = you are quite far from the exchange
    20/20 = you are close to the exchange

    signal noise margin = how much interference your line gets

    the lower the number the worse your line is

    example: 6.0/18.0db = bad the best you can hope for is 8mb stable
    15.0/18.0db = ok the best you can hope for is 12mb stable
    30.0/18.0db = good but you will still only hope for 16mb stable
    40.0/18.0db = excellent but still best stable speeds will be 20mb

    when u combine a high line attenuation with a poor signal noise margin you get crap speeds because there is too much interference on your line at higher speeds so if your router keeps dropping to 8mb then it's likely that it cannot get a stable connection at any higher speeds.

    the router is set to always connect at the best obtainable speed that is stable.

    there is a few minor things that can improve the signal noise margin a little bit.

    1. high quality dsl filters - these can clean up the interference a bit and boost stability

    2. reducing the number of phones/skyboxes connected to the phoneline (skyboxes are hoors for adding noise on a phoneline unless you use on demand services you dont actually need them plugged into your line)

    3. minimising the use of phoneline extension cables... these are generally unshielded and thus allow interference on your lines.

    Exchange is 2 mins walk from the house. Comes in at 18 megs on a speed test and generally get 2 megs dowload speed when router is restarted. After a day it goes back to 9 meg on speed test and around 850kb downoad speed
