HWClient O Cisco 800 Series

hi

i have registered but they tell me that I am a guest (thu I have
registered - how wierd !)
i m concerned by this topic because i just baught a cisco 857 router &
i had a problem from the first minute i opened the box, it won't
synchronize with adsl, it keeps telling me to check the cable. have
any one of you had this problem & if so how did he solve it ?
