Our ATT 2Wire has been hit by lightening a few times and that's not the box's fault but after the 90 warrantee expires, ATT will replace it for call fee plus box, which is way more than you could buy another one for...
Next time I may try to buy my own replacement and see if I can get it to be recognized by ATT.
Have surge suppressors on phone line and power supplies now, hoping that will reduce the rate of failure (on #4 now). Thunderstorms all summer this year, tired of pulling cords out of the wall every day.
First wireless router (pre-ATT) was a motorola with card from RadioShack, worked just fine too. They all come with installation instructions.
