very good modem . increase speed between isp and my network by 50 % without change anythng . old modem provide by isp be a dog . one thing though , initially could not complete connection transaction with my isp -lrb- Comcast -rrb- through they `` wall garden '' web page . the modem issue `` power failure '' status . set the modem back to `` factory default '' , which it should have have right out of the box but , apparently , do not and do a soft reset clear up the problem . it immediately connect with my isp and have be work well ever since . do not get very warm and I no longer experience connectivity drop out like I do with the isp supply modem . I should have do this a long time ago . highly recommend .
