I buy the item from SSDEALS , receive in about a week time . set it up and call my isp to have it activate with they . while on the phone , this modem crash the entire node because it be `` flap '' several time a min . -lrb- request a IP then go offline imeditatly and cause a DOS in the node -rrb- I take it offline and have to set a static IP on my computer to even access the webguus -lrb- it would not even establish a dhcp on the Ethernet side either ! -rrb- accord to the log it be give a tftp error . configuration file NOT FOUND . so I send it back for a refund . since Staples be sell it for the same price , I just go to they and it work right out of the box and all I have to do be give my isp the MAC address and it be up and run before I get off the phone with they . apparently these be not test before they be send out .
