Netgear WGR 614 V6

  • For the Lay(wo)man: This "thing" is a wireless device, something that you need to connect devices (computers/phones/etc) wirelessly to each other. It was continuously re-booting. So the info below explains how this was set right and what the problem was.
  • Netgear WGR614 V6: Wireless 54 Mbps router borrowed from a friend.
  • Symptom: keeps rebooting after a few seconds. Traffic dump shows the Router expects to be given the vxworks image. But after it fails, resets again.
  • From the netgear forum found that it could be an issue with the MTU (there is a need to decrease) it.
  • Also disabled uPnP.
  • This did not help.
  • Finally changed the power supply and the Router is holding.
  • The Spec of this Router is the following: Processor/chipset: BCM5352 SoC, 1MB Flash, 16MB RAM. Currently, Linux will not run on it cos the images are bigger than 1MB. The Flash needs to be upgraded to atleast 2M before any small WRT image will run on it (dd-WRT). Jtag pins are not exposed so they cant be used. The visible connector inside the box is the Serial port which runs at TTL levels.
  • Also have to report the use of a "telnetenable" windows executable, which creates a proprietary packet and sends to the Netgear router and after this lets one log in and check random things using telnet.
