Īlso my wireless keys contain 8 letters, but I think the full alphabet is used for the random generation.Īdditionally to yours above, mine contain:Ī,B,C,F,G,H,N,T,Q (taken both from 2.(Last Updated: August 07, 2021) | Reading Time: 3 minutes If Technicolor really refused to give you the source this is a clear GPL violation and you should point it out to the FSF. Replug everything like it was, power cycle.Īpart from that: What you said about the sources being unavailable to endusers is very interesting. Login and click wireless, disable wireless, saveĤ. Do a factory reset (Plug power, and push 40 seconds the reset button)ģ. Remove the power AND the coax from the modemĢ. I ran into the same problem - there is a trick to fix it:ġ.

If the wifi password is truely "random", the password is still only 8 digits only uppercase letters from which only E S P K M R X Z were observed so far (only 8!). internet was ordered WITHOUT wifi, because they want extra money for it!). can access my wireless network which I never activated (btw.

well most propably just the MAC address or something other visible from the outside. It is not possible to edit the dumped config file and write it back, because this is broken in current software.ĭe facto, anyone who figures out the algorithm that calcs the wifi password based on.

There is no way to disable wireless (or edit the password) because I am greeted with the error message The connection to the server was reset while the page was loading.

If it is possible to address 128megabytes after 0x80000000 the real physical memory is mapped to these addresses.įrom linux bootlog: Serial: BCM63XX driver $Revision: 1.4 $ Next steps are to check the available address space (too high addresses crash the unit). As this takes ages to dump megabytes of data over uart, here is just the stirngs command on the first few dumped kilobytes after 0x80000000 to prove that it is at least possible to get some useful data out of this: strings are used by the bootloader for the flash partition overview table printed on startup). power up the device, reset it and then dump the RAM contents.

Fortunately the boot images seem to get loaded into this address space during bootup which may make the system cold-boot-attackable. It is not possible to dump the flash content by the bootloader as the memory dump function only handles addresses 0x80000000 and up.

The linux login does not work (admin/admin), as the session terminates immediately after login. There is one SPI flash of 1megabyte, one parallel nand flash chip and one DDR ram chip. One UART interface provides bootloader access, the other one linux /dev/ttyS0. Finally I've got a unit the cable provider does not want back, so it is time to open it up and check for the two UART interfaces.
