![]() Running stock firmware, the mac's are correct no matter what the macs in the cfe are. I have found in certain devices, wap54G V3 for instance, the mac's in the cfe do not match the mac on the sticker. Does anyone know if it is safe to install a newer version? While we are talking about this particular router, I should note that I installed v23 SP2 (09/15/06) std per the instructions referenced above. In other words, the DD-WRT install does not involve replacing or modifying the CFE.BIN ? This CFE.BIN file is the original since I have not replaced it and I'll I've done is install DD-WRT per: So, I'm assuming I'll find the matching mac somewhere else.Īnd because I'm a noob, I want to make sure I understand something. That is to say, they didn't match the mac address on the bottom of the router (which is also shown in the DD-WRT GUI). I'm very glad you made this post because I had found those variables and the mac addresses shown made no sense to me whatsoever. Meaning, the sticker on the box, that should be et0. This unit is one of the ones that doesn't care about the et0 and il0 variables.Īs long as you are here, which mac is what? So there is no easy answer to your question.but if you ask.we can probably point you in the right direction.įor the Gv4 unit.the MAC address is actually located at Hex address 1E00 This has a totally separate loction for the MAC address on the flash chip (it isn't in the CFE).and to make matters worse.the extracted data from this unit is Byteswapped Little Endian aning you have to byteswap it first so you can read it.edit it.byteswap it back.then JTAG it back on. That said.another really tricky unit is the Serial Flash CFE of a Netgear WGR614L unit. s just trial and error when finding the correct variable to change. They have a separate location for just the unit's MAC address. Location: Wherever the wind blows- North AmericaĬ are some CFE's that don't use the et0macaddr and il0macaddr variables. Labled et0macaddr=xx:xx:xx:xx:xx:xx, and il0macaddr= bla:bla:bla. I scp'd the cfe after I put V23SP2-std on the router. ![]() You can search for those with many hex editors, or even search for the ASCII NVRAM variable names, like 'et0macaddr'. Depending on the hardware manufacturer, the first three hex pairs of the MAC addresses should be constant. ![]() Use a hex editor (I use frhed) to scroll through the cfe.bin file until you see what appears to be the MAC addresses. Tell us the hardware manufacturer/model, and the CFE version, and we can be more specific in what to look for. I understand the hex editor part but are there any tutorials about how one finds and changes the mac addresses? But I should have posed a better question. ![]() There are plenty of free (freeware) hex editors available.Īnything more than that, you need to compile the source code. All you do do is simple edit/replace of macs using a hex editor. ![]()
