was not able to SFTP to the device using the changed ID/PW
ID (username) is always "root" on DD-WRT for SSH and SFTP (WinSCP). The password is always what you set it to be. Hopefully this bit of info will save you from reverting or reseting the router in the future for firmware upgrades. I'll add a reminder to the install guide.

the router came back with 29264
Seems about right for this router....

I'm now showing 7E for the LAN, 7F and 81 for wireless, so it seems everything is good to go.
Congrats!

Anyway, my thanks again for your help. Hopefully this dialog will help others.
It will. Enjoy your new router! _________________ Ubiquiti EdgeRouter X

Yup, that was the problem. I was using myID/myPW and root/admin, and then root/00000000, then root/12345678, then... then...
I did a 30/30/30 so I have no more my uuid. Can I still change my CFE?
You do not need UUID to install DD-WRT. You do need UUID if you want to go back to stock firmware - since you don't have the UUID, you can not go back. DD-WRT (or ASUS Merlin) is your only option.
Yes, load the CFE. In fact, you should follow the entire guide, skipping only the UUID lines. _________________ Ubiquiti EdgeRouter X

Hello everybody,
I have just bought used EA6400 and flashed it latest ddwrt firmware with success and can log in.
I just want to know If there is any tutorial about simple settings on router for PPPoE - Wireless N+AC - USB Storage - Client and Bridge modes etc...
My problems;
PPPoE setting was made and Mac Cloned of my ISP router (both WAN and wlan) then could log in internet and access but after a while I loose signal of wifi each time. I tried to flash 2 different ddwrt revisions on router but the result was same.
Another weird status is even I change my router MAC and clone it to my ISP's some after time it changed to its default and lost internet connection (on latest ddwrt 29308v) status show wan and wlan id as routers original but in mac clone section it remains my required clone MAC values.
Any comments and suggestions will be so grateful here.
Thanks, UI
Well all above problems were fixed with the ddwrt firmware version 29316.
Even I applied Thermal fix on the router the temprature remains at same level 80-85C. I think this range is acceptable but what is the risk level of heating for this broadcom SoC?
I have a problem I could use some advice on. As stated in an earlier post, I installed via butterworths post and all was great. Tonight, I decided to experiment. I set overclock to 1200, save and applied. Then reboot. It has been non responsive since. Port light on, but computer cant access the router "unidentified network". I have tried dhcp and setting the ip manually. Wifi networks on the router are also not broadcasting. In this position, what can I do?

Why would you experiment like that if you don't have the knowledge to fix the ensuing problems.
You'll need to use serial recovery if you cannot get the cfe mini webserver to come up. _________________ I am far from a guru, I'm barely a novice.

On the previous page, I saw a post about temps and said he was at 1200. I foolishly thought that if his was ok on it, mine should be as well. Oh well, ill either buy a cable or pop it in the trash. Either way, thanks for the reply.

That is perfectly acceptable, and exactly what these packages seem to be designed for. It also means that the heat sink is in contact with the die (you're not seeing 100C+ temps that others have seen, therefore there is contact).
In fact, it's generally not high temperatures by themselves that break electronics packages (die attached via solder to a substrate, which is then attached to a motherboard/circuit board) - it's temperature cycling, i.e., going from hot to cold to hot to cold repeatedly. So just leave your router plugged in all the time, and the temperature won't vary more than 10 deg C or so.
70-90 deg C die temp is just normal for this kind of package.
A side note: if you play around with overclocking your personal computer (not router, which I wouldn't mess with; see posts above), never ever repeatedly "stress test" your machine for short periods of time (i.e., go-stop-go-stop-go-stop, etc). Every time you press "go" on prime95, you heat up your processor to its max. Every test counts as one thermal cycle. Rule 1 on computer processor (again, not router SoC, which is different): stay below 80C. Rule 2: temp cycles kill, not temps alone.
Likewise, every time you unplug your router, let it cool, then plug it back in, that's a temperature cycle. Once it's good and working, just leave it alone and plugged in.
My background: I'm a mechanical engineer doing analysis work for electronics packaging (literally answering this question on various silicon-die/solder/dielectric-substrate systems for a living). I actually know what I'm talking about here, versus just making an educated guess on a topic like how to install DD-WRT. =) _________________ Ubiquiti EdgeRouter X

Well sounds made me comfortable. I just worried about after saw a few posts here some people had seen 20C decrease after thermal fix and seen 60s. maybe they mean at time of first boot up around 40s and reaches 60s in couple of minutes.

My router was reaching 105C when I decided to do the mod (thermal paste, etc). It went to 65C! Later, it kept reaching 90C. Did the router "unmodded" itself? Turns out that there is a HUGE diference in running the router in a hallway at 36C (I'm in Brazil) and a room with A/C at 22C blowing directly on the router.
Also, if I place the router vertically AND sideways, there is another 5-10C drop.

And when you took the heatsink off, there was probably little to no impression or indentation from the die on the heatsink pad, right?

And you probably had it in a cool room at the time?

Maybe, but probably not. It's probably in a warmer location.

Yep. You'll probably see a ~14C rise (because the hallway is ~14C warmer). All component temperatures must be referenced against the room temperature to be really meaningful.

That was my hope - I really think that 80C is fine for this application. Of course, if a cold router was the goal, we could absolutely do better. We could strap fans to the thing, drill holes, strap a coolermaster hyper 212 evo to the thing, but there won't be any additional performance gained for all that work and cost. Better to call it a day and go have a beer instead =)

I wrote about how the 2.4Ghz on this was terrible staying in the single digit last month. Well now I've upgraded to R29193 (03022016) firmware and it appears the performance has gotten better. I'm hitting more double digits than before. It could be a fluke but I like this version.
