hi guys i have a e3000 i tried to upgrade it with the brainslayer 3.x kernal firmware and when i did i discovered that not only was 5ghz band missing but it was replaced with a second 2.4ghz band can someone tell me why
and my settings from the 2.6 kernal werent rolled over to the 3.x however it was still saved when i rolled it back to the previous stable build
the firmware i downloaded was: dd-wrt.v24-22118_NEWD-2_K3.x_mega-e3000.bin

You can't roll back from K3 without haveing messed up settings, the reason for this is because K3 will upgrade nvram space from 32k/60k to 64k for every supported unit.
Therefore switching from K26 to K3 and back usually requires a hard reset in order to clean and init nvram vars. What you can do is, create a backup of you K26 settings, then upgrade to K3 and if you downgrade again, clear nvram and then restore your previously saved settings. _________________ KONG PB's: http://www.desipro.de/ddwrt/

sounds an awful lot like what my Asus RT-AC56U has. it must be a kernel problem then. _________________ Hi

Has anything happened on this issue? It appears 22118 on the E3000 seems to mis-recognized it as a WRT54G/L. In the process it doesn't see the radios properly. It also doesn't see the wired ethernet ports properly, as the MAC gets set to 00:00:00:00:00:02
Me, I'm just after using an E3000 with a Verizon UML290 4G cellular data USB dongle. I really don't need much else on the router, so a 'less than mega' build would be great.
E3000 has originally 32KB nvram, the K3.x builds will create a 64KB nvram separated from your old 32KB and your old 32KB nvram will be copied over to the new 64KB nvram.

can you fix this by using the
nvram set et0macaddr=your mac address
in Startup under administration/commands/
it;s something we had to do on the Asus RT-N16 as well when moving to the 3.x Kernel build. _________________ Please state what make and model router plus the build number and type of DD-WRT you are using.

Right, so that might work for the MAC, but what about the mis-recognition of it as a WRT54G and the resulting radio issues?
My goal remains, just use this as a dual-channel gateway router with a USB cell modem as the WAN connection. Everything else is really cool and I love the features, I just don't need everything else for this particular situation.
I'd gladly use any build that would get me to having it do what I'm after. 22118 did do the cell part but lost the wired connection and the dual radios in the process.
Forgive me for poking around in the dark here. I've done quite a lot of searching through the messages here (currently and over many years past) and I'm really trying to keep it all straight. It's difficult to distill everything down into useful steps, and not brick the router in the process. There's only 'so much' free time I've got to wrestle with this, so I try to avoid endless attempts of reloading/reflashing/rebooting.

Ok, setting and rebooting now...
Hmmm, things got different, not necessarily better. But I do feel like there's progress.
Trouble is, now my wired ports don't even light up at all.
Fortunately I can still connect via WiFi. But at least status shows the right hardware, and both radios show up with the expected menu options.
Curiously the LED above the center button is lit up yellow.
Just no wired connections. I tried Admin->Factory Defaults and that didn't revive them. What's next? I want to tread carefully here, of course, to avoid bricking or otherwise making the situation worse...

Additional progress, I plugged in the Verizon UML290 4G dongle and configured the WAN to use Mobile Broadband. It seems to work! That is, I can make web connections through it, so Yay! on that front.

You're still working from a corrupted base config and you're just fixing parts of it
You really should flash back to a K2.6 ver and do a full reset
Then flash back to K3.x and re-configure fresh - don't reload old config
Lot of work sometimes but better to know you have a good fresh working config _________________ Soylent Green Is People ! =-=-=-=-=-=-=-=-=-=-=

did you use the nvram command to fix the mac addresses?
the lack of lights might just be a cosmetic issue. did you plug a computer into the wired ports but got no connection? _________________ Please state what make and model router plus the build number and type of DD-WRT you are using.

It can be fixed but it is maybe better if you flash Linksys OEM firmware in the dd-wrt upgrade gui and after booting OEM do a hard reset.
Then flash dd-wrt.v24-22118_NEWD-2_K3.x_mega-e3000.bin,
this should restore all nvram variables
