Yes, the router is my gateway to the modem of the provider (cable Germany - Provider).
Old kernels get end-of-life'd and stop receiving updates.
See here; I'd say GUI resets (after) are fine unless you run in to issues. You could try going straight to the latest k3x E3000 build, since it is a trailed build, but I've not seen reports of others doing that.
hello jwh7,
is there an "End of LifE" date for the K2.6 kernel ???
I was still searching for comparisons and came across an interesting report.
The report is from 2017 and explicitly shows that the K.3x kernel is much slower in speed than the K2.6.
Especially when we are talking about routers of the E series.
The test ran on a Linksys E4200 and I even only have one E3000.
If the "End of Life" date for the Kernel K2.6 lasts another year or two, I'd be better off with the K2.6. on the way or?

The 2.6 Linux kernel is no longer maintained, Brainslayer and other non-ddwrt devs backport some fixes to it (and the 2.4 kernel) to fix specific bugs and vulnerabilities.
As for K3X, I prefer the K3X kernel on my routers because it has better support for USB. It is also still supported, at least the 3.18 kernel that most routers use is. 3.10 is used in some, that is EOL now though. _________________ Before asking a question on the forums, update dd-wrt: Where do I download firmware?

hello ian5142,
thanks for the information.
that means the LTS version for 2.6 is actually already expired ???
or does it retain the unofficial LTS status ??
USB would not be so important to me because I do not have USB hardware on my E3000.
For Filesahring I have a separate NAS and I do not have a printer on the router.
do I have to do all 3 steps during the update? In the tutorial it seems like these 3 steps have to be done on the very first flash.
But I'm already on a * nv60 build.
I just do not want to run the risk of brick my router.

If you are already on an NV60 build, you should be able to flash a newer NV60 build. Just make sure that it is smaller than 8MB (8 000 000 bytes).
Also, if you are coming from a build older than about 6 months, I would suggest a reset to defaults. _________________ Before asking a question on the forums, update dd-wrt: Where do I download firmware? I suggest reading it all.

hello ian5142,
I was aware of a higher version with K2.6.
I may have expressed this badly.
I think rather if I follow the suggestion to update to K3X.
I read through the manual but am unsure of step 1.
Since I'm already on a * nv60k version, I'm not allowed to install a version without "nv60" in the name anymore.
But in Step 1 I should do this.
I would not but that the router ** BRICK
I just realized that there is no NV60 build for K3X. I guess in that case, just flash the e3000 mega build, from the K3X folder.
What version of dd-wrt are you running now?
The upgrade path I would take would be:
1. Flash 34311 - K26 NV60 mega, then reset to defaults
2. Flash 34311 - K3X e3000 mega, then reset to defaults
3. Configure all of your settings manually. _________________ Before asking a question on the forums, update dd-wrt: Where do I download firmware? I suggest reading it all.

hello ian5142,
i have now a dd-wrt.v24-*****_NEWD-2_K2.6_big-nv60k.bin Version on a Linksys E3000
With this *nv60k Version may I only install versions with *nv60k in the name.
Otherwise there is danger to the router too brick.
the tutorial says, however:
K3.x upgrade
To update your E3000 unit to K3.x. These EXACT builds MUST be used to upgrade to K3.x for the first time. Any other builds will soft brick the device....Start with a hard reset then follow the steps below.
Three steps required to get K3.x on the unit:
1 - K2.6_21676_mini_e3000 ....wait 5 minutes....hard reset.....next load from the GUI
2 - K2.6_21676_mega_nv60K ....wait 5 minutes....hard reset.....next load from the GUI
....after that you can put a newer K3.x_mega build on directly...no need for nv60K builds any longer.
Step 1 is a version without nv60K. --> Here I see a danger for my router which already has an nv60K version.
The rest (Step 2 and Step 3) is fine since this nv60K versions are.
Does not one follow the instructions ->Any other builds will soft brick the device.
I do not know if the tutorial assumes an already installed nv60K version or a stock version ?!
Then add a step to upgrade to the latest (with e3000 in the name, K3X). _________________ Before asking a question on the forums, update dd-wrt: Where do I download firmware? I suggest reading it all.

Yes that was from January 2017, and SFE accelerated NAT was added in late summer, making k3x faster than k2.6. See the SFE link in my signature.

hello ian5142,
ok, than with this Step.
1: Hard Reset 30-30-30
2: In Step 2 with the 2 - K2.6_21676_mega_nv60K or with a 25697er version....I still have the dd-wrt.v24-25697_NEWD-2_K2.6_big-nv60k.bin version.
Then the mega must also be out from this series.
after Mega Patch
3: Hard Reset 30-30-30
4: - K3.x_21676_mega_nv60K ( here also determined from the 25697 series ??)

ok, good to know that NAT works faster with it.
Are there any readings that can be compared with the January report?
What else do you say about the update? Is that as ok as I wrote it ian5142 ?
Update: ... i have a Problem:
The Last " dd-wrt.v24-23598_NEWD-2_K3.x_mega-nv60k.bin " is in the 02-19-2014-r23598.
these are all versions under my version.
Can I easily downgrade my version?
I need a Mega Version from 2014-r23598 and the last K3.x_mega-nv60k Version.
Only then I can take the current K3.x version without nv60!
I would use the latest, same file names but instead of using either 21676 or 25697, use 34311. I understand you are already on a higher build (25697>21676) but you must downgrade to upgrade So you would get:
1: Hard Reset 30-30-30 (Factory Defaults, through GUI, don't use the reset button)
2: Flash - K3X_21676_mega_nv60K
3: Hard Reset 30-30-30 (Factory Defaults, through GUI, don't use the reset button)
4: - K3.X_34311_mega_e3000
5: Hard Reset 30-30-30 (Factory Defaults, through GUI, don't use the reset button)

I guess I'm not getting the point of this thread...you already have the instructions to upgrade to K3.x.
Reset the router...and follow steps 1-3 with those builds EXACTLY...when finished...load the latest K3.x_mega build.
Its not that hard folks!!!!

seriously ??!!
As you can read (I hope so), I already have a xxx version on the device!
So I can not install K2.6_21676_mini_e3000 !!!
That would destroy the device.
The K2.6_21676_mini_e3000 I can install if I have a Linksys version on the device!
The K2.6_21676_mini_e3000 version is the first version I need to install on an E3000 when I come from the Linksys version !!
So thank you for the nonsensical advice.
If the exact procedure is too much for you, you do not have to write an answer!
