@IONK

You have no need to double flash, factory to dd-wrt is enough on any build to get you that dd-wrt build on initial flash then followed by nvram erase && reboot and manual reconfiguration, the webflash is for upgrading from an older to newer build only.

As for identification of the board it likely meaningless you would need to check the source to confirm if the initialization is shared between different machines.

Missing settings are to be expected, after the builds from last ice age things change, if it is a bug or not, no idea.

I've recently bought 2 new DIR-868L Rev A1. After loading factory-to-ddwrt.bin (09-03-2022-r50057) then dir868a-webflash.bin (09-03-2022-r50057), there's no 5GHz under /Wireless_Basic.asp: both wl0 and wl1 showed 2.4GHz (sorry no screenshot). nvram erase && reboot didn't help. Choosing the correct Time Zone under NTP Client Settings didn't help.
After loading dir868-webflash.bin (01-20-2015-r25974), there was 5GHz under /Wireless_Basic.asp. I changed the Regulatory Domain setting under /Wireless_Basic.asp, then flashed dir868a-webflash.bin (09-03-2022-r50057) again, after that 5GHz setting appeared in r50057 (same procedure as mentioned by ukirneK, mikhail51, karel1980, kyanox, dlinkrouter, digikim. Steff012 had the same issue but he didn't report back if the fix worked.)

Now both my DIR-868L have 5GHz, but both of them show "880L" under model (expected: 868L), same issue as reported by dlinkrouter. nvram erase && reboot doesn't help. nvram set DD_BOARD=Dlink-DIR868L && nvram commit && reboot also doesn't help.


there can be just one answer. you messed up your factory nvram. the detection is done by the nvram settings

The factory-to-ddwrt.bin (09-03-2022-r50057) is only 6MB but the dir868a-webflash.bin (09-03-2022-r50057) is 26MB, so I suspect they are not really the same. I've read somewhere that the first flash from stock needs a smaller firmware to fit the size limit, after ddwrt is loaded then subsequent flashes use the full feature image, but that info may be too old and not applicable for all devices. Also, after loading factory-to-ddwrt.bin (09-03-2022-r50057), I see "mini" in the build info instead of "std", so I just flash again using dir868a-webflash.bin (09-03-2022-r50057), just in case.

Both of them are brand new units in sealed retail boxes with stock firmware. After unboxing and connecting to them, the first thing I did was to load factory-to-ddwrt.bin (09-03-2022-r50057), then dir868a-webflash.bin (09-03-2022-r50057), then I realized there's no 5GHz setting. So I loaded the very old version dir868-webflash.bin (01-20-2015-r25974) that recovered the 5GHz, but is there any chance that same old version broke the model number?
In case I have somehow messed up with the factory nvram, is there any impact on the functionality? Is there any way to recover?

From dlinkrouter:
dlinkrouter wrote:
After going back to 25974, the device model was correct in the status.
I haven't tried that, but does it give any hint about the cause of the issue?

Additional info: my home DIR-868L Rev A1 is in Repeater Bridge, and this one doesn't have any issue with 5GHz or model number, but I forgot how I initially flashed ddwrt to it. Somehow I have dir868-factory-to-ddwrt-r25974.bin and dir868-factory-to-ddwrt-r34929.bin modded by quarkysg in my old folder, probably I used one of them.
Additional info 2: somehow my home 868a only has CTF after nvram erase && reboot, but both 2 new 868a have CTF+FA after nvram erase && reboot. Is there any chance that there are multiple hardware versions of "Rev A1"? All of them show BCM4708 on /Status_Router.asp though.

You maybe right, re: flash size, I wasnt thinking about stock retarded flash limits.

To confirm board identification snafu you should dump the older build nvram to text file and look it up, same with regulatory domain information. then compare the nvrams from old/new version.

to dump to tetx file do do nvram show > /tmp/somebackup-name-date-build-version.txt

No idea why you would need to flash an ice age build to get 5GHz or Regulatory domains to show up, but this being Broadcom wouldn't surprise me if its buggy.

Also since you flashed an ice age build clear your browser cached with ctrl + f5 its known to cause issues with new builds. If you're using Chrome you may need to restart browser after cache clear.

re: ctf and FA, multiple reboots required.

I tried doing a side-by-side comparison between the nvram of my home (working) 868a Repeater Bridge and new (wrong model) 868a Gateway, but there are so many differences and I quickly gave up. But I can confirm all variables with "board" are the same except for dd-board: 868 vs 880. I can PM the files if any developer needs (sorry can't attach here, too much sensitive info)

all 3 router went through multiple reboots and the settings stick (no FA remains no FA, with FA remains with FA)

I'd be interested in the differences of cfe.bin and nvram dumps on all devices. That may give further information required to delineate any detection issues as well as the 5GHz issue.

this case may not be the same as the issue reported in the wiki, because the issue mentioned in the wiki is about network does not show up but 5GHz settings are still available in the control panel page.

Thanks for the inputs. Because I'm a layman, I'll appreciate the step-by-step instructions with specific commands to execute (together with the rationales if possible), so as to avoid giving unrelated/useless info that wastes my time but doesn't help solving the issue and may potentially confuse everyone. (e.g. should I restore to stock then flash ddwrt again? which version of ddwrt to flash? should I do the factory reset / nvram erase && reboot after certain step? should I take screenshot of some pages after each step? etc.)

If it helps, I just received a version A DIR-868L too a couple of days ago. After loading factory-to-ddwrt.bin (09-03-2022-r50057) then dir868a-webflash.bin (09-03-2022-r50057), I too encountered that there was no 5GHz, and the router model came up as Dlink-DIR880L. I did not downgrade the firmware to the old version so the model number issue would not be related to the downgrade.

Following this thread to see if this gets resolved.

How about CTF & FA?

I just did a nvram erase && reboot , the router model now shows up as DIR-868L.

Try the following commands with ssh

nvram set ctf_fa_cap=1
nvram commit
reboot

This works for me on my DIR-868L A1

Yes, those commands make FA appear again.
For my router, at first FA setting was there, but after a few nvram reset then it disappeared, so I'm not sure if FA is supposed to be there or not. Here's a portion of log after the 2nd reboot.

I've recently bought another brand-new Dlink DIR-868L RevA1.
Original firmware version on the device is 1.00SH.
After loading r51040 factory-to-ddwrt.bin, device info shows DIR880L, no 5GHz.
After nvram erase && reboot and loading r51040 dir868a-webflash.bin, device still shows DIR880L, no 5GHz.
(No 5GHz means both wl0 and wl1 under wireless settings show 2.4GHz)
Subsequent nvram erase && reboot doesn't fix the issue.
Following the previously mentioned workaround, 5GHz is back but device still shows DIR880L.

Obviously in this case I didn't do any funny thing to mess up with NVRAM.

looks like the nvram got screwed up. the capabilities of the wifi chipset are defined by the factory nvram data

there can be just one answer. you messed up your factory nvram. the detection is done by the nvram settings

Brand new user of dd-wrt, got dir-868l 2nd hand for a steal, flashed factory-to-ddwrt.bin and then dir868a-webflash.bin from 12th of January. Got the same problem - no 5Ghz band. Router came with original 1.07 firmware and is A1 revision. Too many people getting the same problem for this to be a coincidence or all of us doing something wrong.
Would read up if I can get this resolved with the suggestions from here ..
