I have a 3100, happy to test if needed
Hi arinc9, you are right. I tried flashing my RT-AC3100 with the official snapshot and I could not get the router to fully boot up.

Hi @arinc9 ,i flashed my RT-AC88U with your TEST4. My laptop,3 different iphones and samsung S21 all connect to 2.4 GHz wifi without any issue.(Only) my samsung S21 takes long time to connect to 5GHz and when it did it connects without internet.I tried every possible setting of 5GHz for 3 days then I gave up.
I meet the same problem with you. 2.4G works well and 5G can't get the ip address.

I had the same problem. 5G was either not able to connect or once disconnected was not able to get an IP. Especially with older Android-based phones (2016-2018) but had this happen with iPhone13.

My 3 iphones and laptop connect to 5ghz easily and get ip and gateway and dns, the problem only with samsung s21 which even it's connected with ip and dns but without internet
This patchset introduces dependency on bcm47xx_nvram in the NVMEM driver. If anything bcm47xx_nvram should be rather replaced by proper NVMEM usage across Linux kernel.
I can work on that but first I did some more testing.
First I verified this issue affects my Luxul XWR-3150 device as well. Not by default as NVRAM is stored on serial flash but I hacked code a bit to create fake NVRAM on NAND. I verified it affects XWR-3150 as well:

Just to be sure I decided to repeat that test with D-Link DIR-885L which uses just 1-bit ECC. I also verified this problem using it:

My AC88U boots fine on current snapshot which includes this commit. Keep in mind I had to revert commit ef76b6ff3e ("bcm53xx: Add support for D-Link DIR-890L") to compile the image as I get this error otherwise.

I had a look at it and the error occurs because the D-Link 890L expects u-boot build for it (to get around a limitation) but it's not selected by default.
Select 'Bootloaders > u-boot-dir-890l' or adding 'CONFIG_PACKAGE_u-boot-dir-890l=yes' to the '.config' file solved it for me, the build succeeds.
Unfortunately I don't know what to change so that it's selected per default.
Do I need to perform any further tests?

No need, Rafal's patch fixed the issue reported on this post. And the fix is in the latest snapshot images.
So,Do you advice to flash RT-AC88U with the latest SNAPSHOT (r23885-703d667a0c) please??

Yea - I used this last night (build date 4th Sept) and it booted fine.
If you use the current release build version it'll brick and you'll need to recover.

Thank you dear,I will give it a try at the weekend.
Hello,
Can someone help me confirm that 5gh wifi works on the Asus 88u HW A1.
I installed the latest OpenWrt SNAPSHOT version r23885-703d667a0c / LuCI Master git-23.236.53281-98e3743 but it doesn't work.
I connect to the 5g network but I don't have internet and the router doesn't receive ping either. The router assigns ip on the 5g network.
