Zyxel p-2812 current state and updating wiki

Mafketel · April 4, 2019, 6:36pm

in order to run the current snapshot there is a chicken and egg problem
The current snapshot holds the bigger kernel mtd partition, but it is also the kernel that needs it in order to boot.

For now the only way around is to compile the snapshot yourself, which is slightly smaller then 2mb and thus fits in the smaller kernel mtd partition. From then on you have a 3mb kernel partition size. and can update to prebuilt snapshot builds

If the initramfs+kernel would work so you could start the modem from ram it would be easier. But alas that is also broken...

So 2 mayor issues remain,
1 current U-Boot is not able to start the modem from nand
2 Initramfs errors out on startup since r47026

On a brighter note kernel 4.14.109 seems to have a lot less WiFi issues and I am currently stress testing to see if it drops the connection.

i don't get this. AFAICS at a sysupgrade the kernel is written to the kernel partition, and the rootfs to the UBI partition. If the kernel doesn't fit, sysupgrade fails. (And I hope before trying to flash it.) With your special crafted kernel, it will fit. But after a reboot, the UBI partition will be corrupted, as it's start address has changed. That will lead to a kernel panic, I guess. So how can you flash a prebuild snapshot after that?

Mafketel · April 7, 2019, 12:58am

that is how I see it too but the modem apparently not

Nope it does not fail it just writes and overwrites, it is not really safe but then again these modems are difficult to brick for you can always uart boot.

not so special the kernel just happens to be slightly smaller then 2mb no special option further.

You would think so, but it somehow works, I was ready to flash the UBI partition manually but it was not necessary.

Now I am not happy about:" it somehow just works", but I have done it a couple of times and it worked every time the only thing I can imagine that makes it work is magic and I mean the magic numbers to recognize partitions.

Anyway a real solution would be a working initramfs image, although I think the issue is in an U-Boot setting so it might be tricky to actually get it to work.
Bug report about initramfs error with possible solution.
https://bugs.openwrt.org/index.php?do=details&task_id=2226
no point in trying to figure out this temporary situation.

Anyway I flashed 18.6.02 back onto the modem to see if miraculously the WiFi errors have disappeared, so if you want the serial log of how I flash the modem to current trunk snapshot I can make one at the end of next week somewhere.

@Mijzelf quoting en praten tegen mijzelf is erg verwarrend

So here is the log of updating from 18.6.02 to snapshot.

in short,

flash from luci a self compiled snapshot that has the new size ubiblocks but has a kernel size of less then 2mb
flash from luci the latest snapshot from openwrt that has a kernel larger then 2mb

It is a bit longer then necessary for I made a mistake in selecting the image to flash.
it went like this

flash from luci wrong snapshot with to large kernel
tftpboot load wrong initramfs
tftpboot load booting initramfs
flash from luci a self compiled snapshot that has the new size ubiblocks but has a kernel size of less then 2mb
flash from luci the latest snapshot from openwrt that has a kernel larger then 2mb

anyway I guess you see that it works magically

Now the trick that it works is probably that:
The UBIfs is a filesystem above the flash layer and it reorders its writes according to how many times a sector is written on before. Hence the likelyhood it will use the first sector after the kernel is unlikely and hence it still can find the rootfs partition. The larger the kernel gets the more likely it goes wrong but 1 mb on 116mb there is lots of space for it to go right still.

Anyway I hope this made it a bit more clear.

So the unstable wifi has been solved, I have been using it for a while without significant disconnects.

https://bugs.openwrt.org/index.php?do=details&task_id=583

is closed now, If you want this fix in version 18 or 17 you might want to ask that... for now only fixed in snapshot from OpenWrt SNAPSHOT r9858-b6acb7b / LuCI Master (f138fc93) Kernel Version 4.14.111

lleachii · May 16, 2019, 6:52pm

Fixes are usually not back-patched to previous firmware version, hence the snapshot/master branch.

Mafketel · August 21, 2019, 4:05pm

so the modem is not allowing us to use the wifi anymore....

these are the relevant error messages:
windows 10 laptop says it can't connect to this network.
none of our android and iphones are connecting.
wired there is no issue

modem kernel log:

ieee80211 phy0: rt2x00lib_rxdone_read_signal: Warning - Frame received with unrecognized signal, mode=0x0001, signal=0x010f, type=4

modem system log:

daemon.notice hostapd: wlan0: STA 60:57:18:5e:c7:0c IEEE 802.11: did not acknowledge authentication response

sometimes these pop up

daemon.info hostapd: wlan0: STA 60:57:18:5e:c7:0c IEEE 802.11: deauthenticated due to inactivity (timer DEAUTH/REMOVE)
daemon.info hostapd: wlan0: STA 60:57:18:5e:c7:0c IEEE 802.11: disassociated due to inactivity

Firmware Version

OpenWrt SNAPSHOT r9858-b6acb7b / LuCI Master (f138fc93)

Kernel Version

4.14.111

since 18.06.4 should be running a newer kernel I will install this later today and see.... but feedback expected only after 60 days at least if it is not in the 4.9 branch

Linux kernel updated to versions 4.9.184/4.14.131

https://openwrt.org/releases/18.06/notes-18.06.4

disabling and enabling the wifi on the modem made us able to connect to the wifi again.

please don't update to 18.06.4 if you are running a snapshot ..... first kernel is at 4.9 so might not work second ... you will screw up your 3mb kernel partition and get some errors to try and fix it.

I could not find my smaller kernel snapshot with 3mb kernel partition so I uploaded the one I eventually found to

if you want it .... now available .... I thought I had shared it before .... apparently not

Mafketel · September 12, 2019, 10:41am

we got disconnected again ....
I should not have updated .......

Thanks. I used it to upgrade to 19.07-rc1, which worked flawlessly.

Mafketel · December 12, 2019, 2:33pm

Added some info for installing snapshots and version 19 firmware on the modem page

Is the mtd kernel partition increase 2MB > 3MB still neaded for 19.07.x or snapshots since I was able to upgrade downgrade from 18.06.5 to 19.07.x however both would crash/freeze no ssh/luci access within a day even a clean reseted config. Pre 18.06 was stable except wifi.

After upgrading the mtd partition size with @Mafketel github firmware and flashing 19.07.rc2 it doesn't crash anymore (maybe it was 1.5A 12V powersupply instead of 2.0A 12V).

As long as variable size is not available 3mb partition is preferable
if not necessary for the latest kernel .... it might soon be again since it is really close to the 2mb in size.
Going back and forth is pain and 1 mb less on 128mb seems like a very reasonable cost.

p.s. i did not check rc2 yet so I do not know the size.

walterav · January 1, 2020, 12:13pm

Device is sadly inaccesable again (~3 days up), the LAN switch ports leds are off and connecting a PC to those ports would say that no cable is plugged in. However the wan led is still blinking(random), device was configured as wan(eth) and wwan(wifi) however it has no current ip-lease and is not connected to my other AP anymore. The power supply is 12V 4.5A so that must be enough any ideas?

Better inspection shows that still 2 lan ports are active 1,2 but 3 and 4 and off, however no dhcp lease on 1,2.

altuntepe · February 8, 2020, 12:03pm

hi, i'm using P2812F1. openwrt wifi performance is very bad, it gives a maximum of 40mbps. and range is very low. No problem when I install zyxel 1.0 firmware, works at maximum power. How can we solve the wifi problem with openwrt?

klausenbusk · February 11, 2020, 10:48pm

I just managed to install OpenWrt v19.07.1 on my P-2812AC and it kind of works, The P-2812AC has a builtin Ralink RT5362 and a mini PCI port with a Qualcomm QCA9880, but the QCA9880 isn't detected.

So I tried modifying the dts file (status = "okay"), but now none of the PCI devices is detected. Afterwards I installed the newest snapshot on the device, and the builtin Ralink device isn't detected.

So WiFi isn't working in the snapshot it seems. Do the snapshots work for you?

Mafketel · February 12, 2020, 2:14pm

are you sure the drivers are installed and the configuration file is loaded?

klausenbusk · February 12, 2020, 2:36pm

Installing kmod-ath and kmod-ath10k didn't change anything, and dmesg and /sys/bus/pci*/devices/ only show a single device (v19.07.1, if I run the snapshot it doesn't detect any PCI devices at all).

klausenbusk · February 12, 2020, 4:30pm

dmesg log, as you can see 0000:00:0e.0 never shows up in the OpenWrt dmesg snapshot log:

Hi, I recently bought 3 zyxel P-2812-F1 routers for cheap. Now I want to install OpenWRT on them, so I bought an USB to TTL cable and started following the steps on de zyxel F1 page (https://openwrt.org/toh/zyxel/p2812hnu-f1).

I managed to get the device in CFG02 UART mode (although my rom version is not 1.1.4 but 1.0.5) and I uploaded openwrt-lantiq-p2812hnufx_ram-u-boot.asc. First I tried sending the file with TeraTerm (took a reeeaaally long time😒) and then I tried RealTerm (which was a lot faster😎).

The problem is that the device won't do anything after I uploaded the .asc file, it just stays in UART mode and it doesn't reboot. If I manually reboot by powering it off and back on, it reboots back in Z-boot mode (ofcourse, because the .asc file only gets written to memory:smirk:).

Am I doing something wrong? Or am I missing something important?
