On another note, there's an updated official firmware (v1.11) for the DIR-882 which fixes a compatibility issue with games consoles (XBone/PS4). Is this likely to be incorporated into DD-WRT anytime soon?

A flash of build 37305 (2018-10-10) doesn't appear to include this update and seems to have issues with an XBox one.

Just bought an used 882, the router is still on stock 1.0 firmware, flashed to latest ddwrt from stock firmware web ui.

I found the 882 took a while to boot up from either stock firmware or ddwrt compare to my wrt1900ac.

Also found that the cpu usage reported by ddwrt is around 70%, is that normal?

Haven't test it yet, will do a nvram erase before inputting configuration to test it.

Anything I should aware? Tia

I don't know how it's possible but for some reason, the admin password was modified at some point during my configuration and when I tried to access the router it was impossible.

After looking for some information I reached this deadend
https://svn.dd-wrt.com/ticket/6223

Essentially it's impossible to restore the ddwrt firmware to factory default in order to put a new password and restore the config back.

So I had to do all the process again: go to the recovery mode, install the 1.00 official firmware and then upgrade to DD-WRT.

I see that this issue has been stucked for the last 10 months, anyone has found any other solution?

If you were using chrome have a look at this:

Yep, I noticed this a little bit late. In fact this also happened some months ago with a 1043, but since I don't touch the routers much, I forget this from time to time.

Anyway, the factory default thing is an issue. Hope we manage to see this sometime.

Thanks, it was just right after boot up, it drops back down after a while.

First thing English is not my native language, so sorry for the bad grammar.

So as you would noticed form my first sentence this will be my first post in this forum. I really like the DIR-882 but not so much the firmware form D-link.
Mostly because in the firmware they released, there is a bug where on macOS the finder will not show the NAS. Sometimes it does but that’s pure luck. I can connect to it via the ip but that’s not really a solution for the Time Machine, where macOS should see the NAS to work properly.

Since I had installed padavan firmware on my old rt-n56u, I thought there should be an alternative firmware for my DIR-882 and i found it. So the last year was a try to get this bloody thing working with dd-wrt.

First thing with the dd-wrt firmware is, that the NAS shows up in finder and that’s great. When it works I get good speed, not the full speed (per WiFi) what the hardware is possible with the original firmware but close enough.
With the GC-WB867Di (rev. 4.3) in my PC I get the advertised 867 Mbps, when i use the original firmware on the DIR-882. With dd-wrt the highest I get is 780 Mbps on the 5 GHz net close enough for me.

So when everything works i can connect with the finder to my NAS with one click and best thing is the Time Machine does it’s thing, but high load via WiFi and the router will reboot. So it’s a bit luck for me, is the Time Machine Backup working or is it forcing the router to reboot. But it’s not only the Time Machine that will force the router to reboot, when I copy my backup from my main computer to the NAS it will also reboot. Not every time but often enough that I can force the reboot only with copying a little file with around 1GB for 2 to 3 times to the NAS. That's my main issue with dd-wrt, when it’s working like it’s supposed to do, it is really great but there is the stability issue I have with high load over WiFi.

I tested all Channel Width settings for the 2,4 GHz net, but it was glued to 130 Mb/s. But the 5GHz moved to up 1560 Mb/s.
So the Status page shows me for 5 GHz 1560 Mb/s (in the Manual they say 1733 Mbit/s) and for the 2,4 GHz it shows 130 Mb/s (in the Manual 800 Mbit/s). And still high load over WiFi and the router will reboot.

A week ago I did read in the DIR-878 thread to set the transmitting power to 80mW, it should help with stability, but it didn’t do the trick for me. So I tried different settings from 80 to 75mW till 70mW but I found out for my router 75mW brings it a little bit more on the stable side.

then with the builds 03-10-2019-r39137 and r39144 I had an odd behavior where the power LED was blinking orange and I could not open the router page, while i could still watch YouTube or browse the internet. I had to manually reboot the router and than I could open the router page.

Overall without the stability issues it would really be great to use dd-wrt on the DIR-882 and not to revert back and forth between ogrinal and the dd-wrt firmware.

Maybe someone with way more knowledge about that firmware has a hint for me to improve the stability.

thanks for your patience to read this long post.

FYI,
The DIR-882 does support 160Mhz.
(800 Mbps in 2.4GHz + 1,733 Mbps in 5GHz )
As Per the DataSheet:

I recently bought this router.

And under wireless is see very few option and am planning to install the latest DD-WRT.

Am pretty new to DD-WRT, so bear with me.

Which will be best release in terms of stability ?

All the features are working ? like USB Ports and WiFi no connection drops.

I use a PPPoE connection, so any known issue with this connection type ?

Also under Wireless Settings do we have option of 160Mhz Channel Bonding ? as i dont see it in the Stock Firmware ?


Hope to hear soon from the Gurus.

Thanks in advance


the wifi hw on the dir882 doesnt support 160 mhz. if you want 160 mhz use a qca9984 based router like the netgear r7800 or the netgear r9000. these routers do support these features and much more due the much better driver and chipset support

Thank for this build! Trying it now on dir878, lets see how is stability... got a reboot with offical r39296 after 6 and a half days :/ also not sure how interested you are with fixing minor bugs... for example you cant set custom ntp server, however client is obviously working since it sets time from pool.ntp.org, also you cant disable ssh (option does not save) and syslogd does not start with remote loging enabled, i would suspect this is because on offical builds syslog remote loging starts syslogd with -R <ip> option, but on this build syslogd complains this is invalid option.

Hi,

i spent several hours today trying to install DD-WRT on the DIR-882 without luck.
I could install all dlink firmwares and i tried the recovery mode and with loading the start page and selecting the file and restarting again to recovery and upload then but it always says upgrade failed when using factory-to-ddwrt.bin.
Is there another factory-to-ddwrt.bin which works ?

I also tried it with curl like this:
curl -v -i --connect-timeout 99999 -m 99999 -F "firmware=@factory-to-ddwrt.bin" http://192.168.0.1/

and waited some minutes. Still i always end with the original firmware.

Any ideas ?

You can try the crash recovery methods mentioned at the existing topic to install dd-wrt: D-Link Dir-882

NB: Those released in March or earlier should work.
Number of negative experiences reported of the April releases.

Good luck.

Hi, i used the recovery mode because we know that the normal upgrade does not work (also downgrading is blocked then). I would install a newer dd-wrt firmware after the factory-to-ddwrt but it fails so far to install the start image.
Also i have no red LED which flashes but an orange one. I guess my model dir-882 is newer than the one which was used for the factory-to-ddwrt.

Hi all,

i followed the advice of kabi and used windows (!) with iexplore (!!) to install the factory-to-ddwrt.bin image and voila it worked without even to restart twice into recovery mode.
This is akward. No other browser worked and not even curl. Who did this recovery mode ?

Thanks kabi

Hi All,
I have been having sporadic drops and finally after setting up remote logging I captured a stack trace.
But I have no idea what can be causing this.
