Hi,

Flashing this router with factory-to-dd-wrt.bin dated "2017-09-08" on the router database renders the reset button of the router inoperable. If a user forgets the administrator username or password, the only way to access the router (if Telnet or SSH is disabled) is to use the "emergency room (a utility to flash the D-Link routers if the router can not be accessed by usual means)" to flash it back to stock firmware. The reset button can be used normally with stock firmware, although 30-30-30 reset seems to be not working for this particular model.

This is an important issue to be addressed because even when the Web UI of DD-WRT is accessible, the router can not be reset by using the reset button after flashing with the above mentioned version of DD-WRT.

Note: Although this router is advertised as an AC1900 3x3:3 stream router, it shares the same platform as DIR-882 AC2600 4x4:4 stream router (without the USB ports) and can operate as an AC2600 4x4:4 stream router as confirmed by D-Link. (source: smallnetbuilder.com)

Have you tried the latest version of WRT r34311 or later?

What happens if you hold down the reset button after turning on for 15 seconds? Can you access the OEM Recovery mode in your browser after setting a static IP address on a wired LAN PC?

I opened a ticket concerning this issue. Also erase nvram has no effect.

Got this issue also.....plus for some unknown reason my admin/root user I create when flashed deletes itself...and there is no way for me to log onto the router. DRI-882-A1 . I've just been using emerency room to reflash it when I cant get into it anymore. I'll try the newest version shortly and see if that fixes it...but what a pain to lose control in like 12 hours. And I tried 3 different versions.

Currently on Firmware: DD-WRT v3.0-r34929 std (02/12/1

Erase nvram now works from telnet but the reset button still doesn't.

Never had issues with erase nvram so long as Telnet Management was enabled followed by an immediate reboot.
However, the current 04-04-2018-r35667 resulted in slow web browsing.
Reverted to older firmware.

Browsing speed returned to normal/quick with the current 04-06-2018-r35681 version.

Still wish the reset button would work.

hello,
to the DIR 878 Users.
I only get 130Mb/s on my 2.4 GHz WLAN
DD-WRT v3.0-r35681 std (04/06/1
I had this problem with previous releases too

My WLAN:
Interface
Mode AP
Network NG-Mixed
Channel 6 + 2 (2437 MHz) Wide HT40
TX Power 71 mW (Auto)
Rate 130 Mb/s (displayed on Status)
WPA2 Personal


i tested some other channels and modes (auto, ng-mixed, n). cant get more than 130. a connected client gets only around 54-90 Mbits as WLAN Speed.

With 5GHz i get 1560 Mb/s

Are your 2.4 GHz speed is normal?

Yikes.... I wish I had known that! I have somehow manage to forget my login credentials for my 878 and I have been pushing and holding the reset button like a mad man! If I flash with the newest version, will it reset login informations to standard or maintain the current?
