D-Link DSL-2750B H/W Ver: B1

Hello all,
I have D-Link DSL-2750B with hardware version B1, could I install OpenWrt?

Checking the supported device there are the DSL-2750B with version D1 and T1. Do I have any hope of being able to install it?

Thanks in advance for the support.

Without knowing the technical details of the unit, hard to say if "possible". That the other variants are running a slow (320-333 MHz), single-core, MIPS-based SoC and have Broadcom wireless don't make them an "attractive" target for others to work on.

I was really pleased to have found this post and hoping to get an answer on how to install openwrt on the D-link Dsl-2750b. Unfortunately nope.
If by chance you khabotz had more luck, let me know please.

@papou84, welcome to the community!

  • I wouldn't reply to a 2 year old thread expecting an answer
  • Especially since you didn't tag the person you inquired to - @kabhotz :point_left:

Lastly, his devices appears unsupported, can you clarify?

thanks for your reply yes I didn't tag the person. My bad.
It was more like a message in a bottle.
Enough poetry.
However I managed to install openwrt on this device. It's working. CFE install. Powering the router with the reset button pressed for 30s.
Configured a static IP to .
Typed uploaded the bin for the dsl-2040 if I recall. Works fine...
Another routeur that will have a second life.


Sorry for the delay but in any case I would not have been useful for the discussion cause I've not make other tests.

Thanks for the good new @papou84, I will install OpenWRT also on my device! :slight_smile:
