Hi, I’m trying to put back in use a d-link 2750B ver B, which used to work in trunk version from Nov 2015 (details here https://forum.archive.openwrt.org/viewtopic.php?id=42206 ). I’ve looked in ChaosCalmer but this firmware apparently did not make it to final release... I can’t find it in archive.openwrt.org/chaos_calmer/15.05/brcm63xx/generic/ and subsequent Lede version doesn’t work (no wlan)
Any hint?
Thanks!
R
Their devices pages appear to have links to the v18.06.1 firmware.
Hi unfortunately firmwares from 16.x onwards do not work, I tried all of them..
Thanks
R
What does this mean? Can you be more specific?
Do you get any error messages?
Yes, with 275X-D and 275X-T firmware (from 16.x onwards) it enters an auto-reboot loop, with 274X-F it boots but without wireless, as it was before the october 2015 trunk...
Thanks!
R
So a bit more info:
Any hint? @guisenges do you have the old working firmware by any chance?
Thanks!!
R
Since there doesn't seem to be any hardware information available for 2750B rev. B: Can you please post pictures of the inside, including the chips used on this board (SoC, flash, RAM)? Readable chip markings would be good.
Please mind that Broadcom chipsets have limited wifi supportability, see https://openwrt.org/meta/infobox/broadcom_wifi
Hi here is a picture: https://app.box.com/s/tidgk28gdt7a9dy1gea605poeqdiu8m7
The WLAN is an Atheros 9287 if you can't read it from the image...
Any hint on how I could try and link a physical interface to the wlan?
Thanks!
R
And the big black blob with unreadable chip markings is a Broadcom BCMxxxx?
Is kmod ath9k installed? Do any wifi related messages appear in dmesg?
Yes, BCM6328
Thanx!
R
Hi
yes with 15.05 (not 15.05.1) the ath9k drivers are installed and dmesg doesn't seem to provide any useful clue, at least to me:

Hi all, has anybody identified a possible clue?
Thanks a lot!!
R
Hi Riccardo,
did you solve the issue with not working wifi or at least have you been able to get custom image where wifi is working. I have similar issue now with DLINK 2741 which use BCM6328 and Atheros 9287 chipset.
Jan
no, I bought a new router sorry!
