D-Link DSL-2730u Compiling for WiFi?

For Developers
1

I run OpenWrt generic images on a couple of old DSL-2730u's I use as wired routers, the pictures in the wiki are mine:

But the WiFi (BCM4313) never worked. I had mentioned that in the wiki, but someone (user 'dejavu51') recently edited my statement to claim that wifi will work:

if you build kmod-brcmsmac driver from openwrt source with “Use firmware extracted from broadcom proprietary driver” disabled.

I tried following the instruction and building from source with said setting unchecked, but the driver refuses to work. If it can be made to work perhaps it can be added as an official build (sans DSL of course). I will be extremely happy to test any images or build any configs. Or any suggestions whatsoever.

The kernel says this with the claimed working driver:

[ 15.535055] brcmsmac bcma0:1: mfg 4bf core 812 rev 24 class 0 irq 31
[ 15.542493] ieee80211 phy0: wl0: brcms_b_attach: Unsupported Broadcom board type (0x4313) or revision level (0x0)

In drivers/net/wireless/broadcom/brcm80211/brcmsmac/main.c
--- if (!brcms_c_validboardtype(wlc_hw)) {
+++ if (brcms_c_validboardtype(wlc_hw)) {

--- brcms_c_get_macaddr(wlc_hw, wlc_hw->etheraddr);
+++ u8 my_tmp_mac[ETH_ALEN] = { 0x00, 0x10, 0x18, 0xff, 0xff, 0xff };
+++ memcpy(wlc_hw->etheraddr, my_tmp_mac, ETH_ALEN);

and you happy

Did you end up getting the WiFi drivers to work?

Sadly no. I eventually upgraded the entire network backbone of four nodes to gigabit and had to retire them. When the Mi router 4a gigabit hit ₹999 at one point I had no excuse. They run great on OpenWrt.

That really sucks. It's sad to see them go to waste because of just one driver when OpenWRT runs alright on them. And my use case does not really need a lot of bandwidth and these routers are good enough. But thanks for the tip on the Mi routers.

@Dynabook, I was wondering if you could help out with regards to this.

That is Broadcom for you, in a nutshell.

Some people reported saying they got the WiFi drivers working for them making me wonder where I'm going wrong.
