Wifi sometimes stop working - not hardware installed

[alexmenn]

Hello all! I'm working with internal dw1560 in my notebook pro and everything is OK, I'm using original antennas and speed is great. But sometimes, after sleep, the laptop says that there is not hardware installed, and I have to reboot to fix it.

Sometimes (less times), when I reboot, after boot, the systems says too there is not wifi hardware installed, and I have to reboot again. Any clue?

@alexmenn you have this issue since you updated your EFI recently?

Anyone with internal BMC having this same issue?

[alexmenn]

No, I have had this problem since HS :)

@alexmenn Hi, since it’s a problem related to third party hardware, you can send trouble shooting to tonymacx86.com to get professional help. @influenist I installed a BCM943602CS card five months ago and it works perfectly.

[alexmenn]

@stevezhengshiqi Ok, I will ask. I saw you bought your chip + adapter in taobao. I can't buy there because I don't speak Chinese and google translator translates just some parts, not the full web. Can you tell me if this product on ebay is OK?

I have my actual wifi card installed to original antennas as owenlars says in his guide. But your BCM943602CS has 3 antennas. So, can I connect 2 of them to original notebook antennas and connect 1 extra antenna between trackpad and battery?

@alexmenn I think that is wrong adaptor,... you need key m or b, the link you provided is key a/e so it won't fit, also about the antenna I'm sure you can connect wifi one to original port and Bluetooth one under trackpad, but, you may want keep original intel wifi card as the apple one don't work well on linux and windows(need driver), as discussed on steve repo, go check them.

[alexmenn]

You're right. Key m or b, ok, but what kind of connection uses the chip BCM943602CS? I cant find any on ebay.

[Menchen]

@alexmenn I think it's apple own one connection,12+6 pin, and that port to key m is pretty rare... But I found one on aliexpress for you.

Only adaptor .Bluetooth should work if you solder usb bus. https://m.aliexpress.com/item/32949190082.html?pid=808_0000_0101&spm=a2g0n.search-amp.list.32949190082&aff_trace_key=&aff_platform=msite&m_page_id=1488amp-N9L0BcBVwnB6p_6y_KarrQ1541246198851

[alexmenn]

Hmm seems to be perfect. When I cut it, will it fit in the m2 slot?

[Menchen]

@alexmenn I don't own that adaptor, but it should fit without problem, as the m.2 size that we have is pretty standard.(designed to fit a ssd, with is longer than wifi card.)

[alexmenn]

Great. Then, I will buy this too https://es.aliexpress.com/store/product/Broadcom-BCM943602CS-1750Mbps-802-11AC-WiFi-Adapter-with-Bluetooth-4-0-BCM43602CS-A1425-A1502-A1398-WIFI/1194050_32782442052.html?spm=a219c.search0604.3.64.37217126i7eiH5&ws_ab_test=searchweb0_0,searchweb201602_2_10065_10068_10547_319_10891_317_10548_5728815_10696_10084_10083_10618_10307_10820_10301_10821_10303_5733215_5733315_328_10059_10884_10887_5733115_100031_5733415_5732615_321_322_10103_5733515_5727015_5733615_5727515-5727015,searchweb201603_55,ppcSwitch_0&algo_expid=e85903d5-42a3-4aba-a4a4-64aebbc50624-8&algo_pvid=e85903d5-42a3-4aba-a4a4-64aebbc50624

Is OK too? to make my combo chip+adapter.

[Menchen]

@alexmenn you also need antenna.... 3 antenna or two wire to connect to original one (I think you already have it.)plus a antenna for Bluetooth. Also about usb wire,it seem normal wire that you can find on local shop? Not sure about USB wire is equal than a normal wire.... and it's seem that adaptor have a usb socket maybe you should search more about it..

[alexmenn]

I have few wires to connect original antenna to chip right now. I just need one more antenna for BT, but I think I wont use BT with this chip. I just need a stable wifi which works after sleep :)

[Menchen]

@alexmenn well it's up to you, but Bluetooth is powered.. so wasted power. (You also have paid for a card that have native Bluetooth, so no more harassment kext)

[alexmenn]

Hmm ok, bluetooth will be nice, but how can I "connect it"? Im sure I will have to solder some wires...

EDIT: ok, I will follow this https://github.com/stevezhengshiqi/XiaoMi-Pro/issues/7 :)
