Have you tried installing bluetooth drivers from Acer site..?

Elliot85

i tried that yeah and nothing the previous pci wifi+bluetooth worked fine but some reason new one i got in don't want the Bluetooth working i don't even have it on device manger on device manger it shows the wifi6 perfectly fine but Bluetooth nope nothing it will only show the Bluetooth went i click on hidden changes but even then i cant even turn Bluetooth on or off thought settings i spoke to intel about it and there been like tried drivers from accer which have but there have said and suggest that accer need to help me with oem driver or some thing like that as i may need a driver for laptop model itself

Leostat

If you have swapped the card Acer won't have the drivers for it, it will need to be the Intel only ones. A couple of questions around it of that's ok

What is the driver pack has it installed?

What chip did you replace? Are the pin outs the same? Some chips use e key for the bluetooth (which is just usb) some use m key which is pci

Elliot85

the driver package install is all intel bt 5.2 lastest driver for chip mine is pci chip called Mini PCI-E WiFi 6E Intel AX210NGW wifi card Dual Band Mini PCIe with build in bluetooth 5.2 that what i got for my laptop all driver installed are from intel as been speaking to intel and there give me all drivers for it but there told me that apartly may need oem verision for it to do with manufacture of laptop sorry dunno why all sudden write gone big

Leostat

In device manager what's the version of the driver?

And what was the previous PCI WiFi Bluetooth chip?

Elliot85

lastest versions it shows for ax210 on network adaptor is version 22.20.0.6 and i dunno what bluetooth previous was but the chip that was already in my laptop before put new in model number is QCNFA344A ok just search it said bluetooth on that model what was in laptop before put new one in was bluetooth 4.1

Leostat

Was it this one?

I'm looking into it at the moment, bit I think the keying is different. The killer has two pins at e which I think are for usb 2, where the Intel chip has two pins at the back and two at the front

Could an ace confirm if the board supports PCIe m2 ngff A+E key, or just m2 ngff A key?

Elliot85

Qualcomm Atheros WIFI WIRELESS CARD QCNFA344A 2.4G: 300Mbps O6V2 K5Q9 | eBay that was excently same model one that was in laptop before i tryed to get hold of accer and even e-mail them and asked about wifi6 and bluetooth 5.2 pci got in laptop not working and asking about things like wifi works fine just bluetooth and new one got into slot prefectly fine how would i know if my motherboard supports that i am just confussed to why wifi6 work fine but bluetooth dont want to thought if wifi6 worked fine so would of the bluetooth build in it this is the new lastest one i got in laptop Mini PCI-E WiFi 6E Intel AX210NGW wifi card Dual Band Mini PCIe Adapter BT 5.2

Elliot85

And plus don't understand if board only supports different pci m2 why would wifi6 work prefectly fine with no problems but then bluetooth 5.2 not work at all usually i am pretty good fixing the problems but this one has really puzzled me i follow all drivers intel give me for bluetooth 5.2 and wifi6 and it not stopped wifi6 just the effect of bluetooth problem

Leostat

So on that card, there are three sets of pins, it only needs the 2 pins in the middle 'key' ,

The ax210 needs 4 pins in that middle bit.

I don't know if the laptop has pins for that key so I'm hoping one of the aces here can check the service manual to see if electronicallu they are hooked up to something. If they are not, that could be the issue. The slot is physically the same which is why it fits, bit it could be electronically diffent

It's only the Bluetooth which runs of that middle key. the WiFi uses the side pins which match up for a mini PCI 4x lane, it's still pci3

Elliot85

oh ok makes sence now yeah what i been trying to do get accer with all information about it and what problem is to help me or look into it to see if is maybe laptop pins but i like e-mail accer well over 2 weeks ago now is there like anyway i could check like on montherboard to were i installed new pci to were would know if laptop has the 4 pins i know went i like put new one in i made sure there matched pins same and had no different to them and could not see anything different but i only lookin at the pci of chips aswell make sure match pins on monther board

Leostat

There isnt a way for us to check, but the ACE's on this forum have access to technical diagrams and may be able to confirm my theory

You can try to tell visually on the mothebaord itself, but the board may have pins in all positions but not be electrically connected

Intel Wifi cards, in order to work with your laptop they should`t be CNVi and/or vPRO, so make sure yours is not one of them. What is the exact model?

Elliot85

oh ok so do think accer will look at it then as am fairly new to this as intel were ones told me join this communtiy cause accer respond to people comments it wired cause even the dealer got the ax210 from i asked him to make sure it would work for my laptop and he reassure me it work fine and were said in about covering like the black bits on back of pci which can some times make Bluetooth work

batmalin

What is the model of the wifi card? And here is not official Acer support channel, we are users like you.

Elliot85

model of wifi card is a

Intel AX210NGW to mini pcie

but i dont use the adpator and my laptop is a accer an515 51 if that is any help and ok did not know i am new like said to this and intel were ones told me to join cause there told me accer ones who help on here and read the logs as itel kept telling me that if driver dont work could be to do with some thing like oem version what ever there mean by that but everthing like windows is activce and all poper windows 10 pro 64bit

Leostat

Nah its nothing to do with the windows version, its the pinning. I really would recomend swapping it for another model

Elliot85

oh ok so that what stopping bluetooth from working then the pins is there like no apadtor you know could get for laptop so could put pci e wifi chip in to work for laptop well bluetooth at lest
