Is that a switch or a broken part of some type? Unable to see it clearly. Perhaps not related to the wifi fault.
Here is a good video on this model:

The wifi cable should look like this:

Was this unit water damaged? It is possible that the BGA balls are corroded if there was liquid damage to the phone and the WIFI module is not visible to the logic board.Leave a comment:

What is the history? Are you sure the fault is hardware related?

Samsung S21 FE wifi not working
Hi everyone, I have a Samsung S21 FE with no wifi. I can't see the classic antenna cable so i suppose it is integrated in the circuit of the mobo. Can anyone help me with this?
I have very good skills in soldering and stuffs.
Thanks

Hello, first of all - thank you in advance for help.
I got an Getac S410 G4 notebook with Intel(R) Wi-Fi 6 AX201 160MHz. Everything works fine, but we need to have another Wifi NIC because of VW/Audi Cars diagnostic software.
So we added this one Realtek RTL8822CE Wireless LAN 802.11ac PCI-E Network Adapter to a free slot PCI-E 3.0 x1 port.
NIC is installed correctly, basically it works, but we dont know how to enable the Wifi on it. It seems like it is still in Airplane mode - we are unable to turn of Wifi on this card. BUT - this card will turn on Wifi itself, after some time,...01-29-2025, 05:29 PM -
Hi,
I have an really very weired issue with ASUS ROG STRIX B550-I GAMING.
Some NVME (PCIe) SSD's are not working correctly in the second M.2 socket. An example of it is the SAMSUNG SSD980 1TB NVME SSD.
Some other NVME (I have only smaller ones) disk do work without any problem, also SAMSUNG disks, eg an MZVPV128HDGM-0000.
The behaviour is also really very strange, i.e.:- The disk shows always up in BIOS - so it is recognized, so far so good
- POST-ing with this disk with fresh Windows 24H2 installation (done in the M.2_1 socket) in the M.2_2 socket

I just wanted to post this here in case anyone else ran into the same problem.
I had a UN46ES7100 and the wired Ethernet connection worked, but WiFi did not. Any time I tried to set up WiFi it would either 1) Show the available networks for a split second and then exit the menu, OR 2) Cycle forever looking for available networks and eventually go back to the menu. I know that these WIDT20R often fail, so I bought a replacement from China, but it exhibited the same problems. I did a little more research and found the following online:"Problems: Ue65es8000 - while doing wifi network... -
Hi guys thanks to forum I was able to fix my Samsung UE55MU8000 yesterday that was having a corrupted firmware, but now after it work i could not make work the wifi look like hardware is missing cause is not even searching just load bar but then not showing any wifi connections near to me, in the about page look like wifi Mac adress is blank do you have any suggestion? -
WiFi menubar symbol shows hardware stays connected (even when issue occurs)
WiFi adapter shows normal connectivity symbol & stats: Using Opt+WiFi shows:
• Tx Rate: 867 Mbps
• RSSI: -44 dBm
• Noise: -90 dBm (same as working MBP connected to same router)
After ~1 min - 7 min, connectivity is lost (no traffic works) until I Disable / Enable WiFi (temporarily fixing again)
Inspected Antenna connections (look secure) & UP / DL is quick when working (same as good laptop)
• DL = ~400 Mbps
• UL = ~17 Mbps...
