The Wi-Fi of my router (an 802.11ac-based chipset from Realtek) does not show up in any client. Actually, it never worked for me. However, when I run Wireshark in monitor mode, I see its Wi-Fi beacons both in 2.4 GHz and 5 GHz. Those are the Wi-Fi beacons from this router because the SSID is readable. However, however, Wireshark is not able to decode the remaining parts and declares the beacons malformed. My question: Has anyone ever seen such a behavior: Any idea, whether that is hardware, firmware, or simply configuration related?
I am asking because that router is based on OpenWrt, not vanilla but a distribution based on it. Therefore, going the software path would be some work. And if it is hardware related, I would instead go that path. And it is used; I would like to play a bit around and repair it. However, if you tell me, it is broken beyond repair, I will not continue and avoid wasting time. Therefore, if someone had seen that before and succeeded with approach XYZ, such an answer would be highly appreciated.
