I need to develop a feature that is required checking Wi-Fi settings state 'ON' or 'OFF' even if not connected to a WiFi network on Android! I need to display a pop up!

I've got a router Mikrotik hAP AC2. Recently I've updated RouterOS to version 7.1.3 and have found that 5GHz access point has issues.

My notebook sometimes disconnects from 5GHz wlan, and one of smartphones in my family doesn't connect to 5GHz at all.

Here is the plot of wifi signal strength, that I've collected using my notebook located in direct visibility of the router at the distance of about 5-6m.

Cyan line shows 2.4GHz signal and red line shows 5GHz signal. Numbers are -42dbm for 2.4GHz and -68dbm for 5GHz.

My impression is that generally this is not normal. I repeat, there were no obstacles between the notebook and the router, only thin air.

I've tried to reset configuration for 5GHz wlan, change its region, but without success.

How can I fix this?

Here are current settings:

I'm working on a Wifi auto connect feature and I am shocked how broken that API is.

I'm using now 5 different APIs and I still don't get it in a way the user would expect it.

I have a setting to enable wifi auto connection on Android 10+ I'll try this:

1. Check if I hold the ACCESS_WIFI_STATE permission with: ...

I need to get the RSSI of the networks and they MAC addresss to a IPS (indoor position system) program. I was able to get ssid, signal strength and security using the sample code, but not mac addresses. I tryed to use this, but itsn't working:

I think there's a way to generate a wifi qr with pillow and qrcode library in python. I had searched in the internet and there's no information.

I will apreciate your help. Thank's

When I use Wireshark to capture traffics with my wlan card with monitor mode already set, it only displays 802.11 frames. However, if I use Wireshark with managed mode wlan(promiscuous mode), it certainly displays 802.3 frames.

I searched for some related information and found out that 'network bridging' allows devices to convert 802.11 wireless packets to 802.3 packets. In case of packet capturing, pcap allows conversion.
(link: How to real time convert wireless packet(802.11) to Ethernet packet(802.3) in windows?)

So, Why is 802.11 to 802.3 frame conversion impossible when using monitor mode(not associated to the wireless network)?

Below are pictures of the situation. Thank you in advance.

I am working to connect 2 linux machines, each with this USB Dongle: https://www.tp-link.com/us/home-networking/usb-adapter/archer-t2u-nano/, to an ad-hoc WiFi network managed by B.A.T.M.A.N ( batman-adv ).

When run, this scripts show that both devices are joined to the same ad-hoc/IBSS network.

I statically assigned ip addresses and routes to both 'bat0' devices. However, I cannot ping or otherwise use the connection between the two devices.

What am I doing wrong and how can I use the mesh network in Linux between the connected client and server? Thanks.

My 'server' node is configured with this script:

I am transferring photo peer to peer. All things works fine but I am not able to get the photo(file) transfer speed i.g internet speed. Like MB the file is transferred. Second I want to fetch the size of that file.

We are passing photo in data format using MCSession

Due to privacy I cannot add the project code here but I will share the refrence github project that I followed. In project I am passing string and In my case its Photo. All things are same.

I checked in Stackoverflow but not found any accurate answer!

Thank You!

I've searched for some information about frame structure in wifi and ethernet in the Data Link layer and found out that the two frames look quite different. I am wondering if there is some method in the router that converts wifi frame to ethernet frame in a such network where wireless network is connected to wired network, like WLAN. Since I'm really new to this field, I may have some misunderstanding issues. Thank you.
