wireless networking – How to connect to remote points via wifi antennas on towers?

The two points don’t have a direct line of sight, so I am thinking about using an antenna on a tower near one point to transmit to the other antenna on the second tower, and from this tower, transmit to the final point. However, I am not sure how do two antennas (one receiving and one transmitting) communicate. Can a router be used as an intermediary between these two antennas?

applications – Some apps only work on wifi

I have a few apps on my phone that for some reason only work on wifi. It is an email client and a public transportation app.
I tried reinstalling the apps, clear cache and data, clear cache and data on Google Play Services, resetting network settings but nothing seems to work. Is there any way I can make them work on mobile data as well?

wifi – Can someone create a fake phone number and impersonate my IP address?

I’ll try to keep this short. I am involved in a defamation civil lawsuit. I did not author the posts, but the plaintiff believes I did and seems to be doing everything in their power to make it seem like I did.

Every time there is an event in the case in my favor, I get some sort of notification – reset request for a social media account, a verification code for various dating apps, etc. I only began receiving these when the case began. Perhaps trying to dig up dirt on me, but unable to.

Yesterday was a case event and this time, a masked phone number texted them in the middle of the night threatening to post embarrassing photos/videos of him/her being cheated on by their spouse. Again, NOT me or anyone I know. Something is very suspicious about this and I’m afraid of being set-up on their end. They do know my address and IP address. They do not know the new WIFI password. Maybe this is someone legitimate, but the timing is highly suspicious which makes me think there is foul play on their end.

So my question is, could they set me up? I mean, could they have set-up a fake number and made it look like it came from my Wifi? Or really me in any way? I wouldn’t be surprised if they hired a hacker (they are these types of people). If someone on my network accidently clicked a suspicious link, could they get in? Is there a way for me to tell? I want to be ready for the worst when the subpoena comes back.

Thanks in advance for any help!!

wi fi – Simulating WiFi device in emulator with mac80211_hwsim kernel module

I am looking to simulate an additional WiFi device in a rooted android emulator (to simulate a device my company makes). So far I have found the linux kernel module, mac80211_hwsim, which seems like it would help me create virtual networks like this. I believe this is also the mechanism that the emulator uses to create its fake wifi network already. I have found /vendor/bin/mac80211_create_radios which seems to allow me to access that module (to create more channels / radios which appear in ip show link as wlan*).

If this is in fact the right way forward, once I create some more channels for that kernel module, I want to be able to connect to a program on my local computer after connected to this other WiFi network (similar to how maps to the host computer). (this looks helpful with the redir command)

Does this sound reasonable and does anyone have some tips going forward? It’s been challenging to find information that is relevant to Android in this area.

apache http server – Throttled speed to specific IP address from within home WiFi only

I am experiencing a weird problem where:

  • Accessing my own dedicated server at a hosting provider in France is slow between the hours of 6pm and 10pm.
  • Just accessing this particular IP is slow, not everything else
  • Accessing the IP from my phone for example is fine

I called my ISP and they say they don’t block or throttle anything. I also reset my router completely but the problem persists.

I can download files via ssh inside my server no problem and at full speed. I contacted my server provider, they ran some tests and they get full speed.

What can I do? How can I find out what is causing this issue?

wifi tethering – Stream music to Wi-Fi speakers

I am new to the forum and to Android as I am migrating from iOS. I am trying to find an alternative to Apples’ Airplay to wireless speakers in multiroom.

I do not have an internet connection at home and I am connecting the speakers via hotspot (the main hone – Samsung) and controlling them via an old phone with the dedicated app (AudioPro). With an Airplay as the main phone, I could use Airplay to stream directly to the speakers – or group – in the hotspotted network. I believe the speakers supports also DLNA.

I am wondering if there is a way to achieve communication between the main phone (provider of the hot spot) and the linked Wi-Fi speakers. I would like to stream apps eg Mixlcoud, Soundcloud, etc directly to the speakers.

If possible I am not looking for:

  • Bluetooth solution: beside that to me Wi-Fi connections work better in AudioPro, but I do not want to have to reconnect the phone to a different device every time I change room or speaker system;
  • Options having their own player: e.g. BubbleUPnP can stream local files to the speakers but to my knowledge it only features few online music streaming services: I guess my request is similar to this one: Stream any audio to DLNA/UPNP speakers
  • Options requiring rooting: e.g. AirMusic seems to offer the function on rooted devices and I am not comfortable with the idea. Is rooting the only option to achieve such communication?

Spotify is able to see and stream to the speakers fro the main phone.

Any help or suggestions greatly appreciated.


wi fi – Android phone: suddenly unable to connect to wifi

I’m having trouble connecting to a wifi network on my android phone.

I was connecting just fine for the last few months, but today it just stopped connecting.

It’s not airplane more, and I haven’t run any updates.

I tried “forgetting the network” and reconnecting again, but it keeps saying “Couldn’t connect to network”.

Have I been blocked? Is there anything I can do?

wireless networking – Windows Update KB4577266 broke WiFi and cannot be uninstalled

The Windows Update KB4577266 broke my WiFi and I cannot uninstall it.
Before trying to uninstall, I tried the following actions, all unsuccessfully:

  • Activating Airplane mode and then deactivating it
  • Disabling the WiFi driver in device manager and re-enabling it (cannot update driver, as cannot connect to WiFi)
  • Restarting the computer
  • Forgetting the network before trying to reconnect (it can see networks, but gives an error when trying to connect to them)
  • Using the troubleshooter

I have two updates from the recent hours:

  • KB4579311, which I successfully uninstalled, but it didn’t solve my problem after restart
  • KB4577266

The problem with KB4577266 is:

  1. When I right-click it, it won’t response (usually it should show a context-menu with an Uninstall option)

  2. When I open a CMD console as an Administrator and run wusa /uninstall /kb:4577266, I get the following error message:

    Windows Update Standalone Installer: Security Update for Microsoft Windows (KB4577266) is required by your computer and cannot be uninstalled.

How can I force Windows to uninstall it?
