networking – wireless extenders USED AS wireless access points

please help me out!!!!

I live in this three-story building,
one household basically.
I have 500mbps with OPTIMUM (only choice in the neighborhood..sucks!)

basically we have main line of internet on the 2nd floor and 1st and 3rd floor is using the networks off of it.

So the setup I have now is
3rd floor: using wifi off of 2nd floor + LINKSYS RE6300 AC1200 wifi extender for dead zones
==>8-10mbps for using wifi extender in the dead zones and upto 90mbps for using wifi off of 2nd floor

2nd floor: MAIN MODEM and ROUTER (Linksys mr9000 AC3000 allowing upto 25 devices) ===>upto 420mbps

1st floor: using wifi off of 2nd floor + NETGEAR wn3000rpv3 wifi repeater for dead zones
==> 20mbps for dead zones with NETGEAR repeater, and 240 mbps for using 2nd floor wifi

but I have this extra D-LINK DIR866L from optimum cable which I don’t use (because i replaced it with LINKSYS MR9000 AC3000)
(and can also exchange it to SAGEMCOM optimum router anytime for free, Sagemcom is supposed to faster than DLINK DIR866L)

so 1st and 3rd floor are using wifi extender (UNWIRED) and leeching off of 2nd floor signal, pretty much
and this has not been too stable, so,
I am trying to WIRE everything (with ethernet cable) and use the extenders AS WIRELESS ACCESS POINTS (WAP)

SAGEMCOM or D-LINK DIR866L router as the 1st floor WAP
and LINKSYS RE6300 AC 1200 as the 3rd floor WAP

and obviously these will be both WIRED with CAT 7 ethernet cable from 2nd floor main router
(or should I connect it straight from the modem?)

How does this sound?
at the end of the day, it will be like

3rd floor: using wifi off of 2nd floor + LINKSYS RE6300 AC1200 WIRED to main modem/router from 2nd floor
2nd floor: MAIN MODEM and ROUTER (Linksys mr9000 AC3000)
1st floor: using wifi off of 2nd floor + SAGEMCOM or D-LINK router WIRED to main modem/router from 2nd floor

does this sound plausible?
or would it deteriorate the whole signal power for the entire building?

Usually WAPs are better than Wifi Repeater/extenders, no?

Please help me out, thanks!!

Turn Android device into a wireless or USB webcam with background removal

There exist several applications such as DroidCam that can turn one’s Android device into a wireless or USB webcam.

Do any of these applications have a background removal feature (= only shows the human face/upper body that appears on the video)? I tried DroidCam but it doesn’t seem to have this feature.

My specific TpLink Realtek USB Wireless Adapter in Ubuntu 20.04 LTS is suddenly not working anymore. Why?

This morning, I was able to make the USB Wireless Adapter work. It was working fine all day, until I decided to reboot my desktop tonight. All the sudden, the wireless adapter wasn’t doing its job and I have no idea why because I just rebooted. The wireless adapter stopped working after I rebooted.

Here’s more information of the USB: https://deviwiki.com/wiki/TP-LINK_Archer_T4U_v3

ID: 2357:0115

WI1 chip1: Realtek RTL8812BU

Here is the github I used to make the wireless adapter work: https://github.com/fastoe/RTL8812BU

I manually installed it again, rebooted, etc, still didn’t work. No errors occurred.

I make sure it was plugged in, the wireless adapter worked on my Windows but not the Ubuntu.

Why did it suddenly not work anymore?

How would I install / use my specific TpLink Realtek USB Wireless Adapter into Ubuntu 20.04 LTS without internet connection?

I use a TpLink Archer, it’s a Realtek, and I want to use it / install it into my Ubuntu. I have 2 drives, the first drive (C:) is Windows, which the USB Wireless Adapter works fine there, I just need it to work on my Ubuntu (D:) drive. My Ubuntu version is 20.04 LTS.

How can I install this into my Ubuntu? I am having trouble, and I’ve been searching everywhere but couldn’t find a solution.

No wireless options are found Ubuntu 20.04

I have recently installed Ubuntu 20.04. My previous distribution was Ubuntu 17.10. There was an issue where in my wifi settings it showed a message like this “No wifi adapters found”. So I asked about it in this community and people suggested me to install Ubuntu 20.04. So I installed it. But I don’t see any wifi options when I installed this. I searched through this issue but nothing is working. I am providing some command outputs if that helps.

What should I do now? People have suggested me that it could be a hardware problem. I want to be sure if I take this laptop to a mechanic. My laptop model is Asus X441U.

wireless – Headset microphone connected, but not producing sound

I have a wireless headset that I want to use both for sound and as microphone. However, when connecting it to the computer and selecting “Headset Head Unit (HSP/HFP)” in stead of “High Fidelity Playback (A2DP Sink)”, the computer does see the headset microphone, but no sound is registered. The headset does work as supposed to when connected to my phone, so it should not be a hardware problem in the headset microphone itself.

I have looked at the settings in alsamixer, but those don’t make sense to me. Additionally, all settings in pavucontrol and the system audio settings seem to be in the right place.

The microphone of my laptop is of such bad quality (very tinny sound with insane background noise), that I am now almost resolved to use my phone for video meetings. I would love to get the headset working properly.

networking – Can someone help me make my Ralink RT3290 Wireless card work properly on Ubuntu 20.04?

I have just installed Ubuntu 20.04 on my HP Envy laptop and Wifi connection is terrible: when it works it is very slow and sometimes it does not work at all. No issue on Windows 10.

Here is some info:

sirfabel@bellaplx01:~$ uname -a
Linux bellaplx01 5.4.0-47-generic #51-Ubuntu SMP Fri Sep 4 19:50:52 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

It seems only rt28xx cards are supported:

sirfabel@bellaplx01:~$ lsmod | grep rt

Apparently this is a well-known issue, according to what I saw on the web… I tried to apply some patches I found on some forums, but none of them worked…

Can please someone help me?

Thanks!

wireless – Ubuntu 20.04 No WIFI

A few days ago my ubuntu worked well, but today I can not find wifi in settings.

CHIPSET: ASUS X570
NETWORK CONTROLLER: INTEL AX200

By typing in lspci -v in the command line, I can see the network controller information in return.

I have installed the package backport-iwlwifi-dkms.

Reboot has been tried for several times.

Hope you guys could help me solve this issue.
