AT&T USA | Internet not working | Fix by custom APN

If the AT&T Mobile internet is not working on your cellphone, it can be fixed easily by adding an APN configuration.

You can read this at my Reddit as well.

Go to Settings -> Connections -> Mobile networks -> Access Point Names; Edit an existing APN configuration or create a new one. Save and activate.

An iPhone settings is mostly at

Settings > Cellular > Cellular Data Options > Cellular Network
OR
Settings > Mobile Data > Mobile Data Options > Mobile Data Network.

The config given below worked pretty well on my Samsung Galaxy S10 5G device. It gives around 4.3 mbps download and 1.2 mbps upload.

Use your stand-by Android or iPhone as Webcam and connect from Linux, Windows or Mac PC

Note: This content is available for read at my Reddit as well.

As the COVID lock-down continues and more people have adopted Work from Home option, the Webcams are running out of stock and the manufacturers are busy selling them at higher prices.

Here's a an easy alternative to use a stand-by Android or iPhone as Webcam using the Phone App and connect from Linux, Windows or Mac PC  using the client software.

I've been looking at DroidCam and iriun webcam as the options. The latter did well in Video resolution, auto-focus and picture quality. However, DroidCam overtook it with lots of desirable features though the video resolution is limited to 720p. You can set it to higher resolution in Linux client by editing /etc/modprobe.d/droidcam.conf.
Example: options v4l2loopback_dc width=1920 height=1080
Hence, DroidCam is the obvious winner.

The Pro version of both these come at around $5. The download links and installation documents are available at dev47apps.com and iriun.com respectively. Let's have a look at the Pros and Cons
