[Fire HD 8 and HD 10 General] DragonFire1024:
Even with my framework-res mods and FireTabletSettings.apk, These tablets just don't want to cooperate with us and we still have issues with the connections dropping out for no apparent reason, but much less of them. In Android, there has always been the ability to modify individual WiFi connections. FireOS is not different. This guide will show you how to optimize your individual WiFi connections wherever you go for almost any connection. Best of all, this does NOT require root access to the device or installing any modified APKs.

FIRST OPTION:

REQUIREMENTS:

1. Unrooted (Works on rooted too) Fire 7, HD 8, HD 10 (any year or model).

2. Windows PC (If you know how to look up IP configurations on a Mac, this may work too).

INSTRUCTIONS:

1. On your PC, click on the start button (usually lower left corner of screen).

2. In the box where it says "search programs and files" type: CMD then press enter. A Windows command line window will open.

3. In the CMD window, type the following: ipconfig

4. Several sections will appear. Depending on your connection type (WiFi, ethernet etc) is how we choose what configuration to use. In my case, I am using a 'Wireless LAN (Local Area Network) Adapter' with Wireless Network Connection so we will use that configuration.

5. Leave that window open on your PC and grab your tablet. Connected to WiFi, Tap: settings > wireless > Wi-Fi > 3 dots at upper right corner > advanced. Take note of the numerical IP address and write it down.

6. Go back to your WiFi connections screen. Long press the network you are connected to and tap 'forget.'

7. Tap on the WiFi connection you were just on want to connect to. Enter the password but do NOT tap connect.

7. Tap or check the box of 'advanced options' and select proxy as NONE and IP settings as STATIC. Back on your PC, go to the ipconfig window we opened earlier.

8. From the ipconfig window, you want to enter the following corresponding information, like the screenshot below.

9. On your PC you need the following information to go into the advanced settings on your tablet like so:

Tablet: IP address = IP address you copied down earlier in the advanced WiFi options of your tablet

Tablet: Gateway = Default Gateway in your ipconfig window on PC (use the standard IP form. Example: 10.0.0.1)

Tablet: Network Prefix Length: 24

Tablet: DNS 1: 8.8.8.8 for Google or 1.1.1.1 for Cloudfare

Tablet: DNS 2: 8.8.4.4 for Google or 1.0.0.1 for Cloudfare

10. Now you can tap connect.

This may not work for WiFi connections like 'xfinity' hot spots or any other major carrier hot spots. As long as you connect to a physical router and have access to the IP configuration, you can modify any of your network connections for the best WiFi optimization. NOTE: the DNS settings saved in your connection will override any DNS settings you have in your build.prop.

To undo the above configuration, long press the connected network, tap forget.

SECOND OPTION:

1. Download rooted activity launcher https://github.com/DerekZiemba/RootActivityLauncher

2. Open activity launcher and scroll to settings and tap it. Scroll until you see date and time settings (there are two). Tap the first one and disable automatic time zone. Tap the second one and disable automatic time zone.

3. This option doesn't require a reboot and the results are nearly instant.
