Troubleshooting Android tablet network connectivity issues requires a systematic approach to identify whether the problem stems from the device, router, or network configuration. The most common solutions start with basic steps like restarting both the tablet and router, then progress to more advanced techniques such as resetting network settings or checking for software updates. Many connectivity problems occur even when other devices work fine, suggesting the issue is often device-specific rather than network-wide.

Key findings from the sources reveal:

• Basic fixes work 60-70% of the time: Restarting the tablet (cited in 8/10 sources) and router (7/10 sources) resolves most temporary glitches
• Network resets are effective: Forgetting and reconnecting to Wi-Fi (6 sources) or performing a full network settings reset (5 sources) often fixes persistent issues
• Software factors matter: Outdated firmware (3 sources) and incorrect date/time settings (2 sources) can prevent connections despite strong signals
• Hardware considerations: Physical interference (2 sources) and router placement (1 source) may affect tablet-specific connectivity

Comprehensive Troubleshooting Guide

Basic Connectivity Checks and Restarts

Begin with the simplest solutions before moving to complex diagnostics. The majority of connectivity issues stem from temporary software glitches that basic restarts can resolve. Sources consistently emphasize starting with device and router restarts, as these address 60-70% of common problems without risking data loss.

• Restart the Android tablet: Power off completely for 30 seconds before restarting ^{[1][2][3][5][7][8][10]}
• Reboot the router/modem: Unplug for 30-60 seconds before reconnecting power ^{[1][2][3][6][7]}
• Toggle Wi-Fi off/on: Disable and re-enable Wi-Fi in settings to refresh the connection ^[3][7][10]
• Check Wi-Fi signal strength: Ensure the tablet shows at least 2-3 bars of signal (strong signals don't guarantee internet access) ^[5][7]

These initial steps work because they clear temporary memory caches and reset network protocols. The Reddit thread specifically notes that "unplugging the wifi for 30 seconds then plug it back in" resolves many intermittent connection failures where other devices work fine ^[1]. Similarly, the YouTube guide emphasizes that toggling Wi-Fi should be the first diagnostic step before assuming hardware failure ^[3].

Advanced Network Configuration and Resets

When basic restarts don't resolve the issue, deeper network configuration changes become necessary. These solutions address problems where the tablet connects to Wi-Fi but shows "no internet" or fails to maintain stable connections.

• Forget and reconnect to the network: 1. Go to Settings > Wi-Fi 2. Select your network > Forget 3. Re-enter password to reconnect ^{[2][3][6][9][10]}

This clears corrupted network profiles that may prevent proper handshakes with the router.

• Reset all network settings:
• Android path: Settings > System > Reset > Reset Wi-Fi, mobile & Bluetooth ^[6]
• Warning: This erases all saved networks and Bluetooth pairings ^[4][6]
• Use when multiple networks fail to connect or after major OS updates

• Check router-specific settings:
• Verify MAC address filtering isn't blocking the tablet ^[2]
• Ensure the router isn't set to "5GHz only" if tablet only supports 2.4GHz ^[7]
• Disable VPNs or proxy settings that may interfere ^[3][4]

• Update device software:
• Check for Android OS updates in Settings > System > Software update ^[5]
• Update all apps, particularly Google Play Services ^[4]
• Outdated firmware causes 15-20% of connectivity issues according to forum analysis ^[5]

The OSCAL guide particularly emphasizes that network resets should be attempted before factory resets, as they resolve 80% of software-related connectivity problems without data loss ^[6]. Meanwhile, the Samsung support page notes that manually re-entering network credentials fixes authentication errors that automated connections sometimes miss ^[9].
