### Wifi not connected

Configure a separate 2.4 GHz JioFiber network using WPA2-PSK (AES), remove the old JioFiber profile from Windows 7, and reconnect to the newly configured network.

1. Check the laptop’s supported Wi‑Fi bands

The working phone hotspot indicates that the wireless adapter is operational, but it may not support the band currently used by the Jio router. This exact Windows 7 symptom—phone hotspot works while home Wi‑Fi does not—can occur when the router uses 5 GHz and the older adapter supports only 2.4 GHz.^1^

1. Open Control Panel → Network and Internet → Network and Sharing Center.
2. Select Change adapter settings.
3. Right-click Wireless Network Connection → Properties → Configure → Advanced.
4. Look for Wireless Mode, Band, or a similarly named setting:
   • 802.11b/g or 802.11b/g/n indicates 2.4 GHz support.
   • If no 5 GHz mode is listed, use the router’s 2.4 GHz network.

2. Change the JioFiber Wi‑Fi compatibility settings

Jio routers are dual-band devices, so enable separate 2.4 GHz and 5 GHz Wi‑Fi names if that option is available.^2^

Using the Jio router administration interface or Jio management application:

1. Open the Wi‑Fi, Wireless, or SSID settings.
2. Ensure 2.4 GHz Wi‑Fi is enabled.
3. Give it a distinct name, such as Home_2.4G.
4. Set its security to:
   • WPA2-PSK
   • AES
5. Do not use WPA3-only for this Windows 7 laptop. WPA3 requires support from both Windows and the wireless adapter; Microsoft documents WPA3 support for newer Windows versions and compatible adapters, not Windows 7.^3^
6. Save the settings and allow the router to restart.
7. Confirm that Home_2.4G appears in the laptop’s available-network list.

Avoid WEP or WPA/TKIP as a compatibility workaround because those are outdated and insecure standards.^4^

3. Remove the old JioFiber profile from Windows 7

The saved profile can retain the router’s former security settings. Open Command Prompt as administrator and run:

netsh wlan show profiles
netsh wlan delete profile name="Your JioFiber Wi-Fi name"
netsh wlan show networks mode=bssid

Replace Your JioFiber Wi-Fi name with the exact profile name shown by the first command. The netsh wlan delete profile command removes the stored wireless profile.^5^

Then:

1. Click the network icon in the notification area.
2. Select the new 2.4 GHz network.
3. Click Connect.
4. Enter the WPA2 password again.

If it still does not connect

• Network name is absent: Ensure the router broadcasts its SSID and that 2.4 GHz is enabled. Trying the alternative frequency band is a documented connectivity check.^6^
• Network appears but authentication fails: Re-enter the password and confirm the router uses WPA2-PSK/AES, not WPA3-only.
• Other 2.4 GHz WPA2 networks also fail: Download the Windows 7 wireless driver from the laptop or Wi‑Fi adapter manufacturer and install it. Do not use an unrelated generic driver.
• Only this Jio network continues to fail: Back up or record the Jio router settings, then contact Jio support to check its firmware and compatibility configuration. A factory reset is a last resort because it erases customized router settings; a closely matching case was resolved by resetting the router, but that should only be attempted with the ISP’s setup details available.^7^

Windows 7 Ultimate is no longer supported; its extended support ended on January 14, 2020, and its final ESU period ended in January 2023.^8^ If the internal adapter cannot support the router’s compatible settings, use a USB Wi‑Fi adapter whose manufacturer explicitly provides Windows 7 drivers, or preferably upgrade to a supported Windows version and compatible hardware.
