Why is 5GHz Wi-Fi not showing up on your laptop?
Short answer: The three most common causes are: the Wi-Fi adapter is set to 2.4GHz Only in its driver settings, the router is broadcasting on a 5GHz channel above 100 that older cards cannot detect, or the laptop is simply too far from the router for 5GHz to reach it. Check these before assuming the Wi-Fi card is broken. True hardware Wi-Fi failures are far less common than these software/configuration issues.
How to fix 5GHz Wi-Fi not showing on laptop
Step 1: Confirm the adapter supports 5GHz
Open Command Prompt (Windows + R → cmd) and run: netsh wlan show drivers. Look for Radio types supported. If you see 802.11a, 802.11n, 802.11ac, or 802.11ax — the card supports 5GHz. If only 802.11b and 802.11g appear, the card is 2.4GHz only and cannot connect to 5GHz networks regardless of settings. On macOS, hold Option and click the Wi-Fi icon in the menu bar — it shows supported PHY modes including 802.11a/ac/ax.
Step 2: Check adapter band setting in Device Manager
Open Device Manager → Network adapters → right-click the Wi-Fi adapter → Properties → Advanced tab. Look for a setting named Preferred Band, 802.11n/ac/ax Band, or Wireless Mode. If it is set to 2.4GHz Only, change it to Auto or 5GHz Preferred. Click OK. Disconnect and reconnect Wi-Fi — the 5GHz network should now appear. Also check the 802.11a/b/g/n/ac setting and ensure 5GHz enabled is selected if present.
Step 3: Fix router channel for India
India's TRAI spectrum regulations restrict certain 5GHz channels (DFS channels above 48). Many routers in India set 5GHz to Auto channel and sometimes pick channel 100 or above — which older 802.11ac Wi-Fi cards (common in laptops from 2019–2022) may not detect. Log into your router admin panel (typically 192.168.1.1 or 192.168.0.1) and under 5GHz wireless settings, manually set the channel to 36, 40, 44, or 48. These are universally allowed in India and detected by all dual-band adapters.
Step 4: The India angle — mesh extenders and dual-band routers
Many Indian homes now use Wi-Fi mesh extenders (Tenda Nova, TP-Link Deco, Google Nest WiFi) which create a combined SSID for both 2.4GHz and 5GHz bands. On some older laptops, the combined SSID connection always lands on 2.4GHz because the adapter prefers the stronger signal. To force 5GHz: go to the mesh app settings and create a separate 5GHz SSID (e.g., Home_5G), then connect the laptop specifically to that SSID. Also update the Wi-Fi driver from the laptop manufacturer's support page — Intel and Realtek Wi-Fi drivers receive frequent improvements for band steering. For laptops where the Wi-Fi adapter stopped working entirely (not just 5GHz), see our Wi-Fi adapter not found fix guide and our Wi-Fi not connecting guide. Hardware Wi-Fi card replacement costs ₹1,200–₹3,000 if the card is physically faulty.
When to call a laptop repair service
When DIY ends
Seek professional help if: the adapter does not show up in Device Manager at all, Wi-Fi disappeared after a physical drop or liquid spill, or 5GHz is absent across multiple drivers and multiple routers.
Typical cost in India
Wi-Fi/Bluetooth combo card replacement: ₹1,200–₹3,000. Wi-Fi driver configuration and network setup: ₹300–₹600. Doorstep diagnosis: ₹149, No Fix No Fee.
A note from the LRW Engineer Team
The most overlooked 5GHz fix is simply moving the laptop 1–2 metres closer to the router. 5GHz signals attenuate significantly through walls compared to 2.4GHz. A laptop that shows only 2.4GHz networks from the bedroom but shows both bands in the living room next to the router — that is distance attenuation, not a hardware fault.
