Why is your laptop WiFi not connecting?
Short answer: Laptop WiFi failures almost always fall into one of four buckets — a router stuck in a bad state after a power cut, a Windows driver update that replaced the wireless driver with a broken version, a 5 GHz band your laptop cannot reach through thick walls, or (rarely) a failed WiFi hardware module. Work through each in order before spending anything on hardware.
How to fix laptop WiFi not connecting
Step 1: Rule out the router — power-cut state is the most common culprit
Before touching the laptop at all, restart your router and modem. In India, frequent power cuts leave routers in a partial state — the router is on, broadcasts a network name, but has lost its WAN (internet) session with the ISP. The laptop connects to the local WiFi name but gets no internet, and it looks like a laptop problem.
Unplug your router from the wall for 30 seconds (not just the reset button — pull the power cable). Plug it back in. Wait 90 seconds for the DHCP lease — the process by which the router assigns an IP address to every device — to renew. Test again. If other phones and tablets now connect fine but your laptop still does not, the router is cleared and the fault is on the laptop side.
Also check whether the router changed its WiFi password after a reset to factory settings. Some ISP-provided routers in India reset to a printed-on-the-label default password when the firmware updates overnight. Try the password on the router label if your saved password stops working.
Step 2: Roll back or reinstall the WiFi driver
Windows 10 and 11 updates frequently replace manufacturer-tuned WiFi drivers with Microsoft's generic driver. The generic driver often works, but on Intel Wi-Fi 6 / Wi-Fi 6E cards (found in most laptops made from 2020 onward) it can cause intermittent drops or full failure to connect.
Open Device Manager (press Windows + X, then M). Expand Network Adapters. Right-click your wireless adapter — it will be named something like "Intel Wi-Fi 6 AX201" or "Realtek RTL8822CE". Choose Properties → Driver → Roll Back Driver. If Roll Back is greyed out, choose Update Driver → Browse my computer → Let me pick and select an older version from the list. Restart the laptop.
If no older driver is available, go to the laptop manufacturer's support page (HP Support, Dell Support, Lenovo Support, etc.), search by your model number, and download the latest WiFi driver directly. Manufacturer drivers are tested against your specific hardware and are almost always more stable than what Windows Update installs.
Step 3: Fix the network profile — forget and reconnect
Windows stores network profiles that can become corrupted, especially after a router firmware change or password update. Click the WiFi icon in the taskbar, find your network name, right-click it, and choose Forget. Then click the network again and enter the password fresh. This clears the corrupted profile and forces Windows to negotiate a new DHCP lease.
On Mac, go to System Settings → Wi-Fi → Details next to the network name, then click Forget This Network. On Apple Silicon MacBooks (M1, M2, M3, M4 chips), a corrupted network profile can also prevent the laptop from seeing 5 GHz networks. Forgetting and reconnecting usually fixes this without any driver update.
If you are still not connecting after a forget-reconnect, try creating a new network location on Mac: System Settings → Network → Location → Edit Locations → +. This resets all network settings to defaults for that location profile.
Step 4: The India angle — dual-band routers, concrete walls, and 5 GHz signal loss
Most modern routers sold in India — from brands like TP-Link, D-Link, and Jio — broadcast on both 2.4 GHz and 5 GHz bands. The 5 GHz band is faster but travels shorter distances and penetrates concrete walls poorly. Indian homes and offices built with thick RCC (reinforced concrete) slabs lose almost all 5 GHz signal beyond two rooms.
If your laptop connects from the same room as the router but fails from a bedroom or office two rooms away, the solution is not a hardware repair — it is band selection. Log in to your router's admin panel (usually 192.168.1.1 or 192.168.0.1) and either disable the 5 GHz band on the far network name or create a separate 2.4 GHz-only network for rooms far from the router. Your laptop will get a slower but more stable connection.
Also check the laptop's Power Management settings for the WiFi adapter: Device Manager → Network Adapters → right-click WiFi → Properties → Power Management → uncheck "Allow the computer to turn off this device to save power." Windows aggressively powers down WiFi in battery-save mode, causing random drops that look like a hardware problem.
When to stop and call a laptop repair service
When DIY ends
Stop and get the hardware checked if: the WiFi adapter does not appear in Device Manager at all, the adapter appears with a yellow warning triangle even after driver reinstall, the laptop shows no wireless networks even in the same room as the router, or you can see networks on your phone but not on the laptop from the same spot. These all point to a failed or loose WiFi module — a small M.2 card inside the laptop that may need reseating or replacement. Visit our laptop general service page for diagnostics.
Typical WiFi repair cost in India
Driver reinstall and network profile fix: free (software only). WiFi module reseating: ₹300–₹600 (labour). WiFi card replacement (Intel AX200/AX201 or similar): ₹800–₹2,500 depending on the card type. Antenna cable repair (if the thin wires running to the screen lid are damaged): ₹500–₹1,500. See our laptop webcam not working guide — WiFi and webcam issues share the same M.2 antenna path on many models.
A note from the LRW Engineer Team
The single most underrated WiFi fix we see is the power-management setting for the adapter. Windows 11 introduced more aggressive battery optimisation, and it cuts WiFi mid-session more often than any driver bug. If your WiFi drops every 10–15 minutes but reconnects on its own, check that setting before anything else. It takes 30 seconds and fixes the problem about half the time.
