Why does macOS WiFi keep dropping or not connecting?
Short answer: Most macOS Wi-Fi problems in India are caused by router channel congestion (2.4 GHz channels 1–6 are heavily overloaded in Indian apartment buildings), corrupted macOS network preferences that need an NVRAM reset, or AirDrop creating a Wi-Fi Direct channel that conflicts with the main connection on pre-2020 MacBooks. Hardware failure of the Wi-Fi card is rare and presents a distinct signature — the card vanishes entirely from System Information. Follow these steps in order before concluding it is a hardware problem.
How to fix macOS WiFi connection issues in India
Step 1: Fix your router's channel — the Indian-specific root cause
India has a unique Wi-Fi congestion problem. Most ISP-provided routers (JioFiber, Airtel, BSNL) default to the 2.4 GHz band on automatic channel selection. In a typical Indian apartment building, 20–40 routers are running within range of each other, most sitting on channels 1, 6, or 11. The 2.4 GHz band has only three non-overlapping channels — it saturates quickly.
The fix: log into your router admin panel (usually 192.168.1.1 or 192.168.0.1 in a browser). Switch your MacBook's network to the 5 GHz band if your router supports it (most dual-band routers sold since 2018 do). Set the 5 GHz channel to a fixed value — channels 36, 40, 44, or 48 are typically uncongested in India. The MacBook will connect to this band and hold the connection far more reliably.
If your router only supports 2.4 GHz, manually set the channel to 1 or 11 (avoid channel 6 — it is the most congested in Indian cities) and set the channel width to 20 MHz instead of 40 MHz for better interference rejection in dense environments.
Step 2: Disable AirDrop when not using it
AirDrop (Apple's peer-to-peer file-sharing feature) uses Bluetooth to discover nearby Apple devices and then creates a temporary Wi-Fi Direct (peer-to-peer Wi-Fi without a router) channel to transfer files. On MacBooks from 2015–2019, this Wi-Fi Direct channel can interfere with the main Wi-Fi connection, causing drops or speed degradation while AirDrop is discoverable.
To check: open Control Centre from the menu bar, click AirDrop, and set it to "No One" or "Contacts Only" instead of "Everyone". If your Wi-Fi suddenly becomes stable after doing this, AirDrop interference was the cause. Also read our macOS update issues fix guide — macOS updates sometimes re-enable AirDrop to "Everyone" silently.
Step 3: Reset NVRAM and delete network preferences
NVRAM (Non-Volatile RAM — a small dedicated memory chip in every Mac that stores Wi-Fi preferences, display settings, and startup disk choice even when the Mac is powered off) can store corrupted data. Corrupted Wi-Fi preferences cause the Mac to try to connect to networks it knows about but fail silently, or to refuse DHCP (Dynamic Host Configuration Protocol — the system your router uses to automatically assign an IP address) assignments.
NVRAM reset on Intel MacBooks (2020 and earlier): Shut down the Mac. Power it on and immediately hold Command ⌘ + Option ⌥ + P + R together for 20 seconds. Release the keys. The Mac restarts with NVRAM cleared.
M-series MacBooks (M1/M2/M3/M4 — 2020 onwards): NVRAM resets automatically every time the Mac starts cleanly. Just restart normally.
After the NVRAM reset, also delete the stored Wi-Fi network list: go to System Settings → Wi-Fi → click the ⋯ button next to your network → Forget This Network. Then reconnect fresh. This clears any corrupted DHCP lease or authentication credentials.
Step 4: India angle — how to tell when it is hardware, not software
The question we get most from Indian MacBook users: "Is this a hardware problem or a software problem?" Here is the definitive test. Click the Apple menu → About This Mac → System Report → Network → Wi-Fi. If you see your Wi-Fi card listed with a name (usually "Broadcom 802.11..." or "Apple BCM..." on Intel Macs, or "Apple Wi-Fi" on M-series), the hardware is fine and the issue is software. If the Wi-Fi entry shows "No information found" or is absent entirely, the hardware card has failed.
Hardware Wi-Fi failure on MacBooks in India is most often caused by liquid damage, physical shock, or oxidation of the Wi-Fi antenna connector — the latter is accelerated by India's coastal humidity in cities like Mumbai, Chennai, Kochi, and Visakhapatnam.
If you have worked through Steps 1–3 and the issue persists, and the Wi-Fi card still shows in System Report, try creating a new macOS user account (Apple menu → System Settings → Users & Groups → Add Account). Log into the new account and test Wi-Fi. If it works in the new account but not your main account, the issue is a corrupted user-level network preference — a support technician can fix this in under an hour.

When to call a laptop repair service (and what it costs in India)
When DIY ends
Call a technician if: the Wi-Fi card does not appear in System Report at all; the Mac was recently exposed to moisture or dropped; Wi-Fi does not work even with a factory macOS reinstall; or the issue is limited to one MacBook while all other devices on the same network work fine (the router is not the cause).
Typical repair cost in India
Software-level Wi-Fi fix (preference reset, new network location, user account repair): ₹500–₹1,200. Wi-Fi card replacement on Intel MacBook: ₹3,500–₹8,000 depending on model. Liquid damage clean + Wi-Fi card repair: ₹4,000–₹12,000 — though this is better diagnosed first, as it sometimes also affects the logic board.
A note from the LRW Engineer Team
The router-channel fix (Step 1) resolves the majority of MacBook Wi-Fi complaints we hear from customers in Indian apartment buildings. It takes five minutes, costs nothing, and every Apple device in the home benefits. Before bringing in the MacBook, log into your router and try the 5 GHz band switch first.
