Slow Home Wi-Fi? Fixes to Try Before You Upgrade Your Plan

“I’m paying for 100 Mbps, but YouTube buffers in my bedroom.” I’ve heard this from at least half my friends. Usually, the next step is calling the broadband company to upgrade to a bigger plan.

But in my experience, the plan is rarely the problem. The problem is usually where the router sits, which Wi-Fi band you’re on, or the walls between you and the router. Most of these fixes are free. Let’s try them first.

Step 1: Figure Out Whether It’s the Internet or the Wi-Fi

These are two different things:

• Internet connection = the line coming into your home from your provider (JioFiber, Airtel Xstream, ACT, BSNL, local cable operator).
• Wi-Fi = the wireless signal your router creates inside your home.

A simple test:

1. Stand right next to your router with your phone and run a speed test on Speedtest by Ookla or Fast.com.
2. Then go to the room where Wi-Fi feels slow and run the test again.
3. If possible, connect a laptop to the router with an Ethernet cable and test.

What it tells you:

• Slow even next to the router or on cable → the problem is likely the internet line or your provider. Call them.
• Fast near the router, slow in other rooms → it’s a Wi-Fi coverage problem. Keep reading – that’s what we can fix ourselves.

Step 2: Restart Properly (Yes, Really)

I know, I know. But routers do get stuck, especially after power cuts or running for weeks.

1. Switch off the router (and the ONT/modem box if you have a separate one) at the plug.
2. Wait about 30 seconds.
3. Switch on the modem/ONT first, wait for its lights to settle, then the router.

If you find yourself doing this often, many routers have a scheduled reboot option in their settings. Setting it for 4 AM once a week is a nice trick.

Step 3: Move the Router (The Biggest Free Fix)

Wi-Fi signals hate walls, especially the thick concrete and brick walls common in Indian homes. They also hate metal, mirrors, water (fish tanks!) and being stuffed inside cabinets.

Where most routers end up: wherever the technician drilled the cable in – often a corner near the main door, or inside a TV unit. Not ideal.

Better placement:

• Central location in your home, as much as possible.
• Up high – on a shelf or wall-mounted, not on the floor.
• Out in the open – not inside a cupboard or behind the TV.
• Away from microwave ovens, cordless phones, and big metal objects like fridges and steel almirahs.
• Antennas (if your router has them): try one vertical and one horizontal. It sometimes helps devices on different floors.

If the cable can’t reach a central spot, ask your provider about extending it, or consider a mesh system (Step 7).

Step 4: Understand 2.4GHz vs 5GHz

Most modern routers broadcast two networks, sometimes with names like MyWiFi and MyWiFi_5G.

• 2.4GHz: travels farther and through walls better, but slower and more crowded (your neighbours’ routers, Bluetooth and microwaves use it too).
• 5GHz: much faster, less crowded, but weaker range and struggles with walls.

What to do:

• Same room or next room as the router? Use 5GHz. You’ll often see a big speed jump.
• Far rooms or a different floor? 2.4GHz might actually be more stable.
• Smart TV, laptop and phone near the router? Put them on 5GHz.
• Smart plugs, cameras, older devices? These often work only on 2.4GHz – that’s fine.

Some routers combine both into one network name (called band steering) and pick automatically. If yours does this and you have trouble, you can sometimes split them in the router settings.

Step 5: Change the Wi-Fi Channel

In apartment buildings, dozens of routers are fighting over the same channels. It’s like everyone talking at once at a wedding.

1. Install a Wi-Fi analyser app on your Android phone (search “Wi-Fi analyzer” on the Play Store – pick one with good reviews and minimal permissions).
2. See which channels are crowded.
3. Log into your router’s settings – usually by typing an address like 192.168.1.1 or 192.168.0.1 in your browser. The exact address and login are usually printed on a sticker on the router. JioFiber and Airtel also let you manage some settings from the MyJio or Airtel Thanks app.
4. Under Wireless or Wi-Fi settings, change the channel to a less crowded one, or set it to Auto.

For 2.4GHz, channels 1, 6 and 11 are commonly recommended because they don’t overlap. For 5GHz, there are more options.

Not comfortable changing router settings? Ask your provider’s technician to do it during a service visit.

Step 6: Check What’s Eating Your Bandwidth

Sometimes the Wi-Fi is fine – it’s just busy.

• Someone downloading a big game update on the PS5.
• A laptop backing up to Google Drive or OneDrive.
• Multiple 4K streams on different TVs.
• CCTV cameras uploading constantly.

Your router’s admin page (or the provider’s app) usually shows connected devices. If you see a device you don’t recognise, someone might be using your Wi-Fi. Change your Wi-Fi password and use WPA2 or WPA3 security.

Also: change the default router password (the one for the admin page, not just the Wi-Fi). Leaving it as “admin” is a common security hole.

Step 7: Extenders vs Mesh – When You Need Extra Hardware

If your home is large, has multiple floors, or has very thick walls, one router may never cover it all. Two options:

Wi-Fi extenders (repeaters)

Cheap and easy. Plug one in halfway between the router and the dead zone. It repeats the signal.

Downside: speed through an extender is often lower, and you may get a separate network name to switch between.

Mesh Wi-Fi systems

Two or three units that work together to create one network across your home. Your phone moves between them automatically.

Downside: more expensive than extenders. But for multi-floor homes or independent houses, it’s often worth it.

Tip: some providers rent or sell mesh units with their plans. Ask before buying separately.

Step 8: Update Firmware and Check Your Router’s Age

• Firmware updates fix bugs and improve stability. Check the router’s admin page for an update option. Provider-supplied routers often update automatically.
• Old routers (very old Wi-Fi standards) can bottleneck newer plans. If your router is many years old and you’re paying for a fast plan, ask your provider whether they’ll replace it with a newer model.

Step 9: Device-Side Fixes

Sometimes the problem is the device, not the Wi-Fi.

• Forget and reconnect the network on your phone.
• Turn off battery saver – it sometimes limits Wi-Fi performance.
• Update your phone/laptop software.
• On Windows laptops, update the Wi-Fi driver from the laptop manufacturer’s website.
• Check for VPNs – they can slow things down a lot.

When Upgrading Your Plan Actually Makes Sense

After trying the fixes above, consider upgrading if:

• Speed is slow even on a cable connection at the router.
• Many people work or study from home simultaneously, with video calls.
• You regularly download huge files or stream on multiple TVs at the same time.

And before upgrading, ask your provider:
– Is the router included in the upgrade capable of the new speed?
– Is there a fair usage policy or data cap?
– Can you try it for a month without a lock-in?

FAQ

Why is my Wi-Fi fast near the router but slow in other rooms?
Walls, distance and interference weaken Wi-Fi signals. Move the router to a central spot, or use 2.4GHz for far rooms or add a mesh system.

Should I use 2.4GHz or 5GHz?
5GHz for speed when you’re close to the router; 2.4GHz for better range through walls.

Do Wi-Fi extenders really help?
They can fix dead zones cheaply, but usually at lower speeds. Mesh systems work better for larger homes.

How do I know if someone is stealing my Wi-Fi?
Check connected devices in your router’s admin page or your provider’s app. Change your Wi-Fi password if you see unknown devices.
