Can You Upgrade Your Laptop’s Wi-Fi Card? Compatibility Checks

Not every laptop’s Wi-Fi card can be upgraded. Some are soldered permanently to the motherboard, while others use replaceable M.2 slots. If you’ve got a slow Wi-Fi card or outdated Wi-Fi 5, your first question should be: is my laptop even upgradeable? This guide walks you through the exact steps to determine if your specific laptop supports Wi-Fi card upgrades and what your realistic options are if it doesn’t.

Soldered vs. Replaceable: The First Check

This is the critical distinction. If your laptop’s Wi-Fi module is soldered to the motherboard, upgrading is impossible. If it uses an M.2 socket, you can swap cards in seconds.

What Are Soldered Components?

Soldered means the Wi-Fi chip is directly attached to the motherboard with solder joints. This makes ultra-thin laptops possible (thinner than 15mm) but impossible to upgrade. Removing a soldered component requires a microscope, heat gun, and professional-level electronics skills. It’s not a practical DIY task.

Which Laptops Have Soldered Wi-Fi?

Most ultra-thin and premium models:

• All MacBooks (soldered—no upgrades possible)
• ASUS ZenBook (many models, especially OLED variants)
• Dell XPS 13 (some 2021+ models with compact design)
• HP Spectre x360 (many models)
• Budget laptops under £300 (manufacturers cut costs by soldering)

Usually replaceable (M.2 slots):

• Lenovo ThinkPad (all models)
• Business laptops (Dell Latitude, HP ProBook, HP EliteBook)
• Gaming laptops (ASUS ROG, MSI, Razer)
• Most consumer laptops over £600
• Older laptops (2017 and earlier)

How to Check If Your Laptop Is Upgradeable

Method 1: Download the Service Manual (Best)

The fastest and most reliable way to determine upgradeability is your laptop’s official service manual.

1. Find your exact model number. On Windows, open Settings → System → About. Look for “Model” or “Product Name.” On Mac, click Apple menu → About This Mac → System Report and note the “Model Identifier” and “Model Name”.
2. Visit the manufacturer’s support page. Dell, HP, Lenovo, and ASUS all have support sites where you can search by model.
3. Download the service manual PDF. Search for “service manual,” “maintenance guide,” or “hardware manual.”
4. Search the PDF for “Wi-Fi” or “wireless.” If you see instructions like “Remove Wi-Fi card” with photos showing an M.2 slot, your card is replaceable. If there’s no removal section, it’s likely soldered.
5. Look for “M.2” or “Key A+E / E”. This confirms a removable slot.

Most manufacturers provide free PDFs. If you can’t find yours, try searching “[laptop brand] [exact model number] PDF filetype:pdf” on Google.

Method 2: Physical Inspection

If you can’t find the service manual, you can physically open your laptop to check. Do this carefully—you risk damaging components.

1. Power off the laptop completely and unplug it.
2. Let it cool for 5 minutes.
3. Remove the bottom panel. Usually 4–8 Phillips screws hold it on. Unscrew these and carefully pry the panel up (don’t force it—look for hidden clips).
4. Look inside the case. Find the Wi-Fi module—it’s a small rectangular board, roughly 50mm × 30mm, with a connector on one end. It’s usually located along one edge of the motherboard.
5. If you see a small slot with a golden connector on the motherboard, and the card is plugged into it, it’s replaceable (M.2). If the card appears to be directly glued or soldered to the motherboard with no visible connector, it’s soldered.
6. Close the panel and reassemble. Replace the screws.

If you’re not comfortable opening your laptop, take it to a computer repair shop. They can check upgradeability in 5 minutes for free or a small fee.

Method 3: Online Research

Search your exact laptop model on Reddit, forums, or YouTube. Users often discuss upgradeability. Search “[laptop brand] [model] Wi-Fi upgrade” or “[brand] [model] removable Wi-Fi card.” Community forums like NotebookCheck or TechSpot often have detailed upgrade guides for popular models.

Method 4: Contact the Manufacturer

As a last resort, email the manufacturer’s support with your model number and ask: “Is the Wi-Fi card in my [model] removable or soldered?” They should provide a direct answer.

Checking for Antenna Requirements

Even if your Wi-Fi card is replaceable, your laptop must have antenna cables to connect to the new card. Some ultra-thin laptops skip antenna installation to save space, leaving you with a replaceable card slot but no way to connect antennas to a new card.

How to Check Antenna Availability

In the service manual: Look for “antenna” or “RF cable.” If photos show antenna cables routed through your laptop, you’re good.

Physical inspection: When you open the bottom panel, look for two small coaxial cables (thin, shielded cables with connectors on the ends) running along the sides or back of the laptop, near the Wi-Fi slot. If you see at least one cable, you can upgrade. If the slot is empty with no cables, you cannot.

Single vs. Dual Antenna

Most Wi-Fi cards today are 2×2 MIMO (two antennas for better performance). If your laptop has only one antenna cable, you can install a 2×2 card, but you’ll only get 1×1 performance. If you have two cables, you’ll get full 2×2 performance. Ideally, count the cables before upgrading and buy a card matching your antenna count.

Brand-by-Brand Upgradeability Overview

Red Flags: Laptops NOT Upgradeable

If your laptop has any of these characteristics, Wi-Fi upgrades are likely impossible:

• Ultra-thin design (under 13mm thick): MacBook Air, most ZenBooks, Spectre x360. These sacrifice upgradeability for thinness.
• All-in-one or integrated design: Some compact business laptops have everything soldered for durability and compactness.
• Budget price (under £300): Cheap laptops often solder components to cut manufacturing costs.
• Mentions of “no user-serviceable parts”: If the warranty mentions this, upgrades are likely impossible.
• 2023+ MacBooks or newest iPad Pro: All soldered as of 2023.

If Your Laptop Is NOT Upgradeable: Your Options

Option 1: USB Wi-Fi Adapter

Cost: £25–60

Pros: Works with any laptop (including MacBooks). No warranty risk. Easy plug-and-play installation.

Cons: Takes up a USB port. Adds a dongle to your setup. Slightly slower than internal cards.

Best for: MacBook users, travelers, people who need flexibility. Shop for USB Wi-Fi adapters on Amazon UK. For more details, see our USB Wi-Fi adapter guide.

Option 2: Ethernet Dongle

Cost: £20–40

Pros: Faster than Wi-Fi (if your ISP supports gigabit). More stable. Shop for Ethernet adapters on Amazon UK

Cons: Requires a wired connection. Not mobile.

Best for: Home office setup with a nearby router or modem.

Option 3: Better Router

Cost: £100–300

Pros: Improves Wi-Fi for all devices in your home, not just your laptop. Solves congestion issues.

Cons: Requires home network upgrade (not portable). Doesn’t help if the problem is your laptop’s card.

Best for: If you’re experiencing slow Wi-Fi across multiple devices. A Wi-Fi 6 router can work wonders for older laptops.

Option 4: Accept It and Upgrade Later

Cost: £0 now (upgrade later)

Pros: No immediate expense.

Cons: You’re stuck with slow Wi-Fi until you replace the laptop.

Best for: If your laptop is old anyway, saving for a replacement makes more sense than buying a USB adapter now.

Age Matters: Older Laptops Are Usually Upgradeable

If your laptop is from 2018 or earlier, it’s very likely upgradeable. As laptops got thinner (2018–2023), manufacturers increasingly soldered components. Here’s a rough guide:

• 2015–2017 laptops: ~95% have upgradeable Wi-Fi cards
• 2018–2020 laptops: ~70% have upgradeable Wi-Fi cards
• 2021–2023 laptops: ~50% have upgradeable Wi-Fi cards (ultra-thin = soldered)
• 2024+ laptops: Soldering is increasingly common; always check the service manual

This is why older laptops are often worth upgrading—you’re more likely to have the option.

The BIOS Whitelist Factor

Even if your laptop has a removable Wi-Fi card slot, some manufacturers enforce BIOS whitelists that block non-approved cards. This is a software restriction that can prevent even physically compatible cards from working.

See our BIOS whitelist guide for details. For now, know that:

• Removable slot ≠ guaranteed upgrade
• Check your brand’s reputation for BIOS restrictions (Dell strict, ASUS permissive)
• Whitelists can sometimes be bypassed via BIOS updates or modded BIOS (advanced users only)

Step-by-Step: Determining if YOU Can Upgrade

1. Get your exact model number. Settings → System → About on Windows. Apple menu → About This Mac on Mac.
2. Search for the service manual. Visit [brand] support page and search your model.
3. Download the PDF. Save it locally and open with a PDF reader.
4. Search for “Wi-Fi” or “wireless”. Ctrl+F on Windows, Cmd+F on Mac.
5. Look for removal/disassembly instructions. If photos show removing an M.2 card, you’re upgradeable.
6. Check for antenna cables. The manual should show antenna routing.
7. Note the BIOS whitelist policy. Some manuals mention this. If not, search online for “[brand] [model] BIOS whitelist Wi-Fi upgrade.”
8. If manual not found or unclear, open the laptop and physically inspect (or visit a repair shop).
9. Once confirmed, research compatible cards for your exact model. See our brand-specific guides (Dell, HP, Lenovo, ASUS).

Frequently Asked Questions

My laptop’s Wi-Fi is slow. Does that mean it’s not upgradeable?

No. Slow Wi-Fi is usually due to an older Wi-Fi standard (Wi-Fi 5 vs. Wi-Fi 6) or a congested network. Even if your card is soldered, upgrading your router might help. If your card is removable and it’s Wi-Fi 5, upgrading to Wi-Fi 6 will likely speed things up.

How do I know if my laptop has Wi-Fi 5 or Wi-Fi 6?

On Windows: Settings → Network & internet → Wi-Fi → Advanced options. On Mac: System Settings → Wi-Fi. Look for “Wi-Fi generation” or run a CPU-Z-style app to identify your card. Or just download your service manual and search for the Wi-Fi card model.

What if I open the laptop and the Wi-Fi card is glued down?

It’s soldered or glued—not meant to be removed. Close it back up carefully and don’t try to force removal. You’ll damage the motherboard. Use a USB Wi-Fi adapter instead.

Is opening my laptop to check upgradeability legal?

Yes. The US Right to Repair movement and UK consumer law protect your right to open devices you own. However, opening the laptop may void your warranty if you break something. Be careful and consider visiting a repair shop instead.

My laptop is under warranty. Can I still upgrade?

Opening your laptop may void the warranty, even if the upgrade is successful. Check your warranty document. For business laptops (ThinkPad, Latitude), manufacturers often tolerate user upgrades. For consumer devices, warranty may be forfeited. If your laptop is under warranty and Wi-Fi is faulty, contact the manufacturer for a free replacement instead.

If my laptop isn’t upgradeable, is it worth buying a USB Wi-Fi adapter?

Only if your Wi-Fi is truly problematic. For most people, the built-in card works fine. USB adapters add a dongle and take up a port. If you’re managing on the current Wi-Fi, don’t upgrade. If you need better range or speeds for gaming/video calls, it’s worth trying.

How long does it take to upgrade a Wi-Fi card?

15–30 minutes if you’re careful. Remove the bottom panel (2 min), disconnect antennas (2 min), remove the old card (1 min), insert the new card (1 min), reconnect antennas (2 min), reassemble (2 min). Don’t rush.

What if my service manual doesn’t mention Wi-Fi at all?

Try contacting the manufacturer or visiting a repair shop. If no documentation exists and the card is hard to find visually, it’s likely soldered. Budget £20 to have a shop verify for you.
