Is it possible to install an SSD instead of Wi-Fi in a laptop? Pros, cons and step-by-step guide

You want to increase the storage capacity in your laptop, but only the slot for Wi-Fi module? Or yours M.2 connector is busy with the drive, and the wireless network is working through USB adapter? Replacement Wi-Fi on SSD - a non-standard, but quite feasible solution. However, before removing the module Intel AX200 or Qualcomm Atheros, it’s worth weighing the pros and cons.

In this article we will look at when such a replacement is justified, what technical nuances need to be taken into account (depending on slot type M.2 Key A/E to support NVMe), and how not to be left without the Internet after modernization. We will also tell you about alternatives - from PCIe splitters to external SSD boxes with support Wi-Fi 6.

When does it make sense to replace Wi-Fi with SSD?

The idea of sacrificing a wireless module for an additional storage device is relevant in three cases:

• 🔧 Your laptop has only one M.2 slot, already occupied by the SSD, and the HDD is missing (for example, in ultrabooks Dell XPS 13 or Lenovo Yoga).
• 💾 You are critically short of space, but Replacing the main SSD with a capacitive version (2–4 TB) is more expensive than buying a second drive + external Wi-Fi adapter.
• 📡 The wireless module is outdated (for example, Wi-Fi 4 on 802.11n), and replacing it with Wi-Fi 6E not practical due to price.

However, there is a downside: without built-in Wi-Fi you will lose:

• ⚡ Energy efficiency: External USB adapters (such as TP-Link Archer T3U) consume more energy.
• 🔄 Communication stability: Built-in modules work better with antennas located in the laptop lid.
• 🔒 Security: Some corporate networks block connections through external devices.

Technical limitations: slot and protocol compatibility

Not every slot is suitable Wi-Fi module supports SSD. Here are the key points:

Parameter	Wi-Fi module	SSD (NVMe/SATA)	Notes
Slot type	M.2 Key A/E	M.2 Key M/B/B+M	Slots Key A/E not compatible with SSD! Need to search Key M or universal B+M.
Protocol	PCIe ×1 or USB	PCIe ×2/×4 (NVMe) or SATA	NVMe SSD in slot ×1 will work in reduced mode (speed up to 1000 MB/s instead of 3500 MB/s).
Voltage	3.3 V	3.3 V (SATA) or 1.8 V (NVMe)	Some older laptops do not support 1.8 V - NVMe SSD will not be detected.
Antennas	2 pcs. (MHF4)	—	After replacement, the antennas will remain unused (can be disabled in the BIOS).

How to check a slot?

1. Download the utility HWiNFO and see information about M.2-ports in the section Motherboard → M.2.
2. Or disassemble the laptop and inspect the connector: if there is notch on one side only (key A/E) - SSD will not work.

What do M.2 keys look like?

The A/E key has a notch on the left (for Wi-Fi), the M key on the right (for SSD), and the B+M on both sides (universal).

⚠️ Attention: In laptops HP Pavilion, Acer Swift and some ASUS ZenBook slot M.2 maybe blocked at the BIOS level for third-party devices. Before purchasing an SSD, check if your model supports whitelist (list of allowed devices).

Step-by-step instructions: how to physically replace Wi-Fi with an SSD

If you are sure that the slot is compatible, follow the algorithm:

Step 1. Removing the Wi-Fi module

1. Remove the bottom cover of the laptop (usually held in place by screws T5 or PH0).
2. Disconnect the antennas from the module (gently pull the black connectors MHF4).
3. Unscrew the screw securing the module and remove it.

Step 2. Install SSD

1. Insert the SSD into the slot at an angle of ~30° and secure with a screw.
2. If slot Key M, but the SSD is not detected - check the setting in the BIOS PCIe Mode (must be Auto or Gen3).

Step 3. System setup

• 🖥️ If the SSD is not visible in Device Manager — update the chipset drivers (download from the laptop manufacturer’s website).
• 🔄 For NVMe SSD you may need to enable AHCI in BIOS (section Advanced → SATA Mode).

How to connect to the Internet without built-in Wi-Fi?

After replacing the module, you will need an alternative method of connecting to the network. Options:

• 📶 USB Wi-Fi adapter: budget solution (from 500 ₽), but it takes up the port and can slow down Wi-Fi 5 due to USB 2.0 limitations.
• 🔌 Ethernet over USB: adapters USB-C → RJ45 (For example, Baseus 1000M) provide a stable 900 Mbit/s, but require a cable.
• 📱 Mobile Internet: smartphone in mode USB tethering or 4G modem (For example, Huawei E3372).
• 💻 PCIe splitter: a rare solution for laptops with M.2 Key B+M, allows you to connect both SSD and Wi-Fi at the same time (example: ADT-Link R43SG).

Option	Speed	Price	Cons
USB Wi-Fi (Wi-Fi 5)	up to 433 Mbit/s	500–1500 ₽	Occupies the port, heats up, lags under load
USB Wi-Fi (Wi-Fi 6)	up to 1200 Mbit/s	2000–4000 ₽	Requires USB 3.0, high power consumption
USB → Ethernet	up to 1000 Mbit/s	800–2000 ₽	Binding to a power outlet, inconvenient when traveling
PCIe splitter	Wi-Fi 6 + SSD	5000–8000 ₽	Difficult to find, may not work on some laptops

⚠️ Attention: If you are using USB Wi-Fi adapter chip based Realtek RTL88x2BU (For example, TP-Link T4U V3), be prepared for driver problems on Linux. These chips often require manual kernel compilation!

Top 5 SSDs to replace Wi-Fi: which models to choose?

If your slot supports NVMe, pay attention to compact models with low power consumption:

• 🥇 Western Digital SN570 (500 GB–1 TB): one-sided (no components on the back), speed up to 3500 MB/s, suitable for thin laptops.
• 🥈 Crucial P3 Plus (1–4 TB): budget option with DRAM cache, but gets hot under prolonged loads.
• 🥉 Samsung 980 (250 GB–1 TB): reliable, but bilateral - Check the height of the laptop case.
• 4️⃣ Kingston KC3000 (500 GB–2 TB): optimized for PCIe 4.0, but in slot ×1 it will work at speed PCIe 3.0.
• 5️⃣ Transcend 220S (240–960 GB): the only one on the list with 5 year warranty, but slower than competitors.

For slots SATA (rare in modern laptops) suitable:

• 🔹 Crucial BX500 (120–2 TB) is the cheapest option.
• 🔹 Samsung 870 EVO (250 GB–4 TB) - reliability and DRAM cache, but more expensive.

Common problems and their solutions

Even if everything is done correctly, problems may occur:

1. SSD is not detected in BIOS

• 🔧 Check if it is turned on M.2 Slot in BIOS (section Advanced → Onboard Devices).
• 🔧 Update BIOS to the latest version (for example, for Lenovo ThinkPad T480 version required 1.40+ for NVMe support).
• 🔧 If the slot Key A+E, but the SSD is physically inserted - it will not work (an adapter is needed).

2. The laptop does not turn on after replacement

• ⚡ Check if you have shorted the contacts on the board (use a magnifying glass).
• ⚡ Remove the SSD and try to turn on the laptop - if it works, the problem is in the drive.

3. SSD speed is lower than expected

• 📉 In slot PCIe ×1 maximum speed is ~1000 MB/s (even for NVMe).
• 📉 Check the operating mode in CrystalDiskInfo: if specified PCIe 2.0 x1, update your chipset drivers.

How to check SSD speed?

Use the utility CrystalDiskMark (sequential read/write test) or AS SSD Benchmark. The norm for PCIe ×1 is 800–1000 MB/s.

Alternative solutions: when not to sacrifice Wi-Fi

If your laptop does not support replacement or you are not ready to lose the built-in Wi-Fi, consider these options:

• 🔄 Replacing HDD with SSD: if the laptop has it 2.5" SATA-slot (for example, in HP ProBook 450), install the SSD there, and move the HDD to the external box.
• 📁 Cloud storage: Google Drive, Yandex Disk or Mega with automatic backup (suitable for documents, but not for games).
• 🔌 External SSD: drives with interface USB 3.2 Gen 2 (For example, Samsung T7 Shield) give speeds up to 1000 MB/s.
• 🖥️ Network Attached Storage (NAS): if you have a router with a USB port at home (for example, ASUS RT-AX88U), connect the HDD to it and configure access via SMB.

For gamers and professionals working with large files, the optimal solution will be external SSD with Thunderbolt 3/4 (For example, OWC Envoy Pro FX). Such devices provide speeds of up to 2800 MB/s and do not require sacrificing built-in Wi-Fi.

FAQ: Frequently asked questions

Is it possible to get Wi-Fi back after installing an SSD?

Yes, if you have not damaged the antennas or slot. Simply remove the SSD, insert the Wi-Fi module back and secure it with a screw. In 90% of cases, the system will automatically pick up the module, but you may need to reinstall the drivers (especially if you updated the BIOS).

Will the SSD get hot in the Wi-Fi slot?

The temperature depends on the SSD model and laptop ventilation. Compact drives without a heatsink (for example, WD Black SN770) in thin ultrabooks can heat up to 70°C. To avoid throttling, choose models with low TDP (for example, Crucial P5 Plus with controller Phison E18 consumes 20% less energy than Samsung 980 Pro).

How to transfer the system to a new SSD installed instead of Wi-Fi?

Use cloning programs: Macrium Reflect, Clonezilla or AOMEI Backupper. Algorithm:

1. Connect the new SSD via USB adapter (For example, ORICO M.2 Case).
2. Launch the cloner program and select the option Disk Clone.
3. Specify the source drive (usually C:) and target (new SSD).
4. After cloning, remove the old SSD and boot from the new one.

If the laptop does not boot, check the boot order in the BIOS (Boot Order).

Is it possible to use the Wi-Fi slot to install a second SSD without removing Wi-Fi itself?

Technically this is only possible in two cases:

1. Your laptop has additional M.2 slot (For example, Lenovo Legion 5 often equipped with two slots).
2. Are you using PCIe splitter (For example, ADT-Link R43SG), which allows you to connect both SSD and Wi-Fi at the same time. However, these adapters:
• They are expensive (from 5000 ₽).
• May not work on some laptops due to BIOS limitations.
• Reduce SSD speed (as bandwidth is shared between devices).

Which laptops definitely support replacing Wi-Fi with SSD?

Among the popular models with suitable slots:

• Dell Latitude 7490/7590 - slot M.2 2230 Key A+E, but supports NVMe via adapter.
• HP EliteBook 840 G5/G6 - slot M.2 2230 Key E, but you can install an SSD with a key B+M after modification.
• Lenovo ThinkPad T480/T490 - two slots M.2, one of which is often free.
• ASUS ROG Zephyrus G14 - slot M.2 2230 under Wi-Fi, but supports NVMe SSD (you need to disable CNVi in BIOS).
