Frequently Asked Questions

Wi-Fi 6 vs Wi-Fi 7 - what's the difference?

The Wi-Fi Alliance periodically releases new standards that introduce features designed to improve connection performance, reliability, and security. Wi-Fi 7 is the latest standard, formally introduced in 2024. Since its release, MediaTek has launched a full suite of chipsets supporting the new standard, enabling device makers to offer a range of products—from entry-level to flagship access points, routers, mesh networks, repeaters, and more, to meet global market needs.

With different generations of Wi-Fi devices still on the market, you may be concerned that you need to replace all your devices. This is not the case. Wi-Fi is inter-compatible, so a Wi-Fi 7 router will still support Wi-Fi 6, 5, and 4 devices, for example. Conversely, a newer device can also connect to an older access point, although only two devices using the same standard can take full advantage of all its features.

Is it worth choosing Wi-Fi 7 over previous Wi-Fi 6 or 6E standards for your next wireless networking purchase? Here's an overview of the differences:

Speed:

  • Wi-Fi 6/6E: Up to 9.6 Gbps
  • Wi-Fi 7: Up to 36 Gbps

In its top specification, Wi-Fi 7 is capable of extreme performance, delivering speeds up to three times greater than Wi-Fi 6E. This is especially beneficial when an access point or mesh network needs to create a wireless inter-node backhaul without bottlenecks or serve multiple data-demanding clients simultaneously. Flagship devices will offer the highest speeds, but not everyone requires such high performance. Lower-tier models reduce speed through hardware optimizations, such as a reduced number of antennas, which also makes the devices more affordable and accessible, while still providing a full suite of core Wi-Fi 7 features.

Latency:

  • Wi-Fi 6: Improved over Wi-Fi 5, but still variable under load
  • Wi-Fi 7: Significantly lower latency, ideal for AR/VR and gaming

It's not just big bandwidth numbers that's important, the time it takes for your data packets to be received and get processed is also important, especially in busy network environments with lots of devices competing for access. Thanks to improvements such as MLO (see below), Wi-Fi 7 is notably more efficient, which is important for latency-sensitive applications such as gaming, streaming and video conferencing. 

Frequency Bands:

  • Wi-Fi 6: 2.4GHz and 5GHz
  • Wi-Fi 6E 2.4GHz, 5GHz and 6GHz
  • Wi-Fi 7: 2.4GHz, 5GHz and 6GHz, but uses all three bands more efficiently

Wi-Fi 6E introduced a third 6GHz band into the Wi-Fi standard for the first time, unlocking more wireless space to accommodate the increasing number of wireless devices in our lives. On the surface Wi-Fi 7 supports the same three bands as Wi-Fi 6E, although it uses them more efficiently because of one key technology...

Multi-Link Operation (MLO):

  • Wi-Fi 6: Not supported
  • Wi-Fi 7: Supported 

MLO combines multiple bands (2.4, 5, 6GHz) for better speed, and reliability. MediaTek's 'single-chip' MLO implementation is industry-leading, reducing latency up to 80%, and providing up to 300% greater throughput. Learn more.

Smart Link Dispatching

  • Wi-Fi 6: Not supported
  • Wi-Fi 7: Supported

A MediaTek exclusive technology, Smart Link Dispatching enhances standard MLO with multi-link spectrum efficiency upgrades to improve throughput. Learn more.

Addressable Channel Width:

  • Wi-Fi 6: Supports up to 160 MHz
  • Wi-Fi 7: Supports up to 320 MHz

Wider channels = more data throughput, and Wi-Fi 7 doubles the potential wireless channel bandwidth each client can use. This happens automatically without requiring the user to adjust any settings.

Modulation:

  • Wi-Fi 6: Uses 1024-QAM
  • Wi-Fi 7: Uses 4096-QAM 

A higher order modulation provides higher spectral efficiency, which means greater data throughput. This happens automatically without requiring the user to adjust any settings.

MU-MIMO Enhancements:

  • Wi-Fi 6: 8x8 MU-MIMO (up/downlink)
  • Wi-Fi 7: Improved MU-MIMO efficiency

While Wi-Fi 6/6E introduced a significantly more advanced MU-MIMO (multi-user, multi-stream access) compared to the previous generation of Wi-Fi, Wi-Fi 7 further improves this with better scheduling and more simultaneous streams, making it ideal for accommodating many devices at once.

Bandwidth Efficiency:

  • Wi-Fi 6: Efficient in crowded environments
  • Wi-Fi 7: Adds features like MRU and Preamble Puncturing to use spectrum more effectively

To support the increasing network demands of high-throughput and low-latency use cases, as well as multiple simultaneous users in dense environments, Wi-Fi 7 introduces a new feature called MRU, or Multiple Resource Units. This means that a Wi-Fi 7 access point can allocate different block sizes (resource units) to use the available wireless spectrum more efficiently, especially if some frequency ranges are subject to interference. This can improve latency by up to 25% compared to Wi-Fi 6

WiFi vs Internet: What's the Difference & Why It Matters?

Many people in South Africa often mix up Wi-Fi and the Internet — though they’re connected, they’re not the same. Understanding what each does can help you troubleshoot issues faster, pick better hardware, and get the most from your fibre service.

At Teknifi, we strive to give you a top-tier online experience — that means high-speed fibre-based Internet paired with quality routers (WiFi-6 capable, where possible) so your home is covered with strong, consistent wireless connectivity.

What is the Internet?

  • The Internet is the global network through which you access games, streaming services, websites, or anything online.

  • Fibre Internet, in particular, delivers speed, stability, and low latency — ideal for gamers, streamers, and people working from home.

  • Having good Internet means strong performance both ways: fast downloads and uploads.

What is Wi-Fi?

  • Wi-Fi is the wireless signal inside your home that lets devices (phones, consoles, computers, TVs etc.) connect wirelessly to the Internet without cables.

  • It comes from your router, Wireless Access Points (WAP) or Wireless Mesh. Its strength and coverage depend on router placement, how up-to-date the hardware is, the size and layout of your home, and whether there are obstacles (walls, floors) interfering with the signal.

Here’s a critical point: Your device can show Wi-Fi bars (i.e. that it’s connected to the router), even if the fibre line to the Internet is down. That’s why you might see full Wi-Fi signal but still be unable to browse, stream, or work online.

Key Differences: Wi-Fi vs Internet

It’s easy to confuse Wi-Fi with the Internet, but here’s how they differ:

Internet

  • The global connection your ISP provides to access websites, streaming, downloads, and gaming.

  • Your speed depends on the quality and capacity of your fibre line.

  • Reliability issues usually come from line quality, ISP stability, or broader network routing.

  • For gamers, if your Internet is unstable, you’ll experience lag and spikes even if your Wi-Fi is strong.

Wi-Fi

  • The wireless signal inside your home that connects your devices to your router, Wireless Acces Point or Wireless Mesh.

  • Speed and strength depend on your router hardware, placement, distance, and obstacles like walls or other devices.

  • Reliability concerns often come from weak signal zones or interference.

  • Even if your Internet connection is excellent, poor WiFi can cause lag, packet loss, or slow speeds.

Why It Matters for South African Gamers

  • For gaming, every millisecond counts. A solid fibre Internet connection with low latency is essential.

  • Upload and download speeds both matter for streaming, voice chat, updates, etc.

  • While a wired (Ethernet) connection still gives the most stable, lowest latency performance, Wi-Fi can be very goo, but only if the signal is strong and the router is well placed.

FAQs

Does having Wi-Fi mean I have Internet?
No. Wi-Fi is just the wireless network your devices use to talk to your router. If your fibre or ISP connection is down, you’ll have Wi-Fi but no Internet access.

Why is my Wi-Fi “on” but Internet’s not working?
This usually means your router is broadcasting correctly, but the upstream Internet link (from the ISP or fibre line) is interrupted. Restarting the router or checking with your ISP can help.

Which is faster: Wi-Fi or Fibre?
Fibre connection itself is faster and more reliable.

Wi-Fi is how you distribute that connection inside your home, but it introduces variables (signal strength, interference) that can reduce real-world speeds.

Can I game on Wi-Fi?
Yes, especially with a good fibre connection and modern gaming router. But for competitive gaming or when every millisecond counts, wired Ethernet is usually better. 
Router usually provided by any ISP are their entry-Level routers, for Gaming, multiple streaming you would require a fast Gaming Router

Is 100/100mbps fast enough for a family of 5?
Yes, 100Mbps fibre is generally good for a family of 5 in South Africa, handling multiple HD streams, gaming, and browsing, but it starts to get tight if everyone uses the internet heavily simultaneously; for heavy users or many devices (over 6-8), 200 to 300Mbps+ is better to avoid slowdowns, especially in the South Africa where average speeds are higher. It supports core activities well but may struggle with intense simultaneous 4K streaming or large file sharing by many users at once.

When 100Mbps is likely enough:

Typical Use: General browsing, email, social media, and streaming HD video (Netflix, YouTube) on several devices simultaneously.
  • Moderate Gaming & Video Calls: Comfortable for a few people gaming or doing video conferences (Zoom, etc.).

  • FCC Standard: 100Mbps is now considered the baseline for high-speed internet in the SA. 
When you might need more (200 or 300Mbps+):
  • Heavy Usage: If multiple family members are 4K streaming, You Tubing and on multiple Social Media Platforms, competitive online gaming, or live-streaming at the same time.

  • Many Devices: A large number of smart home gadgets and connected devices can eat into available bandwidth.
  • Large Downloads: Frequent sharing or downloading of huge files.
    In South Africa: 100Mbps is a solid mid-range plan, sufficient for most, but higher tiers are available if usage demands it. 
In Summary: 100Mbps is a solid foundation, but for a family of 5 with diverse, heavy internet use, consider upgrading to a 200 - 300Mbps or higher for a smoother, buffer-free experience.

  4. Copy the .nk2 file to the new computer in the folder in which Outlook configurations are saved. Because the default folder is hidden folder, the easiest way to open the folder is to use the command %APPDATA%\Microsoft\Outlook in the Windows Search box (or, browse to C:\Users\username\AppData\Roaming\Microsoft\Outlook).

  5. After the file is copied to the folder, right-click the file, click Rename, and change the name to match the profile name that you noted in step 3.

Step 3: Import the Auto-Complete List

You are now ready to start Outlook and import the file, but you must start Outlook with a special one-time command.

  • Type outlook /importnk2 in the Windows Search box and then press Enter.

The Auto-Complete List should now have the entries from your other computer when you compose a message and begin typing in the To, Cc, or Bcc boxes.

What to do if "iPhone is disabled. connect to iTunes" errors appear

How to fix "iPhone is disabled. Connect to iTunes" - 3 Ways

There are 3 main options for fixing a disabled iPhone — with iTunes & Finder, iPhone Unlocker software, and Find My iPhone feature. Either way, it will factory reset the iPhone and erase all your data and settings. Hopefully you have recent backup somewhere that you can restore the data from.

Option 1: How to unlock iPhone with iTunes & Finder

To connect the disabled iPhone to iTunes or Finder for restore, make sure you have a computer available to use. If not, borrow a friend's laptop.

Step 1: Make sure that the iPhone isn't plugged into your computer

Even if you do this, the computer doesn't recognize your iPhone.

Step 2: Enter Recovery Mode

If you have an iPhone 8 or newer model:

1. Press and hold the Side (also called Power, Sleep/Wake) button and either the Volume Up or Volume Down button until the power off slider appears.

2. Drag the slider to the right wait for the iPhone to power off.

3. Next, hold the Side button while connecting the disabled iPhone to the computer.

4. Keep holding the Side button until iTunes (or Finder) recognizes iPhone in Recovery mode.

If you have an iPhone 7 or iPhone 7 Plus:

1. Press and hold the Side button until you see the power off slider.

2. Swipe the slider to the right and wait for the iPhone to shut down.

3. Hold the Volume Down button while connecting the iPhone to the computer with USB cable.

4. Let go of the Volume Down button when the Recovery mode screen appears.

If you have an iPhone 6s or older model:

1. Press and hold the Side (or Top) button and wait for the "Slide to power off" bar to appear.

2. Turn off the iPhone.

3. Connect the iPhone to the computer while holding the Home button until you see the Recovery mode screen.

Step 3: Locate your iPhone in PC or Mac

Since macOS Catalina, Apple use the Finder app to handle syncing, backup, and restore tasks. In Windows, iTunes still takes care of everything.

On Mac running Catalina or newer macOS version

Open Finder app on your Mac, your iPhone should appear under Locations in the sidebar of the Finder window. Click the device name to select it.

On Mac running Mojave or older macOS version

Open iTunes on your Mac (make sure you have the latest version), and select the iPhone's icon in the upper-left corner of the window.

On PC running Windows

Once your iPhone is detected by the iTunes for Windows, click the device icon in the upper-left corner of the program window.

Step 4: Restore the iPhone to factory settings

Once you've selected your device, you should see the option to Update or Restore your iPhone. Click Restore to proceed.

The computer will start download the latest iOS software from official site and restore the disabled iPhone. This may take a few minutes. Your device might exit recovery mode if the download time takes over 15 minutes,. If that's the case, you'll need to shut off the iPhone and re-enter the recovery mode by repeating the steps outlined above again.

Wait for the iPhone to be erased completely, including all your data and screen passcode.

Step 5: Set up the iPhone and restore from backup

Go through the prompts on the iPhone to set up it. Along the way, you have the option to restore the iPhone with a recent backup.
