Your video call freezes mid-sentence. Your colleague’s face blurs into a pixelated mess. You’re left saying “sorry, you broke up there” for the third time this morning.
Sound familiar?
If your home office setup worked fine a couple of years ago but now feels like it’s running through treacle, you’re not imagining things. The demands on home networks and computers have changed dramatically, and kit that was perfectly adequate in 2023 is now struggling to keep up.
The good news? Most of these problems have straightforward fixes. And you probably won’t need to buy a new computer.
Let’s work through what’s actually causing your setup to feel sluggish, and what you can do about it.
The Real Reason Your Setup Feels Slow
Here’s what most people get wrong: they assume slow means broken.
But the frustrating truth about home office tech in 2026 is that nothing needs to be broken for everything to feel sluggish. It’s the micro-delays that drive you mad. The three-second pause before a webpage loads. The grainy video stream. The slight lag between speaking and your colleague hearing you.
These aren’t dramatic failures. They’re death by a thousand cuts.
So why is this happening now?
Three things have changed. First, video calls have become the default way of working. Where you might have had one or two calls a week in 2020, you’re probably on camera several times a day now. Each call demands consistent bandwidth and low latency. Your connection needs to be not just fast, but stable.
Second, software has become hungrier. The tools you use daily (Microsoft Teams, Zoom, Google Meet) have added features, improved video quality, and integrated AI assistants. All of that needs more processing power and more bandwidth.
Third, your home has more devices fighting for attention. Smart speakers, security cameras, thermostats, tablets, phones. They’re all connected to the same network as your work laptop, and they’re all quietly consuming bandwidth in the background.
Research from late 2025 found that three-quarters of employees feel their current remote work tools need improvement. You’re definitely not alone in this frustration.
Is Your Internet Speed the Problem?
Here’s something that surprises most people: you can have a fast internet connection and still experience choppy video calls.
That’s because speed (measured in megabits per second) is only part of the picture. What actually matters for video calls is latency and consistency.
Latency is the delay between you doing something and the internet responding. It’s measured in milliseconds. For smooth video calls, you want latency under 50ms. Anything higher and you’ll notice that awkward delay where you and your colleague keep talking over each other.
Jitter is how much your latency varies. If your connection usually has 30ms latency but every tenth packet takes 500ms, your video software has to build in a buffer to cope with those slow packets. That buffer shows up as lag.
Packet loss is when data simply doesn’t arrive at all. This causes the audio to cut out or the video to freeze.
You can have a 200Mbps connection with terrible latency and jitter, and it’ll feel worse than a 50Mbps connection that’s rock solid.
How to Check Your Real Performance
Don’t just run a speed test. Run a quality test.
- Go to speedtest.net and run a test, but pay attention to the ping number (that’s your latency), not just the download speed.
- Run the test several times throughout the day, especially during your usual working hours.
- If your ping is consistently over 50ms, or if it varies wildly between tests, your connection quality is the issue. Not the raw speed.
If you’re on Wi-Fi, run the same test with your laptop plugged directly into your router using an Ethernet cable. If the results improve dramatically, you’ve identified the problem: your Wi-Fi, not your internet connection.
Why Smart Devices Could Be Slowing Your Work
Take a moment to think about everything connected to your home network right now.
There’s your work laptop, obviously. Probably your phone. Maybe a tablet. But what else? Your smart TV. The streaming stick. Your partner’s laptop. The kids’ gaming console. The smart speaker in the kitchen. The video doorbell. The security cameras. The smart thermostat. That robot vacuum cleaner.
Every one of those devices is connected to your router. And many of them are constantly sending and receiving data, even when you’re not actively using them.
This creates two problems.
First, there’s simple bandwidth competition. When your smart doorbell uploads video to the cloud at the same time as your teenager starts a game download, your video call gets squeezed.
Second (and this is the sneaky one), many smart devices use the 2.4GHz Wi-Fi band. This is the same frequency used by older laptops and devices that need longer range. The 2.4GHz band only has three channels that don’t overlap with each other: channels 1, 6, and 11. If your neighbours are also using these channels (and they probably are), you end up with congestion that causes dropouts and slowdowns.
Quick Fix: See What’s Connected
Log into your router’s admin page (usually by typing 192.168.0.1 or 192.168.1.1 into your browser) and look for a list of connected devices. Most people are surprised by how many things are on their network.
If you spot devices you don’t recognise or no longer use, remove them. Old phones, tablets you’ve replaced, smart devices you’ve unplugged. They might still be trying to connect and causing interference.
Your Computer Might Be Working Harder Than You Realise
Sometimes the problem isn’t your network at all. It’s your computer quietly struggling under the weight of everything you’re asking it to do.
Modern browsers are particularly demanding. If you’re the type to keep 30 tabs open (no judgment, we all do it), each of those tabs is using memory and processing power. Add in browser extensions like password managers, ad blockers, AI writing assistants and grammar checkers, and your browser alone might be consuming most of your computer’s resources.
Then there’s the background software. Microsoft Teams, even when idle, still uses resources. Slack does too. Cloud backup services, antivirus scans, and system updates. They’re all quietly competing for attention.
How to Check What’s Eating Your Resources
On Windows:
Press Ctrl + Shift + Esc to open Task Manager. Click “More details” if you see the simple view. Look at the CPU and Memory columns. If anything is consistently using more than 20-30% of your CPU, that’s worth investigating.
On Mac:
Open Activity Monitor (search for it in Spotlight). Check the CPU and Memory tabs. Sort by usage to see what’s demanding the most.
Common culprits include:
- Browser extensions you installed and forgot about
- Cloud sync services (OneDrive, Dropbox, Google Drive) actively sync large files
- Antivirus software running full scans
- Software updaters checking for new versions
- Old programs you haven’t used in months, but that launch at startup
If your computer is more than 4 or 5 years old and you’re consistently seeing high CPU or memory usage during normal work, it might genuinely need more RAM or a faster storage drive. Sometimes the fix is adding more RAM or fitting a faster SSD, and that’s far cheaper than buying a new machine.
If you notice processes you don’t recognise consuming resources, that could be a sign of malware. Unwanted software running in the background can seriously slow things down. Our virus and malware removal service can clear that up quickly.
5 Quick Fixes You Can Do Today
Right, enough diagnosis. Here’s what you can actually do to speed things up, starting with the easiest fixes.
1. Create a Separate Wi-Fi Network for Work
Most modern routers let you set up a “guest network.” Use this to create a dedicated network for your work devices only. This keeps your laptop separate from the kids’ tablets, smart TVs, and everything else fighting for bandwidth.
It takes about five minutes to set up through your router’s admin page, and it can make a noticeable difference to your connection stability during calls.
2. Prune Your Browser Extensions
Go to your browser’s extension settings and disable anything you don’t use daily. Be ruthless. AI writing assistants, price comparison tools, screenshot extensions. If you’re not using them every day, turn them off.
Each extension runs code on every page you visit. Fewer extensions means faster browsing and less memory usage.
3. Restart Your Router
Yes, it sounds obvious. But “turn it off and on again” genuinely works for networking equipment.
Routers build up cached data and can develop quirks over time. Restarting clears this out and forces fresh connections. If you can’t remember the last time you restarted your router, do it tonight.
For best results, unplug it for 30 seconds rather than just pressing the restart button.
4. Plug In With Ethernet
If you do video calls regularly, connecting your laptop directly to your router with an Ethernet cable is the single most effective thing you can do.
Wi-Fi is convenient, but it’s inherently variable. Walls, distance, interference from other devices, even the microwave running. All of these affect your signal. A wired connection eliminates all of that.
You don’t need an expensive cable. A basic Cat5e or Cat6 cable from any electronics shop will do the job. If your laptop doesn’t have an Ethernet port (many newer ones don’t), a USB-to-Ethernet adapter costs about £15.
5. Clear Your Credential Cache
This one’s a bit more technical, but it’s worth trying if you experience slow logins or laggy access to work files.
Modern security systems use tokens to verify your identity. Sometimes these tokens expire but don’t properly refresh, causing your computer to repeatedly try to authenticate in the background. This creates delays and uses bandwidth you don’t notice.
The fix is simple: sign out of your main work accounts completely (Microsoft 365, Google Workspace, whatever you use), then sign back in fresh. This forces new tokens and often clears up mysterious slowdowns.

When Should You Call in a Professional?
Most home office niggles can be sorted with the fixes above. But some problems need proper diagnosis.
Call in help if you’re experiencing:
Persistent connection problems despite good hardware. If you’ve tried a wired connection, restarted your router, and your speeds still drop during calls, there might be a configuration issue or a problem with your router itself.
Network dead zones that won’t go away. If certain rooms in your home simply won’t hold a signal, you likely need a mesh network system properly installed and configured. Cheap extenders often make things worse. A proper home Wi-Fi installation can give you reliable coverage throughout your home.
Blue screens or unexpected crashes. These usually indicate hardware problems like a failing hard drive, faulty RAM, or overheating components. Continuing to use a computer with these symptoms risks losing your data.
Security concerns. If you’re handling sensitive work data from home and you’re not confident your network is secure, it’s worth getting a professional check. Home routers often ship with weak default settings.
Anything that’s costing you productive time. If you’ve spent hours troubleshooting and you’re still frustrated, that time has a value. Sometimes the smartest fix is letting someone else sort it while you get on with your actual work.

Frequently Asked Questions
How do I know if the problem is my Wi-Fi or my computer?
The quickest test is to plug your laptop directly into your router with an Ethernet cable and see if the problems go away. If everything runs smoothly on a wired connection, your Wi-Fi is the culprit. If problems persist even when wired, look at your computer or your actual internet connection.
What internet speed do I need for video calls?
For a single HD video call, you need about 3-4 Mbps both upload and download. For 4K quality, you need around 15 Mbps. But raw speed matters less than consistency. A stable 50 Mbps connection will feel better than a variable 200 Mbps one. Check your latency (ping) as well as your speed.
Should I upgrade my router or get a mesh system?
If you live in a flat or small house and your router is centrally located, a newer router might be all you need. If you have dead zones in a larger home or across multiple floors, a mesh system will serve you better. Mesh systems use multiple units that work together to blanket your home in coverage.
How often should I restart my router?
Once a month is a good habit. Some people set up automatic restarts overnight using a simple timer plug. If you’re experiencing problems, restart it immediately. It’s always the first thing to try.
Can smart home devices really slow down my work?
Absolutely. Security cameras uploading video, smart speakers listening for commands, robot vacuums checking for updates. They all use bandwidth and can cause congestion on your network, especially if they’re using the same Wi-Fi channel as your work devices. Creating a separate network for work equipment helps prevent this.
When is it worth calling an IT professional?
If you’ve tried the basic fixes and you’re still having problems, or if the issue is affecting your ability to work, it’s worth getting help. Also call a professional for any hardware symptoms like blue screens, crashes or strange noises. Network installations and security concerns are best left to the pros too. The time you spend troubleshooting has a cost.
