Can work VPN slow down my wifi connection?

[rh1]

Question is out pf curiosity. I work from home 3 days a week. I connect via the works VPN if I need to access our network. I noticed that it was very slow. I tested via google speedtest on my work laptop and with my phone, from the exact same location:

This is the results, phone:

Yes it definitely could.

If your company does not have options for using a split tunnel, all your internet traffic would be going through the VPN.
This means that when you need to access anything, that internet traffic needs to be routed via the VPN host which I assume is an office in CPT?

Your work VPN is NOT going to slow down your WiFi.. Your work VPN IS going to slow down the device which connects to your works VPN, to the tune of whatever bandwidth limits work has set on the VPN..

This is why you see the speed test difference between your phone and laptop.. if the work VPN doesn't implement split tunnel, all your traffic from the laptop, whether work related or not, will go through the VPN and be limited to whatever bandwidth limits are set there..

To add, they might not even intentionally be slowing it down.
Everyone is aggregating their internet to your works internet connection.
So if your office has a 200Mbps link, and 30 people are connected and all using the link, it gets slow pretty quickly.

Yeah it slows down mine, our office has a 50mb line, i have a 500mb line. I only get 50 max through the VPN

How do you know if the company VPN supports split tunnelling?

How do you know if the company VPN supports split tunnelling?

Traceroute something you know is at your office.

Then traceroute something like 1.1.1.1 or 8.8.8.8.

If the results are different then they are split tunneling. If they are not then they aren’t.

Speaking from experience.

Most companies will install Fortigate on their laptop or computer which then allows said employee to connect to the office LAN via VPN. This should NOT affect the connectivity to other devices on the LAN, which is what I assume the OP means is happening..

However if they're expecting him to VPN using his router, different story.
My router takes a significant knock in performance if a file transfer is happening over VPN (me connecting from outside in)

OP is confusing terms and provides evidence that exactly that isn’t happening as his mobile phone is just fine.
