Slow remote connection — what causes it
Before assuming the computer or the remote access program is broken, check these few things — the internet connection is usually the real culprit.
What to check
Check the internet speed on both ends
A remote connection is only as fast as the slower of the two links — the office internet might be fast, but if you're connecting from home over weak Wi-Fi, that's where to look first.
Close unnecessary programs and browser tabs
Too many open apps or tabs put extra load on the computer and the network, which makes the remote screen refresh slower than it could.
Lower the display quality in the app's settings
TeamViewer, AnyDesk, and Windows Remote Desktop all let you reduce the display quality — a lower resolution and fewer colors can noticeably speed things up on a weaker connection.
Check if someone else is loading down the network
Large downloads, system updates, or video streaming on the same network can noticeably slow down remote connections for everyone else sharing that link.
Where the slowdown actually comes from
A remote desktop is essentially streaming a live picture of a screen — the more data that needs to move and the slower the connection along the way, the more noticeable the lag. That's why the same program can feel smooth in the office and sluggish over weaker Wi-Fi in a cafe.
When it's a job for IT
- The connection is slow despite good internet on both ends and closing unnecessary programs
- The slowdown appeared suddenly, even though everything was working fine before
- The problem affects only one specific computer while others connect without delay
- Lowering the display quality in the settings makes no difference at all
