That’s weird - there shouldn’t be any connection between the two things.
So you have a set top aerial - check the wire is OK, and it’s plugged into the TV.
Is it mains powered? If so, check it is still plugged in at the mains and switched on.
Do you get a TV picture now?
But you are saying if you have the WiFi on (by which perhaps you mean the router on, or perhaps literally the WiFi) that the TV picture goes away?
I might suspect that the engineer unplugged the power to the booster that runs your aerial, and never plugged it back in, in which case the above will fix things.
But perhaps I am doing the engineer an injustice, and it is something else.
Could it be you have a Stick, on one of the HDMI inputs to your set, and you need to switch back to broadcast TV?
Your description of the problem could be so many things - does the above narrow it down at all?
If not can you give us a bit more detail?
If we could see your setup it would almost certainly be easier; that’s not possible, but do you have a techie neighbour, friend or relative who can look at things, see what they can see?
If so, we can answer any residual questions they have, hopefully.
And if it turns out the engineer broke something, we can be sure you need to get him back to fix it 
Still weird 
So at the moment, you can be watching TV, you plug the router in (to a free mains socket? Without having to unplug something else to plug the router in?) and the picture on the TV goes away, the sound goes away, and all you are left with is a completely blank screen?
What’s on the other end of the HDMI cable?
Did you try @schnapps advice to move the router as far away from the TV aerial as possible?
And also make sure the cables aren’t running alongside one another, as this can disrupt things.
But please post the make and model of the TV.
Make should be on the front, model will be on a label on the back of the set. Describe everything on the label if you are not sure which bit is the model; maybe photograph it with a mobile phone camera and post it here, if you can do that.
Then I can look it up, and see what it does and doesn’t do, see what the remote looks like, tell you what to press.
