Do LED Drivers affect WiFi?

Since i added a new light to my tent my WiFi has been sucking bad, could this be the reason, or is it just coincidence?

Switching power supplies ,like LED drivers are operating in the range from tens of kHz to a few MHz .

Since the operational frequencies of
WI-Fi are 2.4 GHz and 5 GHz,
it’s quite unlikely that a certified and
quality LED psu will interfere with the
Wi-Fi data transmission .
But ...
In the case of a faulty and /or low quality unshielded and filter-less psu,
then there can be harmonics that could possibly may be causing interference .
Still highly unlikely ,but can’t be ruled out completely.

Try switching OFF the light fixture and unplug it from the mains .If your Wi-Fi operates as usual afterwards ,then you will know for sure that something is really going wrong .

Be cautious at such case.
It may be that not only your Wi-Fi
gets messed up ...
Maybe trouble is caused at nearby ,
other wireless connections also.

In some cases such
EMI/RFI issues had a radius of half a kilometer
( 400 Watt HPS digital ballast messed up the reception of the WHOLE AM radio band ,at a radius of about half a kilometer around the grow tent ! Nobody was able to listen to any AM radio broadcast ,at one third of a mile radius ! ) ....

Thank you so much for taking the time to answer in such detail. I will do your troubleshooting to see what i get. Take care
