Bluetooth WiFi antenna questions
I had issues with my fan/overheating and after cleaning/testing it was determined that it was the fan that needed replacement. I bought a new official product replacement and took it down to a well known and awesome indie gaming store here in NYC to install it for me for 40$. I did not have total confidence in my abilities to fix this myself, if this wasn't my main/only PS4 I wouldn't have been that worried. After getting it back, right out of the gate my controller was having delay issues and would only work if pointing right at the console, tho finding, pairing and staying connected was never an issue. After trying other controllers and hooking the console up in another room that is free of other wifi/Bluetooth devices, I would get the same result. Now, I cannot blame the shop for sure which is why they are being nameless and why I didn't contact them about the problem. So, here is my question: The Bluetooth receiver also doubles as a wifi antenna. I have ZERO issues with WIFI on my console when I use it. In fact, I am able to connect to hotspots that none of my other devices, PC included can even see let alone connect to. If issues with the Bluetooth controllers are so bad, wouldn't the WIFI also have some issues too since I am almost positive something happened to the wire and they both use it.
When my internet goes down I switch from Lan to local hotspots with in my area to connect in order to play my digital copies or watch Netflix. No issues on that end.
The antenna is an incredible easy fix, and I’m thinking of modding an external hookup, I just want to know more on how antenna works and if my understanding is correct.
Any ideas?
Ist dies eine gute Frage?

Hi,
Don't know the answer but Bluetooth in most devices has a limited range of 30' barring any obstructions or any other interference etc.
In other terms it means less power is being used to transmit than what WiFi requires for longer distances.
Bluetooth can also operate at longer distances but this is dependent on which "Class" of Bluetooth it is 1, 2, 3, 4 or 5. Most common devices are Class 2 i.e. transmit power 2.5mW range 30'
It most devices it uses the same antenna as the WiFi (both operate at 2.4GHZ).
So it may be more of a power issue for the Bluetooth than an aerial issue.
Pointing the controller directly at the console just maximises the received signal at both ends ensuring a stable connection
You mightn't be able to blame the shop but you could contact them and politely ask why if it was working OK before it went in why isn't it now.

Sorry it took me a bit to get back.
When you say it may be a power issue, what exactly do you mean?
My PS4 is not getting the maximum voltage it supposed to from a wall outlet? (wall socket may be faulty)
It would seem that if one would fail (faulty power from the antenna) then I would also have wifi issues to some degree.
It's been almost 7 months since the repair so I can't really contact the retro game store about the issue now because well, there is no proof unlike say, I took it in the day after. TBH, it took them over a month to replace a simple fan because they had to order the new part and then the part became "lost in the mail" so they had to order another one. I know $@$* happens and this was not their fault, so at the time I was just so happy to get it back that the thought of having to do this all over again wasn't a good one.
I am burning thru gamepads tho because of the $@$*!& USB port. I paid 10 bucks for Gamestop Controller insurance so I get a unlimited replacements for 10$ an exchange.
