anyone know why this phone's wifi and Bluetooth signal break up together? the moment my wifi struggles, and it happens often but resolves itself, the Bluetooth also struggles.

I have been having intermittent issues with Bluetooth audio cutting out on my Captivate while I am on a phone call over Bluetooth. I believe the problem stems from Samsung's inability to do anything right and their implementation of Bluetooth 3.0. A new feature of Bluetooth 3.0 is the ability for a Bluetooth connection to transfer data over Wifi if both Bluetooth devices support 3.0 and have compatible Wifi chips. Samsung implemented this poorly, not a real surprise, and now Wifi is causing the Bluetooth data transfers to be spotty causing streaming data, voice calls or audio streaming, to to be adversely affected.
I was able to finally narrow down the problem. I received a phone call yesterday on my cell phone and I picked up the call on my Bluetooth enabled home phone. The call sounded horrible, noise and the other caller was cutting out, but not enough that I couldn't understand the other person, so I continued the call. The person on the other end did not seem to have any idea that the call sounded so badly, so it seemed to be something limited to my end. During the call, I went over to my Captivate and turned off Wifi. Instantly, the call cleared up and the quality was good to excellent.
I use Wifi all of the time especially at home, so I wasn't going to be turning off Wifi all of the time, so I needed a workaround. Using an App called Setting Profiles, I am able to have Wifi automatically turn off anytime I am on a call and then when the call is completed it turns Wifi back on. What's even better is that the app will note the state of Wifi before a call, so if Wifi is already off before a call, it will not turn Wifi on when the call is ended. The Tasker app will allow you to do the same thing, so if you already have Tasker you won't need Setting Profiles.
This tip will probably only work on the Samsung Galaxy S line because these phones use Bluetooth 3.0, where most Android phones use 2.1 or earlier and do not support Bluetooth file transfers over Wifi. I have only experienced it on the Captivate so I can't say if it will work for any other Galaxy S phone.
Since both wi-fi and BT uses the same 2.4Ghz frequency, interference maybe anticipated although new BT hardwares are pretty good at reduce such interferences.
Did you try change your wi-fi router frequency/channel so that it won't interfere with your BT? Try that so that you may not need to turn off wi-fi on the phone at all.
I have had the issue occur in my car while not near any Wifi router. Also, the router was still on when the call quality improved. It's not like the radio waves from the router and three other Wifi devices in my house disappeared around my phone just because I turned off the Wifi on my phone.

Thanks for the tip
every time i use wireless tether after i have switched it off none of my bluetooth devices will connect to the phone until I reboot.....anyone else experience this?
Have not tried that yet - But I di have a Bluetooth - WiFi issue. If i try to uese Bluetooth on a WiFi call, it usually does not work right.
I had similar problems CM7 on a different device, but not with stock. Am on stock now and not happy
Bluetooth working excellent!
WiFi calling working excellent!
I will try to use wireless tethering....
5 min, please
Yes I have experienced BT connection issues. Even after a reboot. It sometimes will take 2-3 mins for my headset to connect.
No issues here

No issues here either. I was actually just saying to myself this phone has one of the best Bluetooth implementations I've ever seen so far. I've used with BlueAnt S4 car speakerphone and my car's A2DP audio bridge simultaneously as well with other devices by themselves such as a Bose BT1 headset, a Motorola DC800 A2DP audio bridge, and various Broadcom based adapters in computers... no issues at all (which really surprises me). I've used WiFi tethering extensively and leave Bluetooth enabled and never have any issues when I go to connect.
I had a similar problem on CM ROM's on Mt4G, but that was because of poor strength of WiFi in CM kernel - it would disconnect the WiFi.
With G2X, it stays connected, and the Bluetooth is connected when on WiFi calling, but sound only on the device - not through the bluetooth. Calling on Network - Bluetooth works fine.
I am in home office, so use WiFi most of time.
Another issue - but probably not the G2x- Google voice dialing really sucks. Also was the case on MT4G - used Dragon Diction/Genus App - much better. Trying a market app, but not as good as D&G.
Works for me. I turned Bluetooth on first, and then Wi-Fi calling.
i syned my earpiece to BT had to restart the phone now it wont pair or find the device when i hit scan

May not have tried it that way yet - will give it a whirl.
I have a similar issue relating to bluetooth and wifi...here is my issue:
If I have both BT and wifi tether on it works, but as soon as i turn off WiFi tethering none of my BT devices will connect untill I reboot
I am also having trouble with my blue tooth. I use a handsfree device in my car. It syncs the blue tooth but seems to mute the sound. It doesnt work.
Hello everybody.
I am bit fed up with that problem.
Everytime when I am listening (or watching) over stereo bluetooth and connected to wifi have some problems.
Instant interupptions after few minutes or even seconds sometimes.
So my question is if anyone of you have some bluetooth and can listening for example internet radio when connected to any wifi without trouble.
If it is over 4G there is no problem at all.
I am pretty sure that from hardware site it is that both wifi and bt chips are in one.
But can anybody confirm on CyanogenMod or any other that there is no problem with that?

Last I checked, our current CM builds have problems when both bluetooth and wifi are enabled at the same time. It's being worked on.

Thanks a lot Jax184, as this is very important to me.
I will only go for other ROM if that will be sorted.

Every device I've tried with my note 10 has had awful bluetooth crackle unless I really turn down the volume. For some devices (car etc) this is fine, but for something like headphones they become unusable, either being too quiet or sounding awful.
Anyone run into this problem, or have a fix for it? I'm going to try factory resetting the phone and if that doesn't work I will get rid of it and buy something else.
I use my Mi Note 10 with Global rom with my Mondeo mk4 (FL). Full volume, zero crackle/issues.
Check Developer Options, as far as I know you can specify like codecs and whatnot. You might have to set that on your car.
Figured it out. The crackle for me happens when I'm connected to a weak 2.4GHz WiFi access point. Connecting to a 5GHz WiFi or a strong 2.4GHz signal solves the problem completely
It's co channel interference between WiFi and Bluetooth. Hopefully Xiaomi can make some improvements in updates (changing modulation, etc)
