When I connect my Bluetooth sound speaker my WiFi slows down. Sometimes it doesn't open anything anymore. I read it's a conflict due to radio frequency but I couldn't find any settings to change it on Windows.

The problem you are experiencing is due to interference caused by RF overlapping channels.
802.11 RF Channel Specification:
The IEEE 802.11 standard establishes several requirements for the RF transmission characteristics of an 802.11 radio. Included in these are the channelization scheme as well as the spectrum radiation of the signal (that is, how the RF energy spreads across the channel frequencies). The 2.4-GHz band is broken down into 11 channels for the FCC or North American domain and 13 channels for the European or ETSI domain. These channels have a center frequency separation of only 5 MHz and an overall channel bandwidth (or frequency occupation) of 22 MHz. This is true for 802.11b products running 1, 2, 5.5, or 11 Mbps as well as the newer 802.11g products running up to 54 Mbps. The differences lie in the modulation scheme (that is, the methods used to place data on the RF signal), but the channels are identical across all of these products.
There is also a good explanation in here that why it's better for you to use non-overlapping channels. so based on that, you need to use these non-overlapping channels (1-6-11). Bluetooth technology uses 79 channels.
so first connect all 3 devices at the same time to your Laptop then do the followings:
- For the internal Wifi receiver of your laptop:
you can't configure the receiver but you should configure the signals's source, your wireless router. this must work if the IP address of your wireless network adapter is something like 192.168.1.x. in order to do that open a web browser and type in 192.168.1.1. it will take you to your wireless router's settings. in the Wireless tab/section change your Wifi channel to 1 and see if the problem with all 3 devices is solved, if not change the channel to 6 and then try, if not change the channel to 11 and try again. if it's solved you don't need to do the below steps but if the problem still exists you need to proceed.
- For your Razer BT mouse
download and install the device's driver/software. once installed, go to its settings. if it allows you to manually set the working channel, set it to 6, but if not then leave it to "Auto channel hopping".
- For your BT headset
install the device's driver/software and do the same thing you did for your Razer BT mouse, if that option is not available, leave it.
and try not to put their receivers near each other. if your problem still exists even after doing all of them then the interference at your place is so high. other devices like cordless phones can also cause interference. i suggest you to use 5Ghz band for your Wifi internet and as your Laptop does not support that, you'll have to also buy a 5Ghz wireless network adapter in addition to 5Ghz wireless router.
Update - I don't think this below is a solution, I think it might have been coincidence that Bluetooth came back after I did this. Leaving it here as something that might sometimes work and an example of something I've tried.
As stated in the update to the question, bluetooth comes and goes. This seemed to help one time when it had gone for hours and nothing else seemed to work, but the problem repeats.
Bluetooth's back and my keyboard works again. I don't understand why it went away, or what the problem was, or how exactly it got fixed, so I'm keeping this issue open, but here are the steps that seemed to have an affect:
I followed the linked MS answer above:
- Opened Services.msc` after searching for it from the Start screen
- Double-clicked the Bluetooth Support service, switched to
Log ontab. - Changed
This accounttoNT AUTHORITY\LocalService - Started the service, rebooted. It claimed to be running, but nothing happened
I later un-did the above...
- From
This account, clicked Browse, then Advanced, then Find now, and choseLocal service - In the password field, I entered my standard user password
- I restarted the service and rebooted the computer
- From
Then suddenly Bluetooth was back. The tray icon is back, I'm typing this on my bluetooth keyboard, the metro-style
Bluetooth settingstakes me to actual bluetooth settings...
I don't know if it was the above that caused it to work, but this is what I did immediately before it worked, and it didn't work immediately before this, so maybe it'll help someone in a similar position.

If your WiFi is using the 2.4 MHz band, i.e. variants 802.11b, 802.11g or 802.11n, it is possible that Bluetooth, which uses frequencies of about 2400 to 2484 MHz and WiFi in the 2400 - 2500 MHz region, are interfering with each other. You can check this by changing the channels your router users: consult the manual for the specific router, e.g. Netgear, XFinity etc. There is information on the web for changing the channel, e.g. How-To Geek. Since this is an easy, free, adjustment, it won't hurt to try it.
Another possibility is that Power Options, Advanced settings for the wireless adapters is reducing throughput. Be sure it is set to Maximum Performance, though this might slightly reduce operating time on battery.
However, it is also possible, as @MichaelBay states, that your PC can't handle the throughput from two wireless devices. You could try an external WiFi or Bluetooth USB device to take some load off your PC, or to use the 5 GHz WiFi band, if your router can do so, but if the CPU itself is the limiting factor, these will not help.
