It seems like the bandwidth test for WP7 tells us that the Bluetooth of the Samsung Focus during a call interferes with the WiFi signal which slows down the download speed over WiFi dramatically.

Can't be Windows doing QOS to keep the call smooth?
Cannot be the QoS, because after turning off Bluetooth during a 3G calling, the WiFi speed is back to normal. There is no problem using iPhone with call and WiFi Internet simultaneously
Both bluetooth and wifi use the same 2.4GHz radio. Try change your wifi router's wifi band to see if it makes any difference.
My download speeds at home on the 5 ghz band setting are around 225-235 mbps, which is the same as my laptop. On the 2.4 ghz band setting my speeds are 85-95 mbps. With my phone set to Auto it always selects 2.4. Can this be fixed? Should I set the phone to always run at 5 ghz? Or should I just forget about it and leave it on auto?
My modem have 2 different wifi
1- Yavuz
2- Yavuz_5G
I'm connect 5Ghz wifi channel always on my device
You must connect 5Ghz channel

The question was for general purposes, like getting the best speeds when I'm out and about, not just for when I'm at home. Sorry I wasn't clear on that.
Hello
So after doing some tests I could verify that...
If you are connected to a Bluetooth device, the wi-fi speed is very much slower.?
Can you do a Speedtest before and after Bluetooth connection with some device...
( I used mi band 3 and a headset to do the tests )
Can you see the difference?? ?
Is there a solution to this??
I can confirm this running Android Pie December's patch. I am using Mi Band 2 and in PUBG Mobile delay is raised from 50ms to 250ms. Turning off Bluetooth solves that instantly.
If you disable GPS (location) speed is a bit better.
only solution is to get 5ghz router(or disable BT while you surfing on the wifi), BT and 2.4 ghz wi-fi are working at about the same frequency

I use WiFi 2,4 ghz AND bluetooth (miband3) all the time on. I use Macrodroid (or automate or tasker) for disabling location (GPS) when I'm connected to my home WiFi so I get full speed WiFi and I can receive notifications from my band.

Is this the case to all devices with similar hardware or is a issue with the Rom programming that makes this use of the same band?
I say it because there's maybe a way to fix this via custom roms, im tired of not being able to watch streams and use my wireless earbuds at the same time....
I have the same similar problem...
When I use my mi band 3 ( Bluetooth watch )
The internet speed is very slow
So, i tried testing the speeds and i found that it's random the type of problem that i got.
In my case im using Apple's Airpods gen 1
- most of the time i have slow or non working wifi connection (tested with youtube and twitch apps) and videos will only load at 144p (at this point is better to not use bluetooth or not watch the video)
- other times videos will not even load
- sometimes the Bluetooth earbuds will start to connect and disconnected continuously and the only way to fix this is turning off Bluetooth and reconnecting again to Bluetooth
- sometimes all problems are fixed in that way but also internet connection becomes a bit sluggish and phone heats up
- sometimes when no audio is playing for a certain time earbuds reconnect but this is maybe a battery saving method in the earbuds themselves
- its literally impossible to watch videos with Bluetooth connected and via wifi if you have a thin wall between you and the router, i live in a small house and being in any room except the one with the router will render video playback impossible.
I think this is more than a wifi - Bluetooth band issue and more of a software issue the more i test this issues
Is there a way or can someone contact Xiaomi to fix this issue? I really feel that this have gone worse since PIE update...
I beginning to think that the problem is the phone hardware, for what I have seen mi A1 uses the same antenna to Bluetooth/ WiFi/ Data
That's why we have this problem of speed...
In other phones, this functions are separated by others antenna...
That's what I think...
To be clear off the bad, its not the router. Every other device in the house that connects to the 5ghz band works flawlessly. This is a brand new international phone being use with AT&T in the US, calls and texts function fine. Phone is fully updated and so is the router.
Wifi however is only picks up 2.4ghz bands. Not 5ghz.
Wifi analyzers pick up 2.4ghz but when switching to 5ghz I get a messages stating my phone does not support 5ghz. Anyone else with this issue?
@aq3e No. It doesn't have 5GHz.
2.4GHz has better penetration through walls anyway.
5GHz is really only good if you're in the same room.

I also dont have 5ghz and dont have the advacned wifi option to change bands... Why this model suck this much? Probably a OS stupid limitation...

5ghz is only good if you're in the same room
The A20 does support dual band, but it's disabled. I tried to enable it by replacing the mx140_wlan.hcf file located at /vendor/etc/wifi/ with the one from the A30 and it worked, but there's a problem.
For some reason the signal range is terrible, to detect a 5 GHz network the phone needs to be next to the router, if it gets some centimeters away the signal drops at the point where the network is not detected anymore.

5ghz wifi is certainly not only good in the same room, check online heatmaps of 2.4 vs 5ghz to compare, it's not a huge difference. Given how much less interference you will get on the 5ghz it often works a lot better than 2.4ghz even at longer ranges. Fix peoples internet for a living and I've seen thousands of peoples speeds double or even triple from changing to 5ghz even when router is on the first floor and they use it on the second.

Read the article here.
It shows that 5ghz suffers from greater attenuation rates than 2.4
2.4 GHz vs. 5 GHz WiFi
Learn about when to use 2.4 GHz vs. 5 GHz WiFi with CenturyLink. The difference between these frequencies can affect your speed.

(I know this doesn't help much with the OP's question but to dispel hearsay I felt it needed to be said.)
I know you don't know me, but I said I resolve peoples internet problems for a living both on supplier and consumer side and have tested this with thousands of customers but you trust a random article with very little info more and don't even bother to look at heat maps? This article has been made by someone who read a blurb about wifi, but they did get one thing right...
"A lot of electronic devices and appliances use the 2.4 GHz frequency, including microwaves, baby monitors, and garage door openers. If you have many of these in your home, or if you live in apartments or condos surrounded by other people, that 2.4 GHz band is likely to be congested, which can damage speed and signal quality."
That list is very short, it also includes lots of computer peripherals, security cameras, smart home devices, walkie talkies, radios, remote controls, wireless handsets (landlines, not mobiles) basically every wireless device you can think of uses 2.4ghz and even your microwave! all these devices on a long range signal means your neighbours devices also overlap to combine together to make the 2.4ghz band for most consumers a disaster for anything requiring more than slow speeds. This goes without even mentioning that the 2.4 ghz band only has 13 channels (3 none overlapping) to spread every wifi device out on to stop interference, in most residential are this is simply not enough. In many cases this is so bad that even next to the router people can lose 80 - 90% of their speeds or have so much interference that even loading webpages takes a long time due to the amount of data being lost.
Like I said before, even if the 5ghz DOES have shorter range, it is not so short that you have to be in the same room, what would be the point? That is a something people assume because it's a "shorter range signal" but it's not that short! the 5ghz is usually faster due to it's naturally higher data rates and more consistent due to the lack of interference from intermittent signals. Most things that interfere with 5ghz are constant and therefore it's much easier to test and know what speed you can get in other rooms away from the router, unlike the 2.4 which has the same issues with passing through anything only with a load of other issues on top too!. The 5ghz also has the advantage of having over 100 wifi channels to spread networks out on to avoid them interfering with each other, a vast upgrade to the 2.4ghz.
Here is an example of a heatmap comparing 2.4 and 5ghz but just looking at any article that goes beyond a very brief description will show you why the 2.4ghz is often so much worse than the 5ghz.
What's the Difference Between 2.4 and 5 GHz WiFi?
What do these numbers actually mean? Does it realy matter? Is one better than the other? How many questions are we going to ask in this description?
socialwifi.com
2ldr - It depends on your house and nearby networks, test both bands with different devices in different rooms and compare speeds, outside of doing more thorough testing with other apps and equipment this is the easiest and quickest way to see which will work better.
You have 2 choises use BT modem BT modem Plan A: one Device in 5GHz network one device sharing Internet from BT modem feature. +Advance use Open Garden mesh client for better Internet throught BT modem. Construction of my plan:One or two devices in 5GHz WiFi network and 3 devices creating PAN network trought Bluetooth.if Your Bluetooth version is 5.0 you can use Mesh network profile. than using Mesh network structure. Mesh Bluetooth network structure helping one device to other. but you need to know you will use 2.4GHz trought BT modem and Mesh networks.

I fixed this issue on crDroidAndroid-13.0-20221126-a20-v9.0 by copying both mx140_wlan.hcf and mx140.bin taken from this a30 git. Works great on my a20.

Interesting. What's your A20 model? I believe I also tried to do that, but I'm going to retry it.
Done it on a SM-A205W.

No luck. I still have the signal issue
Do it again in the following order maybe ?
1. Download both mx140_wlan.hcf and mx140.bin from the git I gave you above.
2. Turn your wifi off.
3. Reach /vendor/etc/wifi folder using your favorite file browser ( Mine is Mixplorer ).
4. Overwrite both files.
5. Reboot your device.
6. Turn Wifi back on.
7. Do a Wifi speed test ( Wi-Fi Sweetspots app for me ).

I use a Magisk Module instead of directly overwriting the files, but this should make no difference. I believe it may be a hardware difference between our devices. On the schematics the 5GHz antenna seems to be marked as optional, maybe that has something to do.
I tried to put my device next to the router, and when I did it the network got detected (with bad signal tough), I could connect and the download speed oscillated between ~50-200 mbps (my network has 300 mbps). Once I moved further from it, the WiFi disconnected as the signal was lost.
Help me find custom Android 10 rom without problems of the wifi speed , while simultaneously connecting with BT devices.
Had the same problem mate!
I changed my wifi frequency to 5 ghz and I am now not facing any problems. Maybe you can try that.
The problem is if your wifi and Bluetooth are on the same frequency channel.
