My wifi on my tabpro 8.4 is fine until I connect my Bluetooth game controller to it.
It only affects the 2.4ghz part of the card though. i ran some tests and with the bluetooth controller turned off, my 2.4ghz wifi signal was perfect. As soon as i connected the controller, it seems to interfere and all the 2.4ghz wifi signals in my area disappear and reappear every 10 seconds.....as soon as i turn the pad off they all stay there indefinitely.
the pad does not affect 5ghz signal though.
i wonder if there is a fix for this or if it is just a hardware issue?
I know it is just this tab as when i run the same tests on my galaxy s5 there is not interference from the BT controller
Can anyone help me?
I just got a keyboard and mouse, bluetooth. They work awesome but they kill the WiFi on 2.4ghz. I don't have a 5ghz access point at home and none of the places I'd use it have 5ghz right now so it sucks. I'm guessing that no one responded because I don't think k it matters if you're on an ios, Android, or Windows system they both run on 2.4 and conflict and cause issues. Bummer.
Bluetooth runs on the 2.4Ghz frequency and does channel hopping (it's supposed to detect the in use frequencies though) if the game controller is old (pre BT3) it might disable some functions that allow BT to Coexist with wifi on the 2Ghz band, I did a quick test with my BT music receiver (BT 4.0) and switched to my 2Ghz wifi AP I didn't notice any interference, I'll test my ps3 controller later when I get back home to see how that functions.
BTW I suggest keeping it on 5Ghz if you have an 802.11AC router since you can get a link rate up to 433Mbps , N networks only connect at 150Mbps with this tablet .

So I have a issue, I experience buffering when I try to stream audio via Bluetooth To my Philips fidelio while on wifi. If I turn off Bluetooth the buffering goes away. Can Bluetooth and wifi not be used at the same time? I have a 2.4 ghz wifi router only. Also if I turn off wifi "use 4g" and just use Bluetooth the buffering goes away as well. Does anyone else have this issue?

This happens on many phones because the wifi and Bluetooth often share the same antenna since space is crucial, both operate in the same general frequency range. Not much you can do I don't think.
I wonder if I got a 2.4 & 5ghz router if that would solve the problem

i got the same problem: everytime i stream music to my bluetooth headset and leave wifi turned on my nexus looses wifi connection when the screen is turned off.

That's a great experiment to try. I remember back on my nokia n95 wifi and bt stuttered together cause they shared antenna. But surely 5ghz has a desperate antenna? Curious.
I have the same issue. If I keep the screen on it doesn't buffer. The best solution I have found is to put the phone in clock mode so you don't get screen burn in. I used tasker to setup a profile when the phone is plugged in.
I haven't tried the 5ghz wifi but heard that works. My phone sees my 5ghz router but it won't connect. I tried all the channels but I guess that's a different bug to sort out.

Just tried this and it seems to be working for me as well ... Thanks for your help
Did you try setting your phones wifi to 5ghz only in the advanced setting ?
I think Franco kernel updater has a setting to fix this.

I've noticed that when streaming video over HDMI with my Bluetooth mouse paired, it sometimes gets choppier than when I turn the mouse off. Similar effect I guess.
If screen on fixes this than that's a different issue than antenna sharing bandwidth problem. Sounds more like the android 4 power reduction bug kicking in throttling the CPU or data or something.

I tried that and it still won't connect although it sees the 5ghz. Not a big deal because the range on my 5ghz sucks anyways, i just wanted to try it and see if it fixed this issue.
I got the Phillips speakers as well. I'm a little disappointed by the slow charge and low speaker volume for the price, but it works.
I did an alternative setup for my dad with a pair of cheap computer speakers from Walmart and Bluetooth dongle from Ebay. I also got a desktop cradle with spare battery slot that does a fast charge. In total it ended up costing a lot less than the Phillips speakers and probably sounds better.
So I'm on official cm 10.2 and I have a problem where if I connect to a Bluetooth device my WiFi goes to crap. I've done a full nights research on this problem and apparently its pretty common post android 4.2. The only fix I have read about that seems to work for people is to get a duel band router and run 5GHz WiFi. So before I go buy yet another router to try to solve this problem I would like to know if any of you have run into this problem as well, or do not have it at all, or any fix other than the 5 GHz router? Is stock ROM having this problem as well? PA?
Thanks in advance
Your Bluetooth must be on and connected and in some cases you have to run speed test.net to see it get slow but mine simply loses signal after I try to surf. Or gets so slow as to be unusable. I'm streaming audio to a Bluetooth headset.
Most devices behave this way because bluetooth is also on 2.4ghz as well. A modern inverter style microwave oven in the kitchen can also FUBAR WiFi too because they also operate in this band. If you are that heavy of a user 5ghz would probably help...though keep in mind 5ghz doesn't travel as far.

I have the same problem with Nexus 7 android 4.3 but not with my LG optimus L9 android 4.2.2 phone. Wifi and Bluetooth both works fine with the phone but not with Nezus 7
Update: I solved my problem by buying a 2.4Ghz / 5Ghz dual band router.
Whenever I have both bluetooth enabled (and paired with any device) and wifi enabled, and I'm streaming music (Spotify in my case), after several minutes (almost randomly), the internet will stop working. Meaning, the WiFi icon will still show as connected, but it can't connect to anything online. I typically have to disable and re-enable WiFi for it to work, but then it would do the same thing again.
The strange thing is, my Galaxy S4 had the exact same issue/behavior. On both devices, I've seen this behavior regardless of the type of WiFi connection and/or bluetooth device (I've noticed it with my skullcandy headphones as well as my Sync in my car).
Do these devices share the same bluetooth/wireless chipset? Is it an Android thing? I'm forced to either use 4G with bluetooth, or WiFi with wired headphones. Thanks.
EDIT: this is using 5ghz Wifi.
What version of android are you on ?
carrier phone or unlocked. Some times these issues are carrier specific and non existent on others.
If you go into settings - wifi
Uncheck any option that says switch to data if wifi is unavailable.
I can confirm that this is an issue, I experience the same problem on my g4 818p

WiFi goes on 2.4ghz or 5ghz(most commonly on 2.4ghz) Bluetooth works on 2.4ghz. Unless you are 1m from router, BT is going to butcher your wlan. Had the same problem before. Solved it by buying dual band modem-router.
You could forcing different channel in wlan settings.
http://smallbusiness.chron.com/fix-bluetooth-wifi-interference-71008.html
idea here is reducing interference to bluetooth from competing sources.
- switch off wifi and use data which the OP is doing. Curious that the problems occur even at 5Ghz. Would have thought that band would be relatively immune to 2.4ghz sources.
- reduce the distance between bluetooth device and phone.
- move away from any sources of wifi interference if wanting to use bluetooth.
And now from the ppposite direction. Preventing bluetooth from interfering with wifi

Read the comments below. similar to the OP.
The key is more management of the problem rather than solution.

I'm using the Verizon variant.
this issue hunted me on all software version
Many options live
Router: Try another chanel
Router: Try only 2.4 or 5 Ghz
Router: Try only N or try only b/g/n mixed
App: Delete tunin radio
Last options send back service mainboard change.
i m facing the same problem but only when i do cellular call,
i am using realme wireless earphone , when i used to call my wifi speed gradually decrease , and after that stop working completely..,
after disconnecting the call i need to OFF and ON to work wifi again....,
My wife got the same issue with a Samsung A40 (and before with a Motorola), when using 2.4 wifi and Bluetooth connections (band and speaker for instance) the wifi is hanging. With wifi 5 it's ok. I don't have any issue with my phone using same network. It's crazy.
I wonder if anyone can advise how this problem might be fixed:
I have a fire-tv stick in my bedroom the latest version which has a voice remote and connects using WiFi direct instead of bluetooth. I'm using 2.4Ghz wifi (using a TalkTalk hg633 super router). I can't use 5Ghz because the signal to my bedroom isn't good enough on 5Ghz. On 2.4Ghz the link score from inSSIDer is 91 with the fire-tv stick unplugged, with a signal of -50dBm. With the fire-tv stick on a WiFi Direct AP appears on inSSIDer with a signal of -39dBm (ie stronger than my normal wifi signal). The link score drops to 71.
If I test download speeds and pings, then with WiFi direct off, i get decent downloads speeds (around 20Mbps) and 18ms pings in my bedroom, in the lounge its a little higher. With Wi-Fi direct on, download speeds drop below 7mbps, sometimes 1mbps, pings increase to 200ms (although I have seen 10,000ms) and the connection often disconnects so the download speed test or ping is unable to complete. (I get about 2 tests that work out of 6, the others fail due to connection issues).
The upshot of all this is that I can't get a reliable streaming service on my fire-tv stick. especially in the evening. The network often disconnects, or slows to a crawl so I get frequent buffering, inability to stream at all or a poor quality picture. In the lounge, I often find my PC disconnects when wifi direct is on though streaming is less of a problem (because there the wifi signal is about 5dBM greater than the WIfi-Direct signal
I contacted amazon, and they suggested changing the channel of my wifi so it isn't on the same channel a Wifi Direct. That doesn't work because the WiFi Direct signal follows my wifi onto the same channel.
I can't use a lan cable (no option for this on a fire-tv stick, and I shouldn't have to in any case). I don't want to add extra extenders / APs to my wifi network as that might just make things worse.
Does anyone know of any way to switch off WiFi direct and use bluetooth for the remote or the FireTV app on my phone instead? Or to decrease the power of the wifi direct signal, or any other solution?
I wonder about switching to an older fire-stick with bluetooth remote - but that I think would mean I lose the voice search facility?
If I swapped to a full Fire TV with voice remote - do they use bluetooth or Wifi Direct?
Same problem. Not as dire a situation because it's in my kid's bedroom and not mine. :silly: But it interferes with the WiFi signal in areas that are closer to her room than my home router.
Not sure why AMZ chose to use the same channel as the FireTV stick talks to your WiFi network on to do their communication to their remote. That seems like a really bad design - if it's messing the 2 of us up, it has to be doing the same for a whole lot of people.
I tried changing my home WiFi from channel 11 to 1 in troubleshooting and had the same experience as you - the FireTV stick's WiFi changed right along with it to continue to clobber my home WiFi signal. Been through the menus in FireTV stick - no way I can see to change its behavior. Google search led me here.
Hi,
Whilst I stand by everything I said, in attempting to get Amazon to replace my remote with one that used bluetooth instead of wifi-direct, they sent me exactly the same remote in replacement. It still uses wifi-direct. However, it has worked fine, despite being on the same channel. That suggests that some remotes are faulty and causing or exacerbating the problem. Exactly why that would be I don't know, but it's all working fine for me now.
Roku has been doing this for years Here is a link to there form maybe amazon will listen I just got a new one for another room but no network problems and is faster on menu loading so I can live with it.
You're always gonna have problems with a ton of stuff on 2.4ghz. If your router has 5ghz, I would recommend reorganizing if possible, or getting a stronger router. 5ghz means no headaches, no problems with other things, controllers\remote work fine, etc.
Hi!!
I just bought a new tab s4, and I can not connect it to the 5ghz wifi network. It connects, but says connected without internet. The 2.4GHz network connects perfectly.
PS. Sorry for my English.
Same issue.
My tablet is TIM branded.
Same issue, it connects on 2.4ghz but not on 5ghz...
Anyone?
HI peep's mine is connected to 5 GHz and it’s working flawlessly, it’s showing a connected speed of 866MBPS!
Quick questions, did you try a reboot router and Tab S4 once connected to 5GHZ ?
Also are you using separate WPA2 PSK key ?
As some routers can’t handle separate keys, keep the Wi-Fi key same for both channels i.e 2.4GHZ and 5GHZ!
Does it get ip address from the router/dhcp server you have?
I don't have access to a 5Ghz wifi right now. Next week I'll try the tablet and I'll try everything you said. If the new tablet has the same problem of course, I hope it goes well.

I have the same problem and I noticed that it came with the Anroid Pie update! 2,4G is working fine in my S4.
I have another tablet Samsung Galaxy Note 10.1 2014 edition and 5G Wifi is working flawlessly.
Might it be software issue in Android 9?
My basebandversion is T835XXU3BSF4, kernel 4.4.153-16124683 #2 Fri Jun 14 2019.
My Tab S4 was ,finally, updated to Android 9. 5GHz working fine. Both 5GHz and 2.4GHz working fine...
All good here...
I got one coming in the mail and will report back on my success but if you don't get internet trying setting your dns manually to Google's public one for testing. 8.8.8.8 Could also be related to the channel the router is using for 5ghz.

Okay, so I got a new tab s4, and I have the same problem. At the second floor of my house, I don't connect to the 5Ghz wifi. I have separated bands. I tried changing the channel... I don't know what else try.

5GHz WiFi has less range than 2.4GHz, maybe the signal strength is not enough at the second level. Use the lowest frequency band available, move the base unit to a place less obstructed etc. This does not sound like a device issue.

Yeah, I know, the device issue is that all my other phones, computers and devices are able to connect to the wifi. I enabled the smart wifi and it looks like it's going better, the tablet is able to get better download speed.
