Weirdness when using wifi hotspot tethering

Hi all I'm hoping you can help me.
I have the R800a model of the Xperia Play, running 2.3.4, stock standard and not rooted.
I'm experiencing some very strange behaviour when I turn on wifi hotspot tethering on my phone. When I do, it seems some 3G functionality in the phone is lost. I can still browse the web in Dolphin Browser, but TuneIn radio stops working completely, saying there is no connection. As soon as I turn wifi hotspot off, it picks up the connection again, but if I turn it back on...bang, drops out.
For the record, devices connected to the hotspot, such as my Nexus 7, can access all online functions, including TuneIn radio. It's only the phone itself that seems to lose this functionality.
It seems unlikely there is a bug in TuneIn radio, because I've had a friend verify that it works on his HTC phone when wifi hotspot is on. I haven't verified if it's happening within any other apps but it does look like the inbuilt wifi hotspot functions in this phone are blocking some 3G connectivity while active.
This one is stumping me. It's quite annoying me because I enjoy listening to the radio on the train, but I can't do it on my phone if I'm browsing the web on my Nexus 7.
Does anyone have any clue about what's going on here?

So I've found it's not just wifi hospot tethering, but tethering in general, as USB tethering does the same thing.

So I've gotten around this by setting up Bluetooth tethering instead, which took a bit of fiddling but seems to work much better.
I have a feeling Telstra's software was probably blocking some functionality while tethering via USB or WiFi.

Intermittent WiFi Dropouts?

I got a Tab S 10.5 a few weeks ago as a replacement for my Nexus 10. Overall, I feel like the Tab S is head and shoulders above the Nexus - but I've had some strange issues. I've had the wifi signal intermittently stop responding - it seems to be more prevalent on my 5GHz network using 802.11ac speeds but I've experienced it at standard 2.4GHz connections as well.
I haven't rooted the tablet yet. I thought at first it might be my wireless network as I hadn't used any other devices that were 'ac' capable even though I have a pair of Netgear R6300V2 routers bridged across my home. However, these wifi signal dropouts persist only on the Tab S - if I turn wifi off, then back on, connectivity is restored. My Galaxy S4, Chromecast, PC, DVR, all stay online just fine.
Has anyone else had this issue? I got my Tab S with the Samsung Book Cover - which I love, but it almost seems like it happens when I hold the Tab a certain way.
Thanks for anyone who can give any feedback.

Did you connect your Tab S with your S4 through SideSync at one point?

Yes, I have used Sidesync. I disabled remote notifications, but occasionally still get a pop-up that remote notifications are enabled even if I haven't used sidesync in days.

I too suffered wifi drop-out and Bluetooth issues. Following this thread (http://forum.xda-developers.com/galaxy-tab-s/general/heads-sidesync-bt-wi-fi-bug-t2828911) I realized that there is a problem with SideSync. Even when not connected it sitll tries to communicate with the tablet and affects the wireless components. I removed Sidesync from my Note II and clear the data from SideSync on the tablet and for the past week I have not ahd any issue with Wifi or Bluetooth.

Thanks. Side Sync Sux.
Brilliant. Thanks. I was having a big problem with 2.4ghz wifi. I though there must have been some interference. 5g was fine. Tried chaining channel and all sorts. Would have thought it was my router but I have two with same prob just on 2.4ghz. It was happening to my phone and tablet, but then noticed only when the table was connected to wifi. Just disabled Side Sync and now the wifi is blazing.

Hi
If I understand correctly the wifi will only work if the phone is close by
I read elsewhere that other smart watches will connect directly to wifi
even if the phone is not on
can someone please clarify & will this option come with future updates ?
Thanks

The phone needs to be only in a close range if you're connected by Bluetooth. If you're connected to a WiFi network, the phone just needs an internet connection and can be on the other side of the world.

Thanks Foo
But it doesn't seem to be the case with mine
If I am at home or at work it will connect easily with the Wifi but only if the phone is there
without the phone its saying disconnected , maybe I am missing something

I did a test recently with mine. I left my paired smartphone (Smartphone_A) far out of range of my watch (>100m within a company building). The watch signaled that it is disconnected as it was only connected by Bluetooth before. The smartphone itself was only connected to a 3G network (no WiFi active).
I used a second smartphone (Smartphone_B, obviously not paired with the watch) and activated the mobile hotspot on it. I connected the watch to the mobile hotspot using WiFi and was able to connect to my paired smartphone:
Code:
Watch<---WiFi<--->Smartphone_B<--------->3G mobile data<--------->Smartphone_A
<--------------------receive notifications-------------------------->
I was really surprised that this worked, but it did, so I'm pretty sure, that they do not have to be both connected to the same WiFi or be within a close range.
The question is, why is it not working for you. How do you check, that you are connected to the WiFi?

Strange
with my phone on no problems it shows my house & work network on the watch & connects showing the correct SSID
with phone off I tested it 2 ways 1 clicked on google app (disconnected ) 2 Settings- About -Connection (disconnected )
Brgds

I see the problem, I also may have misunderstood the actual problem.
The status (Google app/about) which you are referring to shows if you're connected to your watch. If your phone is off, the watch can't connect to the phone. Even if the watch is connected to your WiFi, the watch will not go directly to the internet, but will use the WiFi connection to connect to your phone (cloudsync).
You can check the WiFi connection in the WiFi setting. See if the watch was assigned an IP address, if there is one, then you're connected to the WiFi.
I think you expected that the watch can directly connect to the internet and use things like Google now directly. but this is not possible.

Yes
I checked a few things, my phone was on & the google app works, turn phone off & the google app says disconnected
in wifi settings even with phone off it says obtaining IP then connects so I thought it would connect to google app
so if I understand correctly it wont connect directly to internet but the phone (cloudsync) even if the phone is on or off
Thanks for taking the time to clarify

all seems a bit pointless to have a wifi connection but cant really use it do anything
maybe some apps or updates in the future that will utilize the wifi option ??
Thx

I guess wifi is just helpful if you get out of range of the Bluetooth connection.
At home I often get out of range of the Bluetooth connection so the watch connects to my wifi and reconnects to my watch via cloudsync as long as I stay out of Bluetooth range.
When the watch gets back in reach it connects via Bluetooth again, because this is much better for battery life.
So wifi is only there to increase range but unfortunately not for standalone functionality. I also have a Youtube client and a webbrowser on my watch (just for fun, not really useful). Both apps also need the watch and will not use a direct wifi connection to load videos/websites from the Internet.

Wifi loosing connectivity (H815)

This has been plaguing me for a while and it's making me hate this phone. I've also seen this issue pop around the internet so it's not just me.
What happens is the wifi stays connected to the router but has no connectivity (i've tried pinging the gateway when it happens, the connection is dead although it is listed in the router as connected). And it happens totally random, sometimes it works entire day, sometimes it happens every hour or worse. This seems to have gotten worse with MM. I used to be able to fix it with turning wifi off/on but now even reboot wont help (it connects to the router but immediately says no internet on wifi), i have to reset wifi on the router for it to start working. I have 2 other androids (kitkat, lolipop), an iphone 5, tablet with a hybrid OS, 2 laptops and a desktop on the wifi working without issues so that kinda rules out the router as the sole culprit (it's a Technicolor crap from my ISP that i can't change, i can only buy an additional AP but i have no idea it will help). Ofc, when the connectivity is lost, the phone is still connected to the wifi, hence doesn't switch to network and i stop receiving notifications, which is driving me insane (also a work phone).
I recently installed an app ("wifi connection manager", the app itself is fairly useless, half the stuff doesn't really work that well, and all the options are really things you can do manually) that has a background service that i thought would keep the connection alive. It worked for about a week and then all of a sudden it stopped. I've tries everything else, short of reflashing the phone.
So after ****ing around for the 1000th time, trying to figure it out i realized that turning the WMM off (router QoS) stops the connectivity issues. Problem with this solution is that my download rate over the wifi drops by half immediately (from 50mbit to 25) and after a while all the wifi connections start to deteriorate to the point where it becomes painfully slow. What's more puzzling however is that when i do turn it off, the G4 connects via 802.11g (and for some reason this makes the connection not lose connectivity). Other devices connect via 802.11n whether WMM is off or on (except the desktop, which has an old wifi card, also on 11g).
Sorry for the wall of text. This and the anticipation of a bootloop is making me seriously regret my purchase.
So my two questions are:
1. Is there a way for me to force the G4 to connect via 802.11g even when WMM is On ? It obviously chooses how to connect on it's own.
2. Given the history of events, is there a network guy somewhere here that could identify wth is going on ?
Thanks a lot for those that made it this far

Can't share Data from Android device using bluetooth tethering

Hi folks,
I've got my Xiaomi Mi 9 SE (Global Version) two weeks ago, and I'm very happy with it. There is only one problem:
I can't share my Data Connection via Bluetooth! ..
Neither with my car and its bluetooth speakerphone, nor with my Smartwatch, I can't get managed to share the connection.
So the Bluetooth connection itself is up and running without any problems! Only the data connection is not shared. The car shows me no signal (general network), and the SmartWatch does not get a connection to the Internet.
I looked up the Tutorial here in the old en.miui-Thread but I don't get the "Enable Internet Access"-Button in the paired Device Menu (part#6/7 in the Tutorial). I've activated the Bluetooth Tethering mentioned in part#5..
Is there any other way to share my Smartphone Connection via Bluetooth to paired Devices?
I've re-paired the devices multiple times. I also have done a factory Reset with Phone and SmartWatch. The problem occured with original Global Rom, and still occures with latest xiaomi.EU Rom.
Hope you can help me..
Best Regards

Some news: Occasionally it works. Sometimes I can access the Internet with my Smartwatch, which is connected to my smartphone via Bluetooth. But really rather rarely. And even without me changing anything. I don't even touch the smartphone yet, and suddenly I have Internet access on the Smartwatch, 2 minutes later but then again no more. Damn weird.
EDIT: Solved it! You have to set every Priority for the Wear OS Notifications in the App Manager to "High" and allow everything for this App.. Now I have continous Data Connection via my SmartWatch, Problems are gone
