No connection after Wireles Projection - Huawei Mate 20 Pro Questions & Answers

Hi,
Every time after I succesfully connected Wireles Projection, finished it, close it, disconnected from wireless display, ... I have no connection at all. I must restart my phone after every Wireles Projection to get online again. And without sign of anything wrong, everything seems to be connected, but if you try to connect to smart home device, Internet, mail client ... No connection at all. And after restart everything is back to normal. It happens at any place, home, work, ... Has anybody same problem?
Thanx

I have not faced anything like this but was facing the issue of continuous toggling between wifi and 4g causing timeouts when trying to access local resources on my home intranet. Initially I tried formatting cache and also factory resetting the phone which helped but not completely. Finally found out that disabling Adguard DNS resolved the issue completely.

[Q] While connected through Wifi, Opera does not connect

Apologies if this has been resolved eslwhere, but I did a thorough search and I could not find the solution in similar questions asked for the exact problem I am having.
I have an HTC HD2, basic Rom 1.66.405.2 (76641)with Max Manilla, Radio version 2.06.51.07.
I have previously used Opera 9 and Opera 10 to surf the internet along with Skyfire with no problems when using the 3G connection or when connected to my home or work WiFi, until a few weeks ago. When connected through WiFi, having changed nothing on the network routers or my phone, I just cannot get to pages. The same is with the facebook app and any updates via weather or stocks/shares.
It seems that as soon as WiFi is connected there is no data connection.
I have checked data connection and it is OK, I have also tried the slider the best as suggested on another forum, even re-installing Opera 10, to no avail.
I am considering switching to Energy Max Sense at the moment but hesitating as I can't bear going through another hard reset and re-installing everything, but this issue might just force me down that route.
Any thoughts before being forced down this route?
Been through lots of different settings and basically it appears that once wifi is connected I lose all data connecions, nothing then connects.....Please help?
Did you ever get this fixed, because I am now having the same problem.
I used to get internet data connection via wifi by first turning off data connection in comm manager, then turning on wifi. I must have screwed something up, because now I cannot get any data traffic via wifi. I can't even get data from my cell network whilst wifi is on, I have to turn it off to get my GPRS connection back. Bit frustrating, been through connection setup and delete/setup network many times to no avail. What have I done... harrumph!

Why Disconnect data connection before activating WiFi?
I leave it on, still it will get data through WiFi is available.
If you disconnect data connection, you will not get data through data connection. (while you have WiFi activated, as you switch it off)
Have you tried using both at same time? Perhaps disconnecting data connection does a "trick" so you can not get data through WiFi too and you are now experiencing expected behaviour. (And that it did before was the wrong situation.)
i tried lots of stuff, soft resetting each time, I then did a full sync and backup to my home PC (work PC has firewall and stopps internet connection).
After that I did a cache cleaner and emptied a lot of trash, it did appear to be running slow. Did another soft reset and voila in the morning it was all working.
I played around with settings, double checked everything and to the best of my knowledge nothing had changed to cause this fault, so no idea if it was a problem with synching between the two PC's, work and home, or whether the cache cleaner did the bizness. Never had the problem repeat again since.
Have you tried getting settings from your provider again maybe something got wiped by accident.

[Q] WIFI connection stops transfering data

Hi, is anyone has the same problem? When I'm connected at home to my Tenda router (WIFI b/g/n) after cca 30 min. my phone WIFI stops sending and recieving data, Skype is offline, etc... but WIFI in phone is stil switched on. After I switch WIFI off and back on (on my Samsung, not on my router), everything works good for a while and after cca 30 min. is situation the same. Is there in Samsung any WIFI sleep mode or something like that? Or some settings, which is not visible? Any other suggestions? Sorry for my poor English. Thanx in advance.
I'm having the same problem. But I did a factory reset and it works fine afterward.
And just few hours ago, I encountered this problem again. What did to get this error was, I pressed "on samsungapps" and it failed to update and thus results wifi connection stopping. What about you? Also my Kies air is not working.
are you guys sure you have wifi sleep policy set correctly? just to be sure, settings, wireless, wifi, menu button, advanced, wifi sleep policy to NEVER.
Yes. And also even if i manually disconnect and reconnect the wifi back. The data still doesn't come in. It is stated there as connected but no data at all.
Somehow Wifi keeps searching every few seconds, even thought it's connected.
This is bound to cost in battery life too.
I have reseted router to default settings, disabled n mode, disabled security (only mac filtering is on), disabled all unnecessary features and PROBLEM IS SOLVED !!! Thanx God Tomorrow I will experiment with router settings to know, what was causing this error ;-)
Well at least u're connected, I'm facing the same problem as the thread starter. No data flow at all. Browser showing me offline msg. I had the same problem on the 1st day with the phone after I woke up. previously playing with most of the default aps. So i'm not sure what went wrong, did a factory reset and it works fine.
Until, few hours ago, I tried my kies air which didn't work. Browser couldnt load the address given. And I thought i had an outdated kies air, so i went to click on samsungapps, which failed to update me. At that point the wifi is still working, i leave my phone for about 30 mins, and when i came back. The same problem which happened on the 1st day came back. I was hoping to find an answer here so I didnt do the factory reset it. On another note, the phone wifi works after restart, but wouldn't last.
Edit: The wifi works after i resetted my modem to default. oh well. at least that solved it.

Hi,
Did you find out what setting was causing the connection issue? I also have this problem with my Tenda router. I thought it might be the wireless N, but disabling that doesn't fix it. I have a wireless distribution system set up with other tenda routers so didn't want to disable all the settings to troubleshoot if i can help it!
Thanks

I have the same problem, my router is N and the conection between SGS2 and my router is bad. Any idea?
Same problem here, I'm running WZR-AGL300NH in access point connected to my Ubuntu Server. Everything else works in the house just fine but SG2 stops transmitting data after a while.
I recently upgraded to KF1 firmware (and unknowingly wiped out whole phone, being on the bleeding edge and that didn't seem to help.
I would very much appreciate all tips because this problem is very annoying!
Additional Info:
- Buffalo is running latest firmware
- Authentication WPA2-PSK
- Encryption AES

Same symptoms here. Cisco DDR2200. WPA2 PSK. Haven't tried fiddling with the router yet.
This seems to be a common problem. Anyone knows of a definitive fix?
Bump...I have the same problem and the issue persists even after i reset the phone

Glad I found this, thought it was the ROM I had flashed to the phone (which is VillainROM)
I keep losing connection from my phone via wifi like everyone else in this thread
edit: I've just assigned my phone an IP address via my routers settings and I can connect to the net again
Also when it wasn't working, I couldn't ping the phone. When I assigned the IP just now I still couldn't ping it.
When I did a tracert to it, I could get to it when the IP was assigned and when it wasn't.
I have no removed the assigned IP for the phone from the router. Wifi connection is still working after disconnecting/reconnecting wifi on the phone.
I can also now ping the phone, where as before it was getting timeouts.
Also when it wasn't working the first time when I did a tracert it was showing up as HPsomething (didn't make note of the numbers)
this time when it is working it's just showing up as the IP address when doing a tracert.
Another update:
Just checked my printer, it has an IP address manually set on it, which at one stage when the phone wasn't working for internet it had the same IP as the printer, hence when tracert'ing it I was going to the printer instead of the phone and getting the HP etc back.
When it wasn't working at that time and looking at my routers DHCP list, it had the MAC Address of the phone against the IP that the printer has....
So I've got some issues with how my own network is setup ^_^ which looks like is causing me grief.
So the issue is with DHCP? Setting a static IP fixes it? I'll have to try, but I doubt this is a problem with the network, as all my other devices use DHCP without this problem.
I have the exact same problem!!
It's really annoying.
i was having problems with wifi too.. it keeps scanning and checking, etc, signal dropping for no reason..
fixed mine..well for me it worked
backup ur phone ( i dont take responsibility if ur phone catches fire or dies or chases u around )
u need to be rooted
download FXR WiFi fix and rescue from market
and just run the app.
now my wifi signal stays constant speed and i get good speeds
alternatively try
WiFi Fixer
both of them will cause high battery usage..i think since it keeps the signal at maximum.. so only enable wireless when i need it or use juice defender or green power.
greenpower seems great. using this at the moment

S3 not automatically connecting back to WiFi

I’ve recently upgraded from an S2 to an S3 and have a slight issue. When I’m out the house and connected via a data connection (O2 giffgaff) all is great however when I get back home or to a saved wifi spot my phone will not automatically connect to it whilst the screen is off. I have to litterally wake the screen from sleep/lock mode to the home screen where I can see the data connection still on then soon after it will switch to WiFi with the connected confrimation message.
Surley I shouldnt have to wake my phone when coming in range to a saved WiFi point in order for it to connect to it, my S2 never had such issue and automatically connected to saved points. Earlier I went down to the shop and used the data connection whilst there, come back to work and hadn’t woke my phone for about half hour, turned it on and it started connecting to the wireless. The connection still works when the phone is in sleep/lock screen as I still recieve emails etc so it's not cutting of data connections completely when sleeping so I'm a bit puzzled by this, I haven't tested this vice versa WiFi to data but I'm sure there must be a simple setting somewhere.
Any help greatly appreciated.
I noticed this earlier on, I was out all day, returned home and wifi wouldn't auto connect, I had to disable and re enable wifi
Sent from my SGS3 on Omega v9.0 using XDA Premium
It's strange I can't quite work it out, I tested it the other way round and it seemed to automatically connect to mobile data when there was no saved WiFi in range so it only seems to be an issue with auto connecting to WiFi.
I'm going to try a few more tests.

You could try deleting the saved network and adding it again. It has happened to me before and that has fixed the problem.

Help with wifi on tablet needed

Hi,
I have recently bought a NATPC M009s with ICS on it. I'm completely new to android!
I'm having problems getting it to connect to wifi at home and wondered if anyone can help.
I have a BT home hub 2, the tablet will see the network and allow me to enter the wifi password but it then sits saying 'saved, secured with WPA' and no matter how many times I press connect it won't. Apart from very occasionally it will connect but there is nothing consistent as to why it suddenly decides to connect!! Other laptops and phones connect to the home hub fine
Things I have tried:
Setting a static IP for tablet on the home hub
Rebooting router and tablet
factory reset on tablet
factory reset on home hub
Downgrading to gingerbread (failed as the instructions on how to do it didn't work!)
Tethering tablet via wifi to my iphone (connects no problem)
Searched forums for previous posts with similar problems - no luck!
Does anyone have any suggestions on how to get it connecting reliably?

This is really odd, I suggest you try to very temporarily turn off password protection on the WiFi network, just to see if thats what is throwing it off.
WiFi can be an oddball and doesnt confirm to logic.

Hi,
Thanks for the suggestion. Tried it and with security off the tablet connected (after 2 attempts - failed to get IP address on the first one).
I then put security back on, it connected once!! It then dropped the connection and won't connect again.
Arrgh! So frustrating.
So does this suggest that the security is the problem.... I don't know.
Any other thoughts?

Sounds like a defective WiFi hardware. You get a too low signal reception and/or transmission, corrupting most of your frames. Try placing it as close to the router as possible and see if there's any change. Or get the unit replaced.

[Q] Connection issues

Hey everyone, I got myself a Z2 recently and have been very happy about it for the most part. However, some things seem to not function a 100% the way it's supposed to.
Some times after it's been to sleep and I try browsing online with it using either 3g/4g or wifi the phone says it has a connection, but nothing loads. All I have to do to solve this is to refresh the wifi/3g connection manually, and then it works. It's rather annoying to always go through that procedure every time I want to use my phone, so I'm wondering is there anything I can do about this? Or anyone experienced anything similar?
Vegard
I have the same issue with WiFi while the phone sleeps or is active (no probs with mobile data though!), but I was not able to determine whether it's my router, the phone, or a combination of the two (though I have a hunch).
When I'm in my room which is unfortunately the farthest from the router, and the connection drops, my Z2 is not able to reconnect on its own. Have to disable/enable WiFi or else it's stuck in an infinite loop of connecting and obtaining an IP.
Now, I'm fine with a dropping connection occasionally given the distance and the... quality of my router. However, my laptop is able to reconnect automatically.
I have tried lots of possible solutions: WiFi sleep policy, static IP or DHCP, disabling/enabling WiFi optimisation or Auto-IP, switching WiFi channels, and various WiFi fixer apps. Nothing worked.
My guess? There is a bug in the stock firmware that makes the phone unable to reconnect if a connection is forcibly dropped . Pair this with a crappy router and you have a recipe for inconvenience.
Unfortunately, I have no spare router to confirm this, and with the bugs in CyanogenMod I am reluctant to flash for now.
Also, I am sure this is not a hardware fault of the phone in my case since I notice this behaviour at home in my network only.
Do you guys possibly know where I could find some logs related WiFi? I wanna get to the bottom of this.
