SM-T520 Wifi issue - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

Hi, I've tried all the troubleshooting steps on how to fix wifi connection but it seems there's no luck.
I've already change the firmware but still no connection.
The problem is, I can connect to a wifi but it has no connection. It will only "saved,secured" and that's all.
Anyone can help?

Same issue here.
I'm starting to think that the eletronics trash can is the solution...
My Samsung Galaxy T-520 detects all Wi-Fi networks, but it doesn't connect to any. The status shows "saved, secured", but it fails to connect. I tried everything, switching on/off passpoints, bluetooth and whatever, even factory resets (twice). I also tried to start the device without the Google account, skipping everything. I also tried a cell phone access point, it's all useless. All my other devices work, so it's not the router. Maybe it's a hardware problem. It suddenly stopped working

TouchPro Wifi loses connection :-(

Hi friends,
I have a terrible problem with my fine TouchPro2.
It constantly loses the wifi-connection. My old TouchPro1 never had these issues.
I have the actual HTC stockROM installed. Tried WiFiMonster - but again. After a few seconds it loses the connection.
Sometimes I'm able to download three, four mails, but then it breaks again :-(
Any idea?
re
To be more specific: WiFi goes off after 30 sec. or so. :-(
does wifi turn off? or simply disconnect? if it's disconnecting, first thing i'd do is reboot my router with wifi enabled on the phone and see if the connection improves. if wifi is physically turning off i'd guess it's an issue in the rom. maybe try another rom? and make sure wifi is set to "best performance" on phone.
Is this everywhere or on a specific router?
Does your connection drop after a certain activity (e.g. screen going into standby, opening a specific program, etc.)? Also, have you tried to backup your device and perform a hard reset?
Similar Problems
I've been having similar problems for about two weeks now.
I have tried several things like hard reset, soft reset, changing the rom, playing with the wireless connection and just about everything in the connection folder but no.
I my case, when I turn the wifi connection on through the comm. manager, it slows down the phone while its trying to connect and then it just goes off, leaving me with t-mo data connection. However, when I turn off data connections in comm. manager, it connects to the router and stays connected but it does nothing with the connection. Meaning, I am connected to the router, but somehow I won't be able to use the connections.
If anyone have any suggestion(s), I would greatly appreciated it.
solved...
Thx guys,
I performed a Hardreset and testet one by one the installed software... and found it: I installed a CommManager and it caused the WiFi-Problem :-(
thx

What do you mean "slows down the phone"?

If your wifi connects but you cant get out, check to make sure you don't have the proxy box checked in connection settings. I have seen this box mysteriously become checked in the past.
Just a little comment
I will be getting TP2 very soon, but speaking of WiFi problems in general..
I had 3 phone: TyTN II, Samsung Omnia & iPhone 3g. only the TyTN could connect to WiFi at home while the other two can connect but will not get any data... however, they worked flawlessly in numerous other locations...
the problem was with my linksys router
apparently some older routers not compatible with the newer devices...
just wanted to share
Ok. As of today, it seems to be working, thanks for the help. However, I think it might have been my router. I think it had something to do with overheating because I put my modem on top of it. But the funny part was, everything, with the exception of my phone, was connecting. However, the connection was never really strong or reliable.
Anywho, thanks for the suggestion, even though it didnt really help me, I appreciate the gesture.

[Q] Defy loses internet connectivity via WIFI hotspot.

Hi All,
I am trying to share my laptops internet connection with my Defy via a virtual miniport adapter(using a program called connectify)...my phone gets connected perfectly and I am able to surf the net on my phone..but only for a short time. After a while if I just let the phone be on standby for a while, it loses the internet connectivity. It remains connected to the hotspot(on my pc) but somehow there is no internet on the phone anymore. However if I turn off the wifi on my Defy and put it back again, the internet is back. I have tried almost everything but nothing seems to work. Initially i thought the problem might be with the connectify software on my system so tried using other softwares such as virtual router intel mywifi technology etc. I even tried to create a virtual wifi miniport manually from the command line but same problem everytime. I tried to change the wifi sleeo policy in my phone to never and that did not help too. I am running stock Froyo on my Defy. Sometimes when I turn off wifi and turn it back on it wont even connect to the access point, keeps showing scanning...connecting...scanning...connecting...then finally disconnected. I just cant understand what is wrong. If someone can throw some light on this...it would be really helpful, its almost 20 days since I am breaking my head over this.
Thanks
this might help
Install connectify and select wifi security mode as Ad-Hoc,WEP,this worked for me the defy sometimes seems to have a problem with WPA2.

Strange WiFi problem

Hi! recently my phone won't open google, facebook and a few other sites if I'm connected to wifi, but the other sites open without any problem. And if I restart my phone, and I use 3g only, it opens anything just fine.
Router: linksys wrt160nl (DD-WRT r19342)
settings: bgn enabled, wpa2, tkip+aes
My phone has the latest rom (xxlm9), tried to reflash, reset everything, but nothing worked. Oh and on pc these sites over wifi opens without problem.
Any ideas?

[Q] Wi Fi Connectivity

Hi all,
Lost info for my original account, so I made a new one.
Straight out of the box my HTC One has not been able to connect to my router. It gives me the message that it's avoiding a poor internet connection although under the connections it says the signal strength is excellent. My laptop connects just fine. My Razr HD connects just fine, but interestingly my wife's galaxy S3 will not connect either. It gives her the same message.
I've tried changing the bandwidth from auto to 2.4 to 5. I've tried forgetting the network. I've tried static internet connection with IP address 192.168.0.15 and also 10.0.0.11 I enabled the DLNA, there is no useable option to clear cache or clear data and last of all I did a factory reset.
None of these worked. DLNA and the static internet connection have allowed me to connect, but it's not really connected. I'm not sure what's happening. It says connected with excellent signal strength, but nothing connects. No internet, no netflix, no nothing.
I think it might be something to do with the router itself, but I don't think I'll be able to get any information from netgear's people. It's not broken (other devices connect just fine) but these newer smartphones seem to have a problem with it.
Neatgear N300. Also, I tried WPS connection as well. No Dice.
Thanks
Update-I've found a -similar- issue in this forum regarding specific bandwidth connectivity issues for dual band routers. One of the suggestions was to update the firmware. I haven't been able to do this successfully. Still trying.
Update 2-Tried to connect to Safeway WiFi today. No luck. It goes to the sign in page and it's just blank. At home it says the page is unavailable. At safeway it's just blank...
*bump* No help at all?

[D855] WiFi unavailable

Hey I got some problems with the WiFi connection, it connects but it says internet not available, although the wifi network is working in other devices. I tried doing a full wipe or flashing a kdz, but still have the same problem. Have u got any ideas to resolve this? Thanks
I'm having the same problem. I don't know if it's like this for the OP, but the hardware itself seems to work. It detects connections just fine, I can install wifi analyzer and it displays and measures all nearby connections no problem. However, when I try to connect to wifi, it says "saved. secured." It won't tether either. I've tried with multiple modems and routers, it just won't connect.
