WIFI connections issues on connection and speed - Samsung Galaxy S7 Questions and Answers

Hi. Recentlly I bought a Samsung S7(G930A - AT&T version) as refurbished one. I found a big issue what hurts me a lot. Here are some issues with wifi:
I could not really connect to a lot of WIFI networks, it says "connecting" after that it drops and cycle begins once again infinitly.
On several networks it shows "authentication error occured" , although wifi is public and another devices connects to than one.
On several networks, it connects but connection is very slow(0).. only way to make a better connection, is to put phone on router...awful...
On one networks which i tried, it worked ok..it's an 5ghz wifi. although, not for a long distance from router.
I installed all updates, tried troubleshots from internet with bluetooth, reset and everything..but no success at all... Now I think that problem is really in hardware... Had anyone such issues ? Any solutions to fix ?
Please help...

I had frequent wifi connection authentication errors when connecting with my home wifi and slow Internet loading speeds with my Galaxy tablet, but all my other wifi devices connect consistently without errors.
The steps below solved a similar problem with my Samsung Galxy Note 10.1, and it might help with your Galaxy 7. Some of the steps may vary with your device, but the goal is to set wifi Poxy Settings to NONE, and IP Settings to DHCP. It completely resolved my home wifi authentication error and slow spped when browsing.
For the Galaxy Note 10.1: Settings> WiFi> long press the SSID/router name(the wifi you want to connect to)> Modify Network Config> check the box "Show Advanced Options">set proxy settings to "None" -- set IP settings to "DHCP"> Save.
Now my wifi connection with the Galaxy note 10.1 are quick, consistent, and Internet pages load fast.
I hope this is helpful.

Help please, Fuze Wifi issues

Anyone else having trouble with wifi? I have a connection to my home network and have used the 10 digit hex wep key. Even in the same room as the router (Linksys/Cisco), the signal strength is only about 50% and I can't even open a page in Opera.
SSID shows correctly
Mode: Infrastructure
Tx Rate: 54Mbps
RX Rate: 1 Mbps <-- is this the issue?
Channel 1
Advanced status shows: Associated to network.
Any ideas?

A call to HTC yielded nothing. I'm at my wits-end. Just turning wifi makes it almost impossible to load a website, I do better with just my marginal 3G service even though the wifi shows connected. Do you think a hard reset might help??

I'd also reset the wireless router too. Another possibility is there might be compatibility issues between the router and fuze. what router do you use? i'm using a linksys router and it's working fine. Obviously the signal the phone gets isn't as good as my Thinkpad's signal, but it does the job fine. I'm really enjoying this 3G speed, so I don't really use wifi that much - saves power!
only wifi problem i had was when i put in my wep key it rejected it the first time, and when i made it reconnect everything was fine. but at first it said my network was unavail.
Okay, try this - it's what worked for me:
Go to Settings -> Connections -> Wireless LAN.
On the bottom, choose the Power Mode tab.
Move the slider all the way over to Best Performance.
Fixed me right up.

I found that in a windows mobile support forum as a stated solution for anothe HTC project and tried it also, it worked!
Thanks!
I'm having problems connecting to a WPA encrypted router and it's driving me crazy.
It just hangs and hangs and hangs, but never connects. If I put in an incorrect pass, or bad info- it immediately will fail to connect, but with the correct info- it will continue to attempt to connect, but never finish.
I've changed it to "Best Performance" but that made no difference.
^ Happened to me also. Turned out that I didn't add the Fuze's MAC address to my router's allowed devices list in wireless security.
I'm having the same problems as OP. I'm using the Fuze straight out from the box and I've tried adjusting the power settings as suggested and still no luck. I've also hard resetted to no avail. Any help is appreciated, thanks.
I don't have any issues with my wireless network, but I don't use an WPA encrypted router.
I have mine set to MAC address, and it work without issues.
I have a WEP encrypted router and it shows that I am connected. Do I need to set something up in settings -> connection -> connection? All I have are Media Net and "Work" listed. Seems like no one else is having this problem =/
I'm having a similar problem with my phone. I set my phone to maximum signal and the battery is just taking a hit. I can barely get a signal although it does work. I can't get the "free" ringtone to download off of their website, but no big loss. Wondering if the 3G/Edge would be a better bet.
Im also having a problem connecting to my network. it shows that im connected but doesnt now connect to the internet in internet explorer and other online apps. ive tryed...
restarting the router.
hard reset.
changing the power settings to high performance.
disabled hidden proxy as suggested on another thread.
exchanged my phone after being suggested by htc.
im using a linksys router. is it a compatibility issue?
this is driving me crazy; why are so many people having this problem?
I dont know if this goes here, but reading your problems, I think mine is a little different.
Where I live, in Mexico, almost everyone has internet service with the same Isp, who gives 2wire dlsmodem/routers with only a 10 digits wep encription (for default), the problem I have is that whenever I try to connect to any router (I've only tried with these) it asks for the wep key, but no matter what I put it always says that is incorrect. I tried disabling the encription and IT DOES work, but I dont control the other routers wich I want to connect to..
Any Ideas?
I am having the exact same problem. I could connect to an unsecured hotspot but can not connect to my WEP protected linksys/cisco router. It appears that linksys/cisco seems to keep popping up in this thread from folks having problem. Out of curiosity what model number of linksys/cisco do you have? Has anyone figured out a solution yet?
Go to configure wireless networks than go to the network adapters tab, click the first one IEEE 802.11 bg .... and make sure its set to user server assigned IP address.
Same problem here! tx @ 54 mbps rx @ 1mbps, and it doesn't change therefore i'm getting about 5meters distance before my connection becomes unstable (WTF). Using WPA2-PSK and set to performance.
P.S. all router incompatible comments are incorrect. There's a spec for .11 b/g and all hardware should be using this therefore it should work it's either a hardware fault or some settings aren't working correctly. BTW for me it's the same prob whether changing the ROM or radio, it doesn't change...
Same problem...never resolved? Fuze $200
http://forum.xda-developers.com/showpost.php?p=4213175&postcount=19
Solution
I may have a solution, it worked for me on 3 routers so far and dramatically increased reception over distance and connection stability.
Open your WiFi router settings, go to advanced settings and look for something like Beacon Period. If I got it right, this is the interval between position updates and default setting should be 100.
If you lower this number, it will update your devices position more accurately and get you better stability.
Be warned it will probably marginally increase AP radiation and decrease bandwidth of the wifi connection by a percent or two, however I didn't notice any difference but a huge stability increase.
I am using Beacon Period 50 at home but anything from 50-75 works for me.
Enjoy

Wifi stops working after being left for a while (still connected)

Having an issue with the Tab 2 where you go to pick it up and start browsing after it has been sitting around a while (not sure if the time matters, but it seems like after sitting for most of the day) and the wifi is still connected, but nothing works than needs data. It acts like it would if you had not internet connection. Toggling the wifi off and on will fix the issue and notificaitons and emails start pouring in.
Anyone else have this problem? I found a similar issue on the 7.7 forums but nobody reported a solution and I am not even sure if it would have worked on the Tab 2 anyways. I am thinking about making a script that toggles the wifi automatically if it detects it can't connect to the internet. But that is a little ridiculous needing to do that. It shouldn't be losing connection in the first place.
Hi Pirate
it's a bit depending on the ROM you have installed - but since Android 4 you have a quite reliable setting. The default behavior of Android devices is to deactivate the wifi connection when it goes to sleep.
Some ROMs don't recognize the disconnection and the switch/button still shows "Wifi on" although disconnected.
First step: go to settings / wifi settings, hit the menu button (top right three dots) and check the advanced settings.
Somewhat like "Keep WLAN active in standby" - set this to always.
That should solve it already under android 4.x
If this doesn't help, look into Play Store - search for "wifi keep alive". But for the SGT 2 you shouldn't need it
Greetz - Chris
It was already set to "Always" so I don't think that will help. I will look at that app to see what it does.

wifi turns off when not in use to save battery. I think it might be a default even if you have it set to always on.

The problem is that it never comes back on. Well it shows the wifi icon and the signal and everything but it just doesn't have any data connection. Any apps that use data act like wifi is off. The only way to get it to start working again is to toggle wifi or reboot. I also forgot to mention it is the stock ROM, only rooted. It got the OTA a few days ago too and it has happened since then.

It's the same effing stuff people suggest to every wifi glitch out there.
To people who think it's due to the wifi sleep policy: although I've set it to always, why would wifi not resume, after screen is turned on? It's not the wifi that gets disconnected, it's the internet (or the download speed) that stops working.
To people who suggest it's a power saving feature under low battery conditions: Sorry, I've tested it while charging and with full battery.
To people with the above two arguments: Connection to some routers works perfect with the phone. Like when I turn on the hotspot on another phone, the wifi works great. Also, wifi on the other phone from the same source (laptop used as internet access point) works well.
To people who suggest resetting the router or wifi on phone: The internet does start working again, but only for a few minutes. Even if the screen is turned on, the internet may stop working mid-download.
The actual situation is that the phone disconnects from the internet, but keeps showing a connection to wifi. Like I used connectify hotspot to create an access point, and after a few minutes, the phone moved from "connected clients" list to the "previously connected clients", even as the phone showed connected to wifi with even the download arrows blinking, but no internet (or download speed). This only happens with certain sources (of wifi). And other phones may work well with the same source.
I have tried (several times and in different orders and permutations) the following to no effect:
1. Resetting the router.
2. Resetting the wifi on laptop.
3. Resetting the wifi on phone.
4. Restarting the phone and laptop.
5. Static IPs, gateways and DNSs. (Even though the problem was not with connecting to wifi and even internet works momentarily after resetting wifi).
6. Turning off items controlling wireless network in wireless connection properties.
7. Turning off firewall.
Waiting for a savior.
I know this isn't super helpful but I had the same bug you describe on the previous version of carbon. When I updated to the latest it seems to have stopped.

Same issue. also using connectify and also tried all things you have described. If you find any solution please let me know.
I had the same problem on my Huawei Honor. You need to set static IP in wifi settings (when connecting to AP, press "show advanced settings").
Mine settings were:
IP adress: 192.168.1.75 (make sure other devices are not connected with this IP)
Gateway: 192.168.1.254 (it could be different. Use the same as you're using to connect to your router)
Network prefix length: 24
DNS 1: 8.8.8.8
DNS 2: 4.4.4.4
No option for static IP in connectify

1. I have had the exact same issue for (atleast) the past 2 years. Have survived by repeatedly turning wifi on and off.
2. I too use connectify. This issue doesnt seem to happen on every wifi connection (just like your case). Even more specifically, it seems to happen ONLY when I connect my phone to the hotspot created via my laptop (connectify).
3. Even when the internet is actually working, some apps do not seem to recognise that(take some time to realize it is working), while others are able to connect instantly. Specifially, whatsapp is unable to send/receive messages for about 1-2 mins, after which I receive a whole bunch of messages at once.
This does not seem to be an issue due to connectify as well. I have tried creating a hotspot from my laptop without using connectify as well, but unfortunately, nothing changed. Further, this does not happen when my phone connects to a hotspot created via connectify by some other pc. The wifi and internet work perfectly fine when connected to a hotspot created via my friends computer.
Further, this problem happens only when a mobile connects to the hotspot. Doesn't occur when another laptop/PC connects (not sure about tablets).
I have looked into every nook and cranny on the internet, explored every forum for any working solution, but have been unsuccessful. In fact, this is the first place where I saw the exact same problem as mine, and was wondering if you have found any solution to it .

I'm having the exact same prob on my ZTE Grand x V 970
It started when i had kitkat and i couldnt even "fix it" restarting the wifi, i had to reset the phone in order to have my wifi work for like 2-5 mins and then stops recieving data, tried to reconnect and stays on turning on wifi.. Now i changed to the stock Rom and the problem is still there but at least now i can "fix it" restarting the wifi connection until certain point.
Issue sharing internet with Connectify from PC
Go to:
Control Panel\Network and Internet\Network and Sharing Center
On the left column, click on CHANGE ADAPTER SETTINGS.
You should be in: Control Panel\Network and Internet\Network Connections by now.
Then click on: Microsoft Virtual Miniport Adapter and click on Properties, then click on the 'Configure' button in the 'Networking' tab. From this window, go to the 'Power Management' tab and uncheck 'Allow the computer to turn off this device to save power'.
This works for me. Try this out
If this doesn't work further, you can try out mHotspot for the same purpose.
I've had the same issue, with the wifi saying it's connected even though it isn't.
This thread is 4 years old and this issue still hasn't been fixed. What a shame.
Same issue here on OnePlus 3 even after factory reset.
I have this same problem after the security patch Mid March to Jan 1, 2019. The WIFI doesn't show in the top status bar, but toggling wifi off/on fixes it till the next overnight. I did make one change to my wireless about that same time and that was moving the min connect speed from 6Mbps to 12Mbps to help with bandwidth issues being cause by devices using low speeds and having several SSID broadcast. My S7 and Tab A both work fine - so I think it was something in the security patch.

[Q] Galaxy Note Pro 12.2 WiFi Connection Problem

Hi All, I've bought one of these beauty's and am well pleased with it. However I have come across a small but annoying problem that I hope someone can help me out with.
At initial set up I connect to my home network. This works absolutely fine. When I set the tablet to connect to my tethering hotspot on my S4 that is when problems occur. It connects initially but then shows disabled. The same now happens with the home network. The home network is via a HH5 which has both 2.4GHz & 5GHz. enabled. Telling the device to forget each of the AP's and reconnecting them does not work. Other devices (W7 PC's, the telly & another S4 ) can connect to my tethering hotspot without any problem.
My Sitecom Router did this, I had to disable OPS on it and do a hard reboot on the router. Give that a try.
I have the same problem...continue disconnection and reconnection...help me!!!
Try switching the channel. Use this APP to find the best one: https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer
For me, adding the Note to the static DHCP List in my router settings (trendnet TEW-652 BRP) seemed to do the trick. Some people also recommend changing 802.11 mode to single (g or n) as opposed to mixed (g and n), and changing IP to static in the Note Wi-Fi settings.
... Note Pro 12.2 (900) ...

I had to change the broadcast channel on my hotspot to 2.4GHz to get the Galaxy Note Pro 12.2 to see the WiFi network.
Mine's doing same thing. Turn off DHCP in wifi settings of 12.2 Pro and use a Static IP way the hell up there on the range so one of your dynamic devices doesn't grab it.
This tablet is such a piece of crap. Been trying to sell it forever. Definitely the worst display on any of the newest-generation Samsung devices. Plus it has these retarded problems with completely rudimentary technologies.

[Q] WIfi disconnection on certain networks

Hi everybody!
I'm using the latest build of CM11S (KTU84P), When i'm connected to my home network (using a Dlink 6740H1 router) the connection to the wireless network will stop after a few minutes.
The wireless icon will become orange and there will be no data transfer what so ever. When I'm connected to other wireless networks the phone works fine and does not disconnects.
The "Keep Wi-Fi on during sleep" option is checked and the "Avoid poor connections" is not checked, further more I've tried flashing franko kernel but it didn't change anything.
Other phones in the house (HTC one X) does not seem to suffer from the same problem, did anyone ran into this issue before?
Thank a lot!

i have a similar problem with the latest rom.. KTU84Q (38R).. my wifi wont connect to my home AP.. never had this issue pre 38R.
Did you find a solution to this problem?
I have the same problem..
I am also having this problem.
I'm having the same issue with our router at work. Have you tried setting up a static IP for your home network?
problem with wifi: i connect to a network (password) and everything is ok until i go out of coverage. when i go back in area, the phone scans/finds the saved network but does not connect auto, i have to turn off/on wifi and then it connects.
on all networks, dosen't matter the router model or type of network (password or free, static/dinamic IP)
Try deleting all the saved Ap and re-add them. Seems it worked for me, now it connects to Wi-Fi. I had many saved from trips (hotels, pubs Wi-Fi with password and many free)

Help, can't connect to Wi-Fi!

I just bought a Samsung 10.1 Note 2014 tablet (Android 4.1.2) off a private seller. In trying to connect to wi-fi, I find I can't, but I have no problem connecting with my Galaxy Tab 4. At first I kept getting "authentication error". Then I switched from WPA-PS2 to WEP security, and then it worked. one time Then when i changed it again to try out WPA-PS1, it wouldn't work at all on wifi, even switching back to WEP! So it appears to have nothing to do with the security type.
I've tried deleting and recreating the wifi network info, Hard Reset, Factory Reset, changing the wireless channel, using the default WEP password on the router, resetting the router, changing the wifi channels/power/modes (default is 802.11 b/g), connecting with WiFi Analyzer app,
Ever since changing the channel, and returning it back to default, it now only gives me this error: "Network Disabled, Poor Connection. Even though it lists the signal as "Very Strong" (I'm only inches from the router!). Anyone have a clue as to what's going on here? Is this is some sort of defect with the wifi card on these Note tablets, or is it solvable via software?
