Bought my Galaxy yesterday and it works fine but on one point. Yesterday I was able to find the home network of my friend in his house. I could connect to the internet with that as well as through 3g. But later at my place it does not work with any home network. When I try Settings, Wireless and network, Wi-Fi settings and Wi-Fi, the phone turns on Wi-Fi and scans for some seconds and the leaves a message that says "Unable to scan networks".
Maybe I have switched on or off something accidentally as I am a new user on this phone? Anyone for help?
turn off the phone
then turn it back on
in another words, reboot your phone, seems like it got stuck in some WiFi bug
It does not seem to help. I even took out the battery. Still unable to to scan
you can try this
*2767*3855# WARNING! FACTORY DATA WIPE AND RESET as soon as you enter the last # use it only if you want to clean wipe your phone

I really don't want that as long as I also cannot backup the video in it. Have not got the Kies program to recognize the phone yet.
Maybe there is another way to set the scan possibility?

you don't need kies
see the last secret code?
It defaults to User space. I do not yet have any extra Micro SD card. Is it that what means with User space?
Tried that last command and do have at least one file of each in the folders, but the phone answers for each of them that the files are not ready? What else is there to be done?
Had same problem, tried factory reset... didn't solve it. any ideas? it can't get an ip address and it used to work
probably the next best thing is to use Odin to reflash the modem file to the phone
or a full flash to the latest firmware
Same problem appeared on my SGS. Boy this sucks. The wifi became "hard" to connect sometimes. Or I could connect but had no internet access. Then I disconnect and connect several times to have net access.
One hour ago the wifi died. I turn it on it says "Unable to search for networks" and shuts itself off.
WTF. I have to reflash!!!! Not good. Also I don't know what caused this. I'm on JM2 with One Click Lag fix 2.1
one thing is for sure, the STOCK rom has no problem with that
so it is either a Router thing, or a firmware specific problem

JM2 isn't a final release firmware. Realistically, if you want everything (well, other than GPS) to "just work", stick to official firmware.
Well, I for one, have only the the official firmware and it is the latest one what I have learned. Still the phone behaves as in my original post after just a couple of hours. Is this and other peoples beautiful Samsung Galaxy model not tested enough by Samsung? Has anyone more information than we have?

I agree thats Help me. or you can try upload update.zip (file to make root) on your device and flash that can help too.
Hi all! Thank you for your inputs to my problem. I have now got it working. For those who are interested how, I can tell you that I only did a simple Factory Reset command.
problem solved!
I had the same problem.
I was trying to configure a invisible ssid and by distraction I created a normal WPA 2 network, ending up with two networks with the same ssid (when I was turning off the wifi, it wouldn't go off at the first try, weird, )
Solution:
Edit the "/data/wifi/bcm_supp.conf" (with root permission) and eliminate the duplicated network, problem solved! At least in my case (no need for factory reset )

My device was working perfectly fine today until suddenly it stopped being able to find any Wifi networks of any kind. It doesn't say there's any issue, it still scans, but it doesn't find anything at all. I'm searching on my uni campus, so I know that in any one place there's about 12 connections, and my phone has no issue finding them.
I've done a factory restore, but it didn't seem to help in any way. Is there anything anyone can suggest?
Edit:
Bluetooth still works, but I'm not sure if they're on the same chip in the 7.7
I just had similar issue with my home wifi,
Other devices works fine, and there's no problem connecting to other wifis..
I tried deleting the dhcp list via root explorer, tried wifi fix, rebooting couple of times but none worked..
Then i tried to reboot the router and surprisingly it works!
It's probably because the router is giving a static address that's different with the previously recorded in your tab.. But i'm not sure..
So if your tab still works in other wifis then chances are the router needs to be restarted..
No WiFi networks show up at -all-. I've got a completely blank list, even though there's plenty of connections available.
Hello,
I've already searched the forum for an answer but I've been unable to find any solution.
I have a GT-i9505 Galaxy S4 with Omega ROM. I though flashing a new rom will help me but it's the same.
Everytime I walk away from my router, it automatically sets the wifi as "Network disabled because internet connection is slow" and won't connect again. I have to manually click connect to force it to connect it. Also, when I'm in my University, it keeps disconnecting for the same.
How can I avoid this and force it to stay connected? Do I need to flash some custom modem or something?
Thanks
The answer!

TRY THESE STEPS
1) Settings => Connections and tap Wi-Fi. Then tap Menu and make sure Keep Wi-Fi on during sleep is set to Always.
2) Turn off Wi-Fi power save mode on your S4. Type *#0011# on the phone dialer, then Menu => Wi-Fi and turn Wi-Fi power save mode to Off. (WORKED FOR ME)
3) Or change your router settings to 802.11 model
Galaxy S4 wifi non-connection/drop out NEW FIX
Had a problem for ages with my S4 not connecting to wifi and therefore no internet, no updates etc. My router is a Netcomm NB6Plus4Wn but this may work with most routers.
It would constantly go through the authentication, secured/saved cycle but rarely actually got an ip address.
After trial and error I found this worked straight away and it is a very easy fix.
Go to your router settings page, then wireless settings, look for Primary Channel setting.
There may be a (Lower/Upper selection) - tick the LOWER radio button and apply changes. Let router reboot.
Note I also use WPA/TKIP settings for security.
Test your S4.
Mine was set to Upper Primary Channel previously and as soon as I changed that setting to Lower Channel wifi and internet worked immediately.
I hope this helps some people with this common problem as I know how frustrating it can be.
Cheers
wifi verification problem
galaxy s4 GT-I9500 running pac-man rom. just started getting verification problem connecting to my linksys router one foot from my phone.
did the following on my phone: settings, Wi-Fi, settings, wps pin entry, msg reads " enter pin xxxxxxxxxx on your Wi-Fi router." where xxxxxxxxx is a number.
logged on to my router, clicked on Wi-Fi tab, under Wi-Fi protected setup, it asked me to enter the wps pin number from my phone. I did and after a minute or so, it indicated success and now my phone connects to Wi-Fi
weird. my phone connected for months without this procedure but just started failing today. thanks to the one who suggested checking the router setup.

I recently ran into the same problem and my wi-fi button wouldn't come on no matter what I did. Finally, I took the phone to Best buy as the now have a Samsung store there and the guy reflashed my phone with the 4.3 update free of charge and it worked. When I got home I rooted over my phone and now my wifi works fine. Hope this helps.

p.s the phone does not work on a custom rom yet since i encoutered this problem and want to fix it first.
My S5 wont even recognize the fact that my home WiFi is close by, it used to do so but today it just wont find it at all. Everything els works, Computer, tablet other phones but my S5 simply wont find the WiFi to save its life.
Anyone have any idea as to what this might be, I've tried the following:
Restart everything
"forget" the WiFi settings
add my WiFi manually
Changed every setting possible
I dont seem to be able to get it to work, period.
Help? Anyone?
Just want to clarify that my phone do find other WiFi's it's just this one network at home that it wont find. I didn't have any problem with this WiFi up until today.
Make sure your network selection mode is set to auto instead of manually.
Hi everyone,
Since Friday my phone just stopped connecting to Wi-Fi networks. When it tries to connect it says "Network access denied". Mobile data and everything else work fine. I can technically connect if I literally put the phone on top of my router but even then it is unusable. Take two steps away from it and the connection drops. I spent the whole weekend and yesterday looking for a solution. I tried almost everything including resetting the phone, updating the phone from the current version to the B524 beta and back (rollback wiped my phone but I don't mind), the airplane mode trick and countless router rebootings. I really hope it's not a hardware issue, I've only had the phone for a couple of months... To make matters worse I ran out of data allowance and have to wait until next month for it to come back.
So yeah, kind of an annoying situation. Anyone know what is happening?
Thanks.
Have you already tried to connect to other wifi network, problem could also be in your router ...

I did, yes. I've tried to connect to mine, my brother's and some unsecured one that was near me.
if you are rooted then i suggest full wipe in twrp , download new rom and see if it works again , if not it must be the phone who has hardware problem.... and repair shop is needed
I have the same problem, my P8 Lite Wi-Fi just stopped working, tried several different Routers that used to work but just get Network Access Denied. Think this must be a software problem.
Hey !!! anyone get this solution will please help me i am facing same problem "Network access denied"
tried also Install New Rom but nothing will happen ... ???
Hey.
Im having same problem...visually everything works (not greyd out), but when scanning, scans for a second and then thats it. Tried wifi direct, doesnt work.
Also bluetooth doesnt work (same as wifi...cant find nothing).
Tried all those "tricks" what i could find on google, tried all rom builds, rooted-unrooted...nothing works so far.
