So me and others have many devices on our home wifi network that doesn't broadcast its SSID. Playstation 3's, iPads, iPhones, 3DSs, Galaxy Nexus, and even an HTC One.. none of them have any problems connecting to our wifi network even though it doesn't broadcast its SSID.
My new Samsung Galaxy S4? It's constantly forgetting both the home and work wifi network, and neither one broadcast their SSID. I'm constantly having to type in the SSID and password manually every 2-3 days and it's frustrating beyond belief. (I believe it may be releated to when the phone is reset because it's not EVERY day... but still often enough to be annoying as hell.) Why does every freaking device except a Samsung Galaxy S4 capable of dealing with a wifi that doesn't broadcast its SSID?
I connect to a wifi network with a hidden SSID every day at work. I have never had the S4 forget the network. It could be a problem specific to the type of router you have.
I don't think so. The routers I have at home and work are completely different brands and types and it occurs with both. And all of the other devices I listed had no problems with either. I suspect it's something with the Samsung / T-mobile wifi functionality as other Android devices don't have any problems.
I agree that out its likely a problem with the S4, not the router, but it still could explain why you have this problem and others don't. If it is a software problem, you may have to wait for T-Mobile to push out an update. Other carriers have, but who knows whether it fixes any wifi problems.
What kind of security do you have setup on it?
I use 4 different routers all that don't broadcast and I can replicate the problem.
I have WPA2 set up on both networks... another issue I've been having is that the phone has disconnected purposely from the wifi networks reporting "slow connection" a few times. I'm not sure if that's related, but I don't think it is. After a certain point, the S4 doesn't even seem to try connecting and stops listing the SSIDs in the list of "known networks".
That definitely might be it.
If there is slow to no responses from the connected network it will disconnect and avoid.
Has any other device noticed slow downs on the connection?
I would also try at a open connection, say at McDonald's, and if it is still happening that would definitely mean something is off with the phone.
I can understand (maybe) why it would disconnect temporarily, but what I don't get is why it would completely forget it. If this is what it needs to do to support Wifi calling and texting, I'd rather just disable that feature. But in any case, any network is going to have a crappy connection if you go on the edge of the range of Wifi, and the fact that it may be disabling, and in this case even completely removing the credentials for, such networks is just ridiculous.
My phone just started doing this only in my house. My SSID is broadcasted. If I turn off my WIFI, I must reenter the information over again because it seems to have forgotten the password. I have had the phone for about a month, and only started this week. highly frustrating! I turn off teh services I don't use throughout the day and now I must be forced to leave the WIFI on when I am not in a known area.
I've seen this in my S4, and found a fix. Go to your Wi-Fi settings, too the page showing available connections, and press the menu button, and select Advanced. Turn off the option for "Check for Internet service."
I found that as I walked out of range of my home or work router, the phone was detecting the connection didn't work any longer - but instead of just figuring out i was out of range, it was marking it internally as a bad connection! That kept it from automatically reconnecting the next time i was in range, and forced me to re-enter the password when I manually tried to connect. I turned off that setting, and haven't had a lost access point yet.
