Galaxy S5 WiFi keeps dropping and reconnecting

Galaxy S5 WiFi keeps dropping and reconnecting

I have a very strong WiFi signal at home. I connect easily enough, but every few seconds the WiFi signal gets dropped and it reconnects. It's extremely admitting, especially because the connecting message keeps popping up and interrupts typing. Any ideas?

Re: Galaxy S5 WiFi keeps dropping and reconnecting

I have 5.1.1 on my S5, and wifi keeps disconnecting, scanning, and reconnecting to my landlord's new 2.4 Ghz wifi. My laptop has no problems. Had no problems with previous wifi.

Re: Galaxy S5 WiFi keeps dropping and reconnecting

Three days ago an AT&T update came through and I OK-d the installation. I have a Panasonic Home Network security app on the GalaxyS5 and it worked like a charm before the update. Now, it diconnects from the Home Network hub and I cannot reconnect unless I clear the cache restart and do all these conlicate steps. Now, my home security system is useless since I cannot control anything through my phone or look at the property when I am away.

Yes, I unchecked smart network switch and went through on everythig recommended on these three pages. Is there an AT&T patch to resolve the issue?

As I said, it did work perfectly before the AT&T update so I assume it is not a Samsung issue.

Re: Galaxy S5 WiFi keeps dropping and reconnecting

Galaxy s5 same problem. I was wondering why my data was 2 gb's over the limit. I couldn't figure it out, until this update for ATT came up today and wouldnt download because wifi wasn't connected. It looks like it's connected, but it isn't.

I have tried everything listed to correct it. Come on ATT, tell us the real fix.

Do I use mobile network for the new update, which eats a lot of data, but then the problem will be fixed?

Re: Galaxy S5 WiFi keeps dropping and reconnecting

@intergalaxy There has been an ongoing connectivity issue with the S5, which began with the 4.4.4 update.

 

In the solution posted by ATTMobilityCare, it was noted that Samsung and AT&T were working together to resolve the issue; however, the issue has never been resolved.  The only workaround that is known to prevent the phone's unintended usage of data is to uncheck the "Smart network switch" feature.  This does not prevent the constant scanning; however, it does prevent the phone from constantly and unnecessarily switching over to data while a perfectly good WiFi connection remains available.  Also, when "Smart network switch" is not enabled, connectivity is improved, not necessarily fixed, but it is improved.

Re: Galaxy S5 WiFi keeps dropping and reconnecting

So this implies that I have no wifi.
The solutions aren't working for me. I do see it's been happening since
last year. What is a the fix time frame? Can we back up the update to the
one before the problematic occurred?


Thanks for your help.

Re: Galaxy S5 WiFi keeps dropping and reconnecting

With "Smart network switch" unchecked, I usually have a good WiFi connection, but not always.  At least that keeps the phone from gobbling up data. Reverting back to 4.4.2 is not supported.  To the best of my knowledge, there is no fix in the offing and, given the phone's age, I have no reason to expect that status to change.   

 

Sometimes, even though everything indicates that I have a strong connection, the phone just will not connect to the internet.  This happens even when the phone is only inches away from my laptop that easily connects to the same WiFi network as do other wireless devices in my home.  I have a tablet, an ereader, an Amazon Echo and a Dot, none of which have a problem connecting to my WiFi network. This is definitely a Samsung issue. 

 

I have noted a number of complaints regarding Samsung connectivity issues, complaints that are not exclusive to the S5.  Due to this issue, and others as well, such as but not limited to lagging updates, a problem that has been highly exacerbated by AT&T's delays in releasing updates, I have decided that the S5 will be my last Samsung phone.  In addition, I have no intention of purchasing another carrier branded phone.

No, uninstalling the Marshmallow update is not an option.

Re: Galaxy S5 WiFi keeps dropping and reconnecting

My Samsung just started dropping the wi-fi today.  I am not getting any help on a fix.  I am beyond frustration.  One minute it works and the next minute it doesn't :-(

Re: Galaxy S5 WiFi keeps dropping and reconnecting

I have the exact same problem with my S5. I realized it had to do with my phone when several friends came over to the house and ALL of them had no problems with my wi-fi connection. So, I figured that my phone updates might be the cause, and sure enough, so checked my "SECURITY AND PROTECTION" UPDATE!!!  Just uninstalled it back to factory settings and No more problem at all. Back to normal.

Re: Galaxy S5 WiFi keeps dropping and reconnecting

Go to your setting/application manager/.. search for the installed security
or protection app. It could be named anything. Mine said "security and
protection". Select this app it should show info of the last update. My
phone has two ways to shut it off. Either uninstall or force stop. I chose
uninstall. When I selected uninstall it brought up a choice and I went back
to factory install which came when I purchased the phone. I selected and
volahh!!. I use android o.s. ver 6.0.01. Hope you enjoy. John
