Do you get the color change as described in this thread? http://forum.xda-developers.com/showthread.php?t=1261253

Mine does this
My bionic also stays connected to the mobile network when wifi is on and sometimes it will pull from the network instead of switching to wifi. the radio is all messed up on my bionic.

Well is not a mess I mean when I am connected to wifi my phone use wifi internet instead the mobile data but I guess with wifi n mobile data use more battery I guess I don't know the revolution is like bionic the same happens

I see this on mine as well. I know some people have indicated that it is not really connected to 3G, here is what I'm seeing:
When Wifi is turned on, the 3G (or 4G if lte is enabeld) sometimes stays on. Sometimes it changes to white (indicating that it may still be connected, but not syncing to google through that connection), sometimes it stays blue, and once in while it actually goes away, but not often.
Some other threads seem to indicate that this is just a display bug. However, if I analyze my battery stats, I think the connection is actually staying on. Here is what happens:
* With just a plain 3g/4G connection and no wi-fi, if I look at the battery stats for Cell Standby, the "time on" increases as expected. If there was a period when the cell signal was dropped, I will also see the percentage ot time without a signal.
* When I turn on Wifi and the 3G icon stays on, if I look at the battery stats, the Cell Standby's time on continues to increase, but not the "percentage of time without a signal" also increases. This seems to indicate that the cell signal is staying on, but it knows it is not connected and is searching for a signal. I'm not sure if this is actually eating up more battery like when you really don't have a signal and it is searching, but it is being reporting that way at least.
* If I install a widget to disable 3G/4G while on wifi, the icons go away, but I still see the same thing happening in the battery stats. This could indicate that it is still connected, or it could invalidate what I'm seeing altogether, not sure.
In any event, I'm not sure what the real story is here, I never had the icons stay on with previous devices (Droid X and X2), so I never investigated the battery stats. However, I see alot of people talking about their Cell Standby taking up a lot of battery, I wonder if this plays in to it.

yeah I don't think it's really on either. I verify this by using speed test. I know my speed at home and lte is faster. lol

When I use juice defender I disable mobile data when connected to a wifi SI icon disappear this happen with the revolution and bionic I don't see on tbolt nor charge

My 4g icon stays on while connected to wifi and stays blue. But according to speedtest the speeds reflect connection to wifi.

Mine is doing the same, but its still draining the battery like CRAZY when browsing on supposed wifi... Definitely a bug.

Mine is the same way but I can't use anything on my network like google tv remote or printershare it says it can't see anything on the network. Tried other phones and they work

It should prefer wifi over 3G/4G. I keep this page bookmarked on my Droid that shows IP and ISP name to test it.

I have been on wifi all night. 3g lights on. However, my data useage for the month have not changed. I am confident that 3g is not being called upon

My experience is similar.

Mobile Hotspot issues - incredibly slow??

Anyone having this issue? My hotspot is brutally slow. Most of the pages don't even load and when I can get a speed test to run, its below 1mb. The phones speed is standard LTE speeds of 20mb around this area.
Is there even anything Verizon can do about this or is the phone messed up?
Thanks.

Is it the offiical Big Red Hotspot ? or are you rooted?

I get 26mbps download on the 4g through the phone, and 12mbps on the laptop when using hotspot. Everything seems to be working as intended, could be a problem with defects.

Legit hot spot.

i have the legit wifi hotspot too. the speeds are all over the place. i have a problem with connectivity. i can only last a few minutes then it disconnects and sometimes reconnts or i have to reconnect it. sometimes my phone reboots when turning off the wifi hotspot. anyone else have similar issues? i do have to say that the usb tethering option has been flawless and very fast.

[Q] Unstable WiFi Connection.

One issue i've noticed about my Note 3 is that where i would normally have great wifi connection with my old S3 (in my own living room) my note 3 would give me a notification saying the "Wi-FI connection is unstable". Even in my room sometimes i would have a perfect WiFi connection and other times i have a wifi connection but it is too "unstable" to use. On top of that i've noticed my internet speed on my Note 3 is significantly slower than my S3, and i know it isn't my wifi connection because my laptop runs the same speed as it always has. I was wonder if anyone could help me out here. Is it a hardware or software problem?
Any help is appreciated.
Thanks!

I get this every once in a while when I am at the fringe of the WiFi range or where there are an excessive amount of WiFi overlapping. The WiFi strength on this is much better than any other phone I have had as I can actually go into certain areas of work now and still connect. These areas are pretty much a large metal lined box so wasn't expecting to connect as my note 2 doesn't, an iPhone 5 & 5s will not connect in there either.
I just turned off the automatic switching between WiFi and mobile and no longer get the message.

I tried turning off that setting and this problem still occurs. Is that a hardware or software problem? Have i maybe received a defective Note 3?

wipe your cache partition. you don't lose any data or important info or apps. some reported this helped them. http://support.t-mobile.com/docs/DOC-9049#cache_partition

Data and Wifi completely drop, have to do airplane mode to turn it back on

I don't know why, but this is a consistent problem and it's getting annoying. I will only have bars, but no wifi or internet connection. This just randomly happens and I don't know what triggers it.
I have to turn airplane mode on and off to fix the problem. Is there something that is causing this?

This doesn't really help.
What happens is data and wifi disappear and if I hit wifi it won't turn on. I have to turn airplane mode on and off and it starts working again.

I have had the same thing happen,but only once or twice,I chalked it up to my home WiFi threw Comcast ,I've been having major problems with my Comcast modem dropping WiFi or to slow of a connection,think I have to replace the modem just been to lazy,but I have the smart network switch on in my phones wifi settings so I thought maybe from the signals switching so much it froze or something,but yea it did same thing I had no lte or 4G next to my carrier signal,the wifi was not allowing me to turn it on,or scan for networks,wasn't even showing any so I did the same thing hit the airplane toggle and it came back.

Sorry i have no others solution for it.

I just posted a thread about the EXACT SAME issue. It only seems to happen overnight, but when I wake up in the morning my wifi has been turned off and my 4G LTE isn't working. When I try and toggle wifi back on it gets stuck and never reconnects/turns on. My solution has been to restart the phone.
I'm thinking since this seems like a rare problem, that this is a device-specific issue. I'm going to try and exchange mine this weekend due to this problem and hopefully get a properly functioning GS5 instead.

Have the same issue (made a post about it already in this forum). Usually happens when there is a large fluctuation in signal. Grocery store where I get no service results in no service when I leave the store as well. Have to cycle airplane mode like you described.
WiFi hasn't done it yet.
Another forum member suggested it may happen if using an older style SIM, which I am (from my S3). I haven't been up to change it yet. What SIM are you guys using?
http://forum.xda-developers.com/showthread.php?t=2744472

I typically have this happen when I'm at home at night, while my phone is plugged in and on wifi. Just disconnects at some point overnight.
I'm using a brand new SIM provided by AT&T when I upgraded in store.
Very strange issue and is random. For instance, it didn't happen overnight last night.

My S5 just started dropping data randomly and causing my battery to drain with almost no usage... I tested using Skype in a good 4G LTE area and will start out with 4 bars and the 4G LTE icon but as soon as I try to initialize a test video call over Skype the signal immediately drops to either no bars at 4G or it will go straight to E!? I haven't had this issue in a long time and it just suddenly started. At first I figured maybe they lost a tower but now this is going on almost a full week. I've got unlimited Data so I know that's not the issue, it has a brand new SIM... I'm going to AT&T and see if they have an answer or if they'll swap it out. Annoying!
Also annoying that sending a simple text will fail... ugh no root and now no data! :what::banghead:

I've had this happen several times, but only at my work. Reception is poor at my office, and the company WiFi requires browser-based login each hour, which I switch to many times a day.
The phone basically stops using all radios EXCEPT bluetooth, showing a circle with a line through it. I've been rebooting the phone to restore connectivity, but will try toggling airplane mode next time. I haven't noted any strange battery drain.
I haven't seen this issue when wifi is disabled.
I didn't notice it locked up a few days ago and drove home where cell reception is very good. The phone didn't recover until I rebooted it.
I have a brand new SIM from ATT and use a Gear 2 (which is greatness, btw)
I've done the following:
1. disabled the damn ATT hotspot app
2. Disabled/enabled the Wifi connection check setting
3. Did a full factory reset
This is getting close to a deal breaker for me.

As an update...
I have this issue basically every work day with the aforementioned environmental variables
Today, I:
Disabled Bluetooth (left the gear at home)
Disabled wireless
Switched radio to 'LTE/GSM/CDMA Auto' with instructions in this thread
The radios haven't locked up and reception is much better.
I'll try leaving WiFi/BT on and use my Gear again next week.

For anyone who is still interested, changing the modem setting seems to have resolved the problem for me. It also improved connectivity in weak areas a good deal.
Unfortunately you must enter the key sequence to toggle the radio each time the phone is restarted.

lazy wifi?

so my Wi-Fi gets 16 Mbps+ and my lte gets only like 1 at home however things like Facebook update images and videos much slower on Wi-Fi. and sometimes images don't load at all on Wi-Fi but on lte everything works as expected. no packet loss and better ping on Wi-Fi... so I don't understand what's going on
