    Default WiFi Issues in Note 3

    I just recently bought a Note 3 , and i am starting to experience WiFi issues
    I have 2 routers both which are having a problem with my note 3

    1st: Cisco E900
    Problem: The note 3 connects but internet does not work , it says DNS error but it is working on every other device

    2nd : Some random router
    Problem: Whenever i try to connect , it connects but it keeps on saying Obtaining Ip address after 5 minutes it gives an error saying that my internet connection is too slow to connect

    I fixed my problem. I am using connectify in my laptop. But my note 3 shows unstable wifi connection. Then I updated my laptop wifi driver. Then in note 3 I off wifi power saving mode by dialing *#0011#. Then I unchecked all notifications in the wifi advanced menu. That's it.

    When you go to the 0011 menu uncheck power saving mode

    I am having very similar problems with my Note 3 after updating to Android 4.4.2
    I can not connect to a secure wifi with password, the signal is strong however the device keeps trying to connect and eventually "Authentication error Occurred" appears
    I can connect through web based wifi in pubs and restaurants but not through this secure connection.
    It appears that the password typed into my device is not recognised by the wifi (I am using the correct password)
    I have tried the *#0011# to no avail

    Thumbs up Re: WiFi Issues in Note 3

    +1 for Nayan's solution, the main issue at hand definitely seems to be tied to the "Power Saving Mode" on the WiFi. I've tried a ton of things suggested by service techs and community members alike and this is the first idea that's done anything to help so far. If you look around, a number of forums are flooded with Note 3 users having this same issue regardless of service provider or router manufacturer and most threads still don't contain a helpful answer, so hopefully this one will bubble up to the developers for Google/Samsung to help isolate the source of the problem. Thanks for posting!

    It is connectify software. It turns my laptop to wifi hotspot.

    Always use update wifi driver in PC and update your router software. When using wifi you should off mobile data network. Also off wifi power save mode by dailing *#0011# then press menu (left button) then see wifi option. That's it.

    I was having a similar problem so I did what you did and dialed *#0011# and turned off power saving. It worked! I also noticed that for my wifi network it said connected to 802.11n. I have a 802.11ac network, doesn't the note support 802.11ac? Why isn't it connected to that?

    Note 3 supports Wi-Fi 802.11 a/b/g/n/ac, dual-band, DLNA, Wi-Fi Direct, Wi-Fi hotspot. May be something wrong.

    Had a similar problem with wifi working fine in Safe MOde, but shutting off within 30 secs in regular mode. Tracked the problem back to a recent update from McAfee Mobile Security which added Web Security features. For whatever reason, it flagged by WPA secure Wifi as "Unsecure" and kept shutting it down. By opening Web security in the App and turning off Wifi Security my problem was solved. For the record, it did this at TWO (2) separate (but both COMCAST) wifi locations. I find it hard to believe they were both compromised or being sniffed.

    Thank you soooooo much for your solution! My Wi-Fi worked fine up until 3 weeks ago. Wi-Fi just stopped working for No reason. I had to go to best buy and get a Samsung Rep to flash my phone with the 4.4.4 update. Samsung couldn't figure out the issue with my Wi-Fi either. Checked my wifi with Clear as well. I had tried everything except a hard reset and replacing my phone. I finally came upon your post and voila! Disabled wifi protection on mcafee and my wifi works! Thank you sooo much again!
