[Completed] Very slow internet when connected to wifis - XDA Assist

My phone is samsung galaxy ace 3. It connects to wifi networks with no problem but i barely have internet. It is not the problem of wifi networks since they work fine with all other devices. I've been to a few private phone fixers and they mostly said it is hardware problem.

Specific wifi problem... can't connect to school wifi

My note is functioning normally! I dont have any problems with connecting to wifi at home, friends' places and even public wifi at like tim hortons etc.
BUT it doesn't connect well to the wifi at my university... and it definitely isn't the problem with the wifi signal or anything as my phone (galaxy note) connects fine as well as my laptop etc... I am not sure how to solve this problem... let alone figuring out what exactly is wrong...
In order to sign into the school's wifi, one will need to put it an id and password.. its a WPA wireless network.
To be more precise, my note sometimes will be connected to the school wifi fine without any disconnection but very frequently (at least 75% of the time I open up my tablet at school) it will not be able to connect or sometimes disconnect stochastically. I will have to try turning my wifi on and off a few times and if that doesn't solve the problem (which is the case for most of the time) I try restarting my tablet.... most of the time if my tablet decides it doesn't want to connect, nothing seems to work! I will just have to try and connect to the wifi some other time.
Any suggestions?
Thanks!

Bumping with hopes of a reply.
More info: usually the error is authentication error or wrong password or just doesn't connect.... all the info inputted is correct

Your school Wi-Fi just sucks, it's unstable. Or you have on your note an app that uses an restricted protocol. As an example, a router can be set to drop any yahoo related connection. But most likely just an incompatibility between your note and the router.

Could it be a region area cause wifi networks of that size have a lot of different routers all over the place working together and each router can be programed individually to do certain things like drop as the previous post said yahoo related protocol for example so does it work in some areas and not others
I'm having this exact same problem at my school. The wifi will intermittent reconnect, and sometimes won't automatically connect when I enter the building, regardless of the signal strength. It will say "authentication error" sometimes when it doesn't auto connect. Often it will also reprompt for the WPA key even though the saved one is correct.
Wifi works flawlessly at home, work, and friend's houses, but has issues with the school's.

Had similar issues at my school, its not your tablet its the wifi generally the signal strength is bad and that's y i struggles to connects but works sometimes, i realised it was router and signal when even iphones had problems
I made a topic about this a while back. The success of connecting seems to depend on the proximity to the wireless base station and amount of other wifi devices. Even in the worst environments, if I go into settings and disable/enable wifi multiple times it will eventually connect. I get the authentication error fairly often and just ignore it, disabling/enabling until it connects successfully.
I think Samsung WiFi drivers just suck happens to me all the time if there ever a login to connect

Ask the IT administrator if there are any limitations. Show him that you can't use the Wi-Fi with your device, maybe he will be able to help you.

Hi everyone! I really need to help me with my wifi network problems.

I have a Samsung galaxy s3. In our company has wifi signal very good but IT admin had configured with WEP mode so laptops can easy connect with wifi network, but there is any mobiles can connect with wifi network. But anyone who has HtC can connect with wifi. I have a friend, he has a HtC One, when he connect with network I see in configuration has Index selection, he chose number 3 and he can connect. But in my configuration wifi doesn't has Index selection so i can't connect with network. Who can help me. Please! I don't know why?

[Completed] Mobile data not working.

The mobile data doesn't work in certaing places of my city. Unfortunely .. like my home. I have Wi-Fi so no problem, but it's really annoying. I have Android 5.1, Ulefone Paris.
When I turn data on nothing happens. When it's working there is 3G or 4G next to the signal icon in status bar. But it doesn't show anything. Idk if it's related to the cell towers but if anyone heard of this before please let me know. Thanks
*bump* any?

[Completed] Need some help

I know Verizon just came out with the update to marshmallow for their Galaxy Note 5. I am wondering if anybody else is having intermittent Wi-Fi issues or having significant battery drains on their verizon galaxy note 5 after doing the update to marshmallow. The problem that I am having is that I will have the phone connected to a Wi-Fi network and it will sometimes work and other times it will show up on a web page unable to view page due to no network connectivity. It will happen on any wireless network not just my home wireless network. I have also noticed a significant battery drain after the doing marshmallow update from Verizon. If anybody has any suggestions or fixes for these issues please let me know.
