Mobile hotspot - no internet on the "donor" device - Samsung Galaxy S5 Neo Questions & Answers

Hi.
Just got a new phone, a Samsung S5 Neo and I have a problem.
When I share my mobile connection ( wifi hotspot ) with other devices I can't use the internet on my device, no page is loading.
The devices I share the connection with have all a normal internet connection.
Never noticed this happening before on my previous phones. Is this normal or there is a problem with my phone or the operator?
Regards,
Paul

Xperia Internet connectivity issue

Hi there, my Xperia (or WM6) has an issue that everytime I try to access the Internet even connected via USB or Bluetooth to my Internet connected laptop or via WiFi on it it always make a data connection to the mobile operator instead of using the existing connection.
I have just bought it and it is an amazing phone but can't use it 100% yet. I am an old user of WM so I tried a lot of things to help but nothing solves.
Could anyone help me?
settings->connection->connection->advanced-select network
and pick my home network or something like that
not being my isp or whatever your cellphone network settings are called

[Q] Wifi/USB tethering connects, but no internet

Hi Guys,
I have the N9005 note 3 and i am with a Canadian provider (Koodo). This means that I am free to tether and have no restriction by the provider.
When I turn on the "portable wifi hotspot", I can connect to the network with my laptop, but I can't seem to get access to the internet. It has the "no internet connection" sign and I am confident that the issue is the phone and not the laptop as I've tried several other devices before.
Is there a way I can fix this?
Thanks!!

WIFI & Mobile Data Simultaneously?

Hi, New poster so if I've posted in the wrong area please don't bite
I've been connecting my phone to a smart device (miracast-ing 'direct') but as of late the connection has become unstable and generally unusable. I had the brainstorm of using an old router to stabilize the connection, this seems to have done the trick but now I'm unable to access the mobile data as WIFI has assumed priority. Please bear in mind I don't have home internet so the router is being used solely as a go between for phone and smart device. Is there any possibility of WiFi connection whilst have access to mobile data or is this just a pipedream?
Thanks in advance
You can just start a wifi network from your phone, connect the smart devices to your phones wifi and use mobile data normal as internet connection (this is standard if you start a wifi network from phone). You wouldnt even need the router with this szenario, if the wifi signal of your phone isnt strong enough you can connect your router to the phone and extend the wifi with the router.

Thanks for the reply
But creating a mobile hotspot won't help because it doesn't solve the faulty (actually non-existent) miracast connection, plus I don't need a hotspot because only the phone needs internet access. My earlier explanation was probably a bit vague.
My goal is to mirror my phone's screen but to also have internet access solely on my phone.
Phone➡Smart Device➡Display - Can't connect (used to work faultless).
Phone➡Router➡Smart Device➡Display - Connects but no mobile data available because the phone thinks the router has internet access covered.

Creating a hotspot is not for giving the other devices in your network internet access, this is the only way you can use the wifi on your phone with using mobile data at the same time. I dont know why but android devices never use mobile data when they are connected to a wifi network and there is no internet access available. So if you configure your router as a wifi repeater and setup the phone as base station, your wifi signal from phone to router should be good and you can connect your other devices to the router, the phone should see all devices in the same network if you stop the dhcp server in your router and only use the one from your phones hotspot. Should look like this :
Phone (with DHCP) <----Router---->Smart Device---> Display

Cheers will try it out.
Hopefully that sort of config is available on my router as it is loaded with a custom firmware from my old ISP provider.
Thanks

Router ISP custom firmware seems restrictive (no advanced wireless settings) plus WDS is not officially supported.
Possibly achievable but beyond my technical savvy
Thanks for the advice anyways.

Do not use WiFi 5Gz , use only 2,4Gz, and wifi 5Gz off for router and smartphone

Intranet access not working if mobile data enabled?

Hi all,
When connected to a WiFi network (isolated intranet, no internet access), Android seems to assume it's useless, and directs all data through the 3G/4G network.
For example:
- 3G/4G mobile data enabled.
- WiFi enabled, connected to intranet and is allocated a 192.168.4.xxx address.
- Android detects WiFi connection has no internet access, so i get the WiFi logo with the X through it, and a notification saying so.
- I open the web browser on the phone, try to connect to http://192.168.4.1, which times out as Android is trying to connect to that site via the mobile network.
- So I disable mobile data.
- Now when I open the web browser on the phone, try to connect to http://192.168.4.1, the site loads as it should.
It appears Android is trying to be too smart for its own good, and just completely disregards the WiFi connection if internet access isn't present.
Does anyone know how to fix this so it follows normal packet routing rules?
Thanks.

Hello
When you have activated the mobile data and you are on a intranet Android it´s smart and connect you to internet. I know that it a very boring thing but is an system specification. I´m a IT admin an on my enterprise occurs the same. The only possible solution is to shut down mobile data if it not neccesary and connect to the intranet both things are not possible.
Best Regards
