Wifi + 3G/4G simultaneously? - Samsung Galaxy Tab S3 Questions & Answers

Hi,
my problem: I'm using my Tab3 in an aircraft for navigation. A anti collision device (FLARM/ADS) is connected via Wifi. That works fine.
BUT unfortunately I cannot connect to the web via 3G/4G at the same time.
I tried to set "Use always mobile data" in developer settings... no success.
As long as Wifi is on no chance to connect via mobile Data.
Is ther any chance to solve my problem? THX for your help!

Searching for WiFi Manager App

Hi,
i don't know if this is the correct board but I am searching for something like a WiFi Manager.
My Problem: Usually, I am using only my home network via Wifi and if I am on the road, i am using my mobile data plan. At my university there are some rooms, where i cant receive any mobile data connection. The only possibility to connect to the internet is via WPA2 WiFi but if I enter the settings for this network it also connects to this network any time I am in range of it (so when i am traveling through the city, it allways switches on an off and I dont get a stable connection.
Entering and deleting the university wifi anytime is a bit ugly so I am searching for a possibility, how I could enter my university-WLAN-Information but enable this network only, when I need it.
Thanks in advance,
Cmoe
try market from your phone or market.android.com and search for wifi manager ... it is app I use, but there is lot more apps ...

[Q] WiFi issues

Hi,
I have the following issues with my Razr:
1. When connecting to my home network, sometimes the WiFi logo won't turn blue. This causes google talk to be unable to sign in. However the phone is connected to the network, internet browsing with Dolphin and Market work fine. Rebooting fixes the issue, when connecting now the WiFi logo turns blue as soon as connected and all is good.
2. I can't connect to my university's wifi: it is an 802.1x secured with PEAP and uses MSCHAPV2. When I set up the connecting (which i have to do manually by long pressing network -> modify settings) it fails to connect (says connecting to... then Disconnected). Weird thing is when modifying the network again, the settings are screwed up (e.g. set to use TLS, MSCHAPV2 unselected).
Does anybody have any ideas what to do about these (except for waiting for an update?) I am using the 651.73.18-version, so not updated so far...
Also, WiFi strength seems rather crappy with the Razr, i'm only getting ok signals where i used to get good ones with my desire and fail to connect when my cheap hp netbook connects fine...
Thanks lots for any help!!

WiFi 802.11n connection problem

Hi there!
Does anybody have a problem with connection to 802.11n network?
I can't connect to any 802.11n networks, but 802.11g is working fine. If I switch my router to "Only 802.11n" mode - SGS III is seeing the network but can't connect.
I have tested it on LF6, LFB and CM9 (lastest nightly)
My Notebook and GALAXY NOTE work fine with 802.11n.11n.
What's the problem?
I have had no issues with 802.11n networks; have tested a few.
Try going in to Wi-Fi service mode (*#0011# in keypad (may not work on custom roms), then select menu button, and Wi-Fi at the bottom; toggle power save mode off (default is on); try connecting again - this has helped me connected to some networks previously that didn't connect.
I have the same problem since I updated to Omega 8.1 based on lfb.

Ok. Thank you. I will try.
I have tried to switch WiFi power save mode off, but 802.11n doesn't work.
For me it is a really big problem.
Also I have already installed XXBLG1. 802.11n on it is not working too!
Guys, please, help.
HTC ONE X WiFi Connecting Problem
Hi all,
the following problem: I´ve bought a ONE X and want to log into the w-lan of my company which is secured with this 802.1x encryption. With my HTC HD2 (Leo) I just entered username and password, and there was no problem. The first that the ONE X requires is to set up a screen lock and still builds no connection. There isonly the message: Connecting ...
Tried with several Roms (HD revolution, Cahrmeleon, MIUI) but always the same. Have already edited the wpa.supplicant.config file and also tried with WIFI Advanced Configuration Editor.
Anybody got an idea whis is?
I have exactly the same problem! I think it is an hardware problem! I just wait a few days hoping its an software problem!

No Wi-Fi access in the 802.11n standard, and at a frequency of 5GHz.
To solve this problem is easy. Just follow the instructions:
1. Put with Google Play free program wifixmanager.
2. Turn off Wi-Fi.
2. Run. Push Install WiFix on request give the program as root.
3. Reboot.
4. Open your default dialer (Phone). Attention! Only regular dialer, do not use third-party applications. We type the code *#94349# and press "Call"
5. Wi-Fi reconnects.
6. Voila.
It is also recommended to the country code Wifix manager put EU, instead of the U.S..
If after the restart when connected to wi-fi internet does not work, turn the wi-fi or again to type *#94349# (*#WIFIX#).

Data connection not working when connected to wifi

Hi all,
i've got this big problem and i dunno how to solve it.
Stock rom, MIUI 12.0.3, no root, developer options active.
I ran into this annoying bug months ago, while trying to get my car's android auto working with my phone without using usb cable.
I managed to connect my Mi 8 lite with the car via wifi connection; made it enabling Android Auto developer options (otherwise it wolud let me connect only with cable). Unfortunately once connected everything doesn't work, because there is no data: while wifi is on AND connected, my phone doesn't "want" to use my mobile data, even if i force data use by setting "mobile data always on" option in developer options.
I noticed this is not a problem of my car's infotainmnet, infact it happens also if i connect my phone to my wifi network unplugging phone's line cable (and so internet data ) from my router. Also in this case, with phone mobile data always active, my phone will stay connected to my wifi (which has no internet) and won't use my mobile data.
Does anyone have any idea/suggestion or know what i'm doing wrong?
Thx in advance for reading
