Wifi tethering keeps giving no internet access until restart - Galaxy Tab 2 Q&A, Help & Troubleshooting

I connect to the internet on both my laptop and my other phone via my Samsung Galaxy Tab 2 7" by wifi tethering.
Sometimes the internet works for a while and then i get that yellow exclamation mark on the wifi signal bars at the bottom right corner of my laptop screen (i am running windows 8. Same when i was running windows 7). Hover the mouse over it and it says "no internet access". So in order to get internet access to come back, i have to restart the Tab. As soon as i restart it, internet access comes back like normal. A min later, same thing happens. Internet access goes. Sometimes it goes within secs of restarting the Tab and tethering! sometimes a few minutes, sometimes hours...its just random like that. Nothing that i am doing/ru nning in spesific to cause this to happen either. It just randomly decides to go. Some days are good and some arent.
2 things are for sure...1) its not the laptop cz as soon as it goes on it, whatever other devices that are connected to the tab's interent also lose internet access. The connection never breaks though. Just the internet access. 2) Restarting the Tab immedietely fixes the ptoblem...although sometimes just temporarily.
The internet on the Tab itself works fine at all times.
Any ideas what is going on and how to fix it?

Internet Sharing on WinXP. Network connected but browsers dont work

First off, this is on Verizon. Second, this is using the USB cable. Yes, my cable and connections are fine.
Now, sometime last year I posted about not being able to get Internet Sharing working on my TP2. I had problems getting WindowsXP to install the proper drivers. Ok, I have resolved that problem finally. Got the XP Hotfix files for the RNDIS device. .........read below
I first tried without the Internet Sharing fix .cab. And then later installed the cab to see if any differences occur. The problem.... I connect my TP2 to the usb cable and turn on Internet Sharing. It connects and shows up in XP Network connections as something like "Windows Mobile Internet sharing device - LAN #3" . And it shows as connected. However, none of the web browser will work. I get network connection errors or something of the sort. Another thing, While in network connections window, I get a horrible delay when I right click and select "Properties" or "Status" on this particular connection. It sometimes takes it up to a minute before the properties window opens. Most of the time it will show an IP address, subnet mask etc.. but sometimes it shows all 0's for ip. What is causing the hang up on this? Why is it sometimes it acts like it is freezing up, but will un freeze after about 1 minute or when I choose "disconnect" on the phones IS screen? Also, why is it when I have the Status window open for that connection that sometimes it suddenly closes out on its own, and when I try to open the status window again nothing happens? I have also noticed that while IS is turned on, CPU usage constantly jumps up and down to 40%?
What do I need to configure to get this to work right? While it was connected a couple different times, I used FDC Task Manager on the phone to Ping the IP address on my computer. While monitoring the packets sent/received in the Network status window, a couple times packets were showing as received , but most of the times it wont receive any packets and Ping will just time out constantly. On the status window, I will notice multiple sent packets, but 0 packets received. I tried manually assigning DNS addresses in the TCP/IP config, but still I have the same problems.
Any IT experts here???? Please no mention of WiFi Internet Sharing. I cant afford Wifi equipment right now, I just want to solve this connection issue.
THANKS for any help in the future. I'm about ready to nuke the computer....

Problem connecting to WiFi internet

Hi,
I am xoom MZ601. It connects to internet at home just fine so i know it works. But at work, when i connect to internet, there is a pop up window that comes up asking me if I want to accept the terms and condition. Its an open connection, so it wont let me access the internet till I press accept. However, when I connect to this AP from xoom, it never pops up with that accept screen, so I cannot connect to the internet. I have tried using many different browsers (firefox, opera mini, dolphin,stock). I have disabled any pop-up blockers as well. I have also updated the tablet to the latest available OTA update.
Does anyone know of any workaround for this problem?
Thank you very much.

Wifi stops working after being left for a while (still connected)

Having an issue with the Tab 2 where you go to pick it up and start browsing after it has been sitting around a while (not sure if the time matters, but it seems like after sitting for most of the day) and the wifi is still connected, but nothing works than needs data. It acts like it would if you had not internet connection. Toggling the wifi off and on will fix the issue and notificaitons and emails start pouring in.
Anyone else have this problem? I found a similar issue on the 7.7 forums but nobody reported a solution and I am not even sure if it would have worked on the Tab 2 anyways. I am thinking about making a script that toggles the wifi automatically if it detects it can't connect to the internet. But that is a little ridiculous needing to do that. It shouldn't be losing connection in the first place.
Hi Pirate
it's a bit depending on the ROM you have installed - but since Android 4 you have a quite reliable setting. The default behavior of Android devices is to deactivate the wifi connection when it goes to sleep.
Some ROMs don't recognize the disconnection and the switch/button still shows "Wifi on" although disconnected.
First step: go to settings / wifi settings, hit the menu button (top right three dots) and check the advanced settings.
Somewhat like "Keep WLAN active in standby" - set this to always.
That should solve it already under android 4.x
If this doesn't help, look into Play Store - search for "wifi keep alive". But for the SGT 2 you shouldn't need it
Greetz - Chris
It was already set to "Always" so I don't think that will help. I will look at that app to see what it does.

wifi turns off when not in use to save battery. I think it might be a default even if you have it set to always on.

The problem is that it never comes back on. Well it shows the wifi icon and the signal and everything but it just doesn't have any data connection. Any apps that use data act like wifi is off. The only way to get it to start working again is to toggle wifi or reboot. I also forgot to mention it is the stock ROM, only rooted. It got the OTA a few days ago too and it has happened since then.
You're not alone

It's the same effing stuff people suggest to every wifi glitch out there.
To people who think it's due to the wifi sleep policy: although I've set it to always, why would wifi not resume, after screen is turned on? It's not the wifi that gets disconnected, it's the internet (or the download speed) that stops working.
To people who suggest it's a power saving feature under low battery conditions: Sorry, I've tested it while charging and with full battery.
To people with the above two arguments: Connection to some routers works perfect with the phone. Like when I turn on the hotspot on another phone, the wifi works great. Also, wifi on the other phone from the same source (laptop used as internet access point) works well.
To people who suggest resetting the router or wifi on phone: The internet does start working again, but only for a few minutes. Even if the screen is turned on, the internet may stop working mid-download.
The actual situation is that the phone disconnects from the internet, but keeps showing a connection to wifi. Like I used connectify hotspot to create an access point, and after a few minutes, the phone moved from "connected clients" list to the "previously connected clients", even as the phone showed connected to wifi with even the download arrows blinking, but no internet (or download speed). This only happens with certain sources (of wifi). And other phones may work well with the same source.
I have tried (several times and in different orders and permutations) the following to no effect:
1. Resetting the router.
2. Resetting the wifi on laptop.
3. Resetting the wifi on phone.
4. Restarting the phone and laptop.
5. Static IPs, gateways and DNSs. (Even though the problem was not with connecting to wifi and even internet works momentarily after resetting wifi).
6. Turning off items controlling wireless network in wireless connection properties.
7. Turning off firewall.
Waiting for a savior.
I know this isn't super helpful but I had the same bug you describe on the previous version of carbon. When I updated to the latest it seems to have stopped.

Same issue. also using connectify and also tried all things you have described. If you find any solution please let me know.
I had the same problem on my Huawei Honor. You need to set static IP in wifi settings (when connecting to AP, press "show advanced settings").
Mine settings were:
IP adress: 192.168.1.75 (make sure other devices are not connected with this IP)
Gateway: 192.168.1.254 (it could be different. Use the same as you're using to connect to your router)
Network prefix length: 24
DNS 1: 8.8.8.8
DNS 2: 4.4.4.4
No option for static IP in connectify

There is no option in connectify for static IP and in USB wifi dongle also there is no option to set static IP.

1. I have had the exact same issue for (atleast) the past 2 years. Have survived by repeatedly turning wifi on and off.
2. I too use connectify. This issue doesnt seem to happen on every wifi connection (just like your case). Even more specifically, it seems to happen ONLY when I connect my phone to the hotspot created via my laptop (connectify).
3. Even when the internet is actually working, some apps do not seem to recognise that(take some time to realize it is working), while others are able to connect instantly. Specifially, whatsapp is unable to send/receive messages for about 1-2 mins, after which I receive a whole bunch of messages at once.
This does not seem to be an issue due to connectify as well. I have tried creating a hotspot from my laptop without using connectify as well, but unfortunately, nothing changed. Further, this does not happen when my phone connects to a hotspot created via connectify by some other pc. The wifi and internet work perfectly fine when connected to a hotspot created via my friends computer.
Further, this problem happens only when a mobile connects to the hotspot. Doesn't occur when another laptop/PC connects (not sure about tablets).
I have looked into every nook and cranny on the internet, explored every forum for any working solution, but have been unsuccessful. In fact, this is the first place where I saw the exact same problem as mine, and was wondering if you have found any solution to it .

I'm having the exact same prob on my ZTE Grand x V 970
It started when i had kitkat and i couldnt even "fix it" restarting the wifi, i had to reset the phone in order to have my wifi work for like 2-5 mins and then stops recieving data, tried to reconnect and stays on turning on wifi.. Now i changed to the stock Rom and the problem is still there but at least now i can "fix it" restarting the wifi connection until certain point.
Issue sharing internet with Connectify from PC
Go to:
Control Panel\Network and Internet\Network and Sharing Center
On the left column, click on CHANGE ADAPTER SETTINGS.
You should be in: Control Panel\Network and Internet\Network Connections by now.
Then click on: Microsoft Virtual Miniport Adapter and click on Properties, then click on the 'Configure' button in the 'Networking' tab. From this window, go to the 'Power Management' tab and uncheck 'Allow the computer to turn off this device to save power'.
This works for me. Try this out
If this doesn't work further, you can try out mHotspot for the same purpose.
I've had the same issue, with the wifi saying it's connected even though it isn't.
This thread is 4 years old and this issue still hasn't been fixed. What a shame.
Same issue here on OnePlus 3 even after factory reset.
I have this same problem after the security patch Mid March to Jan 1, 2019. The WIFI doesn't show in the top status bar, but toggling wifi off/on fixes it till the next overnight. I did make one change to my wireless about that same time and that was moving the min connect speed from 6Mbps to 12Mbps to help with bandwidth issues being cause by devices using low speeds and having several SSID broadcast. My S7 and Tab A both work fine - so I think it was something in the security patch.

Can I bypass my mifi hotspot's "login to wifi network" popup?

I just purchased a MiFi 500 LTE from Freedompop and have been playing around with it. It seems to work good of what I need, but I have one annoying thing I would like to see if I can bypass.
Each time I connect to the mifi, my phone (nexus 5 running stock 5.1.1) first shows a wifi icon with an exclamation point and then pops up a notification asking me to manually connect to the wifi network. Sometimes, the phone will go on and connect anyway after a few second delay. Sometimes, however, the phone will not connect, and I have to tap on the icon. When I tap on the icon, a blank page will appear. Sometimes, the blank page will immediately disappear and the phone will connect to the network automatically. However, sometimes it will not, and I have to tap on three dots in the top right corner where my options are to not connect to the network or to connect to the network as is. When I chose to connect to the network as is, it connects.
Does anyone know the cause for this? Is there some setting that I have wrong on the hotspot? Or, is this just they way these mifi hotspots are supposed to work? I was hoping it would be as seamless as connecting to my wifi router at home, where it just connects automatically as soon as it is detected.
Thanks

Can't Connect to a Certain Wi-Fi Access Point, but can others

Just bought this Moto G Fast phone today, brand new, and I'm having issues connecting to Wi-Fi. Whenever I attempt to connect to a Xfinity Wi-Fi access point, it attempts to connect and tells me sign-in is required. I get to the screen where I enter in the username and password, but it then disconnects me from the access point, and takes me off the sign-in page before I can enter in the information. This happens in an endless loop. Never staying connected for more than a few seconds before it disconnects and reconnects.
I tried doing a factory reset multiple times.
I tried forgetting all wi-fi networks.
I have tried resetting the wi-fi, Bluetooth, and wireless network settings.
I tried doing a hardware Wi-Fi test, and get the green check mark.
I tried turning off my phone, waiting for thirty seconds, and turning back on my phone with the issue still existing.
I have tried resetting my phone multiple times.
I have removed my SIM card and reinserted it.
I can use my computer to connect to this Xfinity Wi-Fi access point, and then use my computer as Wi-Fi hotspot. My phone is then able to connect to my computer to access Wi-Fi to this Xfinity Wi-Fi hotspot indirectly. It however cannot connect directly to it by itself.
I'm able to connect to other Wi-Fi access points without issues, it's just Xfinity Wi-Fi access point near my home that I can no longer connect to. My computer however is able to connect to this same exact Xfinity Wi-Fi access point without issue. The connection from my computer to the Xfinity Wi-Fi access point is stable, I'm able to watch YouTube videos etc on it. However for whatever reason, sitting at the SAME exact desk my computer is at with my phone, my phone isn't able to maintain a constant connection for more than a few seconds.
I don't have physical access to the router.
Thanks for any help! I have the feeling I should just return the phone, but I don't want to pay the $49 restock fee, and this seems to be a software issue, and not a hardware issue, so I'm not sure anything is wrong with the device from a hardware perspective.
