So judging by the quick search, many people have this problem on many different phones, and no solution was found.
I know I've had this problem with my old SGS 1, and even Nexus One.
Same problem on my SGS II, tethering to many different desktops and laptops.
So it seems to be android-specific, or Windows specific problem, really.
Basically, when you tether with USB, first several minutes all is well and speed is good, but in about 5-10 minutes, traffic from the phone just stops.
Phone still shows tethering ON, PC still thinks it's connected, but nothing loads, it doesn't disconnect, it just drops to speed or 0 kbps.
The only way to restore it is to disable tether and reconnect.
Anybody has any idea why would this occur and how to prevent it?
Does it say no internet connection on the network indicator on the bottom right of the notification center? My guess is your carrier has an issue with tethering. I see your on AT&T. Do they have a plan that is specifically for tethering?

No internet connectivity loss is indicated in windows, it still thinks it has a good internet connection. I'm assuming that after a while, it will detect that although there's a connection, there's no actual traffic flowing through it, and will say that there's an issue... but for a long time, it's simply as if I'm connected, but actual speed is at 0kbps.
Browser tries to load pages and times out in 10-30 seconds.
Unfortunately (or fortunately) this definitely doesn't have anything to do with AT&T. I have unlimited grandfathered plan with AT&T and a custom rom, AT&T has no idea that I'm tethering. Internet on the phone is still working fine.
I kinda feels as if the usb tether drivers in windows (RDIS or whatever it's called) simply gives up after a while. Or maybe it's the android tether process that "forgets" what it's supposed to be doing.
you are running a stock ROM right?

Nope, latest CheckROM.
But as I've said, I had same problem with Captivate and other ROMs on SGS2 =(
i haven't found a custom rom where tethering fully works....thats why i went back to stock
Have the same problem on BOTH my Huawei ideos U8150 and my HTC sensation.
My wirelessly tethered devices still work flawlessly but my USB tethered desktop disconnects after a few minutes. Screen time out set to Max in case something in the phone went to sleep but no difference. Definitely not a network problem as my operator confirmed but an android (or windows problem) .
I even set USB Port power settings to always stay awake.
Hope we can find a solution to this.

i got the same problem under ICS. tried on stock ZSLPE and custom XXLPQ firmwares. both do not work!
my stock gingerbread was able to work flawlessly without disconnection problem on the same pc. wtf is happening?!
I have Samsung Galaxy S Plus.
I am facing exactly the same problem.
Have tried different ROM's around 5, 3 were custom ROM's.
Looks like Android OS issue.

I had this problem on both my Samsung Charge(Stock app 2.3.6), and my Motorola Razr(Stock app 4.0.4). I believe it is a driver issue inside windows. It seems less of a problem on the Motorola phone as I get a few hours of USB tether before it exhibits the same problem whereas the charge started after a couple of minutes. ie. Phone has data and can access web, computer thinks its connected to the web and okay, but any attempts to connect to the internet from the pc fails.
The wireless tether works fine and does not exhibit the same issues so I would suggest you use wifi tether. I don't know if wifi tether uses more or less power than usb tether (assuming your phone is connected to computer and charging). If I get some more free time in the next few weeks I might try and do an analysis.

I've had this problems with pretty much every Samsung phone I had.
I have HTC One X now, and it doesn't have this problem. So something with Samsung drivers, I think.
Cool fact - HTC even has a one-click reverse tethering. So cool.
I have the same problem, but can't find out, where (windows or android) is it.
What I have:
Motorola Atrix (rooted with SuperOneClick, stock ROM)
PC with Windows XP x64 without WIFI
The only RNDIS drivers I could find was HTC RNDIS (for XPx64)
Situation:
I'm living in hostel for one month, and there is only WIFI internet here, so I tried to get my phone WIFI to tether into USB
What have I done:
Connected to WIFI over phone.
Turned USB tethering ON.
By default WIFI is not tethered to USB, so I found that turning USB tethering ON creates usb1 network and WIFI is eth0. Then I configured NAT by iptables on my phone to accept and forward connection from PC (usb1) to WIFI (eth0). [usb0 on Atrix is for Motorola Portal, didn't try yet to connect to internet throught portal connection, not USB tethering]
The problem in short:
At the begining everything works fine. But when many connection threads are opened (didn't look for that many count) connection stops. As it was already mensioned, PC thinks it is connected, on phone USB tethering is still ON, even more - ifconfig still shows the connection. The only diffrenece is that "ping 192.168.42.129 -t" on PC (192.168.42.129 is usb1 IP on phone) starts showing "Request timed out" messages. On the other side - from my phone, I cannot ping my PC either. So connection is like broken, no traffic can be passed, but both sides sees they are ON.
After turning off USB tethering, PC sees connection is off immediately and the Local Area Connection #23 is gone. After turning on USB tethering everything comes back to the beginning.
Current workaround (for me):
I am using VPS service, so I open dynamic SSH tunnel over putty, and use it as my SOCKS5 proxy. The worst thing is that not all programs can use proxies, and when I use such program it tries to crash my connection.
Sorry for my english, it is foreign language for me, if anything is not understandable or you need more test from me, please ask, I will try to do my best.

Hi,
I had the same problem with my Android Phone - P999 running Cyanogenmod 7.2
I had to go into usb debugging screen to adjust the Display power Settings to - Always ON when Charging - Option.
There is probably some power setting in your device that allows you to do that as well.
Basically Power Saving (Screen Off) Powers OFF the Tether.
Ensuring the Screen is ON while Charging (it charges while plugged into a usb port) ensures the Tether stays ON ALL the TIME!
Hope this helps you.
Took me quite awhile of messing around to find the right option.
I do have a similar problem but it's not time-dependant.
Phone:
Nexus 4 mako
AOKP JB-MR1 Build 6
franco kernel 3.4.0 build #121
Situation:
I use FolderSync to backup my sdcard to my Windows 7 FTP server. The reason for doing this over USB Tether is that I get speeds at around 14MB/s instead of 1,2MB/s over WiFi.
I noticed that it doesn't really matter how long tether is connected and nothing really happens as long as FolderSync is scanning the folders on the ftp server at low bandwidth. However once a larger file is transferred the connection is almost sure to break and show the symptoms described by the other posters (interface still up, just no packets being received at either end).
So I assume that some driver (either on Android or Windows) chokes on certain packets and then just dies. Anyone got an Idea how to tell which device causes the problem to investigate further?
I also noticed that if I had ADB enabled before starting USB Tether that the tether connection on the android will be disabled once the failure occurs.
I have problem with my realme c2 when i connect it to pc via usb tethering, it connects it running ok. if i make screen on by playing youtube or any video on it run but as soon as screen sleep it disconnect after some time
I'm a bit late to this, but for anyone else still having this problem:
in Developer options of my phone(Redmi note 11) under Networking, there is an option called "Always keep mobile data on". Turning this on should fix the issue
@Denav
This doesn't work for me. I have a Moto G Power 2021 and that option is already checked.

Were you able to figure out the issue? I'm having trouble as well. Mine disconnects after a certain time period and the times seems to be random. I've played around with the dev options and other cables and still having same issue. It seems to happen with mac and windows laptops.
Hi,
I have the strangest problem:
there is some sort of a problem in the combination of my phone and my laptop (Dell 5110N with Intel(R) Centrino(R) Wireless-N 1030).
If i enable tethering on my phone, and connect to it on my laptop, internet browsing doesnt work, but every other program that uses the internet seems to be working - say Dropbox keeps uploading files.
I've tried on 3 different internet browsers, and the problem is only local to my specific phone (my laptop works wifi with other tethering phones) and other devices (say my friend's galaxy s3) seems to be able to browse the internet while being tethered to my phone.
I literary have no idea whats going on and what can be dont to solve it, i'd love to get some help if possible.
thanks alot!

To make sure it is not a DNS problem you should try with ICMP from your notebook:
1. does ping gmail.com work ?
2. does ping 173.194.35.53 work ?
If one of these does not work, install LanDroid from Google Play and try the pings from your phone.
Hi all
I've setup VPn tunnels to my office on my S9+. I've setup a PPTP from the built in client and IPsec and SSL from the Fortinet Client and none of them are working.
I'm sure that authentications are correct as I use same settings on my laptop running windows 10 and on a iPhone 7 plus.
Anyone with the same problem?
This might not help you exactly but there seems to be an issue with the stock ROM and VPNs. Adguard, which blocks ads via VPN, was also having the same issue and the devs have reported it to Samsung from what I understand. The fix will probably come during a later update since VPN issues are a bigndeal, especially for people who need to use their devices in a corporate environment.
My VPNs include one PPTP and one IPSec/PSK, and they both connect without issues on four different Verizon S9+ phones.

Hi
same here . It's little different for me
PPTP work with S9 but in hotspot, i can't connect to PPTP VPN on my laptop with wifi of S9 !
There is a really problem with PPTP ...

Hola
I just wanted to give you a heads up that Adguard dev's have figured out a temporary workaround to make the their VPN ad blocking features stick. You'll need to check their forums for the actual setting (or use their nightly release which has the setting enabled by default). I have this setting enabled and now I am able to browse ad free for the most part without issues.
I've just update the phone and it's now working yet. Besides that the problem is even worst because I can't even connect VPNs on my laptop if using the phone as hotspot.
I've reported to Samsung and I'm waiting for a call and a remote assistence but if I can get a fix in a few days the phone will be returned because this is a big issue for my work.

I used this functionality fairly frequently with my (Verizon) S8+.
I've just completed about an hour of testing with my (Verizon) S9+.
I tried the USB tether, the Bluetooth tether, and the Hotspot networking on the phone. In each case I established a network connection to the public Internet without issue.
The VPN connections from my Windows 10 system, however - using that S9+ connection - all fail now with one exception.
The PPTP, L2TP/PSK and IKEv2 connections (that all work[ed] with my S8+) will not connect using my S9+.
The one exception is the Microsoft-specific SSTP variant, which tunnels over port-443. That one will connect with the S9+ in all three networking scenarios - USB, bluetooth and Hotspot WiFi.
This seems to indicate that the new phone does not pass TCP port 1723 and/or GRE 47 (PPTP) and UDP ports 500 and/or 4500 (L2TP and IKEv2) through it's network tethering and the WiFi connections.
Bummer.
At least I can still use SSTP to get to my server resources - which is 90% of my VPN needs anyway - but the other connections are dead now.
Connections FROM the phone, using it's built-in PPTP and L2TP profiles to host networks, continue to work properly on the S9+ -- as they did on the S8+.

That is the Snapdragon version? Does it have a special ROM from Verizon or is the stock Samsung?
Maybe that is the difference

Stock Verizon (SD845 8.0) S9+ compared with a stock Verizon (SD835 7.0) S8+. I suppose the difference might be explained by going from Android 7 to Android 8, but I have no way of testing that hypothesis at this time.
(The last phone I modified was a 2013 Motorola RAZR. I've subsequently switched to using my phones as phones, rather than as a hobby. )
If someone has a different experience with employing a networked platform's VPN while using a similar phone in a tethered or hotspot configuration, it would interesting to know.
My own successes with the phone's built-in VPN (PPTP and L2TP) - as separate from the scenario described above -
apparently differ from those of others in this thread for reasons I cannot explain.
I'm in the same boat - a new S9 and can't connect to my work VPN when using the phone as a hotspot. It works fine on S8 and Iphones. Does anyone know how to fix this? This is a critical issue for me as I work remotely quite a bit.

I think there is no fix yet. I had someone from Samsung support connected to my S9 last Tuesday and they could not find anything so they escalated the problem inside Samsung but until now no further news.

CPU - Exynos 9810 - 2,7 GHz, its on Croatian network - T-Com ( T-mobile ) - locked.
New update in germany : G960FXXS1ARD1
Maybe a good patch ...
My S9 unlocked (SD) can connect to my L2TP/Ipsec VPN but disconnects within a minute or so (even if the connection is under constant use.) I have another Anrdoid 7 device (and a Windows 10 laptop) that has no problem with the same VPN/router/WiFi combination and can stay connected for hours. I don't know how to escalate this with Samsung in a way where they just don't blame my other hardware.

So I have had my Galaxy Tab S7 (non +) for a while now, and overall, am very happy with it. I have only one problem, using a Linux machine for work and wanting to VNC to it, to use my tablet as a second screen (with an Headless-Ghost-Display aka dummy HDMI plug).
Regardless of my specific use case, any VNC connection that I try to establish over TCP/UDP, using my Galaxy Tab S7 as the client, behaves VERY oddly. First, it will work for like 1-10 seconds, then the connection cuts out and the VNC screen freezes on the tablet (not the actual tab hardware freezes, really just the VNC image), while logs on Host and Client still act like the connection is just fine. Only when disconnecting the frozen VNC session from the Tab Client, does the Host SOMETIMES detect that the connection is lost (sometimes, the host still doesn't realize it until I shut the vnc server down by force).
And even weirder, it then, 9/10 times, completely messes with the hosts Wi-Fi connection, and makes it unable to reach any sites before resetting the Wi-Fi connection.
The issue does NOT seem to be the host computer, as it happens with other LINUX hosts as well (oddly, any remote connection from the Tab to Windows works just fine).
The issue is NOT with any specific VNC client I use, as I tried A LOT and it happens on all of them. (oh, and I also tried many VNC servers, including NoMachine with it's own NX protocol, same story)
The issue also does not seem to be with my network, since connecting to the same host laptop, or any other VNC host using any other client device on the same network, works just fine.
The issue seems to be something specific to VCN connections that happens on the Galaxy Tab S7. And only going over TCP/UDP. Using a ADB reverse connection to have a wired VNC connection with the Tab S7 works just fine (be it kinda slow and sluggish sometimes).
This is as far as I can manage to track the problem down, since, as described above, any log of any host or client doesn't really give any usable error messages and just acts like everything is fine until the connection is forced shut. After a lot of digging, I found few others who did report a similar problem, but no one had any solution.
My only guess at this point, is that the KNOX security Samsung built in has some kind of problem with it? And as far as I know, on the Galaxy Tab S7, that's built into a hardware ship?
Maybe someone here has a neat idea? This is kinda frustrating and baffling to me :O
Hello. I have an older LG TV.
LG 43UJ6307 I find that my S23 ultra cannot connect to the TV on the WiFi network. Wireless DEX mode also does not work. The smart view function does not work either. Before that, I had an S22 ultra device and it communicated perfectly with this TV. What could be the problem?

Yeah, i have the same problems. To make it works, you need to reconnect the wifi connection by entering password again. It is really anoying coz we have to do it everytime

Thanks. Now I know it's not a unique error. We hope it will be fixed in the next update.
The update didn't solve the problem either. I can't get the device (DEX) to work no matter what I do. The S22 ultra worked without any problems with the same TV on the same WiFi network. For example, I also read on reddit that many people have a problem. What makes it work for some and not for others?
