Network / Sharing :: Connectivity (DNS Servers Not Responding)
Feb 7, 2014
Last night my wife's laptop couldn't connect to the internet. Error message was DNS servers not responding. I unplug power cables and Ethernet cables from cable modem and router (WRT54GL DD-WRT). That didn't seem to work. Today, she was able to get on certain text heavy websites. The WiFi icon said that she had internet access, but still very limited access and slow. I try DNS Release from router's setup page and DNS Renew. I also tried to release and renew through command prompt, but nothing has worked. I can get full access if I bypass the router and connect to my Desktop. Is my router dieing?
Here is my Desktop's ipconfig /all when connected to the router:
Microsoft Windows [Version 6.2.9200]

C:WINDOWSsystem32>ipconfig /all

I want to use third party DNS servers rather than those of my ISP. However, it takes less than a day for Windows 8 to lose the settings I painstakingly entered (awkward user interface, and long navigation to enter manually).
Can I set the DNS servers using a script, and if so how do I go about this?

Recently my computer ran into a problem, couple of days ago, I could play or view websites just fine, just that day when I came back from outside I launched my game (The secret world) and the launcher got stuck at Downloading patch information.. (which was actually trying to connect to the server for patching) It was just stuck at there, so, I tried opening the game's website for support, but surprise, I can't either..
this is the error Google Chrome shows me ERR_CONNECTION_TIMED_OUT. So I can't play nor see the website BUT, when I use a proxy in chrome, I can see the website just fine, and no, im not banned from the game..
This is what I've tried so far..
Flushing DNS
Cleaning dns cache
Resetting router / modem settings to factory
Rebooting several times
And I even restored my whole PC to fabric state (Yup, I formatted and all)

I purchased a new Windows 8, Inspiron 15 7000 series - 7537 last December. I had been using a router at a hotel for the time, and it worked correctly. When I arrived home, I had a Belkin router, and i experienced network issues in that i could not connect to the wifi. I could connect with Ethernet cable. The problem was fixed through customer support eventually, but I now have a new Comcast router, and i'm experiencing what appears to be the same or a similar issue. I can access the internet fine by wire. With wifi, it says i have access to the internet over the internet icon in the bottom right, but i cannot access webpages. I can use skype, and communicate through it.
Here is the result from the ipconfig /all :
Microsoft Windows [Version 6.2.9200]

C:Windowssystem32>ipconfig /all

I really need the wifi on this router working for this laptop. Let me note that it works on other laptops, so it should be an issue with hardware or settings on this laptop.

I have problem wit limited wireless connectivity on my laptop (Samsung) but also on my iPhone 4 and my wife`s LG optimus 5 duo all at the same time. I changed yesterday my router speedport which performed wireless connectivity problems, with a same one- and the problem is actually the same.For every 30 minutes I have limited access on my laptop, iPhone 4 and LG 5. If i restart the router it is OK for a while, and then again the same story. Someone told me to switch off wireless option on both phones, which made connectivity normal on my Samsung laptop.
I repeated, I changed two routers and the problem persists.

Now that I've upgraded to Win 8.1 my computer looses network connectivity several times a day. I can't even ping other devices on my local network. Rebooting the computer makes the problem go away (for a while). Its this computer running 8.1, none of the other computers on the network (running Win 7 or android) have the problem at the time this computer can't connect.
This is not good! If there's a way to refresh the network connection (some control panel function) that would be a not-very-good work around. Other than that it may be time to go back to Win 7.

I have a lenovo thinkpad edge E520 running on Windows 8. I have used this computer to connect to internet before but has all the sudden stopped working. I have tried connecting using a ethernet cable and also wifi but it continues to say limited access. I have tried updating the drivers and have also tried restoring the laptop to a later date but neither worked. I know my internet is working because I use the internet on my boyfriends laptop and also have playstation 3 and xbox 360 hooked up to my internet.

I'm trying to connect to a public open hotspot on my desktop that requires authentication by a web browser. I'm currently getting limited connectivity and I am not prompted that extra information is required (Like I am on this windows 7 laptop)
The windows8 drivers on my usb wireless adapter are all up to date. Troubleshooting says that I have a DNS problem, that the address doesn't exist. I've it with automatic and manual 1st 8.8.8.8 8.8.4.4 I've also tried disabling ipv6. It's so easy to connect on any other device, first issues I've had with this wi-fi, so It's safe to say it's a issue my end.

I have a PC and a tablet, both of which have Windows 8.1 installed, and are regularly updated. I prefer using the wireless connection on my PC, although I do have an active wired connection. Is there a setting somewhere that disables the wired connection automatically when the wireless is active, and also switches back to wired if the wireless disconnects? I have looked into Group Policy Editor at the wireless and wired LAN settings under Network Connections, but don't see any setting to do this automatically.

After receiving a new laptop several months ago I began experiencing wi-fi disconnection issues at times the indicator on the system tray indicates limited connectivity, that's when I know that I am about to lose the connection I use windows 8.1 so when clicking on the wi-fi signal strength indicator in the system tray the network status dialogue slide's in from the right of the screen where I pre-empt the drop off by switching the wi-fi off & on again.
Computer is acer aspire e series with a Broadcom 802.11n Wireless adapter.

I recently did an upgrade from Windows 7 Ultimate 32 Bit to Windows 8 Pro 32 Bit. I am been experiencing an issue with my wifi connectivity only on my Windows 8 Laptop (Limited Connectivity)
Apart from that the Wifi works perfectly with my Windows 7, and other mobile platforms etc. I've tried uninstalling and reinstalling the drivers and the problem still persist. I've got a Acer Travelmate 5742G
This is my Wifi Troubleshooting Report:

I am currently having serious issues connecting my windows 8 desktop to wireless internet. It runs fine when hardwired in and I have tried to reinstall drivers I have run programs ensuring me they are all up to date. The computer is a HP Pavilion m8430f. The router is a Verizon router and I believe the company that makes it is actiontec m142wr.

Some basic info:
New HP Pavilion 14 Touch w/ Windows 8.1. (purchased directly from HP)
Intel Core i5 1.7GHz/2.4GHz, 64-bit
Broadcom 802.11 bgn Wi-Fi adapter
Wireless Router: Arris TG862G Router.
My laptop was able to connect to my home router in the initial setup of the computer, but within about 1-2 hours I was disconnected entirely. A day passed and I was able to reconnect, but at noticeably slower internet speed. This lasted for about a day until, once again, it disconnected entirely this evening. Any attempt to reconnect is met with, "Can't connect to network".

For about a week now, my computer has had intermittent internet access. It'll work anywhere from about 10 seconds to 45 minutes or so before cutting out. When it disconnects, it usually corrects itself within the next minute or so, or disconnecting/reconnecting to the network, running the troubleshooter, or turning on/off wifi will correct the issue slightly quicker.
When running the troubleshooter, I've seen about every error it has. Usually "Default gateway is unavailable." Sometimes an IP error, sometimes "network cable is unplugged," sometimes it'll tell me I have a router or modem error, or to contact my ISP. It varies. I've seen up to 3 errors at once, and then the next time the Troubleshooter runs it'll give me another entirely. The network itself is fine. A number of other devices function consistently throughout the day as my PC has issues. This PC worked on this current network for about 3 weeks prior to failing.
Normally, it thinks it's connected. Sometimes it shows the yellow symbol in the bar and says no internet access. Usually depends on how long it cuts out for.
On an HP Touchscreen laptop
AMD A10-5745M APU processor
Windows 8.1, 64 bit
Qualcomm Atheros AR9485 802.11b/g/n WiFi Adapter
Security on the wireless network is WPA2-Personal with AES encryption
I've checked for viruses (none), refreshed the PC (not a full restore, but the one that does not remove files, just programs and settings), done a couple things in command prompt, and updated the driver.

What is wrong with my laptop.
I turned it on and I could not connect to the PUBLIC WIFI network that I usually connect to when I'm out. Then I tried connecting to other networks and they all just had a little piece of garbage icon on the wireless symbol.
A yellow alert sign.
I restarted my computer about 10 times, went into my device manager, used windows troubleshooting, uninstalled and rolled back my Intel Centro Wireless(M)2230 wireless driver. Nothing will work. I can`t really take a screenshot of my ip config /all.

I am using Windows 8 Professional. I am using a Dell XPS 1510 and am using a PCI Express Realtek PCIe GBE Family Expresscard.
I have already downloaded the latest driver from Realtek from 09/26/12. I have ran Windows Updates. No matter what the Realtek PCIe GBE Family Local Connection loses internet connection.
This card worked fine for months in Windows 7 Pro. The card works fine in Windows 8 Safe Mode. However, when logged into Windows 8 in normal mode, the card will allow and have internet connection for 1 min 12 secs to 1 min 32 secs, at which point the internet connection drops. The wifi and internal NIC (10/100) connection work fine. I've changed the NIC binding order. I've disabled the internal NIC, and Bluetooth (just in case) in the BIOS. I've tried uninstalling the WiFi to force using the Realtek PCIe GBE Family card.
I have ran procmon in order to try to figure out what if any application runs within the 1 min 32 sec timeframe that may interrupt the Realtek PCIe GBE Family card and have uninstalled any suspected applications. I've tried disabling services one at a time to see if it makes a difference.
I have tried DHCP and Static IP addresses.
The problem seems to be something within Windows 8. Something with Windows 8 disables the Realtek PCIe GBE Family internet connectivity. I've tried everything to keep the connection alive, internet works fine, I get perfect gigabit level speeds up until the 1 min 12 secs to 1 min 32 secs then all I get is no network connectivity.
The Windows 8 Troubleshooter is useless. Even though it is setup with static IP it says it can't find the default gateway. The issue is not with the router, somehow not being compatible with Windows 8 or something else. The card worked fine with the same router in Windows 7 and the internal NIC card works with the router in Windows 8 so its not that the router has problems with Windows 8.
I've also already disabled the "Allow the computer to turn off this device" option in the cards Power Management tab (first thing I tried). I've set the Power Management options on the laptop to be set to Maximum Performance.
Everything else with the laptop in Windows 8 seems fine, only this PCI express card that enables gigabit connection is failing. Don't want to use the slower WiFi or 10/100 connection those are too slow for what I need.

Today, my internet connection at home encountered a problem. I can connect to the WiFi but no internet access. Usually there's a yellow exclamation mark, but this one is fine, full signal but no internet access. Same thing goes to my iPod, can connect to the WiFi but no internet access.
To my surprise, all my sister's laptop and her Apple devices also the same thing, can connect but no access. I wonder what could be the problem. I use the troubleshoot on my laptop and it says "The DNS server is not responding" and it states that it can't be fix. I already restart my router but still same thing. Right now I'm using my phone's hotspot to connect to the internet and post this here.
My torrent is still downloading at full speed.

I have a Windows 8 x64 rig with a wireless card connecting to Linksys router connected to a cable modem. I also have Hamachi and Teamviewer installed, they add their own setup to the network page, don't know if they are the culprits but with DHCP I have no problem.
Everything works well until I try to set up a static IP on my PC (if I enable DHCP for IPv4 - no prob).
What I did: Set a static IP to avoid conflict with other PCs, subnet mask 255.255.255.0 (auto fills), gateway = my router's IP (192.168.1.1), DNS servers = took from my ISP's site (also tried Google public DNS).
What happens: my PC connects to the wifi as I can browse the router's settings page. But any website I try to access leads to a DNS server not responding. As soon as I reset back to obtain IP automatically everything works.

Previously I made a thread t hat when I sometimes load 2-3 tabs or more, I get page cannot be displayed and I have to refresh each of them until they load, it's like the traffic isn't enough to load several tabs at a time.. Either way troubleshooting gives me this:
Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding
In Sharing Center > click the wifi info > Properties > Networking > TCP/IPv4 Properties > All set to automatically detect, even if I inserted the DNS addresses above into manually in IPv4...
In properties I see the same being set, no mismatching DNS servers..

while ago my internet on my laptop got messed, I reset the router and the Internet went down for days, but when it came back it wasn't working for my laptop, but everything else. Trouble shooting has told me it's a DNS server not responding, and now it's telling me the wifi doesn't have a valid ip config. I've tried many things, like with the internet protocals, the command prompt fix which also hasn't worked, and I'm stuck on what to do.
When I click on my my internet protocols v4/v6 it gives me the option to install maybe that's something or not.

I want basicly to home host a VPN, and that is what i do at the moment. So i tried with my friend after i did finish the setup (i did setup the VPN in the Windows Networks interface, over "Incomming Connections"), and i did portforward 1723, and the worst is, that when my friend connects upto the VPN from his PC at his home (not Local), to my IP, then it says on my PC he is connected.
But here comes the problems, at his PC, the Network Icon turns into a yellow warning icon, and when he clicks troubleshoot, it says "DNS Server does not respond", but at my PC here, it even says he is connected to the VPN, but also says no connection over IPv4, and the same on his side.
What can we do to get a connections from my PC to his PC, over the VPN, so he can access the Internet over my Internet instead, like lets say he has a blockade on for example www.facebook.com at home (which he of course doesn't has, it is just an example), and he connects to my VPN, as he accesses my Internet instead, he can open www.facebook.com, instead of having it blocked (one of the main purposes for a VPN, and the data encryption of course).
Here some screenshots:
My PC (Language = German):
My Friends PC (Language = Norwegian):
And as you can see on my PC, it says he is connected, and as you can see on his PC, it also says he is connected, but he cant access the Internet, or anything else related to the web. Now prepare for the funny part: We were on Skype, and as he connected to the VPN, and "lost" the Internett Access, we were still talking (i guess that's because Skype still runs over the home network, while the rest tries to access internet over the VPN connection .

Recently I got a new laptop installed with windows 8. When I try to join any locally created ad hoc network(created from another laptop loaded with widows 7) to play multiplayer games(no internet connection involved) it shows limited connectivity instead of connected. when I inspected the wireless properties, I noted that my laptop sends packet but not receiving anything in return. so I tried to give ipv4 address manually rather than acquiring automatically. now my laptop both seds and receives data, but still it shows limited connectivity. I couldn't join the game.

I have a problem that when I joined my new tablet to the network it connects normally but it has some issues. It says that I am connected with limited connectivity. Also when doing an ipconfig /all it says that the DNS Server is 127.0.0.1 and there are no DNS Servers on the device. What could have happened is that along time ago there was a DC named exactly like my new device.
I renamed the device and still I am experiencing the same issues.
Another weird thing is that I can browse the internet easily but then when for example I go and log in to Skydrive it says that I do not have an internet connection.

Ive been having this problem for many months now. It started with a game called Arma3. At the time i thought it was the game that was the issue but i soon found out it was my PC.
for the rest of this thread when i say a program "freezes" what i mean is:
-The program first freezes then in the task manager the program slowly drops down to 0% CPU usage
-Sometimes the memory usage also goes down by a little bit.
-While in the frozen phase it either stays at 0% CPU usage or goes up and down between 0% and 1%.
-The length of this frozen phase varies a bit from program to program but its roughly between 5-10 minutes
The problem is games that have multiplayer crash as soon as i try to access the multiplayer. for example when i click multiplayer on the menu(in Arma3) it freezes for about 5 minutes. it then unfreezes and returns to normal loaded and the server list comes up and i can connect to a server, at which point the problem occurs again but for a shorter amount of time.
Some other Games/Programs that this happens to are:
-Battlefield 3
-Battlefield Hardline
-XPlane Flight Simulator
-War Thunder(Launcher, i cant even get into the game)
-Men Of War: Assault Squad
-Some Downloaders/Installers(when using ftp, i think)
-SkyDrive
Networking Games/Programs that it doesnt happen to are:
-Internet Browsers(Chrome,IE)
-Minecraft
-Teamspeak 3
-Visual Studio
-Most Downloaders/Installers
This problem only occurs on my PC and i have two other people in my house that have the same installation of windows 8 and are on the same network, who have never had this problem. I know the easy solution would be to reinstall windows but i dont want to have to do that and i have a problem with the windows key i bought and i wouldn't be able to activate it again(legally).

I am trying to share a specific folder on my Windows 8 computer with my Windows 7 computer. They are both on the same network connected to the same router. The Windows 8 computer is connected through ethernet, while the Windows 7 computer is connected wirelessly.
Here are my settings on my Windows 8 Computer:
This is the error I get on my Windows 7 computer:
What's up with this? On a related note, is it possible to share this folder with a specific PC, rather than "Everyone" on the network?

I am having trouble with ICS on win 8. On my old laptop (win xp) I used to be able to share my 3Connect dongle internet to connect to Xbox live. I recently got a new laptop with win 8 and whenever I share this internet connection I can never connect on my Xbox (the network to internet part fails). When everything is connected up and shared the Ethernet says 'Unidentified Network' which i believe is the cause of the problem. I've read i may require a driver update but i cannot seem to find one.
My Laptop: Toshiba Satellite C855-29N
what to do, maybe i am not setting up the connection sharing properly?

I've been trying to set up an old Savin 9033 printer through the company's router, but I couldn't find the network it's set up on from any other computer.
So I pull up Network & Sharing, see that Network Discovery is turned off.
I check it, go to click on "Save Changes" and nothing happens. I click it a few times and it kicks me back to the previous page, nothing saved. No password prompt or anything.
I double checked that all the appropriate services are running (DNS Client, SSDP Discovery, UPnP Device Host, Function Discoveryr Resource Publication, etc.) and made sure Network Discovery was allowed through Windows Firewall.
