Network / Sharing :: IPV4 Settings Revert Automatically - How To Stop
May 23, 2014
I signed up for a DNS service a while back. When I stopped using their service I removed their DNS entry from the ipv4 settings and considered it done (this was all they stated for install/uninstall, just update the DNS in ipv4)
At random, the PC will revert back to their DNS server. I have no virus (Malewarebytes Pro), my hosts file is empty.
Here's what I've done:
1) Removed it from ipv4 settings manually and reset to Obtain DNS Automatically
2) Open cmd as admin and ran the following sequence:
ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
netsh winsock reset
netsh int ip reset
3) Reboot
On reboot, everything is normal, anywhere from 24 hours to 30 DAYS later it automatically reverts back to their DNS servers. I am on a .edu domain. I do not have access to the router, but I never modified anything in the router. Why my PC keeps reverting to their DNS servers?
I have an external HDD that I like to store music and pictures and videos on. But I also put personal stuff on it like homework or notes I write to myself. I'm sharing the entire drive across my home network. So they have access to everything. Even the stuff I dont want them to have access to.
Can I stop sharing that one specific folder on the drive? Or do I just have to take it off the drive and put it on my local disc? I right click on the folder I dont want to share. And it says "sharing" Then I hover over it. "Stop sharing" I click that. But I test it on my sister's laptop and it still is accessible. How do I hide that folder from my home network?
Have Divco PVR with wifi, and win 8 cannot access it easily, my old win 7 laptop can find it all the time no problems, and can see the win 8 laptop and the win 8 can see the win 7 laptop. Originally the win 8 machine could only ping the PVR using the IP address, but ping by name fails.
I followed the advice about changing Network Security LAN Manager authentication level etc. plus in Ethernet properties I un-ticked Microsoft LLDP Protocol Driver to make it the same as win 7. After all these I managed to get it to see the PVR when I typed in the IP address in the address bar in explorer at the Network page. I then mapped the folder, which is working, but this is a rather clunky solution. Question why can't win 8 just find the PVR like win 7.
Is there a way to setup network profiles or something so that when I bring my Surface Pro to work and connect to the wireless network there it will use the static ip address I have but when I disconnect and then connect to my home wifi it will go back to DHCP? On my MacBook Pro I can go into the network settings and change the location profile I have setup for networks but I don't see anything like this for Windows 8.
I have a Netgear WN111 wireless adapter on my PC. Since installing Windows 8.1 it doesn't connect automatically to the router. The PC says there are no connections available, so I can't even click on the router to try to connect. If I pull the adapter out and push it back into the USB port it connects automatically. Also, when I switch the PC off, the LED on the adapter continues to flash, so I have to pull it out and plug it in again to stop that. I've tried troubleshooting, compatibility check, reinstalling the driver and uninstalling the driver and getting Windows to install one itself.
I have recently upgraded from windows 7 to windows 8 on my lenovo z470. Recently I have noticed that when I switch on my laptop with AC power (with battery removed), wifi does not automatically start up. I have to manually switch on the wifi through the hot key fn + F5. However, this does not happen if I run on battery without AC power. The wifi will have automatically started and connected. I have untick the network adapter properties of "allow the computer to turn off this device to save power. I have also ensured the WLAN AutoConfig is set to automatic.
Whenever I boot up my computer, I always have to go and connect to the internet. It doesn't automatically connect to the internet. I don't want to do this anymore. I tried clicking "Connect Automatically," but that didn't solve the problem. I also tried troubleshooting. It found some problems, and it was the problems were fixed but it still doesn't work.
I would prefer that certain files (like Tax and financial documents ) be stored locally. Can this be accomplished if I save the documents within the program I am using with "save as" then specify a location other than the C drive where the OS is located?
There are too many tap windows adapters and tap win32 adapters in my network and sharing centre> network adapter. it keeps increasing and decreasing automatically. but i only need ethernet to connect to my broadband. how to get rid of these?
I purchased a GMYLE Windows media remote to control dvd software on my computer which works fine but the remotes nav, play and pause buttons etc also at the same time controls iTunes, is there a way to stop the remote controlling iTunes?
Just some info, obviously it does not happen when iTunes is closed but I like to keep it running all the time to download podcasts in the background and don't really want to keep closing it when I want to watch a dvd.
Also I went into iTunes/preferences/devices and ticked the box "only allow paired or home sharing remotes to control itunes" but every time I open iTunes preferences again the box is un-ticked.
Having a strange issue with Onedrive. If I drag/drop files into my "local machine" onedrive folder it automatically syncs up with my onedrive account in the cloud. So the same files are both on my home system and in the cloud. That works. I can log on thru my browser at the onedrive site and log on, copy and download files...upload thru the browser and it will also show up on my local harddrive....so that works too.
The issue I'm having is if I use my metro tile screen, click on onedrive app, it opens up, I can see all the files in my onedrive account.....however if I right click while in app, then click upload it opens up my folder, I can pick the file I wish to upload and click "add to onedrive" nothing ever gets uploaded. No error message or anything, just nothing happens when using the app. No files ever show up or get uploaded. I can also pick a file using the onedrive app (from the cloud) and click download (to my local system), it allows me to pick the destination and hit OK, but I get an message " the file couldn't be saved" no matter where I decide to put it. So while onedrive is working for the most part if I bypass the windows 8 metro app, it is not working inside the app itself.
It was working earlier but couple of hours later when I booted up my Windows 8 laptop.. There was a red x on the network I was trying to connect to and a message saying my computer settings not matching.
I looked it up on youtube and I tried selecting "No authentication" and for encryption type I chose "None". But still didn't work.
Sometimes it would say limited first then when I try to reconnect the message above will appear.
I cannot connect to my wireless anymore (all other devices in my home do) since windows has automatically installed the drivers for my canon printer.
In PC setting i do not have the button wireless anymore (i am pretty sure that i had it last week). Wi-Fi (Qualcomm Atheros AR964x) is in my network connections, but cannot connect. Diagnoses says problem with wireess adapter or access point.
So what did i do until now : I have restarted the whole interne installation ( rounter, and all other devices) many times Atheros driver is up to date and device status is "working properly"
i dont know anymore what to do more (except switching to linux and not being able to use some commerical software i rely on for my work) :-(
Network Location - Set to Private or Public in Windows 8
I have a home network, several PCs connected to a modem/router (all with Ethernet cables), with ADSL access.
One PC has got Windows 8.1, with network settings as "private network", with sharing ("find devices and content") turned on. I am thinking about turning it off, to increase security, since I don't need to share files an printers.
My questions: 1) There is no risk to damage Windows by turning sharing on or off, with that "find devices and content" option in Windows 8.1? 2) After changing the sharing settings, I do not need to change any settings in Windows Firewall, such as resetting it to default?
I do a lot of AV system programming, which generally involves having to set my IP address for either my Ethernet port or WiFi card to manual IPs temporarily. I am having an issue on a relatively clean install of Windows 8 Pro that after I change my IP, when I go back into TCP/IP v4 to change it back to DHCP, it is already set to automatic... but if I right click on the connection icon and go to Status, it still has the static address. I tried to set it to another manual address and to hopefully go back in to revert, but that doesn't work.
The ONLY thing that seems to work is removing the NIC from Device Manager and then re-scanning for hardware changes where it will be automatically detected with DHCP enabled by default.
WiFi card is Intel Centrino Ultimate-N 6300 AGN.
Ethernet NIC is a Broadcom NetXtreme 57??.
I've got the latest available drivers, and using generic ones doesn't work. It's also on both NICs so I don't it is a driver issue.
There is this peculiar problem I'm facing with MTU settings.
I'm using PPPoE with wifi enabled on Windows 8.1.
Couple of months back: ADSL MTU setting was promptly set to 1492 (8 bytes for PPPoE header discounted). All of a sudden, yahoo mail was not accessible.
When I tried
Code: ping -f -l 1464 mail.yahoo.comPacket needs to be fragmented but DF set. Packet needs to be fragmented but DF set.Packet needs to be fragmented but DF set.
Packet size of 1464 (MTU:1492 - 28 bytes for adjusting different header size) is big. So decided to change MTU.
I checked for various packet sizes; First ping was OK for packet size of 1452. So MTU can be set at 1480.
I changed the MTU to 1480 in modem setting and restarted.
When connected, I tried yahoo mail again - and again failed.
I checked the MTU which is set at 1480. I tried ping with packet size of 1452 and got surprise. I got "Packet needs fragment" again. The same size was working earlier.
I repeated the process. Now the MTU came to 1460. I set the MTU again in modem and restart and try yahoo mail again to get the same failure.
Again I ping with packet size 1432. Nope. Got "Needs fragment" error.
Changed MTU setting in Modem to 1400 - retry cycle - same issue. Changed MTU setting in model to 1300 - retry - same issue.
Then I came across setting MTU for interfaces in PC. So reverted the MTU to 1492 in modem.
Set the PC interface MTU as below. I set it for WiFi interface as I was using wireless Internet access.
Code: netsh interface ipv4 set subinterface "Wi-Fi" mtu=1460 store=persistent
This solved the problem.
Today I couldn't access yahoo mail. Checked the MTU setting for PC wifi interface. It has been reverted to 1500 (default). May be some windows update did that.
I set it back to 1460. Tried to access yahoo mail. Still not accessible.
Checked the ping with size of 1432 (for MTU 1460). Got "Needs fragment" error. Checked ping with packet size 1400 - OK - change interface MTU to 1420 - Still couldn't access yahoo. Checked ping with pkt size 1400 - now not OK. Checked ping pkt size 1360 - OK - Change interface MTU to 1300 - still couldn't access yahoo mail. Checked ping pkt size of 1360 - now not OK.
This seems to be vicious cycle. What is happening?
I just got a network usb adapter for my new Windows 8 built PC. In the devices area of the control panel it shows the network adapter as installed, and working. However, when I got to PC Settings there are no wireless settings shown, and unlike my other computers around the house I can't find my network or any other networks which is very stranger since I live in an apartment and I'm surrounded by like 20 different networks.
Something keeps changing my proxy settings. Every time I change it to "Automatically detect settings", something is changing it to "Use a proxy server for your LAN..."
I have installed Windows 8.1 on my laptop. My laptop is Hp 6510b. Windows 8.1 is working fine for me. But the only issue I am facing is that I am unable to see my Bluetooth in Settings. Hence I am unable to transfer files. My android is also not searching my laptop.
So I'm rolling along the internet and I start noticing that the wifi bars in the lower corner have gone down to 4. My internet is running slower and when I log on and play online games, the local server which gave me a 50 ping is now jumped up to about 300-800 easily...
So I run trouble shooter (and malware bytes) and this gem pops up:
"Windows cannot automatically detect this network's proxy settings."
I run google chrome as my internet browser, but as of late Norton has been blocking chrome and my wife started using Internet Explorer...but when we disable Norton, Chrome works fine.
I'm using Win 8 Pro and i'm on a Private network which happens to be my Home Network. I'm having problem saving HomeGroup settings; I went through Change Advanced Sharing Settings then I checked Turn on network discovery and Turn on file and printer sharing, I clicked save and but when I return to the setting page again, the settings are not saved.
I've tried this several times but nothing seems to be working out. The same thing still happens when I go through Charms >> Change PC Settings >> HomeGroup >>Libraries and Devices.
The Windows App Store will not open. It spends a while thinking about it, then eventually times out. I would like to update to 8.1, but I think this is evidence of a bigger issue.
I think the real problem in my proxy settings in IE. The LAN settings have the Use Proxy Server permanently checked. No matter what I try, it wont uncheck. I have tried selecting the automatically detect settings box and putting in a dummy config. I ran Malware sweeps, ran virus sweeps, I removed any IE Add-ons. Reset IE. But it still wont let me uncheck that box..
It looks like there is a manual override within the Registry.
My homegroup wont let me allow devices for some reason. I go to settings in the control panel and try to change it and the window just closes then I go to windows 8 settings in homegroup and I see this (attachment) and its grayed out and locked. What do I do?
