Hello everyone. I have come across a very peculiar problem with my internet.
Windows 7 64-Bit Gigabyte P27K
Yesterday when i came home, i noticed that the internet was really slow, so i decided to restart the router. After the restart, my computer displayed a DNS error (which wasn't unusual for me after a restart.)
However, this time, the usual steps i took to fix this issue has caused even bigger problems.
Normally, after i restart my router and computer, the issue would resolve itself. If not, i would run the following commands in my command prompt:
ipconfig/all
ipconfig/release
ipconfig/renew
ipconfig /flushdns
ipconfig /registerdns
After that and another computer restart, it would normally resolve the issue. However, that didn't happen this time.
After the reset, i no longer got a warning icon on-top of my Internet Access tray icon, however my internet was still extremely laggy. When i diagnosed my Local Area Connection, i still got a Your computer appears to be configured correctly but the DNS server is not responding error.
When i tried to do a tracert to www.google.com.au i noticed that i was having problems with the first hop (to my router.). So, i decided to ping my router and found that i was constantly getting values above <1ms (ranging from 100-4000)
To clarify, i didn't notice that the internet was particularly slow going about my normal activities, except the when i started to download a certain show that has a lot of seeders and airs on Monday in Australia. The speed for that was terribly slow but my internet didn't lag. Hodor!
Here are some information and details on the steps i took in order to resolve this issue.
1. I am using an ethernet connection directly to Port 1 of my modem. The ethernet light is constantly flashing now.
2. The Wireless Network Connection was disabled to ensure that i don't accidentally use Wi-Fi instead of my ethernet connection.
3. Other devices connected to the router don't experience any lag. These devices range from my own Galaxy S6 to other computers on the network. Only my computer was having a problem.
4. I tried another ethernet cable to a different port, but that didn't help.
5. When i disabled the Local Area Connection and enabled the Wireless Network Connection it didn't help either. Instead, i noticed from my ipconfig that they were under different ipv4 addresses. Originally, when i was using the ethernet connection, it was 192.168.1.7 while the Wireless one was 192.168.1.6. When i enabled both of them at the same time, they had different ipv4 addresses.
6. I attempted a system restore to a few days ago when my internet wasn't having any problems but that didn't help either.
7. I was previously using Google's DNS for both my ipv4 and ipv6 but i have reset them to Obtain DNS Server Address Automatically.
8. I left my computer sitting for a while with some command prompts running and i noticed something peculiar. When i came back after a hour or so, i noticed that my ping to google was stable and i rejoiced. However, i was soon disappointed. Whenever i initiated a new connection (such as opening a web page or launching an application (such as steam) i would immediately lag on my connection to the router and consequently, to the internet.
These were the two commands that i had left running on the computer:
ping 192.168.1.254 -t and ping www.google.com.au -t
I launched these two commands so i could see when i was experiencing high latency and if that was related to the ping to my router. It was. Whenever the ping to my router spiked, my ms to google also spiked. The ping to google was always 1-10 ms higher than my router. If i left my computer alone without opening any programs that connected to the internet, my ping to the router was always normal (<1ms) while my ping to google was a stable ~25ms. However, whenever i opened a new connection (for example. from my firefox to www.google.com.au), my ping to the router would instantly spike along with my ping to google. The connection would still get established and i can see the google homepage but i would constantly lag until i closed it. Once closed, the ping would eventually drop down.
9. While i had an ongoing connection open, i couldn't even access my router page. I would get the error message: 400 Bad Request No request found. micro_httpd
When i closed all of these connections and had <1ms to my router again, i could access my router. (along with spiked latency to my router for a few seconds.) Whenever i try to access a new tab within my router control, i would also get a spike in ping. All of these problems seem to point towards an issue that was isolated to my computer. Nobody else in the house had problems accessing the internet, only this machine.
10. When i accessed the DHCP Table, i noticed that my computer had two entries in there. They were:
192.168.1.6 00:90:f5:ea:7f:64 user-PC Remains 22:25:42
192.168.1.7 24:fd:52:cd:5b:fa user-PC Remains 22:21:49
However, my wireless adapter has been disabled for quite a while.

However, if i was to open a connection to Google with firefox or internet explorer, my ping would immediately spike.
My ISP is Dodo in Australia. The are the results from my xDSL. Copying the text made it look really confusing, so i took screenshots of it.

Problems still persist. Does anybody have any ideas?
Edit: I launched Windows under Safe Mode with Networking and the problem was gone.
I'm not entirely sure what fixed the issue while the computer was in safe mode.
Once i rebooted my computer normally, the problem was back.
Does that narrow down the field of possibilities?
