Can someone have a second opinion with me in this? I looked up sources regarding this and it is said that it is a stuck pixel THere is like a grayed out box in the monitor, I cleaned it with a soft cloth and it still is there...

Can somebody tell me what is going on with my monitor. It's a cheap N-VISION IP22v1 monitor I got last year. It does fade out eventually when I am using it but it does comeback the day after. This happened last Friday.

I forgot to say this but this was last week where every 9am - 12 am (yes, this is true, it's scheduled and also random) internet randomly crashes but it does show it is connected and I'm also using an ethernet connection. When I do use my Wi-Fi dongle on the instances of the suddenly outage is that it does connect directly to the internet without any hassle. I cleaned everything now and it's running fine which was weird. I just wanted to know and also take some precautionary measures as to why that happened. As of now, I'm currently using Xarp ARP detection set at basic level for detection. Unfortunately I can't give a screenshot for now about that when it detected a request coming from her PC to mine, Xarp isn't detecting anything yet. I'm using a TP-Link router, I also changed all the cables and I do still have an IP address when this happened (which was last week, it was very hell because it was very frequent until I just had to clean install the PC) and I can ping my router and network card.

ah her device is sending requests time to time to my PC, sorry for the misunderstanding.

In a sense, I just don't want her device to send something to my PC. Instances of reports from Xarp said that her IP was actually sending some requests over and over again to my IP address which my brother said that it might be an ARP spoof attack.

It literally cause several outages on my end. Her app was installed in my PC last time then now we have seperate devices now and sometimes it does like I don't know ARP spoof attack me? There were several instances that Xarp detected her IP address sending a lot of request from my pc and thus my internet for some reason...

it's an ESL teaching app called ClassIn, suddenly why that application runs, my PC's internet dies out suddenly and this happened a while ago when I was fixing on why my PC has like scheduled outages of internet and it was her app that was causing it. Her app was running in my PC last time before I cleaned uninstall the pc.

I just wanted to block her inbound and outbound connections or traffic with my pc because the application that she is using for teaching (ClassIn) causes the internet in my pc to go out suddenly

no no its security reasons, basically her application causes my internet to crash but everyone except me in the house can access internet which is weird.

So I want to block my sister's device's traffic because that causes my pc's internet to crash. How do you do it without using the router and only using built - in programs like windows firewall. (THIS worked with ESET but I had to result on using a firewall that was in my disposal).

That's what I concluded also when I searched about VM's im using eset's trail for now and it works, everything is working fine for 2 days now im thinking of using snort for an IDS like eset's built in IDS protection for possible ARP spoofing would you recommend snort? and paired it with a anti-virus firewall for more protection?

I'll try this out with my brother because he is the one that knows the router's username and password. Thank you for this information ::__:: but do you recommend VM's?

*UPDATE* sorry a bit late, its 12:40 AM as of 28/09/2020 and I also reinstalled windows twice to make sure that there isn't anymore viruses (because my sister used it in a jiffy with her app and we will get into it a bit) basically all of these problems were not caused by ip conflicts or faulty hardware i checked everything from pinging them from in cmd to see if there were any loss ping 8.8.8.8 -t ping 127.0.0.1 and pinging my router's ip address So my sister's app is causing the network to crash which was a Spoof attack from according to my brother and explains on to why my Instagram got hijacked last week. My brother launched a program called Xarp which they use for cybersecurity (probably) from his past job. The application or program is either Acadsoc or ClassIn (ClassIn is a virtual classroom like Zoom) and these are the 2 apps that is used by my sister for her teaching students from her agency which is Acadsoc and is requiring ClassIn as their go to program. My brother did suggest buying a better router with a built-in firewall but I said to him to hold on to it because it is going to be a joint project by the family. All I can say that my connection is getting spoof attacks which explains all of those downtimes and also "Ethernet Connected but no Internet Connection" problem that I am posting to this thread. @Aditya Dighe Thank you for your advices :'>>> they helped a ton and also @LAwLz for boosting my moral when this kept happening and to all the people that helped on this thread. If there are any recommendations and procedures you guys want to help and say here in order to prevent spoofing will be really appreciated ahahhahah, I'm sorry if I sound a bit demanding but I really don't have a single clue in cybersecurity.

I'll report to this thread upon having another disconnection For some news I used the LAN driver from my mobo's manufacturer and I am going to see if there are anymore problems occuring next. The last driver was from realtek, the 2020 version which did work but still has that occuring disconnection. Next is that I used the mobo's recommended driver from ASUS (Mobo model: H110m-d) and it worked so far. There was however another problem that occured and it was "Ethernet" was not properly configured like that (I forgot the error message), it had problems detecting the wired connection so... i reinstalled the driver which was the 2020 version and then it didn't work. Hooked up my wifi adapter thus searched the mobo's specific lan river which was a 2017 version one and it worked. I'll try and update any news if the frequent "ethernet is connected but no internet" problem is still going on tomorrow. I'm still leaning to reinstall windows though to also clear up my C : Drive and possibly fix the problem with it

An application from my sister's tutoring (named acadsoc) was actually denied to access the camera. I didn't see the log files but it is similar to what happened yesterday before I switched to BitDefender is that there were 8 blocked sites(?) from Avast and I am leaning now to the problem that my pc is now prone to dns attacks
