ethernet connection issue, think could me mother board:(?

[leea123]

Hi there. have had my pc for about 6 months now from pc specialist. I noticed my internet was kinda slow and was having trouble connecting to origin client for example . Web pages was taking so long to load and sometimes even saying cant connect to the website or words of that kind although the pc does say it is connected to the internet when looking in windows network . This is using the network cable from pc into my router .

I then thought ok i would try something, so i removed the cable from back of pc and turned on the wifi . Everything started working great again , all good and no issues .I then started to think maybe a cable issue .

I then used a new network cable from router to the pc made sure the wifi was off , and still the same issues, slow loading web pages or not even connecting to the web page at all, could not start several programs that require a connection

So i have eliminated the cable as tried a new one , it works great when the pc is set on wifi . the only two options left would be router or maybe the network cable socket on the motherboard has gone up the wall .

I do not think its the router bt homehub 6 , as i have another network cable from it running into home plugs and connecting to my tv and x box and i do not have any issues at all when using them, and i did try the same port on router to the pc in fact i tried every port on the back of the router.

So i think i have to give pc specialist a call, as i cant think i can do anything else , really do not want to rma my pc, but am out of ideas . Any advice be great. thank you

Little update just plugged my laptop in to the network cable, and all working fine, its only bad when its plugged into desktop

regards
lee

It could be a duplex issue with the settings of the network card. There are times where it can get confused and select the wrong setting.

You want to make sure it's configured to full duplex and set for Gb speed (1000mb mode).

The settings you want to look at are here..

Control Panel\Network and Internet\Network Connections

In there you will see your Network Connections, right click on the LAN one and click "Properties" then click the "Configure" button then the settings you are looking for are normally under "Advanced". Every chipset is different so I don't know what to select after this point. On mine it's under "Speed & Duplex". Mine is set to Auto, as it's working fine, but you can manually select 1Gb full duplex.

If it's not that, it could be some other settings in there that's conflicting or causing issue. I wouldn't know how to guide you though, it's something you just need to see to figure out. If it's not the duplex setting it's probably best to contact PCS.

Thank you for the reply, it was under speed and duplex. I changed it but it was still the same , so changed it back to auto negotiation. Really hope it it a setting,would so miss my pc while it would be away . Will call pcs tomorrow. Thank you for your time

Open an elevated PowerShell session and enter the Get-NetAdapterAdvancedProperties command and paste a screenshot up here so we can quickly check the settings of all your network adapters to see whether anything is obviously wrong.

Just a quick update, and i can not explain it, i installed malewarebytes premium . I ran it removed any issues , and since then the issue has gone away . I do not understand how that can be related , Will keep an eye on it . Thank you

Did Malwarebytes find any malware?

 

[SpyderTracks]

If malwarebytes found issues, then it's worth doing a full windows reinstall as you're system will be compromised.

Also bear in mind, if you've got malwarebytes pro, you can't have a second real time AV scanner otherwise they'll conflict and cause system slowness, just in case you've got any other AV installed (other than windows defender which would be automatically disabled).

There is malware that injects itself into the IP stack and hijacks your DNS.

What that means in English is that it installs a bit of software that intercepts anything you do on the network and redirects some or all of it to malicious sites and services.

It sounds from the description that you might have had some similar software that wasn't quite functioning properly. It'd be handy to know what Malwarebytes found.

I was just about to add the same comment. Personally once a system has had a malware/virus infection, I treat it as totally untrustworthy. There is never any 100% guarantee that AV/AM software can absolutely remove every last trace.

Absolutely. No AV scanner is really built to truly disinfect, they claim they can, but it's by no means reliable. Their true purpose is prevention, once you've got an infection, you really need to reinstall.

Thank you all for the input, all mailware bytes found is what they call pup optional to remove . I did take a look and a lot of them was from an old virus software i had, which was total av and some from app data and documents but nothing stood out to me as anything dodgy. They was all just pup optional nothing else , but removed all just in case . i am also using windows defender along side bytes and they work well, have spoke to mailware bytes to confirm this and adjusted my settings . I also use a vpn when on net , and as far as i know have never downloaded anything a bit suspect at all .

 

[Tony1044]

It is possible that the previous AV had a firewall or some kind of other internet protection that was breaking the IP stack. Actually I just did a quick look and it looks like Total AV does do that as it mentions internet security and blocking phishing URL's.

It's also possible it had a firewall which had left remnants and was blocking access.

It is, of course, your call, but I'd be tempted to do a reinstall anyway.

A VPN doesn't do anything to protect you from downloading nasties, or visiting drive-by infection sites.

My last piece of advice is that just because we don't know we've had an infection or compromise, doesn't mean it hasn't happened. After all, we rely on our AV and AM software to tell us.

It does sound like you have good browsing habits though, which always helps.

 

[leea123]

Thank you, i can also add , i use my laptop the same way as my desktop, the only difference i never installed total av at anytime on the laptop . Thank you for your help i am considering a fresh install .

 

[Tony1044]

These days my go-to recommendation - and you'll get the same advice from others, here - is to just stick with Windows Defender.

It is as good, if not better, than paid-for products and chugs quietly away in the background.

 

[leea123]

thanks for that i agree with you, windows defender is good, so using that with bytes is the way for me to go, and as mwbytes sorted my issue i can only be happy with it working along side defender

This is the main reason I use Macrium Reflect to take nightly images of my system drive (I keep 14 generations). If I even suspect I'm infected (or if I do something dumb) I just restore the most recent image and it's gone. Simple.

One of the things I like about both OneDrive and my own personal version, Seafile, is that it keeps checkpointed deltas of files.

If they become corrupted, or you save a version you later don't want, you have the previous versions to go back to.

It doesn't replace a good backup regime but it's a great way to sidestep encryption malware, some of which doesn't notify you of the encryption until weeks or months down the line when for many places, it's started to eat into backups. Nasty and naughty to the extreme.
