HI, I recently bought and set up my own computer, (see at http://pcpartpicker.com/b/G1U ) but its been having strange problems with my internet connection.

I'm using a CAT6e+ Ethernet cable plugged directly into the wall of my college apartment (which says that its a CAT5e+) and it works just fine, about half of the time... Once and a while it will refuse to open up my homepage on Firefox (the default) or will refuse to go to any page NOT in my favorites bar, BUT WILL allow my to move autonomously within any sites that are on my favorites bar.

For example, when i have this problem it will let me open up my outlook email account and send a receive messages or use Facebook normally but won't allow me to search Google or open up a read-me file for a computer game or anything like that.

My motherboard came with the "Killer Network Manager" application and it seems to do more or less what it says that it should do, I can play online games with a very low ping anytime I want even if only moments before my browser was refusing to even show me the homepage.

I've tried using Chrome and even Internet Explorer instead and this doesn't seem to do any good.

And moreover there seems to be no rhyme or reason to when the browser refuses to work. It will be out for a couple of hours and I'll come back and it still won't work and then other times it will stop working for just half an hour and I'll try to show someone how my network connection is crapping out on me and it will work first try. Its truly frustrating.

What steps should I take to fix this problem?
Is the Killer Network Manager to blame or is there some other underlying problem?

I'd uninstall the program anyway and see what effect it has. considering a decent cabled connection will get a 1ms ping I very much doubt the program is doing anything that will make a difference.

It sounds like you have some form of intermittent DNS issue but its tough to say for sure.

These so called gaming network manages are mostly hype. They can only control what a single machine is doing. So yes it can prioritize the game traffic over video streaming or backups.......but the bigger question would be WHY a person would do that knowing it could impact the game.

I suspect you can load a normal network driver and it will work just as good.

The problem with these "special" programs is they defeat most the standard troubleshooting methods. I would normally say ping the gateway and see if you get loss. They could be prioritizing ICMP and somehow blocking http by accident. NSLOOPUP is always a good command to test the DNS but some of these programs it will work from linemode but not from within applications.

I would also get a copy of malwarebytes (free version) and scan your machine. Many time you can get toolbars in the browsers that causes all kinds of headaches.

:p  I know the whole thing seems like a crock to me. Do you think I should get rid of it? I still have the CD with it on it.

I'm sorry but I'm very much at sea with some of the more technical stuff you posted.

I know that DNS means Domain Name System, but how could I control these intermittent issues on such a big network (College Dorm)? (Even if I had a more standard network program)

What do you mean by 'ping the gateway"

I looked up NSLOOPUP, and while I don't know how the utility works the site i looked at said that it would get confused or include incorrect data. It suggested that I try dig or host, but I don't know what they are or how to use them. Do you agree that these would be viable programs/utilities to use and if so how do I use them and to what end am I using them?

Thank you for your advice, both of you, I really appreciate it.

had a typo its nslookup.

Its worth a try to remove it. It very easy to fix it does not work at all problems. Ones where some things work and other do not gets very messy to figure out.

DNS is only a guess it could be that software or it could be virus checkers or it could be firewall either on your machine or that the college has. Best is when you can compare a machine that works at the same time yours does not to see what is different.

What of the host or dig commands, what do they do and can I use them to figure anything out?

This is for a different mobo but still the killer nic. See if it helps you any: https://forum-en.msi.com/index.php?topic=169838.msg1240...

I also found this: "Just to feed back I followed the advice to fully disable the Network Manager software and disable the Qualcomm Atheros Killer service and the NIC has been 100% since. Of course it just like a normal NIC now (without some features i.e. WOL). But at least it works!"
In this MSI thread: https://forum-en.msi.com/index.php?topic=170617.msg1248...

Good luck!
