Wired internet randomly disconnecting

My friend and I built my PC and were extremely cautious with the components. (We just built his about two weeks ago and everything is working perfectly) We installed the correct software, did a test boot, etc. General PC building precautions and preparations.

My specifications are as follows:
- Intel i5-3570k
- EVGA 660ti FTW+
- Corsair Vengeance DDR3 1600Mhz (2x4GB)
- ASrock Z77 Extreme 4-M
- Seasonic M12 II Bronze Modular 750W PSU
- 2 TB 7200 RPM Hitachi HDD, Blu-Ray Optical Drive, Corsair SP120 fans, etc.
- Corsair 350D case & Windows 7 Home Premium 64-bit

- I don't have a wifi card so I use a broadband ethernet connection. I also own a very high quality Zoom router/modem combo that is $150+. All of the other devices; smartphones, tablets, game consoles, etc. work fine and never randomly disconnect + have full bar connections, so I assume the problem is with the PC. I have used multiple different new ethernet cables as well as a cross over cable and the internet continued disconnecting every so often. As I type this, I was Skyping with my friend and a yellow triangle exclamation icon at the bottom right of my taskbar appeared on the internet icon which seems to look like a computer monitor with a cable on the left for the image. To fix this, I have to unplug the ethernet from the router, wait a few seconds, and then plug it back in. Sometimes I have to do this procedure multiple times and even unplug it from my computer and the router to get the internet to work again. I have consulted multiple computer technicians and one of them updated my entire system when it came to software such as motherboard drivers, graphics card drivers, etc. The connection is good when I play games. My ping is generally below 80, my games on steam still won't download faster than 700kb/s, but the major problem is my internet randomly disconnecting. Sometimes Youtube videos will load extremely slow, my ping will shoot up in game, and my Skype call will drop to 2/5 bars.
I also used the same hard drive that I used in my old AMD computer, but now I have intel and Nvidia. I switched chipstets, but did a clean install of the OS. At first I had some conflicting drivers, but I uninstalled everything AMD, cleaned my registry and all of my apps using ccleaner. Games run flawlessly and my system works fine with the exception of it not turning on if it is off for more than a few minutes as well as the internet sometimes randomly disconnecting and having very slow download speeds and high ping on some occasions.

Any ideas what would cause this?

A couple of things occur to me. First, you're obviously proud of your modem/router but Zoom is not a major OEM and I doubt that device is on your ISP's approved list. FWIW, I paid more than $150 for each of my modem and router. In fact the last time I upgraded my own modem & router it was to fix the same problem you're having. It didn't work. The problem turned out to be a bad connector on the coaxial cable coming into my house...
What i would do is run your system without skype running at all for the day and see if the problem persists.

skype has turned into a pile of crap compared to earlier clients that eats your bandwidth and causes all sorts of problems even when its just idling and just keeping your contacts updated.

one thing that does help is to disable its use of port 80 as it does help reduce its update frequency and its bandwith usage.

on my own connection before i did this, whenever my brother used skype to chat with friends youtube just stops working properly, as soon as skype is disabled everything works fine again.

at the end of the day skype has just become malware essentially.

I have cable. My old laptop and desktop both ran just fine on the internet, they ran quickly and never randomly disconnected. I've called cable one multiple times, and it's surely not the router. The ISPs just get lost and keep giving me other numbers to call, which those solutions never work.

The problem turned out to be a bad connector on the coaxial cable coming into my house. Of course, in my case I was losing connection to all devices. If the problem really is inside the new computer it almost certainly is the MB. I read this board daily and IMHO AZrock has reliability problems. Another thing. It's a bad idea re-using an HDD. If your old computer was more than 3 years old you're on borrowed time. I don't know what your finances are like so I'll tell you what I would do because I can afford it. I would replace the MB with an ASUS and get an 128GB (min) SSD for my boot drive. I prefer Samsung or Crucial. You can use the old HDD for bulk storage like music & movies. Actually, I hope the other responders' solution about Skype works for you. I don't know much about Skype. Good luck.

Surprisingly, Zoom was actually on my ISP's approved list. I was beginning to assume that the problem was coming from my motherboard because I had actually received most of these components for my birthday, but my family just couldn't afford higher-end parts so I couldn't get a new hard drive, and had to downgrade on the motherboard. The hard drive should be fine, I took it out of my hp desktop which was only a few months old and did a clean install into my new computer. I wiped the drive completely in order not to have any driver issues. But I have also read other forums as well saying how crappy ASrock's realtek drivers are, so I may have to eventually just get a new motherboard as well as an SSD. I have another problem that I think is linked to my motherboard, because I'm sure it's not any other component.

I appreciate your advice greatly, and here's a link to my power problem

Read that if you'd like, I think this problem also has to deal with the motherboard

Hey, i got the same problem i have a Cisco router with Linksys.
I think that Cisco and Linksys has this problem, I've seen, "Randomly disconnects me from the internet when playing a game" ,on other post With The
Same Setup or vary close to the same setup
try another router it might work
OR i could be the firewall like "Karsparsky"
here's a link to that:
