Question Ethernet connection dropping out

[sammz]

Hi all, I've recently been having issues where my internet is disconnecting on my PC. An ethernet cable is connected to my PC, and my wifi is working fine. At first, my PC wouldn't connect to wifi, but that's fixed (though it doesn't seem to let me do anything but watch stuff, wifi won't let me use Steam or online games).
Either way. From troubleshooting the connection, I found this problem is detected "The default gateway is not available". The troubleshooter fixes the problem and it's working fine. It happened again a few hours later, I ran the troubleshooting and it's fixed. Any ideas what's going on and how to stop this?

Other side effects of this have included a complete PC freeze and stuttering, though these occurrences have only happened once.

I have tested another cable, and this seems to work, however, I've not long-term tested this to see if the internet disconnects as well, I require a longer cable to do this, if anyone also has any ideas why my Wifi only let me browse the internet, and watch videos, but not play games I'd appreciate that too.

Not sure why wifi would be that different than ethernet. It does have much more data loss but that mostly affects playing online games not so much downloading.

I would avoid having both the wifi and the ethernet active at the same time. Windows is suppose to be smart and always use the ethernet if both are active but sometime it does not work. You can actually change the metics on the interfaces to prefer wifi so I think windows might just get confused at times.

Key on ethernet is avoid fake cables. Those flat cables tend to be the most common. You only need cat5e but it much be pure copper with wire size 22-24. If you can't find that info buy the cable from another vendor.

Simple test for both ethernet and wifi is to leave a constant ping run to the router IP. This will show you how much loss and latency spikes. Ethernet tends to have a constant ping of 1ms with almost no spike. Wifi can also be fairly low but will have random spikes.

In both cases packet loss is bad and extremely rare on ethernet
