I have my HTPC running Windows 8.1 and it is connected over hard-line to my router/cable modem (Netgear C3700) and I cannot keep a solid network connection. I have tried different cables and ports.

The symptoms of this problem are, but are not limited to, the following:

  • Speed tests via speedtest.net vary greatly. They either report just fine, Time Out, or report very slow speeds (reporting 1.5 Mbps when it should have at least 25Mbps)
    XBMC Metadata Scraping is very slow.
    Team Viewer keeps popping up that it lost connection to the server
    Internet browsing in general is fairly slow

These are not issues that persist over WiFi. I have port-forwarded and allowed a certain program through my firewall(s) (a program which I will not name in this forum).

I know that Windows 8 had some crippling network issues but I was pretty sure they'd been fixed in 8.1.

I'm hoping this isn't a NIC issue but we'll see.

Here is my System Info via dxdiag:

Out of 4, 3 timed out and the one that made it was 64ms
and no, transfer speeds are slower than hell

Sorry for the tardiness of my response.



I'm hard-lined via ethernet into my Cable Modem\Router Combo Netgear C3700 (with Comcast Xfinity *sigh*)

My adapter is my built-in ethernet on my mobo an Asus M5A97 R2.0 which worked fine before hard-lined into the router I was renting from Comcast. It also worked great hooked into a Netgear N600 when I was on Wide Open West (WOW) cable internet at my old house.
