Tracking Down Slow Ethernet


New Member
I've been running W8.1 - 64 bit on an Asus m3a78 motherboard for about 10 years with no problems. AMD processor. Up until now, my ISP provided me with "up to" 100 Mb - no problems there. I now have an "up to" 500 Mb fiber service. The wired speed tests all read around 80-90 Mb up and down, day or night. I can take my Apple laptop, remove the connection from my desktop and wire directly to the laptop. Speed test 450 Mb or above. Stumped! Everything works fine, no hangups or unexplained quirks, just tests slow.
Pertinent Information: I have tried to lock down the telemetry settings by turning off unneeded services, updates, user experiences...anything that phones home.
Some of the tests I have done:

-try a dedicated gigabit Network card - no change
-flush dns - no change
-reset Winsock - no change
-tweak "properties" on the network card - nothing
-check Process Express for suspicious programs - nothing obvious
-check for virus and spyware - haven't found anything
-check for hard disk constantly operating - nope
-I use the firewall in my router, not Windows Firewall
-no antivirus
-use Proton VPN normally (but turn it off for the speed tests)

It was my impression that doing a 1 Gb ethernet connection is pretty basic for any computer and does not require a super high speed chipset. There is always the person who thinks new drivers will fix anything, but this motherboard hasn't had an updated driver or bios for years. But, I haven't installed any new equipment or made setup changes to the motherboard. And it was supposed to do 1Gig when it was new. Like I said, everything works fine, but I can't get a 500 Mb connection to speed up past 80 Mb. Maybe the aging of components is showing up. If I get a new motherboard, I will have to get W10 and start from scratch.
Thank you!

What can I say? Just what we think of as a simple process, 'Getting on the Internet' , is a real bucket of worms, electronically speaking. There are millions of bytes of code, flying around in thousands of circuits, and regardless of how much RAM we have, or how big and how fast the HD is, we still have only ONE CPU. It's unfortunate, but alas, that's the way that IBM designed the PC. And the first CPU's were only 16 bit. Thank Goodness, today we have either 32 or 64 bit CPU's.
And no matter how fast and powerful your CPU is, it's shackled to the system clock.

AMD came up the idea once used on the Commodore 64 cpu, to use both sides of the clock cycle to do work, and not just the Rise of Clock, which was common in computers of all sizes.

Having said all that.... there are still so many things involved in getting what you might want to consider Good Internet Speed, there is no one Quick Fix.

I live out in the country, and my best available internet connection is Hughes Net, satellite internet.
If I intend to download a movie, or a new OS, I will turn off my Satellite Modem for a few minutes, and when I turn it back on, I'll have the fastest connection to the internet that I'll have all day.
The longer that the modem is ON, the slower the internet connection.

AVG put out a program called "PC Tune Up". One of its features was to optimize 77 points in the registry, concerning the Internet Connection. I'm sure there has to be another program, out there somewhere, that can do the same thing, but, I've never found it.
Then there is a Speedup program for Firefox, called "Speedy Fox". That optimizes connection parameters for Firefox. I use both of the above mentioned programs.

I'm sorry, that I don't have a Quick Fix for you, but, I'm not sure there really is one.
Good Luck, Mate!
