How many network cards are showing in device manager ?
I agree with Rusty about device manager.
Make sure you only have one network connection in the machine.
After you have removed them from device manager reboot.
Make sure you have the onboard network card driver.
After reboot
  1. Right click on the Start button then choose Search.
  2. In the search bar, type cmd. ...
  3. Type netsh winsock reset into the Command Prompt window and press Enter on the keyboard to run the command.
  4. A message will appear saying to restart the computer to complete the reset.
 
Hello. Sorry for the delay in returning to the matter.

So just to recap, I received a new modem from Comcast and installed it. At the same time I performed a network reset on the problematic PC.

I have definitely seen an improvement in download speed, upload speed was never affected. I seem to be able to see, using one particular testing site, a sustained 450 - 500 Mbps as opposed to the 112 Mbps previously. Another speed test service reports around half or less of that speed which is odd as they both carried the same results in previous testing. With additional testing on other services it seems to be that I can average around 300 Mbps which is obviously a major improvement over the 112 that they ALL would report prior.

The ethernet connection was never a problem and is still fine.

The new modem is exactly the same as the previous model and is still their latest offering.

Now clearly the machine is still not seeing the speeds that other devices are getting (700+) when tested from the same location and the co-located PC still outperforms it by a good 100-200 Mbps.

So although I can't say the case is closed the situation is better than it was by a country mile and I can realize some of that performance I pay for and need.

I am very much open to further suggestions and I am happy to try anything else but from this point on I don't know what else to do and part of me feels I'll just have to live with it.

I thank everyone for their time and effort. A BIG thank you guys!!

The best way I have found to test the speed is to download a file and compare it form the same site and compare it to other system on the network.

Most of the test sites will show speed if testing on single or multi connections.

I will be out for a couple of days and will check on this when back @PeterOz.
 
Hi Rustys,

I agree with that and in fact I discovered the problem originally through that very process. I was finding that I was getting terribly slow downloads of work related files on the affected PC but not so when using the other one.

As far as deleting the other network adapters from device manager does that mean all those listed as WAN Miniport?
thanks,

No - What I see should be the on board adapter.
Did you reset the winsock - Post #45 ?

Also you mentioned before about a plugging in another wireless point.
What about Ethernet over power ? Click On Me
