Hello, I have recently purchased a Gigabit modem with service. I had to buy a gigabit usb to ethernet adapter/dongle to achieve more than 100mbps because my network card on my laptop would not support gigabit speeds. In addition to buying the dongle I also purchased CAT6 cable for it. I am plugged directly into the modem without a router or switch and my speeds that I get when performing a test on the ISPs speedtest are in the 300-450 mbps range while on speedtest.net site I get 200 - 400 mbps range. I performed a wget command test in Cygwin with thinkbroadband.com at 1GB file and I get 4MBps.

Cables are good modem tested good, signal strength is great, im at full duplex, and I also ran the tests in safemode with networking for the same results. The USB is USB 3.0 which my laptop does have.

When the ISP Tech came out he tested the connection with his laptop and he got around 840 Mbps.
Is the ISP throttling my connection to my pc?
what hardware issues would impact my speed?

Update 12/19/2015

Tried doing another speedtest after getting home from work. I am getting now 333 Mbps on all test sites. Called and talked to a Tech I from my ISP, tried different scenarios this time, like restarted the modem, switching IP addresses and DNS. None of these worked.
It seems to me that I am being capped.. For what reason I don't know. I find it strange that 333 is persistent without fluctuation on ALL sites.

Any help would be great, thanks.

@kanewolf, here all some specs of the laptop.

Inspiron 15 (3521) (i15RV-6145BLK)
at a glance...

Display: 15.6 HD (720p) WLED with Truelife (1366x768)

Memory (RAM): 6GB, DDR3, 2 DIMM, 1600MHz

It says it supports usb 3.0. Could it be a 3.0 running slower than it should be?

Yes, I have plugged the adapter into all of my USB ports and I get the same result.

It is because when I do plug it into my Internal NIC I only download at 100mbps.

Ok I was able to get it to 580 Mbps by turning on the setting under the Gigabit USB 3.0 ethernet adapter by switching under Speed and Duplex from Auto Negotiate to 1.0 Gigabits per second Full Duplex. Still, not in the 75% range of what I am paying for. But an Improvement. I'll continue to see what the other settings will do.

Have you tried transferring a file across a gigabit network to confirm the USB3.0 adapter can actually perform as it claims?

Ok I found the solution to the problem. For anyone else who may be experiencing this issue. I ended up spending needless amounts of money on this issue when I actually didn't need to.
The actual problem was an option in msconfig. The option box was checked for number of processors.
9


So now I am able to get within the 75% range.
two months of trying to figure this out bought an ssd drive and more memory for my laptop :(
Hope this helps someone.
