Confirmed high speed Internet but low speed access

Windows Central Question

Pay for Time Warner/Spectrum's ultra high speed broadband (300Mbps/100Mbps).
Tech was here a few days ago and confirmed those speeds are being delivered.

However my LAN wired desktop is delivering a fraction of that speed (15/5).

Have run all the troubleshooting I've read about (Win10 Network troubleshooter, SFC, DISM) - all report no issues.

Regularly run CCleaner - have cleared caches.

Similar difficulties with current versions of MS Edge, Firefox, and Chrome.

Android devices attached to the same network do not have speed issues.

Cable guy suggested RAM could be a problem but asking The Google contradicted that theory.

I work from home and rely on fast web access for my livelihood. Ready to pull out my hair.

System specs:
PC: Compaq CQ2014 (wiped clean with Win10 install about a month ago)
OS: Win10 Home v 1607 (Build 14393.479) 64-bit

Hi did you bother to read post #18.:wink: And also all the other replies in this thread.

Sure, post#18 talks about how the motherboard doesn't have expansion slots and speedtest server locations.

80% of the other posts are about upgrading the RAM.

His PC has a 100mbps ethernet port, so he should still be able to top out at around 80-90mbps on speed test sites. I am not sure how that is relevant or contradictory to what I suggested.

Hi friend! I think we are all aware that the OP's ethernet port should support 100mbps. However it doesn't seem to. No one is contradicting your reply.
Team work is a good thing! Thanks for helping. I'm tired and I'm going to bed. :grin:
PS It's always a good thing to have the latest driver for your adapter. I agree with you 100%. The W10 upgrade is a killer on this and getting the latest driver from the manufacture is a great suggestion!
Thanks for helping!

Unless you're running out of RAM, upgrading your RAM will have no difference on your internet speed tests. 15/5 is too low, even my 11 year old laptop with centrino and 1Gb RAM can max out my 100mbps link.

One thing I couldn't believe no one suggested till now was updating the Ethernet controller driver.

1. Download the latest Ethernet driver from the manufacturer's website and update it
2. See if you can borrow a USB to Ethernet adapter and try using that instead
3. If possible, attach another laptop/computer to your LAN and try transferring data between the 2 both ways and note what speeds you get.

Someone above said that you cannot get good speeds with on-board ethernet ports. That is simply not true; as all on-board ethernet ports have their own controllers. My NUC has an on-board gig port and I can reach 700-800mbps transfer speeds on my LAN, no problem.

slyronit is right, could be driver related. Worth a try to check if OP has the latest driver installed. 15/5 is really too low, he should have 6x that downlink and double for uplink.

Do not remember someone saying on this thread that with onboard ethernet you can't get full speed, but you are right, It's not true.

Actually, during the original troubleshooting, I did check drivers.

The Ethernet card is a Qualcomm Atheros AR8152 PCI-E Fast Ethernet Controller (NDIS 6.30).
Device Manager says the driver is current: v 2.1.0.16 (04/01/2013).

If memory serves, Qualcomm does not provide direct consumer support; all drivers come from PC OEMs.
Likewise, the HP Support Assistant reports all drivers up-to-date.

I'm not sure the purpose of a USB/Ethernet adapter.
Does this permit the installation/upgrading of an Ethernet card via the USB when it would be otherwise unavailable? Doesn't having to go through the USB bus controllers involve its own speed degradation? Would this be a viable means for me to bypass my motherboard bound 10/100 Ethernet card with a 10/100/1000 gigabit card? (If I can believe The Google, I'm certainly willing to invest $15 - $35 for an adapter, if it can break the 100 Mbps threshold).

Meanwhile, there are some general slow system issues, so the Crucial 8GB upgrade kit (on a brown truck for delivery today) should offer some ancillary improvements this afternoon.

Finally, just to add another monkey to the wrench, today's speed reports:
Speedtest.net: 92.14/23.92 Mbps
Time-Warner: 9.83/2.37 Mbps

Seriously, WTF?
(And I double checked, this isn't a unit mismatch, they both report Mbps)

Seems about right, confirming my thoughts.

USB ethernet adapter is a possible solution but be aware of what speeds their are capable of. Most of them max out at 95 Mbps. However there seem to be some to be able to achieve up to 300Mbps on a USB 2.0 port.

So let me get this straight, your PC is actually able to hit 95mbps on speedtest.net? Where is the problem then?

I suggest borrowing a USB ethernet adapter for troubleshooting.

Again, none of the buses (USB/PCI) are that slow to not support 100M, at least.

@Plexus ...

Any theory as to why the Speedtest.net and Time-Warner tests differ by a power of 10?

Given the relative affordability, I went ahead and ordered an ANKER (AK-A7522012) 3-Port USB 3.0 HUB with 10/100/1000 Gigabit Ethernet Converter. I realize it is designed for USB 3.0, but the AMZ Q & A reports it is backwards compatible with USB 2.0 still providing 1 Gbps.

So, RAM upgrade tomorrow (sorry lost track of time) ... Ethernet workaround by Wednesday.

As always, I'll report back to the group.

The problem is that Speedtest.net says 95 Mbps, but Time-Warner says 9.1 Mbps.
Meanwhile, I still have lagging page loads and perpetual loading indicators.

If you're getting 95mbps on speedtest.net, the problem is unlikely to be the ethernet adapter.

What DNS server do you use? Are you using a 3rd party DNS server by any chance?

You'll have to translate DNS server for me.
I connect via the TWC supplied Arris Interactive 1706A directly to their cable and directly from the router to my desktop via LAN cable.

The tech connected directly to the router and via my LAN cable and got 300 Mbps both times.

Can you explain how/why Speedtest.net reports speeds 10x faster than Time-Warner's speed test?

Well, there seems to be a problem with Time Warner Cable DNS.

I recommend changing them to google's public DNS or openDNS. Here is how to: How to Switch to OpenDNS or Google DNS to Speed Up Web Browsing

Don't you agree slyronit?

@ PlexusCR

Seriously?
TWC sent out a tech. He connected his diagnostic magic box directly to my modem/router and to the LAN cable I use and showed me 300 Mbps results.
But he couldn't see a DNS conflict on his own network?
Is this a temporary thing, e.g. network traffic, or an intermittent problem, e.g. loose cable on the pole, bad switch at HQ?

Tried the GoogleDNS.
ipconfig confirmed their servers in use.
Again I got 10x speed difference between speedtest.net and Time-Warner.

There seems to be a slightly faster first appearance of webpages, but the in progress spinner still takes 30+ seconds for full page load

Chrome is my default. Prior to changing the DNS, I had the same issues with Firefox and Edge.
All are current versions.

After the DNS change, curiously, Edge seems to be the speediest. Not talking instant page loads but a good 75% faster than Chrome or Firefox.

Let's try disabling TCP MTU path discovery to see if that makes a difference

Open regedit as admin,

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters
\EnablePMTUDiscovery

PMTU Discovery: 0

Check the speeds again. Once done, set it back to 1.

And what if the registry doesn't have a PTMUDiscovery entry?

What's the concern with Chrome and 3 GB of RAM?
Are we back to a system resource issue?
This is something the 8 GB upgrade could resolve?
