Fast PC and network, slow internet.

[videobear]

Fast PC and network, slow internet.

System: Asrock X99 Extreme 4 MB, Bios 3.6, 5930K CPU, O/C to 3.9 GHz. Samsung EVO 850 SSD C: drive, 4 WD Black 3TB in RAID 0. Nvidia GeForce 970. Windows 10 64 bit. Kaspersky antivirus.

Network: Gigabit ethernet, Cat 6 cables throughout. Verizon FIOS Gateway gigabit router, Netgear GB switches.

The network reports everything is working at 1Gb/sec, from the PC adapter to the router. The PC reports it's running at 3.9 GHz, no temp problems. Other computers on the network have no problems. Network diagnostics detect no problems. sfc /scannow detects no problems. Windows memory diagnostic shows no problems. Speedtest.net shows I am getting 50 Mb/sec or better upload and download.

And yet web pages are slow to load and I'm getting a lot of "connection reset" errors. I tried disabling the Kaspersky firewall, and even all antivirus services...made no difference. I usually use Google Chrome, and tried Edge and Firefox...no difference.

I looked for unneeded services and disabled them. No effect. I found another thread that seemed to address this problem and tried the various solutions suggested there, but I did not have most of the apps identified as culprits (e.g., AMD Quick Stream). I tried removing GeForce Experience...no effect.

I also tried changing the settings in the Intel network adapter driver to force 1GB link, rather than auto-negotiate. No difference either way.

Running out of ideas here!

What is your DNS settings like? What ISP package do you have? 50Mb/s is OK, but not stellar.

 

[Adrian Ocampo]

Im guessing you have done this but have you tried to re-install your Network Drivers?

 

[Rhinofart]

Op stated that his connection speeds are OK, but browsing around sucks. That leads me to believe that Name Resolution (DNS) isn't working well at all.

The likely cause, if two routers are used, plus any firewall software.

is a mix of the hardware firewall of the router, the security level set, and the options chosen.
try setting both the Hw firewall of the router to a medium setting for security.
And also the software one.

Also double check windows security center settings of windows.

It really does look like the slow speeds are a clash between multiple SW fire walls running at the same time and also a Hw firewall of your router.

Open a command prompt.

type "nslookup www.google.com"
It should report back an IP address almost isntantly.
Type "ping (IP address from frist step)"
What is the response time, should be bellow 100ms

If step 1 or step 2 is really slow then type "tracert (IP address from step 1)"
Paste the result

Thanks, Adrian. Yes, I reinstalled the network adapter drivers. Didn't help though!

From Network and Sharing Center on your PC, go into adapter settings and dissable IPv6
From the configuraiton page of your router, set the DNS to 8.8.8.8 and secondary of 8.8.4.4, these are google's DNS servers and they are faster (and more reliable) then ISPs ones are typically.

 

[boosted1g]

Also, have you tried testing the speed of a network file share from a wired computer to a wired computer?
Should be able to get 80+ MBps trasnfer speed, depending on hard drive speed

 

[videobear]

Thanks, Boosted.

I haven't disabled iVp6 yet, but I already tried the Google public DNS servers earlier...in fact, I normally use them. No effect.

The issue is definitely with my computer. I hooked a different computer up to the same ethernet cable/router port, and it worked fine. File sharing on the local network is at about 130 MBps.

I am going to wipe the drives and reinstall everything.

 

[boosted1g]

Ok so the problem is going out over internet because 130 MBps is the FULL gigabit speed.

Before you go as far as wiping your whole computer, open command prompt as administrator and try these 2 things:
Reset TCP/IP Stack:
netsh winsock reset catalog
netsh int ipv4 reset reset.log

Flush DNS
ipconfig /flushdns

 

[Rhinofart]

Disable your IPv6 as your DNS is trying to go to it first, and has to go through the timeout period.

 

[videobear]

Thank you everyone! I found the problem...unfortunately, not before I'd wiped the machine and reinstalled everything fresh.

It turned out to be a setting in the network adapter. I have the Intel 1218-V chip, found on many motherboards. I was using a driver dated 2015, and one of the power saving settings, "Energy Efficient Ethernet" was drastically slowing my web performance. If you are seeing a similar problem, first go to Intel's site and download the latest driver. If that does not solve the problem, look at the driver settings and disable Energy Efficient Ethernet.
