my internet download speed slow although I have subscribed to 800mbps internet plan.

Hi all,
Recently my internet connection  has been upgraded by provider from 100mbs to 800mbps snd they have confirmed I must have the speed near to 800mbps, but what comes to my surprise was the connection never had that much of speed, the fastest I have ever reached only up to 200mbps and never cross this.
So I decided to call the technician to inspect internet  line and etc, they did not found out any wrong and when the guys do some test with his own laptop he managed to get > 800mbps  that speed.
my questions is that what I can do now in order o improves my speed ? at least  500mbps if possible although I have been provided with 800mbps.

I'm running my machine with windows 10, 64 bits with 16GB memory installed and this pc has connection to corporate networks via vpn which I rare use them except when needed.of course I have antivirus installed and I never have any intention to run tsi machine without protection.

Make sure the computer has a network card capable of going that fast. Upgrade the network card driver (reinstall if no new one).

Restart and connect the computer by Ethernet directly to the ISP Modem.

Make sure VPN is not running.

Run and see what speed you get.
You will get much less speed over VPN. Are you going through any sort of router or firewall? If you are, that is probably the bottleneck.

Of course, you need to be on a gigabit or faster wired connection.

Are you going through any sort of router  

Routers need very high throughput to manage the high speed. That is why I suggested connecting the computer directly to the modem to test.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

How are you getting these stats on your speeds? Are you using a website like Speedtest? Aside from the information that the others have asked, you have to remember that there are two points for these speeds to be affected, your location and the destination you are pulling data from. If you are testing only one server on a speedtest or destination there is a chance that the data is also being throttled by the destination if they cannot support the bandwidth by a multitude of reasons. Basically, if your using 800mbs to download something from someone with dial-up, your going to be slow.

The above suggestions are important and where I would start, but to add to these already mentioned by other members, consider where you are downloading from. Try multiple destinations and speedtests etc. Find an average to make sure its not the other end that would be the biggest factor in your issues.
Just recapping what people have said - you've probably heard that old saying, "a chain is only as strong as its weakest link" - this applies here, except it's more like "internet speed is only as fast as its slowest link."

Downloading something is very much like a chain. Your computer is connected to a router that is connected to a modem that is connected to your ISP's main connection. Then the ISP's main connection connects to a bunch of other network connections that eventually lead to the server your computer is trying to talk to. Then that server has to send data back through the same chain.

When you upgrade your internet connection, it isn't going to make everything go faster because there are lots of servers out there that might not be able to go faster than a certain speed, so even if your connection is CAPABLE of receiving data at 800 Mbps, if the other server can only send it at 100 Mbps, then 100 Mbps will be the limit when you talk to that particular server.

Another way of thinking about it is a car that is CAPABLE of going 800 miles per hour, but you are limited to whatever the speed limit happens to be on a particular route you take.

A major service like Netflix will generally have the speed capacity to match yours, which means you're CAPABLE of using all 800 Mbps, as long as the network pieces between you and Netflix are also capable of that. So if any of those pieces aren't capable of it, then you're not going to get the 800 Mbps.  Some common examples:

- If you're using a wireless connection to your router, then you probably aren't going to hit the 800 Mbps (except maybe in short bursts).
- If ANY of the connected pieces uses an old, standard CAT 5 cable that is only capable of 100 Mbps speed, then that's what you'll be limited to.
- If you have a really long network cable (e.g. over 50 meters or over 100 meters), then that can degrade the speed (depending on what kind of cable it is).
- If your router is only capable of a certain speed (e.g. it has 100Mbps ports), then that's what you'll be limited to.
- If you have other people in your home that are using the connection at the same time (or maybe have a neighbor stealing your connection wirelessly), then they're going to take some of that 800 Mbps capacity when they're using it.
- If you're testing using some kind of connection that requires a ton of DNS lookups (e.g. P2P of any kind), that can limit the overall speed.

So ultimately, all YOU can do is ensure that every piece of your own home network is capable of 1 Gbps (usually network speed capacities go from 100 Mbps straight to 1 Gbps), and is properly secured, and that you're downloading from something capable of those kinds of speeds.

Hi motioneye,
I don't have a solution for you, but I want to make you aware of a very interesting thread (current and active) here at Experts Exchange that is discussing the same issue, i.e., slow Internet speed even though you're subscribed to high speed:

I haven't posted in that thread, but have been following it with great interest. There may be some ideas/tips in there that are helpful for you. Regards, Joe
Question is: how do you measure this, do you just download a file? You should use the same tests the technicians used - did you?
Of course you also need to assure you test under the same conditions as the technicians - if they used an ethernet cable, you need to use ethernet as well (with a gigabit cable [cat5e, cat6 or cat7]) and not use WLAN, as your WLAN might not be able to offer the high speed in a stable way.

I just did a test with both my Avast VPN turned on, as well as with it turned off and got very similar results at

Windows 10 Pro
NBN Internet

The VPN connection was a little slower, but only by a couple of megabytes in both upload and download tests.

This doesn't answer your question, but I post in the event you might find the info helpful.

Regards, Andrew
Most routers and firewalls cannot run anywhere close to gigabit speed, even if they have gigabit interfaces. The ones that do typically are enterprise products, not consumer or SMB products. That is why you need to test with your device directly connected to your ISP, without any other gear (other than potentially a gigabit switch) in between.

What is the use case for such a fast connection? You won't stream any faster, though I suppose that it would slightly decrease latency.

Hi all,
When the technician came here,  he used same cable and connection as mine except his laptop running lightweight application without having antivirus, vpn and installed with windows 7.
The point here is when he did the test he got > 800mbps to the same speedtest link, using a cable that I used and  whereas mine only 200mbps
So you don't have the same application to test with? That's bad.
Did the technician leave you the name of his test application? Can you find it out?
If not: did the technician do any other real life tests like downloads from a domain that you remember, that you can reproduce? Remember: downloading is only then a good speed test if we know that the source of the download is able to provide the files at full speed. You can only be sure that it is if you have someone else do the test who reaches the expected full speed over at his place.

So you know it is the computer (and not the modem or router) causing the issue.

Maybe consider backing up, reinstalling Windows and then start testing computer speed from just operating system and then gradual build up of software.
"to the same speedtest link" - hm, I had missed that, sorry.
I'd start with a new network card driver as those often have bugs that have a negative impact on performance.
Also tell us a little about your hard drive - is it mechanical or SSD? Mechanical ones often benchmark lower than 800 Mb/s (while 200 Mb/s seems still too low, even for an old mechanical drive). Anyway: do a benchmark of your hard drive and share the results, since you need a fast drive to store the temporary downloads at the speed they come in.

Hi ,
I have good SSD drive and I dont think the drive has play any important part here simply because that technician has only windows 7 and normal hard drive but can easily achieve 800mbps
"I dont think the drive has play any important part here" - they do, rest assured. Anyway, you have an SSD so let's say, that is ruled out, too. now move on and do the NIC driver update.
JohnBusiness Consultant (Owner)Commented:
The NIC was one of the first suggestions here. Please let us know if you tried that

As already mentioned the disk speed may be an issue. If not then try to boot from a USB linux distribution and test a download to your harddrive. If it is any faster than it's probably  your OS (clutter) /Drivers and not your hardware.

I second the opinion that it's probably either your NIC or it's software-related, and the simplest way to eliminate the NIC is dfke's suggestion of using a "LiveCD" Linux distribution, which is basically just booting Linux from a CD or USB thumb drive (you don't actually install it on your PC at all - it boots and runs completely from the CD or USB thumb drive). You can download one and put it on a thumb drive in about 10-15 minutes, boot it up, open the default browser and run the same speedtest.

If it's still 200, and you're using the exact same cable and connection as the technician, then it's almost certainly a limitation of your computer's network card (NIC).

However, if it's around 800, then it's probably software/OS related. In that case, I'd start by updating the drivers for your network card if any new ones exist. While it's POSSIBLE that it could be related to the more "complex" TCP configuration, it's not quite as likely. If you're unsure, you can always use a tool like the TCP Optimizer:

Alternatively, the network adapter drivers within Windows can have different modules running. For example, you can turn off IPv6 for one specific network connection. Some antivirus solutions will try to protect you by analyze all traffic, and they do that by hooking themselves into the network adapter as a module, or by running as a "virtual" network adapter. Either way, that kind of thing can bottleneck speeds, so that's something else you could check for.

But your first step should really be the Linux "LiveCD" step to rule out the hardware. Because if it's hardware, then it doesn't matter what you do in Windows.
I say first step is to confirm speed test without a router or firewall being used. OP has not stated whether or not a router or hardware firewall is in use during the testing. I have seen SOHO hardware firewalls be the bottleneck on 50 mbps connections.

So your doing in relation to what? The technician. You would have to reproduce what the technician was doing, that is exactly what he or she was doing on your laptop, and then start from that point. Where did the technician plug into?

Hi all,
Today I did another test, a simple test by comparing speed on  difference browser, I'm stunt that edge gave me  660 mbps no matter how many times I had run speed test,   chrome  somehow very obvious with less than 200mbps despite  the internet says they are no #1 and  my typical browser slimjet still around 200-250mbps.
What do  you guys think over here ? what make chrome and slimjet slower than edge ?

I never do any changes with configurations, it just today I feel want to do test with edge ...
Never heard that before, but I must confess, I don't have such a fast connection to try and reproduce it with ;-)
JohnBusiness Consultant (Owner)Commented:
Edge is integrated directly into Windows 10 so it is very fast.

Other browsers slower point to an OS issue.  So live with Edge (good browser) or as I suggested earlier, start fresh with your OS and build it up until you know where the slowness is.

Have you done the same speed test on another machine and verified that both have the same results?

Hi John Crawford
Yes I had tried with surface 3, via wifi connection I still have  good connection with edge, somehow around 192mbps speedtest while chrome only 10mbps
JohnBusiness Consultant (Owner)Commented:
Thanks for the update and I was happy to help you.
What would you do to solve it, reinstall? The assumption "edge is fast because it's integrated" is just a funny one since this is not about rendering or even html. It is just plain downloading and has nothing to do with browser technology. There will be a reason, yes, but it will not be browser technology. The guys over at google have fast connections, believe me, and they would know if their browser was so far behind in downloading.
