Windows 7 64 Bit Very VERY slow internet speed

I just bought two new laptops for my wife and I and we've been having terrible trouble with download speeds since taking them out the box.
We are using the exact same configuration and IP as before only our last two computers were on XP and Vista but there were no issues whatsoever. I even went and bought a new router just in case that was the problem but it made absolutely no difference, leaving
me with the conclusion its a problem with the 64 bit version of Windows 7.
Currently I cannot even watch a Youtube video because after loading the first couple of seconds, it stops loading and then after a couple of minutes there's a quick burst of speed and stops again.
I can't complete a speed test on my connection on either laptop. Normally this would take only a few seconds but the site (speedtest.net) crashes every time using windows 7.
Setup;
Windows 7 64Bit
Intel i3 2310M @ 2.1Ghz
4Gb of RAM
My IP is VirginMedia UK on a 10Mb connection (same problem wired or wireless)
As you can imagine this is very frustrating since I have just paid out over £1000 to find my browsing experience has virtually at a stand still.
Any help in this matter would be very much appreciated

I recently had the same problem after installing Windows 7 64bit. The internet speed for some reason was really slow. After looking for a solution I tried to flush the DNS. It worked.
Open start menu
type "cmd" in the search then hit enter key
when the new screen opens type:
ipconfig /release
hit enter and then type
ipconfig /flushdns
hit enter and then type
ipconfig /renew
hit enter and the problem is solved.

Slow internet speed - terrible service

For the last 5 weeks I have been plagued with very slow internet speed. I have spent at least 4 hours on the phone with verizon techs. They always say that they will call back and never do. This is absolutely the worst service imaginable.

Step one: Visit http://www.giganews.com/line_info.html and post up the Traceroute the page shows, if you wish. Be aware that your non-bogan public IP Address will show up. It might shown up as the final hop (bottom-most line of the trace) might contain a hop with your IP address in it. Either remove that line or show only the first two octets. What I'm looking for is a line that mentions "ERX" in it's name towards the end. If for some reason the trace does not complete (two lines full of Stars), keep the trace route intact.
For example this what I saw when I was using Verizon
news.giganews.com
    traceroute to 71.242.*.* (71.242.*.*), 30 hops max, 60 byte packets
    1 gw1-g-vlan201.dca.giganews.com (216.196.98.4) 13 ms 13 ms 13 ms
    2 ash-bb1-link.telia.net (213.248.70.241) 39 ms 7 ms 7 ms
    3 TenGigE0-2-0-0.GW1.IAD8.ALTER.NET (63.125.125.41) 4 ms 4 ms GigabitEthernet2-0-0.GW8.IAD8.ALTER.NET (63.65.76.189) 4 ms
    4 so-7-1-0-0.PHIL-CORE-RTR1.verizon-gni.net (130.81.20.137) 6 ms 6 ms 6 ms
    5 P3-0-0.PHIL-DSL-RTR11.verizon-gni.net (130.81.13.170) 6 ms 6 ms 6 ms
    6 static-71-242-*-*.phlapa.east.verizon.net (71.242.*.*) 32 ms 32 ms 33 ms
Step two: Can you provide the Transceiver Statistics from your modem?
#3 If you don't know how to get that info:
a) What is the brand and model of your modem?
b) If you have a RJ-45 WAN port router connected to it: What is the brand and model of the RJ-45 WAN port router?
#4 If you have a RJ-45 WAN port router connected to the modem, even if you know how to get the Transceiver Statistics from the modem: What is the brand and model of the RJ-45 WAN port router?

Slow internet speed, being used by unknown websites

Hello all,
For about a month i have been experiencing slower internet speeds than usual. Contacted the isp and went through all the processes and there was not a problem at their end. I was advised to go to network utility and check how many processes there were, found out that there was too many to count.
It seems i have internet processes coming from my macbook ip address from uknown sources such as ookla.com etc. Now i have downloaded spyware programs for mac which have failed to find any viruses or spyware at all.
Now i know the problem is coming from my macbook as the unwanted guests our appearing under the macbook ip address, my router is receiving the right speed so it can't be the isp?
Right now i am just wondering what to do to stop these processes using up my internet connection and potentially turning my router into a server.
Any help would be grateful.
Mark Lees

Yeah i have little snitch but it appears to not spot these websites, i can send you a screenie of the netstat screen
Then that would imply the only connections going out from your mac are from legitimate applications.
lots of things will engage outbound connections.
safari
firefox
itunes
spotify
and sites that you visit that have embedded video often host the video on other servers. So you would be suprised at how many socket connections you have at anyone time.
If you have little snitch look at the monitor window and it will show all the recent connections.
You could reset little snitch to default rules and then you will be prompted to allow or deny each new connection.

Slow internet speeds and dropping connection

hello, I am making this post on behalf of my dad, for a good few months (5-6 maybe even longer) we have been experiencing slow internet speeds and a dropping connection when ever the phone is picked up. when an incoming call is answered some or all devices connected to the internet drop out for a second then come back online, the connection does not completly disapear but causes any voice chat, streaming or gaming to disconect. We have BT wireless phones (not sure what exact type) which we have had for a few years. they are connected through an ADSL filter which as far i can remember has been there for years. We have a netgear DG834GT router which has also been there for a few years. I went onto its settings and got this information, not sure if its usefull or not.

Slow internet speed -upgraded it to highest speed

I have had FiOS internet for about four years and never questioned the speed 10/2, but I had it plugged into the router. On 3/4, I upgraded to TV FiOS/internet and phone bundle. I do not have my computer where the router is located now (downstairs) and I had asked them to move it upstairs, but left before they had done it. When I checked the speed (I guess the wireless speed since it is not plugged in to the router), it was 15.66/10 mbps. I ordered the 35/35 mbps speed bundle. I called Verizon and asked them about it and she checked the speed and said that it was "pretty good" considering it is wireless. What? I am not getting what I am paying for. Do I need a DSL filter on all the phone lines? Do I need a new router (I still have the old one)? I have read on the community here that everyone has called several times to get an answer to the slow internet speed problem. Does anyone have the 35/35 mbps speed plan and have it work at this speed? I might as well go down to the 15 or 25 plan if that speed is all I am every going to get......But maybe if I go down to 25 plan, I'll get 10 or 15...... I will continue to try and work with Verizon to get this solved. .Thanks for any help.

Win 7 on bootcamp partition, very slow internet speed

hi!
it might be an answer to my problem somewhere on this forum, but
right now i do not have the time to browse through - so ill just post my problem quick and simple.
im running windows 7 ultimate on a intel imac, via bootcamp. the issue is simple, yet pretty annoying.
in iOS, my internet speed is great, as it should be (my bandwidth is 12/12 mbit).
but in windows 7, for some reason (been like this ever since install) things are going SO slow.
i mean, watching videos on youtube is a nightmare, every 3 second at lowest quality possible, it still
has to buffer. same goes for other streaming sites/services. downloading usually does not exceed 300 kb/ps, but in
ios this could easily hit 1,5 mb/ps.
if i listen to music on say grooveshark (adjusted to lowest quality) the music stops to buffer if i load a different webpage. its that bad.
ive taken a bandwidth check in windows and in iOS, and in iOS the speed is normal, in windows its 1/10th of what it should be.
anyone know why this problem persists?
as i know of, windows 7 doesnt have any bandwidth limiting of default.
so i thought it might be a windows 7/imac hardware conflict. help?

Hi, I'm having the same problem.
I installed win8.1(64bit) on a iMac7,1 20inch(mid 2007) using Winclone.
Everything was working fine after I downloaded some driverhelper and installed those drivers.
Yet the internet on Win8.1 is very slow, the download speed is merely 60-100kb/s .
While if I open the Mac system, the same resource can easily to beyong 2MB/s.
As I have 25Mb/10Mb connection at home.
I'm new here , don't know exactly what driver I need to fix this problem.
Try to install boot camp.
However, I tried 5.0 / 4.0 , it all said bootcamp x64 is not supported on this computer model.
Don't know where i can download the bootcampe 3.0 to have a try ?
Or is it just too old iMac to be fixed？

VERY slow Internet speeds

During about the past week my internet speeds have been VERY slow, sometimes loading a 1 minute youtube video has taken upto 5 minutes, and i also have been disconnecting off the internet very frequently. We have had bt internet for about 3 years and this has never happened before. We have a BT home hub and all our computers connect to the internet wirelessly. I have spoken to a friend and he said he had the same problem this week, he said he phoned up and got sent a new hub. I am not sure if this is the problem but all advice is appreciated. Thanks in advance. I live in dundee (Scotland) if its any help.

Geoff,
I think Angus has either a Home Hub 1.0 or 1.5 as the front screen when you access the router settings page show "My Broadband Connection" and lists the speed and all the other pieces of information on this screen. Would I be right Angus?
In terms of the slow speed issue you are facing. Please can you post the information on the Home hub screen under "My Broadband Connection" so we can see the results.
Also, the general troubleshooting steps for slow speed would involved moving the Home Hub, if not already there, to the Master/Test socket.
Pleas see the following link for information on how to do this:
http://bt.custhelp.com/app/answers/detail/a_id/13892/c/346,4740,4740
You may also want to run a speed test, as Geoff suggested ecm200 did, via http://speedtester.bt.com, as the results from this test can be used by technical support to raise a fault.
I know that some people think that because they have been connected to the same socket for a certain period of time, and the connection/speed has never changed, that the socket must be Ok, but if this socket is an extension socket, the internal wiring may have degraded over time and this is the cause of the poor speed. This is why technical support always ask to go to the Master/Test socket, to prove that the fault is on the BT Network.
I reckon, at worst, you will get an engineer to visit, who will either fix the fault, or recommend that the Hub is replaced. However, the troubleshooting steps will have to be completed before you get to this stage.

Very slow Internet speeds throughout most of the d...

For the past month my Internet has been deteriorating. I get patches of the day (maybe 30minutes) where I have a normal Internet speed, latency's of ~30 and download speeds of around 5k kbps. But now my average download speed is more around 300-600 kbs with latency's greater than 150. I find that the connection is slightly better late at night or early in the morning. I have tried the call centre's but they really haven't helped what so ever.
Here is my router status:

And here is a speed test i just did showing 1157 kbs but this is again due to the fact that I am doing it late (00:30) and that has been the highest it has been in days:
Download speedachieved during the test was - 1157 Kbps
For your connection, the acceptable range of speeds is 600-7150 Kbps.
Additional Information:

IP Profile for your line is - 5000 Kbps
Would be grateful for some help/insight in this matter as it very fustrating.

Hi jpleclef,
Your line is entitled to get the speed close to 7 megs. The test that you have uploaded shows the good router status. I would advice you to check it with the ethernet cable (yellow ended). If however it gives you the same speed then it can be considered as an issue.
There might be some flag on the line.
Could you please tell me your plan.
And there are several ways where you can raise this issue to higher level.
Dear jpleclef, Please note that you need to be paitient with this. I am saying this because I've seen thousands issue like this which customer endup giving the BB connection, even this doesn't help because changing the service provider doesn't changes the line.
So, Task for you is:
Check with ethernet cables.
tell me your option plan
In the next post I'll explain you a lot more of the test result that you have posted. Feel free to write me on *******.
Regards,

Slow Internet Speed after Leopard

I'm having a funny problem since the installation of Leopard and that is very slow internet browsing speed. But its not as simple as it sounds. I have another Windows PC on the same network; when its on mac internet speed is slow, when Windows PC is off the Mac internet speed if fast and normal.
I'm not alone in this problem. I read similar problems on Apple Gazette after installing Leopard. Any suggestions?

http://discussions.apple.com/message.jspa?messageID=6039643#6039643
Had to search for it. I'm having the same problem as you see by my post in this forum. I hope this works for me. I also happen to be in South Carolina. Small world.

Slow internet speed because of RWIN and MTU

I've got a problem with cable modem "DHCP" speed the default internet settings for arch are very slow for me on a 2mb connection, I get 1700kbps max where as on other distros and windows i'm getting 1960+kbps the issue is RWIN size and MTU size.
With the default settings my RWIN is "128960" when it should be set to "51100" for my speed, also MTU is 576 which is very low (dialup MTU speed I think) for a cable modem which should be "1500".
I've tried setting my RWIN size in /etc/sysctl.conf like this in arch:
# Tweaks for faster broadband...
net.core.rmem_default = 51100
net.core.rmem_max = 51100
net.core.wmem_default = 51100
net.core.wmem_max = 51100
net.ipv4.tcp_wmem = 51100 51100 51100
net.ipv4.tcp_rmem = 51100 51100 51100
net.ipv4.tcp_mem = 51100 51100 51100
net.ipv4.tcp_rfc1337 = 1
net.ipv4.ip_no_pmtu_disc = 0
net.ipv4.tcp_sack = 1
net.ipv4.tcp_fack = 1
net.ipv4.tcp_window_scaling = 0
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_ecn = 0
net.ipv4.route.flush = 1
With extra tweaks for window scaling 0, timestamps 0 etc.. and done "sudo sysctrl -p" to set it.
But after retesting my settings at dslreports.com I get a very low RWIN like "9654" for some reason, does anyone know how to permanently set it to "51100" ?
I also have a problem with settings MTU I done "sudo ifconfig eth0 mtu 1500" that works fine but gets reset on reboot, I've looked though this thread http://ubuntuforums.org/showthread.php?t=82093 and it needs to be set in "/etc/network/interfaces" but I have no such directory.
So anyone know how to Permanently RWIN MTU for a DHCP network in arch?
EDIT: I've managed to set MTU to 1500 on boot now speeds are up to 1958kbps, now just wondering about RWIN

You probably want tcp_window_scaling = 1, not 0.
Window scaling is used to let you have a bigger window size. The only reason to turn it off is if you are behind a router that distorts your TCP packets and causes connection issues. There is such a router between my school and the internet, and so I have my network script shut off tcp_window_scaling when connecting to the wireless at school. But I keep it on elsewhere.
Try turning it on and giving it a go.

Slow Internet Speed C50-30

I recently purchased a Lenovo C50-30 Desktop and my internet speed is very slow. I have my old computer next to it and it runs just fine on the internet (Using wireless connection). Any ideas on how to increase the internet speed for the Lenovo? Thanks

Please answer as many of the following questions as you can. You may already have answered some of them; in that case, there's no need to repeat the answers.
Restart the router and the broadband device, if they're separate. Any change?
Run Software Update and install all available updates for OS X or the computer's firmware. Any change?
Are you connected to Ethernet as well as Wi-Fi? If so, disconnect the Ethernet cable or adapter and test.
If possible, connect to the router with an Ethernet cable and turn off Wi-Fi. Any difference?
Are any other devices on the network, and if so, are they the same?
If you can connect to more than one network, are they all the same?
Are all network applications affected, or only some? If only some, which ones?
Is networking always the same, or is the problem intermittent?
Disconnect all other devices from the network. Any change?
Start up in safe mode and test. Any difference?
Start up in Recovery mode. From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. Any difference?
If possible, turn off Bluetooth and disconnect any USB 3 devices. Any difference?

Slow internet speeds on iMac running 10.10.3

Hey folks,
Hoping you can help me!
I have a late 2012 21.5" iMac running 10.10.3 and currently I've been getting very slow internet.
I've done some troubleshooting:
I've taken it to the Genius Bar and the airport card is fine.
I've reset dhcp lease which used to work but now no longer does.
Currently, my internet only gets normal speeds (about 100 Mbps down) when I delete my system config folder. Even after deleting it, however, it's only fine for a short period of time (usually a few hours) before it goes back to crawling speeds (usually the speed test ping test fails).
It's definitely not the hardware of the machine because it's picking up the wifi, it's not the router because the speeds are fine on my other devices and fine when I delete the system config folder, so I know it's software related. The issue does persist in a guest user or known good account so I know it's not user repeated.
I wanted to see if anyone else has any ideas to resolve the issue in the OS' current state prior to me just doing an erase and install.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Slow internet speed on 1 of my computers.

I have 3 computers in my home. My Fios Router is downstairs in the office of the house. There is another computer upstairs on the other side of the house. This computer is used for gaming mostly. My wireless connection barely reaches this computer and I am stuck with VERY slow speeds. I might as well be on a dial-up modem! Verizon said I had to move the router for it to work. The only way to get all 3 computers to have access to the wireless would be to have the router in the middle of the living room which is not an option.
My question is what would best help the upstairs computer to have acceptable internet speeds? The computer I have was custom built by a friend. I was considering buying a D-Link DAP-1522 802.11b/g/n Xtreme N 2.4/5GHz Selectable Dual Band Wireless Gigabit Bridge/Access point. Will this help?

Use either a MoCa link as suggested above, or better yet just use Ethernet. I wouldn't bother with Wireless, as much as a different router (N-based) might improve the experience.

Slow internet speed on Mac, but not on iPad

So, I've just tested my internet speed on my Mac and I got very low results. I also ran the test on my iPad and got the full and regular speed. I noticed that indeed the internet is faster on my iPad. This wasn't happening at all, not that I can remember. Is my Mac's network card damaged or something?

Please answer as many of the following questions as you can.
Restart your router and your broadband device, if they're separate. Any change?
If you can connect to more than one network, are they all slow?
Are all network applications slow, or only some? If only some, which ones?
Is networking always slow, or only sometimes?
Disconnect all other devices from the network. Any change?
Boot in safe mode and test. Any difference?
