[Solved] Internet speed problems

Hello. I noticed that my firefox is taking a long time "looking up" sites, even google, so that sites that have to do multiple lookups load extremely slowly. In windows it works fine. I thought it was a dns problem so i tried using opendns 208.67.222.222 in resolv.conf but no change. I am using networkmanager but a tried wicd and had the same problem. I searched around and other users had success with making some changes to resolv.conf or hosts but I don't see what else I can change.
Here is my setup:
rc.conf
LOCALE="en_US.UTF-8"
HARDWARECLOCK="localtime"
TIMEZONE="America/Port_of_Spain"
KEYMAP="us"
CONSOLEFONT=
CONSOLEMAP=
USECOLOR="yes"

DAEMONS=(syslog-ng !network netfs crond alsa hal networkmanager samba)
hosts
# /etc/hosts: static lookup table for host names

# End of file

modprobe
# /etc/modprobe.d/modprobe.conf (for v2.6 kernels)

alias ipv6 off
Any help is appreciated.

Okay, I made an error when testing the nsswitch configuration. According to its man page nsswitch.conf is loaded by a process only once. The process will continue to use this configuration even if the file is changed.
Initially I had "hosts: files wins dns". Using "hosts: files dns wins" seems to have solved the problem. I had to make sure to restart my browser when testing the changes.
Thanks for all the help.

Hi, I have internet speed problem.
When I connect to internet from my PC - speed is more than 90 Mbps, but when I use my router - about 45 Mbps.
What the problem?

Are there any other devices connected to the router? Any new devices you did not have connected to your Linksys/Cisco router? Are you running the default configuration on the router? Check the computer if you are running Windows update on the back ground. If it is running then try to disable it temporarily. Here is the link for how to disable it: http://www.techtalkz.com/windows-7/515869-windows-update-enable-disable-automatic-updates-windows-7-...
As far as wireless is concern try the following settings:
# Open up the browser and on the address bar type 192.168.1.1 that will open up the Gateway setup page.
# Make the Channel Width to 20MHz only and select the Channel to 1, 3, 6, 9, 11..
#Adjust the following advanced wireless settings:
~~ Lower the beacon interval from 100 to 75
~~ Lower the fragmentation threshold from 2346 to 2306
~~ Lower the RTS threshold from 2347 to 2307
Then check the connectivity status.

Internet Speed Problem

{edited for privacy}. Because the internet speed in the restorant is so slow, we called the verizon support center but it took us more than 1 hr to get a contact and we still have failed have contact with them. If anyone from Verizon company is reading this, please hear our voice mail that we left. We are usually free around 3 pm, please call us. Thank You.

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

    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?

E3200 internet speed problem

I've just replace my router from WRT320 to E3200, because I've upgrade my internet speed from 100M to 300M.
But the speed test just show about 90M when using E3200, but if I plug direct without using E3200, the speed is up to 280M. For the firmware, I've tried 1.0.01, 1.0.02 and 1.0.03 aswell. Did anyone got a solution on that?

If you can change the Ethernet cable through which you are connecting the computer.. As well as update the drivers of the LAN card. For updating the drivers of the LAN card follow the steps:
# Click on Start --> on the search box type "devmgmt.msc" and click Ok...
# Device manager window will appear and in that check for the Wired adapter.. Right-click on the name of the Adapter that you want to install and click Update Driver Software…
# A window will appear asking “How do you want to search for the driver software?".. Click “Automatic Update"..
# It will automatically update find the latest drivers and will update it...
Check the computer if you are running Windows update on the back ground. If it is running then try to disable it temporarily. Here is the link for how to disable it: http://www.techtalkz.com/windows-7/515869-windows-update-enable-disable-automatic-updates-windows-7-...

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.

Internet speed reduced by airport extreme

I have an older AE, the dome. I use it to create a wireless network for my Apple TV an laptop but I have my G5 desktop connected to the AE with an ethernet cable. After noticing internet speed problems I checked it with speakeasy and sure enough it was only 2 megs down. It should be about 8. When I connected the ethernet directly to the G5 intstead of going through the AE my speed jumped up to 8.5. I thought that since the G5 was connected with an ethernet from the AE it would not suffer from wireless speed restrictions. Am I wrong?

I get great connection and speed with AirPort Extreme, it would be the last thing I would suspect.
have you tried the usual reboot modem and router?
Are you set up as a home network WPA2? (This keeps the neighbors from piggybacking on your network)
How much improvement do you get via Ethernet?
I suggest asking Charter if they have provisioned your line correctly for the speed you are paying for (would not be the first time a provider didn't deliver correct speeds)
Is it possible the modem is done for? How old is it?

Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting?

Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting on the computer, and how?

One possibility is that you may need to "Upgrade" your Cable /DSL Modem if you have an older unit. ISP's that provide your Internet service in recent years have been switching over from DOCSIS 2.1 version Modems to DOCSIS 3.0 version Modems, which handle the new higher data streaming speeds the ISP's are offering. I would suggest you call your ISP's Technical Support and inquire about this possibility.

Bought 4th Gen 3TB TC - streaming TV over the internet is now so slow and now is constantly buffering. It seems the Airport Utility is always 'searching for new networks' - don't know if this is the problem. It's not the internet speed as checked that.

Bought 4th Gen 3TB TC - streaming TV over the internet is now so slow and now is constantly buffering. It seems the Airport Utility is always 'searching for new networks' - don't know if this is the problem. It's not the internet speed as checked that. I took my old router upstairs and was streaming TV via my ipad seamlessly - the same program via the TC was constantly buffering.
I just expected to be able to plug in the TC, so a simple set-up and experience wireless both upstairs and downstairs in my house. For some reason the range is low and speed veru disappointing.
I am far from being an IT expert but I would welcome advice about setting up this TC so we can enjoy the product as it was designed. Please HELP!

No silver bullet........but my suggestions may drive you in the right direction.
1. Unplug the power cable from the TC and wait 10-15 minutes before powering back up.   Seriously wait!
      Proceed to #2 if this dosen't help.
2. Unplug the power cable from the TC, ubplug the power cable from your Broadband Modem (assuming it's a cable modem), disconnect ethernet, and cable from modem.
2a. Wait 10-15 minutes then re-connect cable, ethernet, and power back to modem (your modem should power up unless you have a power switch) wait for all the modem lights to come on EXCEPT activity.
2b. Connect ethernet from modem to TC, and plug in the power cable to TC.
      Proceed to #3 if this dosen't help.
3. Reconfigure the TC.........Read here........http://support.apple.com/kb/HT3728
All really simple to do....if you need additional help let me (us) know.

K9N2 Sli Platinum + SSD OCZ Vertex 3 = Slow Speed Problem [PARTIALLY SOLVED]

Hey folks,
I have a problem with my new SSD. I only get sequential reads of 140MB/s and writes of 114MB/s.
I think it is a driver related issue. I once got faster SATA2-like speeds but cannot reproduce the system settings again... Everything back to SATA1-like speeds after reboot.
First my pc specs:
MSI K9N2 Sli Platinum, BIOS v3.9
- 6 SATAII ports by nForce 750a SLI
- 2 ESATA (External-SATA) ports (back panel) by JMB363
- Supports storage and data transfers at up to 3 Gb/s
AMD Phenom II 965 Black
Patriot PV224G8500ELKB Viper II Series DDR2 4GB (2 x 2GB, CL5 PC-8500/1066MHz)
SSD SATAIII OCZ Vertex 3, 120GB, FW v2.11
LG Internal BlueRay BH10LS30
Windows 7 Ultimate x64
I only get very slow speeds with the SSD. I tried so many things that I am getting very frustrated now, I am even thinking about getting a new board and ram just to get the SSD up to speed...
1)
I installed Win7 first with all the default settings in Windows Setup from DVD. Default "IDE ATA/ATAPI controllers" driver was "Standard AHCI1.0 Serial ATA Controller".
SSD was connected to SATA1-port, On-Chip Sata Controller AHCI enabled in BIOS, Extra RAID/IDE Controller disabled.
All fine, but whichever benchmark I used (AS SSD, HD Tune Pro, Atto Disk Benchmark, CrystalDiskMark; other tools used: DriveControllerInfo, AIDA64/Everest, CrystalDiskInfo ) I got e.g. 140MB/s Read and 114MB/s Write sequentially (CrystalDiskmark, similar with random data AND only zeros ).
Trim working (it seems) with AHCI driver. I also changed to nvstor64 driver (nforce driver setup 15.56), with is marginally faster but not what you would expect from a SATAIII drive on SATAII controller.
2)
I installed Win7 using "diskpart" (Shift-F10) during disk setup, setting a cluster size of 64k instead of default. No real change.
3)
After reinstall of Win7 x64 (again...), I changed from SATA1 port to SATA6 port, also enabled Extra Raid/IDE controller set to AHCI as well.
Nothing changed. With all settings to default in Windows (ahci default driver), I then manually updated the ahci to nvstore64 driver in Device Management, rebooted.
Then a minute later after reboot I got the following Sequential speeds with CrystalDiskMark:
273MB/s read and 137MB/s write (random data) + 274MB/s read and 220MB/s write (with zeros) !!!
While I ran this benchmark Windows came up with a message: "You must restart your computer to apply these changes - Restart Now/Restart Later".
After the previos reboot, when I changed manually from AHCI to NVSTORE, I had changed nothing in the current session, apart from running CrystalDiskMark.
I did reboot and I was back to the slow SSD speeds again = 140/114 MB/s...
4)
I have tried every possible combination of mainboard SATA ports, drivers changing with nvidia setup/manually, deleting and disabling controllers (incl BSOD and startup repair :D ), chaning bios settings around, but I just cannot get back the faster speeds
There is never any change in speed, whether I use ahci or nvstore64, whichever benchmark I use, whether random or zeros...
5)
Could the SSD be broken, something internally preventing it from faster speeds (with this one random exception)?
Could it be that my K9N2 SataPorts only allows for / reduced to SATA1 speeds?
Am I missing something with the driver setup?
Do I need additional drivers for the extra JMicron Controller when using SataPorts 5/6 ?
I have no other mainboard to test this with...
Please guys, I am going to jump out of the window if I can't fix it... :(
Thanks, Mike

Hey guys - problem 'solved':
I tested the OCZ SSD Vertex 3 120GB with following sata3 controller card http://www.lycom.com.tw/PE-115H.htm.
The card itself works immediately (needs at least PCIe x4 slot, will work slower otherwise but still faster than the OCZ SSD @sata1 with nvidia chipset).
There is some raid setup, doesn't apply to me, the boot even with the card is really only a few seconds longer and not annoying at all. Windows (7 x64) needed a driver, supplied on CD (which is cheap and making noise like h**l). The card works w/o the driver but doesn't harm to install it...
Also, just to clarify, this sata controller card did not need any specific setup at all. Just put it in, plug in sata cable (I use akasa sata3-rated), maybe change boot device in BIOS (I didn't even have to), done - booting Windows as usual.
Benchmark CDM with sata controller card Lycom PE-115H:

http://img850.imageshack.us/img850/7549/cdmpe115hahcirand.png
Speed is much better than before with nvidia chipset 750a SLI controller: sata1 (sata2 whenever it randomly worked):

http://img13.imageshack.us/img13/6258/cdmahci0x0sata6contnv64.png
Final thoughts:
Well, I am happy with the SSD speed now (PCIe limited to 5Gbps). However, I had to spent quite some time to get it working on my sata2-cabable mainboard. Finally, I had to buy a extra controller card to get it working reliably at speeds faster than sata1. There is hardly any useful information on why this problem occurs with (older) nvidia chipsets and OCZ (sata3) SSDs. I still think that OCZ must know about this problem, but regards this issue as low priority, while at the same time not planning on giving up on sales to people with nvidia chipsets. Maybe OCZ should just make a big sticker on the box the drives come in with something like "Does/Might not work with nvidia chipsets, please use third-party sata controller card or different SSD manufacturer". But then none of these potential customers would buy OCZ SSDs...
I will keep the sata3 controller, anyway handy to have, but return the OCZ Vertex 3 120GB and replace it with a SSD from a different manufacturer (Corsair Force GT, Patriot and OWC are not that great to get around here). The benchmarks for most people will not achieve the maximum advertised OCZ speeds anyway, so why not go with a brand that allows for some plug'n'play with some customer support.
Hope this post helps others like me with their nvidia chipset + sata1 speed problem
Cheers, Mike

Erratic Internet Speed Causing Connection Problems

Hi BTCare,
I have been a BT Broadband Customer for many years and haven't faced any difficulties up until a week ago; I have the original white home hub. In June 2010 an ADSL upgrade was carried out in my area and since that time I have been able to achieve 10mb Broadband speed consistently (Peak & Non-Peak) without any problems.
In the past 5-7 days my Internet Speed has been slowly deteriorating and is now becoming almost un-usable. Earlier in the week the speed dropped to around 5mb and I contacted BT Support over the phone and they instructed me to run speed tests throughout the day suggesting that the problem may lie with internet activity in my area increasing during peak times. This didn't seem to be the case as the speed tests were returning similar speeds regardless of what time of day I carried out the tests.
Since then my speeds have continued to decline to as low as 1mb at times which has now made it difficult to even use the internet as even loading web pages sometimes takes up to 30 seconds. Some wireless devices (e.g. iPhone) can't even establish a connection to the router even when I am standing directly in front of it.
I have configured my wireless connection (changing channels etc.); re-starting the router at intervals hoping this will improve matters but this has proved fruitless. I have run a speed test now with the results as follows:
Download speedachieved during the test was - 240 Kbps
For your connection, the acceptable range of speedsis 100-500 Kbps.
Additional Information:
Your DSL Connection Rate :5923 Kbps(DOWN-STREAM), 1191 Kbps(UP-STREAM)
IP Profile for your line is - 500 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 8.84:23.63:67.79 (SBE:NBEBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.
The results of this test will vary depending on the way your ISP has decided to use these traffic classes.
Upload speed achieved during the test was - 171 Kbps
Additional Information:
Upstream Rate IP profile on your line is - 1191 Kbps
Any support you can provide will be greatly appreciated.
Kind Regards,
Dan

Internet speeds keep slowing down to a crawl

I'm having a problem that has only developed in the past week which was during a time when I haven't changed any configurations in that period of time since my son was born a week ago yesterday and I obviously had more important things to do than mess with my network configurations. However, about 2 weeks prior to his birth, in the process of configuring a baby monitoring system with icam source, 3 weeks or so ago, I read that I might be able to improve my internet performance, I ran googles namebench a couple of times and added and re-ordered the DNS servers that had been listed prior to any problems developing based on its' reports. My internet speeds improved as a result of changing those DNS settings and stayed good until the past week. But of course, we now need to use the computer as part of our baby monitoring system and it's not working worth a **** and I'm getting frustrated since I can't put my finger on the problem and I don't really have time to spin around in circles right now. I'm sure it's probably something simple and I can't put my finger on it though. Sleep deprivation is new to me.......
I've kept running log of notes so this is a little deshoveled but I figured the more information I provide the better the chance someone might help me get this solved quickly.
In the last week, since my sons birth, my internet speeds would be okay after restarts and resetting everything, 2.5 Mbps or so but after a 10-15 minutes it starts to slow down to .2-.3 Mbps. I went thru all my network settings, restarted everything, repaired permissions, I've changed ethernet cables reset PRAM, firewall is running, stealth mode enabled, allow signed software incoming connections and my various other programs such as netsessionmac4f3c6b, skype, java, itunes, etc.
All sharing services off and pretty basic login items at startup including growl.
I had AT&T come out and check my DSL line and everything checked out on their end up to and out of the DSL modem based in their equipment tests.
The problem seems to start when I connect my imac (a fairly loaded 27" imac I got in Dec.) First off, as soon as the imac is connected to the modem via ethernet, the old ethernet modem flashes and continues to flash, even right after startup. So the tech thought something was running in the background and I can't figure out what. I looked through login items but don't see anything that would be a problem and am afraid to eliminate everything.
So I created a guest account to eliminate any login items (I think) and in I got 5.69 Mbps right off the bat. But after a minute or two, without changing anything my download speed slows down and I get for example .77 Mbps. The same thing happens with my administrator account on the imac. Fast speeds at startup and more importantly if I change the configuration by switching between ethernet and airport, I get fast speeds right after changing the configuration but after a minute or two I am well below 1.0 Mbps. I've got several network configurations with automatic, airport and ethernet set up in different ways including a clean ethernet connection with the original DNS settings.
I haven't set up an airport only account but that really isn't the way I want to hook up the computer that sits right next to the modem and runs my network. Restarting the old modem and direct connecting the computer to the modem results in the same thing happening.
I connected my ethernet from the (old?) modem directly to my ancient powerbook G4 and I got +5.6 Mbps download but it also slowed down to 300 kbps after 5 minutes or so the first time (old modem?)
Now to explain why I have "old?" listed above. I was then able to get a new DSL modem from AT&T, hook it up just fine, get enormously faster internet service in the 5,000 kbps only to have it slow back down to around 300 kpbs after connected for several minutes.
directly connected to imac-bypassing router
3,500 kbps
after 15 minutes-250 kbps
connected to imac thru router/time capsule with airport extreme
2500 kbps
after 15 minutes=166 kbps
directly connected to an older powerbook G4 with new modem
IP address of 192.168.1.64
5.65 Mbps on speedtest
after 15 minutes=5.67 Mbps
after 30 minutes= 5.59 Mbps
1 hour-5.66 Mbps
Very solid, stable readings for what I am used to. This would seem to isolate the problem to the imac.
directly connected to imac with new modem
IP address of 192.168.1.64
5.8 Mbps on speedtest
after 30 minutes= .60 Mbps-ping takes 250 ms
1 hour= .46 Mbps-ping takes 250 ms
Now a problem that only started last night after I hooked up the new modem and started up my old Time capsule/airport configuration, I got a message that said something to effect of "another device on this network is using computer IP address 192.168.1.64. So I tried manually changing last digit of the IP address on the computer to one number higher and it kept saying the start and end range were incorrect so I shut the airport station down since when it was connected, it would not allow the computer to connect thru the router via ethernet. I did a hard reset on the airport and I got it back up and running just fine but the internet speeds on the imacs' ethernet connections are so slow it's practically worthless. I also checked to see what was connected to my airport on any given occasion, 2 iphones, 2 pads, another imac running upstairs and a newer powerbook running icam source that is supposed to be the baby monitor. Except for the laptop everything can use "802.11n" but the powerbook only connects via 802.11g so I have set the airport to that limiting setting.
Any suggestions? Is there a way for me to log what is happening so I can report in more detail?

First thing is to check if the wireless is on a sensible channel: HomeHub doesn't always make sensible choices. Install inSSIDer on your laptop and see what other devices there are around and if there is any clash. Also, try moving the HomeHub around a little, even quite small differences can make a big difference to wireless signals.
You could run an ethernet cable from downstairs to upstairs. Easy to do, but can be a bit unsightly. If most of your devices are upstairs, you could use this cable to connect the modem to the HomeHub. If you have devices both up and down, you may want to keep the HomeHub downstairs and add a switch upstairs.
HomePlug may be suitable for you. If you search Amazon for HomePlug you will see a couple of kits for just over £30. Don't go for an 85Mbps one. A 200Mbps such as the TP-link or D-Link should be much better than wireless, but not as good as a cable.
Depending excatly how many devices you want to connect and where, you can pay more and have a builtin wireless at one end: http://www.amazon.co.uk/Devolo-1408-Wireless-N-HomePlug-Adapter/dp/B00472MMCQ/ref=sr_1_15?ie=UTF8&qi... Or it may be best for you to use the basic devices and add an old wireless router in switch mode.

Verizon is Capping Internet Speed/Service for "Unlimited" Customers

Some recent news has been brought to my attention by Verizon Wireless' customer service department, and I think that given the severity of Verizon Wireless’ continued breach of contract to Internet customers, this matter should be brought to everyone else's attention as well.
I originally purchased a Verizon Wireless USB Internet Card in 2007. I was offered a plan that entitled me to an “Unlimited Internet Usage Allowance”. I kept the same wireless Internet device for two years and never acquired any issues or concerns. On January 20th, 2010, I went into a Verizon store and was offered a free upgrade to the new MiFi Mobile HotSpot. I was told that I could test the product for 30 days to make sure that it worked to my standards and my Internet needs. It worked perfectly. I used it for multiple computers in my home, as well as work and travel.
My problem with the Verizon MiFi began on October 21st, 2010 when my Internet suddenly became extremely slow and unable to access any web pages without minutes of waiting. I continued to call customer service and go into the Verizon stores throughout the month in hopes that someone could find a ‘glitch’ and solve my issue of what soon became No Internet access. I did all this with patience and good faith, as I have continued to pay $60 a month for “High speed 3G” service. Two weeks ago, I took the MiFi device into the store and requested a new device since it became entirely defective. My new device arrived in the mail and I have still spent the last week going through the ring-around circus of Tech support and the only logic they can come up with is, "Either the device is defective or my computer is too old." This is not the case, as I recently purchased a new laptop.
What I discovered was that Verizon neglected to inform me for the past two months that I had gone over my "undisclosed usage threshold" (Even though I pay for Unlimited Allowance) and now my internet speed has been capped and I am unable to access the Internet. I spent 4 hours on the phone yesterday and weaved my way into a small department called "AIT" which is supposedly a new sub-contracted company that is suppose to help negotiate my "situation". They of course are closed, and my numerous voice mails will most likely never be returned.
At this point, I am still paying for something that does not work, and Verizon has taken it upon themselves to decide "how often" I can use the internet. This was not disclosed to me in my contract that I signed in Jan 2010, when I continued my Wireless plan for "unlimited usage allowance."
I want everyone to be aware of this, before they head out this holiday season and spend hundreds of dollars on a Verizon Wireless Internet Device, and eventually will have to deal with the same nonsense I'm currently going through right now!

I started with one of the few unlimited plans back in 2008- They kept telling me to "hang on to it- cause it won't be around for long!" So I did and when I upgraded my device- everything worked great for 7 months. I started using it more frequently as a hot spot for more than one computer, we're talking email, web browsing and paying bills- Not Xbox360 for 24 hours a day or fownloading 10 videos a day!? I don't even know how to do that!?!
And the first month we went over- we got capped! Now it runs at about a quarter of the speed. Which was never disclosed to me. And to think- they market this MiFi 2200 as a hotspot for up to 5 computers??? I can only imagine how quickly people are being capped.

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.
