Hello,

I do not really know where to post this. The other day my internet suddenly became slow but my computer is not. I have a HP G60 Laptop with Windows 7, 3GB of RAM, 2.93 GB total physical memory, and 1.63 Available physical memory. I have difficulty with the speed of websites loading. What used to take just seconds now takes 20-30 seconds or more. Videos on youtube takes a very long time to load and skip. The only thing I can think of that happened recently was I connected a video camera to my laptap and received a BSOD. I rebooted and never saw the screen after that but I now I have this problem. I have cleaned out my temporary internet files, deleted large files, and checked for viruses with Malwarebytes, and super anti spyware receiving no results. I do not know where to go from here. Thank you for any help you can give me!

Yes I also tried system restore. At the time it did not do anything. Right now it appears to be working much better. I'm not having problems with any videos like I had yesterday. Could this be a problem with the modem? The entire time I was connected with 5 full bars and it was slow. What does power cycling the modem and router mean? At this point I don't think I need to do what rockmilk advised because things seem to be much better. Do you have any other tips as to why this could have happened and how to prevent it?

Do you have a password set up on your router or can anyone freely access it?If you do not then I suggest that you set a password for it.

Also, presuming that you are connected wirelessly, the bars indicate the quality or strength of the signal from the modem/router to the laptop.

They do NOT represent the speed at which websites may be accessed or data downloaded, or indeed uploaded.

If you are connected wirelessly, then you more than likely have a facility to change the wireless channel on the modem.router. On most it will be set automatically.

Sometimes, other local equipment transmitting a wireless signal, even if not on the same frequency, can because of what is known as harmonics interfere with the signal.

For instance intruder alarms, baby listening devices, etc can fall into this category.

Local VHF, UHF transmissions from Taxi firms, Private Hire etc are also easily capable of interrupting the signal.

Check on your modem if you can change the channel.

In view of this

Right now it appears to be working much better




It may well be such temporary, but regular occurring interruption of your signal.

Another field of examination although not offerred on all modems is this

  • Connection or Sync Speed or Rate
  • Attenuation or Atten or Loop Loss
  • SNR Margin or Noise Margin or Noise or Margin
  • Details of any CRC/HEC/RS/FEC errors and Errored Seconds may also be helpful.

Finally you can easily obtain a speed test of your connection.There are many sites.Probably best as you are in the USA to google it, but this one may be one you could use.

The one I use in the UK is not available to you

If you suddenly lose connectivity over your High Speed Internet line, have a slow connection or are unable to browse the Internet despite indications that you are connected, it is possible that your modem is not communicating properly with the Internet network.

Save all your current work, close all open applications, then shut down your computer ...unplug router and modem

Power up the modem first and after it gets initialized and all the lites are steady..
power up the router...after all the lites are on...
power up the computer

The above steps should take care of your problem

after those steps go here and test your speeds at least 2 places...one close to where you live and one across the country from you...
post those numbers and what speed your paying for so we can compare them

I just tested my speed from a city that is closest to me (400 miles away) and my download speed is 21.62 Mbps and upload is 5.64 Mbps. After testing from a city across the country the speed is 12.99 mbps download and 5.25 upload. Thank you for your help.

AND as I said on my post 6, if it is a temporary occurring slow speed - possibly an interruption to the wireless signal

microwave ovens can cause signal loss as well as fans and cordless phones
