Hi - I have three computers, two desktop and one laptop running on my wireless network at home. They are all running Windows XP. A few days back they all started running so slowly, they're barely usable. I've followed the instructions in the Slow Computer section that I found on your site. Seeing as it is all three computers (and I used the laptop outside of my house and it ran just fine), should I assume the problem is with my service provider?

I haven't done anything or loaded anything on to my computers that would have caused this. I was trying to run an instructional video for something from a site online yesterday and I got the message -- "Sufficient bandwidth not available, network overloaded, try again later". Whose network? Mine or the service providers? I'm at a loss as to where to go from here?
Thanks for any advice you can give.

Sounds like an ISP problem. Or one of your neighbors may be using your wireless or one of your computers has a problem.

Next time you have a problem run the speed test in the link below.

I suppose it could also be a router problem.

Thanks very much. I ran the speedtest and it confirms that all three of computers are running horribly slowly, the laptop the slowest. How would I determine which of the possibilities you mentioned is the culprit?

I don't use wireless, but one obvious thing to do is to connect one of your computers directly to the cable or phone line line to see if the wireless hub or router is the problem.
If you are on DSL it could be as simple as a loose wire or some phone equipment shorting out.
Are you on cable or DSL?
Just a thought, some ISP's limit downloads/uploads to a monthly max.

Try changing the channel your router and computer are communicating on. In the States the default is channel is 6. Select a different channel.

I hooked the cable directly to the computer as opposed to running it through the router and then ran a speedtest. It came
out fine. So the problem isn't with my ISP. It's with my router or one of my computers. Why it started all of a sudden, I don't know but at this point it goes beyond my ability to fix...I guess I'll have to call the Nerds on Wheels or something. But thanks for the advice.

I would pick Acklan's brain for the fix. Or go to Walmart for the router or whatever your hardware setup is.

There are two thing I would try that will only take a few minutes and not cost you a service call fee.

1) Go to the Manufacturer's website, and check for firmware updates for your router. With programs changing all the time and how they interact with other softwares there are aways updates.

2) Use a program called Cablenut to tweak your settings. I personally use it and recommend it.
