why does my internet speed vary so?
I did a few speed tests when something I was streaming was loading absolutely awfully. Normally I can watch it straight off but it would only give me two minutes at the time, then completely forget to keep buffering so I'd have to reload the page.
In the two minutes I spend doing a handful of those speed tests, I got speeds ranging from 5.5 - 19.5 mbps, yet even the peaks didn't seem to affect the buffering speed. It's still crawling.
A month ago I posted about really slow wireless but with a high (20mbps) theoretical maximum. I never did find out the speed for that time because I couldn't even load those test pages... I thought I resolved the problem by following the advice I got on here and changing the channel of the Wireless.
Windows Vista, Wireless (Netgear, wireless N), close proximity to router, CPU usage and physical memory fine.
Many thanks

Most Internet connections are shared (all actually). Even DSL which is a dedicated line to the Service Provider is shared, because all of the customers of the Service Provider use the same connection to the Service Provider or the Service Provider. Was that confusing? I guess it was. There are large Internet service providers called tier 1, they sell service to tier 2 providers and they sell services to the little tier one providers, and they sell it to you.At each step of the way, the pipe gets smaller, and the more users at each level, the slower it gets.

Comcast broadband provider distributes in a shape the place a node is the crucial element on your community. A node is a gadget that centers x volume of clientele. Bandwidth is shared between all clientele connecting to the node. that's as much as the cable provider to furnish sufficient bandwidth to the node. All clientele, even with speed tier and repair kit, will share a similar community node from the cable company. Node saturation could reason speed subject concerns, yet whilst the equipment is geared up real, you will no longer have this concern. you are able to observe particular cases of the day that your speed varies? My wager is that on weekends and nights whilst extra every person is homestead you will see some overall performance lag. Then on weekdays, you will probable observe larger speeds because of the fact much less every person is homestead employing the internet.

Are you uploading anything? In utorrent, emule, limewire, stuff like that? Because if you are, and you did not set an upload limit slightly lower than your maximum upload capacity, your download will suffer.
If I remember correctly, the limit should be at around 90%: if you have 1 Mbps upload (officially), that's 128 KB/s, multiplied by 0.9, it's 108 KB/s.
If you're not uploading anything I don't know what the problem is.
