Hi, i am having problems with my LAN connection. Usually everything runs really fast and downloads go really fast too. but a few weeks ago for some reason my connection has been going slower than a 56k modem... i am connected to the internet and everything works but very very slow, its been like this for weeks. Does anybody know whats wrong? thx
 
I don't but your provider might. I would get in touch with them first.

The answer has always been 42
 
that speed test said this: your speed < 5211 kbps

Download time for 2MB: 3 seconds
Your CURRENT throughput is: 667 KB/sec
5211 kbps


First off, that can't be right, because i timed how long that speed test took to work (dl the 2Mb file) it took 7 and a half minutes, plus i ran a speed test on this website
which said: 35 Kbps - You 35 kbps

and this website which said Download speed: 50 kilobits per second
Test details: 101 kilobytes downloaded in 15.937 seconds.


whats wrong with my connection?
 
Have you checked with your service provider?

The answer has always been 42
 
can anybody tell me what could be wrong without mentioning the service provider?
 
Sure, Mention your Computer, your OS, the speed of your NIC, the topology of your network. Print IPconfig /all (in Windows) or IFconfig (in unix) Give us some clues.

I tried to remain child-like, all I acheived was childish.

Hi TooCool100,

jimbopalmer means that we (the forum readers) want to know the Speed&Duplex setting of your Network Card.
(NIC stands for Network Interface Card)
We also like to know the complete path from your PC to the Internet (this is the Topology of your network).
In other words: How is your computer connected to the Internet?
Do you use a DSL modem, a switch, a hub, Cable, Satelite.....

 
I would also ring your ISP, you could spend hours playing around with things that have worked just fine and do not need to be changed, and get nowhere.

It could be a problem on their end. Thats the easiest thing to check so its worth doing that first.

If it has been working fine with no changes then I can't see much relevance in wanting to know such things as the speed and duplex of an NIC!

Do you connect through a router? Or straight to the internet via cable modem? What speed to the two little flashing computer icons at the bottom right hand side of your screen indicate?

'When all else fails.......read the manual'
 
With no changes on your end, use the pathping command to see if there is a limiting router along the way dropping packets. Pathping your ISPs DNS server addresses, then pathping a clean website such as yahoo.com. Few if any lost packets should occur. Adjust your MTU if you have lost packets.

Are you sure that your netmask is set properly? I haven't seen anyone use a Class A netmask in nearly 15 years.

I would have expected a netmask like 255.255.255.0, (Class C) or so. That netmask is so large, that your interface is having to assess every packet from a 66. address as if it might be destined for your computer, rather than being able to discard most of the packets based on the netmask.

The gateway is within the 24-bit netmask, so it should not affect your ability to connect to the Internet if you specify a 24-bit netmask.

You might want to check your ISP's configuration page and make sure that the netmask that you are using is correct.
