Unstable Internet Connection?

At this point I would suspect that your live trading software may be causing problems with your connection.

what you may do to source the problem.
Note the google IP (ping google.com).
When things start to become messy, then ping your gateway, if ok, ping google IP, if ok, ping google url, if OK, telnet google.com 80 then type anything+enter, you would see a HTML bad request from google.
If all the step above are working then you do not have issues accessing internet, so it would be software that is crazy.

I'm not to sure how to ping something? is that in the cmd ? ping 192.1.... (gateway Ip)

which then gives u this info?

Ping statistics for 192.1....

if OK, telnet google.com 80 then type anything+enter, you would see a HTML bad request from google. ??? i dont get this part

here what you has to do under CMD:

Code:

ping google.com, and note the IP, here 209.85.229.147
C:\Users\bastien>ping google.com

A successful ping give you a response time in millisecs.
If it work, try to test your dns:

Code:

C:\Users\bastien>nslookup google.com
Serveur :  XXXXXXXXX
Address:  XXXX

Réponse ne faisant pas autorité :
Nom :    google.com
Addresses:  209.85.227.106  !see here some google IP, not mandatory same as above
          209.85.227.147
          209.85.227.99
          209.85.227.103
          209.85.227.104
          209.85.227.105

then try to establish a connection to google:

Code:

 C:\Users\bastien>telnet www.google.com 80

It shouldn't have any errors, and depending if you are behind a firewall, you may get strange characters appearing with a bad request message, but it can also be blank.

Howdy.

I'd like to suggest taking a look at your Network adapter. Start -> dev manager -> network adapter. Double click, open her up and then under "advanced", take a look at "Link Speed & Duplex".

If this is set to auto-negotiation, try re-setting it to 10 or 100mbps Full Duplex, re-start your computer and see if the problem persists.

For whatever reason, auto-negotiation features in some network cards poor.

Good luck!

Hey. Did you find out what i it was?

My computer is VERY slow on the internet sometimes, but my laptop is okay. WTF?

Im pretty good at computers and network, and i just cannot seem to find the problem.

The internet connection is VERY unstable. When i run speed test i get 0.5 mbit or 8 mbit. Depends on when i do the test. The upload is always good?

My laptop is showing about 4-5 mbit, and suddently in the last part of the test, it jumps up to 60 mbit or so! wuuut?

I only have 10/1

I have a linksys repeater thingy, then a linksys N wifi AP and then the ADSL router.
