PPPoe connection keeps dropping perodically

Hello guys.My internet connection keeps dropping periodically.I get the below dialog box and on clicking 'redial' it connects again but again i get the same dialog box in 10-15 minutes.I use windows 7.Tbh i have 0 knowledge of all this LAN related things so i am attaching screenshots of various details of my PC.Please let me know if you need any more details.







[Here on right clicking 'Local Are connection 2'->properties->configure->Advanced Tab the setting there are:
Flow control - Disabled
InterruptModeration - Enabled
Network address - Not present
Receive Buffers - 160
Speed and Duplex settings-Auto negotiation
Transmit buffers-160 ]





Thanks in advance.

Actually the LAN card as you referred to it is known as a NIC (Network Interface Card). It is then plugged into somthing that looks like a "box with lights". This box with lights may also have an antenna.

Since you are saying PPPoe, that something is most likely either a DSL router and/or modem. If you have more than 1 PC in your home and all can get Internet (wired or wirelessly), then it is probably a router or a combination router/modem. Lets start with solving a few questions:

• Are there any identifiying names and model numbers on this "box"?
• Do you in fact have DSL or ADSL Internet service?
• Who is your provider?
• It appears this is a new att worldnet connection, and that you used to have zonenet... is that the case? You recently switched?

With some of these questions answered, we may be able to assist you with more specific instructions.

I also noticed in the screenshot of your connections that it shows unidentified network, and you have 2 PPPOe miniports shown... delete the old one, or uninstall its software (zonenet).

thank you for your reply Darryl.
My connection doesnt need any box.There is just a wire that i connect to my LAN card and that wire, i think is connected to some switch(a few buildings away) and tbh i dont even know the function of that switch.
There is only 1 PC at my home.
And regarding the 2 miniports,when i connect 'worldnet' its for the internet and 'zonenet' is for 'DC++'.
Also i dont know if my connection is DSL or ADSl.i googled it but still couldnt understand.I have a 512 kbps connection.

that you darryl.I contacted my provider and told him to fix a switch on my building itself.It is an overhead building to building connection and no its not pirated or shared with anyone else.
