Dsl problems????

[sspryte]

Ok I have been dealing with dsl problems for a while now. I am getting ready to pull my hair out!
Let me give you the run down. On the first of the month I had my dsl speed bumped up from 1000 to 3072. And it has been giving me fits ever since. I keep losing my adsl connection. I have had my dsl provider check the line. They say everything is fine. I have replaced my modem twice....I have replaced all my cables...It loses connecion at exactly the same time everyday. 8:30 pm....and does nto become active again until 8:30 am....I have tried rebooting the modem...no go. I have tried rebooted the pc.....no go....The lights on the modem are like this: power=green status=blinking adsl=on and off ethernet=green. I am using a d=link modem right now.
I am thinking it has something to do with the dhcp server and the lease? But I am a newbie with all this networking and I am kinda lost.
Can anyone PLEASE help me??????

Are you using a router? It sounds like you might be limiting the connection to a 12hr [period (if using router) Try looking for that property, or just reset the router... and set it up.

If only a modem, try reseting the modem after the 8:30 time (when you loose connection) and see if it will connect with a fresh restart. If you can set the lease time set it to "0"

yea i would have to agree with trizoy sounds to me like your setting a lease period and it can be changed to 0 and you wont loose it

Ok I went through my event viewer. And I DID start having dhcp problems as soon as my dsl provider upped my speed from 1000 to 3072. It keeps giving me the message: Description:
The IP address lease 217.51.40.109 for the Network Card with network address 0013D4D96B33 has been denied by the DHCP server 192.168.1.1 (The DHCP Server sent a DHCPNACK message).

OR

Description:
Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address 0013D4D96B33. The following error occurred:
The operation was canceled by the user. . Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

Does this help in anyway?

The assignment of the IP address usually expires after a predetermined period of time(lease time), at which point the DHCP client and server renegotiate a new IP address from the server's predefined pool of addresses.
Important:
Configuring firewall rules to accommodate access from machines who receive their IP addresses via DHCP is therefore more difficult because the remote IP address will vary from time to time. Administrators must usually allow access to the entire remote DHCP subnet for a particular TCP/UDP port.

Do you have a firewall?
You have a few options... test the firewall idea.. (turn them all off, even winxp) Then see if it shuts off at 8:30. IF it still shuts off it is someother kind of problem. Call the owner of the DHCP server (the ISP) and tell them your Lease time for the IP address is only 12hrs.. and needs to be increased.

ALSO, try this on another computer.

OR Try to allow DHCP through your firewall

To allow DHCP, network administrators need to allow several types of packets through the server-side firewall. All DHCP packets travel as UDP datagrams; all client-sent packets have source port 68 and destination port 67; all server-sent packets have source port 67 and destination port 68. For example, a server-side firewall should allow the following types of packets:

Incoming packets from 0.0.0.0 or dhcp-pool to dhcp-ip
Incoming packets from any address to 255.255.255.255
Outgoing packets from dhcp-ip to dhcp-pool or 255.255.255.255
where dhcp-ip represents any address configured on a DHCP server host and dhcp-pool stands for the pool from which a DHCP server assigns addresses to clients
