Randomly laggy DSL

well i didn't configure that much less know how so :| ill work on that asap

First get email access to the help desk.
then copy the tracert in post#1, #15, #18

I wanted the ipconfig /all when directly connected to the modem as it would disclose the ISP configuration instead of that for your router.

Okay, i just disabled IPv6 and restarted my computer, and ill get that ipconfig for you asap.

did you give up on me? =(

No, but all the evidence in this thread point to either

1. your Modem/router or
2. your ISP

IMO, You need onsite, hands-on service.

I notice that ping -l 732 137.118.216.1 works well
while ping -l 800 137.118.216.1 fails

suggest you change the MTU on your system to 732

here's how

If you set the MTU size for a network interface manually, this setting overrides the default MTU for the network interface. The MTU size is the maximum packet size in bytes that the transport will transmit over the underlying network.

This method affects packets sent to all destinations and may significantly affect the performance, depending on the MTU size that you set.

To set the MTU size for the network interface, follow these steps:

1. Click Start, click Run, type regedit, and then click OK.
2. Locate the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<ID for network interface>
3. On the Edit menu, point to New, and then click DWORD Value.
4. Type MTU, and then press ENTER.
5. On the Edit menu, click Modify.
6. In the Value data box, type the value of the MTU size, and then click OK.
7. Quit Registry Editor, and then restart the computer.

Done! thanks for all your help, much appreciated ill let you know if this MTU helps any.

Quick question, Does that MTU change work with a router, and if it does do they need to change there MTU settings for it to change for them?

yes, setting the MTU in the router enforces a common MTU to the whole lan - -
but try it out first one one system

Iv done it, Didn't help at all im going to give my ISP a call now since they won't answer my emails thanks for all your help.

Be sure to tell them all the things you tried and about Jobeard's tips. Just because they gave you a new modem, it doesn't mean that it is good. Have them swap it out again
