If you paste the following into notepad and save it as a reg file and enter it to the registry I am told it will help with PPPOE. I am on dialup so I cannot say if it works, I'm told it does by some XP users on DSL.

In the hour of 11:49 AM 21/03/2003 -0600, [EMAIL PROTECTED] spoke this:
I am REALLY confused here with MTU settings in XP. Ben said XP has no MTU settings in the registry and a key had to be added. http://www.winguides.com/registry/display.php/280/
Then I asked: ------------------ I notice they don't list a figure for routerPPPoe. Ok...so what is the default value?
I don't understand that page. It says "find the key below", and there is no key below. Do they mean this key, or is this what you ADD?
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\ Parameters\Interfaces\[Adapter ID]]
Now I have that key, but under Adapter ID I have 3 entries. Do they mean to add the new key immediately after that "adapter ID", so when it's highlighted you see the new entry in the right pane? -----------------------------
I still need to know about the difference in those settings with a router PPPoe. It's usually less than 1492 with a router. I know the formula for finding the optimal MTU, but it might not work with XP. So, before receiving a reply to that question above, I right clicked the right pane AT THAT KEY ABOVE, and added this:
Value Name: MTU Data Type: REG_DWORD (DWORD Value) Value Data: Default = 0xffffffff
(Is that the correct place to add it?) I had to figure out the conversion from Hex to Dec with a scientific calculator. You cannot simply enter an MTU setting, you must enter Hex to Dec conversion equivalent. Meaning, if you want 1500 MTU, at the Dword you must enter 5DC. Now, am I doing that right? Because I went and tested my MTU again, and it's STILL saying the SAME MTU setting as before! Even stranger, from what I was able to find out, XP has a default MTU of 1480, yet I'm told mine is 1440 here http://forums.speedguide.net:8117/ and at http://www.dslreports.com/tweaks ! If this method of changing it above IS correct, why is it not working? If it's not correct, then how exactly is the MTU changed?
Could the default MTU have been changed somehow by my NIC (Intel Pro 1000MT), or my router (DLink DI-704)? I'm on an ADSL connection.
Does anyone have any idea why I can no longer connect to my router's control panel? This is that webpage looking interface where you change settings. All you do is enter the IP in the address bar for the router, and the interface comes up. Now, I get 'the page cannot be displayed', yet the title bar shows the correct name, DI-704! Could this have anything to do with not being able to change the MTU (IF that is I was doing it correctly above)?
I also saw this: "As of 10/15/01, there is no way known to raise MTU in WinXP from 1480. This issue is seen only by WinXP users who are connecting with the built in PPPoE connection software*. If you change to RASPPPoE, or use a router instead, your MTU should then default to 1492. RASPPPoE is popular, free, and less problematic than WinPoet (another choice).
This small difference (12 bytes) in MTU is negligible however, and should cause no concern. Check back from time to time though for a "fix"."
This too states 1480, yet mine is 1440, and even now after downloading an "MTU tool", I STILL cannot change it! *How do I know if I used this connection software they speak of? I was not aware of it. I didn't have to configure ANYTHING. All I had to do was install the NIC drivers, and that was it. No settings had to be checked. Immediately after the NIC's install, I was online. Evidently, I didn't use the software. ? -Clint
