Need DSL(PPPOE) Tweak Help!

[Nefarious]

Im on my friends DSL line that I was talking about before. Same ISP as me and about .25 of a mile away. DSL(PPPOE). I used that TCPOptimizer and I did some tweaking of my own on his 2k Pro system. I had the Setting for DSL(PPPOE) Optimal Settings. He has always been getting this speed and when he has called Prodigy/Pacbell they tell him they don't guarantee speed.
Windows 2k Sys, 900Mhz, 385MBs, and 2 HDDs.
DSL Advertised Speeds -Prodigy DSL/ Pacbell -PHONE CO
1500Kbps/128Kbps

Speed 315(down)/106(up) kbps **
(At least 6 times faster than a 56k modem)


Browser/OS = Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461)

TCP options string = 020405860103030201010402

MTU = 1454
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

MSS = 1414
Maximum useful data in each packet = 1414, which is equal to MSS.
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 255552
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 63888
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
520352 (MSS x 46 * scale factor of 8)
260176 (MSS x 46 * scale factor of 4)
130088 (MSS x 46 * scale factor of 2)
65044 (MSS x 46)

bandwidth * delay product:
Your RcvWindow limits you to: 10222.08 kbps (1277.76 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4088.832 kbps (511.104 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 57 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

EnterNet sets a default MTU of 1454.
The Registry Key doesn't match exactly, but these instructions always seem to do the trick.
1) Go to "Start" menu -> Click "Run" -> Type "Regedt32.exe" -> Click "OK"
2) Go to this Registry Key HKEY_LOCAL_MACHINE/ System/CurrentControlSet/
Services/Class /Net/000n/Ndi/ params/MaxFrameSize/"max" ....Where "n" is a number, but it will be a 00 number
3) Double click on "max" and change the value from 1454 to 1492.
4) Close RegEdit
5) Right Click on "Network Neighborhood" (My Network Places)
6) Choose "Properties"
7) Click on the PPPoE adapter (Efficient Networks)
8) Click "Properties"
9) Click "Advanced" tab
11) Click "Max Frame Size" -> Change to MTU you desire
12) Click "LCPMRU" -> Change to match the MTU you changed in step 11
13) Click "OK"
14) Done!

Win2K has the option in a slightly different place.
1) Right click the Local Area Connection for Your PPPoE adapter, choose "Properties".
2) Click "Configure" -> Click "Advanced" tab.
3) You will then see the options listed (as above)

Nefarious, u can try bob's way... Lobo gave me the same advice and now my maxMTU is what it should be 1492. but just so u know, if it don't work with regedt32.exe, try good old regedit.exe.
and if u don't see the line mentioned, just change any values that says 1454 for 1492. the MSS will take care of itself...

u might have to call ur ISP and ask them to redirect u to ....um i forgot the name just ask them if they can redirect to somewhere to where they can check for bridgetaps or if ur line is capped....i had slow speed and nothing helped so i called and they fixed me up eal quick :P

Try Tcp Recieve Windows of 31944 or 63888, scaling NOT checked in Optimizer
