Need Advice on New Connection

Neptune-Sya · Post by **Neptune-Sya** » Tue May 04, 2004 12:35 pm

Hi,

I just got upgraded to a new connection. I am a Bell Sympatico member who was on the old platform using a 1meg Nortel Modem with the 960/120 caps, and I am now using a Speedstream 5200 modem with the newly advertised 3000/800 cap. I am running Windows Xp Professional with a PPPoE connection.

I was wondering if someone can give me some settings to change to take advantage of this upgrade.

Here are my TCP Analyzer results:

TCP options string = 020405a001010402
MTU = 1480
MTU is optimized for Windows XP PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1440
MSS is optimized for Windows XP PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.

Default Receive Window (RWIN) = 17280
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17280

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
506880 (MSS x 44 * scale factor of 8)
253440 (MSS x 44 * scale factor of 4)
126720 (MSS x 44 * scale factor of 2)
63360 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 691.2 kbps (86.4 KBytes/s) @ 200ms
Your RcvWindow limits you to: 276.48 kbps (34.56 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 120 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

Thanks in advance,

Well… I’m here but not smart enough to help you (not a PPPoE guy). Seeing as how none of us get paid to provide tweaking services (we all have a day job) just hang tight and someone will be along. Got any simple questions I can help you with? I could give you the winning lottery numbers for the next powerball drawing if you like.

pretty good doc give the lotto numbers i need loot

Hi mccoffee,

my speeds are approximately 300/kbps - and sometimes lower. Depends really, it fluctuates alot

Is there a better RWIN value you can have me try?

mccoffee · Post by **mccoffee** » Tue May 04, 2004 10:40 pm

Try these settings in the TCPOptimizer:

Settings tab:

select - cable
check - custom settings
network adapter selection - your NIC
check modify all adapters
maxmtu - 1500
TTL - 64
TCP Receive Window 63360
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 2
Nothing checked under windows scailing

Other Settings tab:

Max Connections per Server - 10
Max Connections per 1.0 Server - 20
Lan Browsing Speedup - optimized

Then select "Apply Changes" and reboot to take effect.

VERY IMPORTANT TO DO THE FOLLOWING

1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.

2. Open IE and select tools - internet options - connections - LAN settings, make sure NOTHING there is checked.

3. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer and set your duplex mode to "auto". If you are using a router make sure you have the latest firmware.

4. Clear your temporary internet files.

5. Power cycle your modem, unplug it for atleast 15 seconds.

6. Download and update then do a scan with SpyBot 1.2 & Ad Aware 6.0 to remove any spyware then install and update SpywareBlaster to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES.

7. Make sure you do the faster web page tweak in my Help & Tips link.

8. If you have Zone Alarm as a firewall uninstall it then visit Zonelabs.com for further instructions on removing it's left over junk.

9. Install Outpost Firewall or Sygate Firewall, both have FREE and Pro versions and are heads above ZA.

10. Scan for viruses with your antivirus app, if you do not have one get one IMMEDIATELY, AVG 6.0 is an excellent FREE AV app.

11. Make sure you have ALL of the latest Windows Updates.

Should I use TCP optimizer or Cablenut? since i already have Cablenut installed and used that previously?

mccoffee · Post by **mccoffee** » Wed May 05, 2004 12:31 am

Try the following in cablenut

DefaultReceiveWindow =384000
DefaultSendWindow = 102400

InitialLargeBufferCount = 200
InitialMediumBufferCount = 480
InitialSmallBufferCount = 640

DefaultTTL = 64
DisableUserTOSSetting = 0

2. Open IE and select tools - internet options - connections -
LAN settings, make sure NOTHING there is checked.

3. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link). If you are using a router make sure you have the latest firmware.

4. Clear your temporary internet files.

5. Power cycle your modem, unplug it for atleast 15 seconds.

6. Download and update then do a scan with SpyBot 1.2 http://beam.to/spybotsd & Ad Aware 6.0 http://www.lavasoftusa.com/support/download to remove any spyware then install and update SpywareBlaster to stay spyware FREE.

PPPoE & wXP means that ruter than staticIP are strongly recomended.
BTW madM.D.

can yours lucky numbers also work in PL ?

Thanks mccoffee,

i just did a speed test and my results were 2486/656

my caps are 3000/800. Is there any way to get a better result fo my upload?

I think I'm only running at 82% of my connection.

nevertheless, thanks for the reply

You can't tweak the upload
