Help on tweaking barelly broadband connection.

[Tio-Fu]

Well, I put another cable at my home, on the other PC, to avoid the stress regarding shared Internet connection (like donwloads while I'm playing). The another cable is 64kpbs/64kpbs... almost a modem. But it seems that this new cable sucks, while the other doesn´t. Well, so I´m here for a little help...

The TCP Analyzer test:
TCP options string = 020405b401010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 1460
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 1460
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 58.4 kbps (7.3 KBytes/s) @ 200ms
Your RcvWindow limits you to: 23.36 kbps (2.92 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.

MTU Discovery (RFC1191) = ON

Time to live left = 117 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

SpeakEasy.NET test:

2003-02-26 22:57:03 EST: 43 / 59
Your download speed : 43038 bps, or 43 kbps.
A 5.2 KB/sec transfer rate.
Your upload speed : 59171 bps, or 59 kbps.

Running Win98SE...
Well, that it, help me with that issue.
Thanks

PS: if it has any value, this cable is more used for gaming....

Id try a minimum rwin value of 8760 for your connection.
Hopefully one of the genius' will help you here.

To be honest ur speeds are as close to that connection as u are going to get but if you want try this

i say try a higher rwin of 51100 if you have the tcpopimizer installed select custom on the bottom and cable on the top put that 51100 for default recive window 1500 mtu
mtu discovery yes
black hole detect no
selective acks yes
ttl 64 apply changes and reboot

Also please read read 1st below me in my sig thank u

To be honest with you, I'm not so sure of it...

My download rates are so unstable that on Quake my ping go between 50 and 600, because the cable can´t send the packets with an 5000bps rate (my cable should be able to get at least 6000 because the server that I play is very good and somewhat close to my house).

I have to put a rate of 3800, and with my 33.6k USR modem I used to get 100 - 130 of ping with a 3600 rate on the same server...

Thanks mcofee, the settings you gave me seems to be OK right now.

Someone else know the correct values for cablenut settings for a 64/64 Cable?

Thanks again.

[mnosteele52]

For 98SE and a 64/64 connection use the following settings:

BcastNameQueryCount - 1
BcastQueryTimeout - 100
BSDUrgent - 1
CacheTimeout - 600000
DefaultRecvWindow - 8760
DefaultTTL - 128
EnableDNS - 0
GlobalMaxTcpWindoSize - 8760
KeepAliveInterval - 500
KeepAliveTime - 14400000
Lanabase - 0
LocalCopyMade - 1
MaxConnections - 64
MaxConnectRetries - 5
MaxDataRetries - 64
NameTableSize - 255
NameSrvQueryTimeout - 100
PMTUBlackHoleDetect - 0
PMTUDiscovery - 1
RoutingBufSize - 146432
RoutingPackets - 100
SackOpts - 1
SessionKeepAlive - 7200
SessionTableSize - 255
Size/Small/Medium/Large - 3
Tcp1323Opts - 0
TcpTimedWaitDelay - 30
MaxDupAcks - 3
DefaultTOS - 92
IGMPLevel - 2
MaxConnectionsPer1_0Server - 8
MaxConnectionsPerServer - 4

VERY IMPORTANT TO DO THE FOLLOWING

1. Under your Configuration tab for your Network settings make sure you have only the needed protocols.

2. Install the vtcp 386 patch and the NDIS Update from here.

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

4. 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.

5. Clear your temporary internet files.

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

7. Download and update then do a scan with SpyBot & Ad Aware 6.0 to remove any spyware then install and update SpywareBlaster to stay spyware FREE.

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

OK thanks

Hey mnosteele52, what about for XP? what are the cablenut settings for XP on the 64/64 connection?

I see you have it for win98, but I have XP, so thats why I ask the question. vbmenu_register("postmenu_945586", true);
