ISP Rogers High Speed

Hi there I am new here and had a question.

Ok up to a week a go my rogers was very fast up to 3.2mb/s on Bandwidth Place speed test now it is around half that at 1.5 mb/s. The other thing is that my connection only seems to be letting me only connect to 28 or so IP addresses before a week a go it was letting me connect to 60 or more IP's/. This is not could since i use P2p prgrams. I have scan for spyware and removed it but still no change. I aslo have cablenut and using some settings in it and have removed everthing in my NIC config accept for the tcp/ip protocals.

MY/TCP

TCP options string = 020405b401010402010303000101080a3a3f983f00000000
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1448, which is less than MSS because of Timestamps, or other TCP/IP options used.

Default Receive Window (RWIN) = 17520
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17520

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: 700.8 kbps (87.6 KBytes/s) @ 200ms
Your RcvWindow limits you to: 280.32 kbps (35.04 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 52 hops

TTL value is ok.
Timestamps (RFC1323) =
Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.

Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

PLEASE PLEASE help me PLEASE

can someone please help

thanks

Sure, we will base your settings on a max latency of 100ms, also you should go buy a NIC and connect your modem that way instead of USB, it's faster and more stable.

Download the TCP Optimizer and try the following settings.

Settings tab:

select - cable modem
check - custom settings
network adapter selection - your NIC
check modify all adapters
maxmtu - 1500
TTL - 64
TCP Receive Window - 20440
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 3
TCP 1323 Options - uncheck both boxes

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. 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 & Ad Aware 6.0 to remove any spyware then install and update SpywareBlaster 1.2 to stay spyware FREE. It is an ABSOLUTE MUST that you use BOTH Ad Aware 6.0 & SpyBot 1.2, don't think you are safe with just one of these apps since one will find what the other misses.

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

ok thanks alot that help a little bit i got it up to 1.8mb/s but is there some cable nut settings i can use as well???

Thanks
