NEED HELP PLEASE with tweaking my Internet on my laptop and desktop

[trogers]

Ping times are okay. Some applications will face slowdown due to the double NAT.

For speed of 3 mbps, set TCP Window to 63888 with RWIN scaling off. RWIN scaling adds a little more overheads.

Try the following with TCP Optimizer:

General Settings tab:
Custom settings - check
Modify All Network Adapters - check
network adapter selection - your NIC
MTU - 1492
TTL - 64
TCP Receive Window - 63888
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
TCP 1323 Options:
Windows Scaling - uncheck
Timestamps - uncheck

Advanced Settings tab:
Max Connections per Server - 10
Max Connections per 1.0 Server - 20
LocalPriority - 1
Host Priority - 1
DNSPriority - 1
NetbtPriority - 1
Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0
ToS: DisableUserTOSSetting - 0
ToS: DefaultTOSValue - 80
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768
Then select "Apply Changes" and reboot to take effect

here is my tracert now for my desktop:

Your desktop is connected to the modem with its built-in router. I know this because the modem's router has the IP address 192.168.1.1

Your wireless router has the IP address of 192.168.0.1

Your modem is being placed near to some other electrical device and it is suffering some electrical interference. I can tell because ping times to the modem in hop 2 are higher then those at hop 3 to 7. And hop 7 is probably from an intermediate router many hundreds of miles away from you, so why is your modem responding slower when it is only a few feet away?

What you want to do is the following:

Set modem into bridge mode and save and reboot the modem to retain this setting.

Disconnect your desktop from the modem and connect the wireless router to the modem. Press the little reset button at the rear of the wireless router for 5 sec and let it reset to factory default and establish a brand new connection to the bridged modem.

Connect your desktop to the wireless router by ethernet cable and run setup wizard and input the username and password given to you by your ISP when requested.

When your connection is tested okay, leave the desktop connected to the wireless router and setup the laptop to link through wireless.

Your wireless router is now the only router both comps are connected through.

Follow the networking tips in the Wireless section of our forum to add security and better signal transmission for wireless.

thank u very much for the info....but I do not know how to set modem to bridge mode...do I disconnect it first from the router? I am not sure what to do?

I appreciate your help a lot.

Does my speedtest and tcp analyzer look good or better?

Your speed is already near to 90% of 3 mbps and TCP settings are correct when testing through a direct connection to the modem/router.

Power off the modem and place it in a location a few feet away from ALL other electrical devices. This should clear the high ping times at hop 2. Setting up a signal device require a direct cable connection from your comp to the device. So you need to connect the cmp to the modem to set it up. And in later step, you need to connect your comp to the wireless router to set it up as well.


To set the modem, you need to read its user manual. If you do not have one, Google for it using its model no.

WOOOOOWW!!!!

Look at these results I got now on my laptop:



Thank you so much for your help guys. TRogers and RoolingStone....thank u very much.
