Intel Centrino Wireless-N : Slow internet connection

When the system connected to the router in wired mode we can get the very good internet speed. The Problem identified with Intel Centrino Wireless-N 1030 and 6230 adapter with Bluetooth has low internet speed when we connect the Laptop to ADSL2+ Modem Wireless-N router. This type of router can support upto 150/300 mbps in Wireless - N mode.

The network icon in the task bar shows that the system has intenet access or limited connectivity. But you may experience very low speed internet. This is very specific to the wireless -N adapter 1030 and 6230.

Solution:
In the router side
Open the router by entering the default IP of router 192.168.0.1 or 192.168.1.1
user: admin
password: password

Under setup select the wirless settings page

In the mode section select g & b as mode and save this configuration and logout the router and reconnect the laptop with router in wireless mode.

Now U can have the very good browsing experience in the 802.11g mode even with laptops with Wireless-N adapters, because the adapter will operate in Wireless-G mode.

In your laptop you may change the following things
1. Open the device manager and disable all the Bluetooth devices even it is not connected to any BT devices
2. Disable all Microsoft Virtual adapters connecting via Wi-Fi miniport
3. In the Wireless adapter Properties in the advanced tab change the Power option to higher performance in the battery mode and plugged in mode. The major drawback is it will consume lot of power and reduce the battery life. The workaround is to manually put the Wi-Fi adapter into continuously aware mode (CAM). This disables the PSP feature.
Set CAM by using one of the following methods:
(Using this workaround can cause your Bluetooth device to not receive signals)

In Windows XP:
Intel® PROSet/Wireless WiFi Connection Utility
From the Intel PROSet/Wireless WiFi Connection Utility:
Click Advanced > Adapter Settings > Advanced tab.
Select Power Management, uncheck Default / Auto, and move the slider to Highest / Maximum Performance.

Network control panel applet (NCPA)
Put the wireless adapter into continuously aware mode using the following steps:
Click Start > Settings > Control Panel.
Double-click Network Connections.
Right-click the wireless connection and click Properties.
Click Configure.
Click the Advanced tab.
Select the Power Management setting, uncheck Default / Auto, and move the slider to Highest / Maximum Performance.

In Windows 7:
In the Intel Centrino Wirelss-N 1030 >Properties> Advanced>select 802.11n Mode> set the Value as Disabled>OK.
In this case the disabling Virtual Adapters and Bluetooth devices may not be required.

4. Change the adapter mode to Wireless-G. In this case the disabling of BT devices may not be required.

This problem is due to the simultaneous power consumption of Wireless-N adapter and Bluetooth.
a. Reducing the performance of adapter to Wireless-G mode will reduces power consumption.
b. Disabling all the BT devices increases the availability of power to Wireless-N adapter.
c. All the Intel adapters configured in PSP mode(Power Save Polling). PSP mode is a feature that provides extended battery life for laptop computers.

NetGear DGN1000 - MTU, Partial Loss of Internet Connection, and Performance

MTU (Maximum Transmission Unit) is the largest packet a network device transmits. The best MTU setting for NETGEAR equipment is often just the default value. MTU is sometimes presented as something that can be easily changed to improve performance, but in practice this may cause problems. Leave MTU unchanged unless: You have problems connecting to your ISP, or other Internet service, and either the technical support of the ISP or of NETGAER recommends changing MTU. These may require an MTU change: A secure Web site that won't open, or only displays part of a Web page Yahoo email MSN AOL's DSL service You use VPN, and have severe performance problems. You used a program to "optimize" MTU for performance reasons, and now you have connectivity or performance problems. An easy solution to most problems is to change MTU to 1400. If you are willing to experiment, gradually reduce MTU as described in "Details of MTU", below. How to Change a C

Layoffs Cut Deeper Into Economy....... As Recession Hits Most Industries, Corporate Giants Slash Jobs

By Annys Shin and Neil Irwin Washington Post Staff Writers Tuesday, January 27, 2009; Page A01 The nation's employers, including some of its largest and most sturdy, announced plans yesterday to slash more than 55,000 jobs, a staggering one-day toll that highlighted how quickly layoffs are accelerating and how widely misery is spreading throughout the labor market. The cuts extended to companies that were once considered bright spots in the U.S. economy. Construction equipment maker Caterpillar, whose business last year was bolstered by strong exports, said it would cut 20,000 jobs. Pfizer, one of the giants of a health-care sector that had until recently seemed immune from the downturn, said it would cut 8,000. In all, 22 of the 30 companies that are part of the Dow Jones industrial average have announced job cuts since the economy took a nosedive in October. Analysts say they've been surprised by just how quickly those cuts have added up. The number of people receiving u
