Disappointing speed test for Comcast Internet level that is promised to deliver a 22 Mbps download on March 2, 2009 at 7:20 p.m. Monday.

Comcast Speed at 3:19 p.m. after installation of Motorola SB6120 with Comcast Ultra service initiated. Comcast installation wizard crashed and did not work. A call to a Comcast customer service rep was required to prepare the modem for use. The rep was able to activate the modem from her desk in Texas.

Comcast line workers have been working on lines in backyards during the midnight hours in Arlington Heights neighborhoods. Neighbors around town have seen crews with flashlights in their backyards for the past several weeks. Is this a sign of major upgrades to service? Yes, it is.

A Comcast representative confirms that Comcast’s 6.0/8.0 speed plans will be upgraded and that customers will see a jump in price from 6 to 12 and 8 to 16 for the respective plans.

This speed test shows a significant increase in upload speed, compared to previous tests. Download speed has not changed, but is expected to be doubled when the upgrade process is complete.

Comcast, the largest cable operator and residential Internet service provider in the United States is poised to offer speeds up to 50 megabits per second in 10 major markets, which will enable users to download a high-definition movie in 16 minutes and a standard definition movie in 5 minutes. First market availability is in parts of New England, including the Boston area and southern New Hampshire, portions of Philadelphia, New Jersey and the Twin Cities in Minnesota.

Comcast’s new ‘Extreme 50′ tier for residential users, including up to 10 Mbps upstream service, will cost $139.95 a month. For businesses, it will cost $189.95 monthly, including extra features and support.

The ‘Ultra’ plan for individuals will offer speeds up to 22 Mbps for downloading and up to 5 upstream for $62.95 a month. The business “premium” tier will offer the same speeds for $99.95 a month.

The new Internet plans are only available packaged with Comcast’s cable TV service.

802.11g is rapidly growing in popularity. It is backward-compatible with 802.11b, uses the same 2.4 GHz range, but provides for transmission rates up to 54 Mbps.

Because 802.11g networks operate in the popular 2.4 GHz frequency band, they are  subject to interference by devices such as microwave ovens, baby monitors, and cordless phones. However, such interference generally only causes a decreased data rate, not a loss of connection or loss of data. That disadvantage is offset in normal use by the more robust signals associated with the 2.4 GHz band, which readily pass through solid objects such as interior walls of homes. Since AirPort Extreme operates in the 2.4 GHz frequency band, it is approved for use in the same countries as 802.11b
