Get a powerline Ethernet kit for $19.99

Having Wi-Fi troubles? I've been there. Sometimes you just can't get a signal to go where you need it to go--like from the router in the basement to the bedroom two floors up.

If you like drills and impossibly tight spaces, you can always run some Ethernet cable through walls, floors, and ceilings. It's effective, but also a major pain in the keister.

A much easier option is to use a power-line networking kit, which takes advantage of your home's existing electrical wiring. It's a simple, plug-and-play solution.

And usually an expensive one. Power-line kits … Read more

Xerox PARC founder Jacob Goldman dies at 90

The famed Xerox PARC has lost its founder.

Jacob Goldman, a physicist who started Xerox's Palo Alto Research Center, died on Tuesday in Westport, Conn., at the age of 90.

Goldman was lauded in a New York Times obituary as a "dynamic leader and ardent supporter of innovative technologies."

Launched in 1970, Xerox PARC is known in computer history as the hub that developed many of the technologies we take for granted today. Its scientists and researchers teamed up to design the Alto, the first modern personal computer; laser printing; the graphical user interface; the first WYSIWYG (… Read more

Get a powerline Ethernet kit for $49.99

This is an update of a deal I wrote about earlier this year.

Having trouble getting a Wi-Fi signal to go where you need it to go? It's a fairly common problem: I've been in houses where the signal won't reach beyond one room, let alone between floors. So what are your options?

One option is to run Ethernet cable through walls, floors, and ceilings. It's effective, but also a major pain in the butt.

Heading to CES, Broadcom talks 802.11ac, brings Ethernet to cars

Your wireless network at home, and possibly in your car, is about to get a huge dose of networking supercharge.

In a pre-CES meeting with the press today, Broadcom, maker of chipsets that power popular networking devices, unveiled its plan for the new Wi-Fi specification, called 802.11ac, and demoed its new development in in-car Ethernet cabling technology.

The 802.11ac specification--an industry wireless networking standard confirmed by the Institute of Electrical and Electronics Engineers (IEEE) back in January--is the upgrade to the existing 802.11n specification and is considered by Broadcom to be the standard for the "post-PC era" of data connectivity. Broadcom cited a report saying that currently 55 percent of wireless clients are non-PC, which includes game consoles, set-top boxes, and mobile devices.

Unlike 802.11n, which is available in both the 2.4GHz and 5GHz bands, the new 802.11ac uses only the 5GHz band and incorporates many standardized techniques that help greatly increase both the data rates and wireless range. It's also backward-compatible with 802.11n clients. According to Rahul Patel, vice president of Broadcom's Mobile and Wireless Group, Broadcom's new 802.11ac chips will offer the following benefits.… Read more

Three-deal Thursday: A 10-inch tablet for $269, free DVD rippers, and a powerline Ethernet kit for $50

Apologies for my unannounced absence yesterday; I was attending a funeral and neglected to leave a heads-up on Tuesday.

It seems only fitting, then, that I serve up three sweet deals today. Technically, I've got five, but "five-deal Thursday" doesn't have quite the same alliterative ring.

First up, TigerDirect has the ViewSonic gTablet 10-inch Android tablet for $269.97, plus $7.50 for shipping. It's new, not refurbished, and it comes with 16GB of storage. It's on the chunky side, not unlike the $299.99 Toshiba Thrive from the other day, but the real … Read more

Must-have MacBook Air accessories

The MacBook Air is Apple's new mainstream MacBook, and though the latest version is undoubtedly the best, there are still aspects of this slim laptop that could do with accessories.

Addressing self-assigned IP addresses after installing OS X 10.6.8

After installing an OS update, migrating your system, or otherwise performing a major change to your Mac, you may experience a problem where the system will no longer connect to the network, and upon checking your network settings it will show the system has a "self-assigned IP address." This may be the case even though other devices on the same network are working just fine. Additionally, while it may happen to some Macs, it may not happen to others that appear to be set up identically.

In attempting to fix this problem, people may try repairing permissions, booting … Read more

Fix self-assigned IP addresses in OS X

One common issue that has affected OS X systems is when network interfaces are issued a self-assigned IP address, even though the system is connected to a network with a properly configured DHCP server. When this happens, other systems on the same network (often including similarly configured Macs) will be working just fine, indicating the problem lies with the Mac's configuration and is not a compatibility issue with the networking hardware.

Often when I encounter this issue, I find that people have recently made a relatively major configuration change to their systems, either by updating their OS version, performing … Read more
