Wireless Bridge Solution


Project 20

Bridging a Gap,


What You’ll Need

  • A wireless bridge—aka gaming adapter
  • Your computers with web browsers

Cost: $30–60 for wireless gaming adapter

For some of us, it is relatively easy to expand our network with wires. We “simply”

crawl under the house or in the attic, run some new wires, drill a few holes, install

a couple of RJ-45 jacks, plug in, and go. For many people—apartment dwellers,

house renters, locations with impenetrable ceilings and walls—expanding a network

connection that requires wires at both ends is at least a challenge, if not impossible.

While a laptop may network wirelessly over relatively short distances, walls,

pipes, electrical cabling, and distance can inhibit connectivity. Taking an example from

popular gaming consoles which have only a wired Ethernet port, some computing

devices such as network-capable printers, simply do not connect and network without

an Ethernet cable. A solution is to use Wi-Fi hardware to extend your network as far

as you can without wires, and then return to wires using the wireless bridge where


Typically, you would specifically look for a pair of wireless bridges—devices designed

to “bridge the gap”—but these devices are usually not in stock at even the most

geeky of electronics stores. If you already have Wi-Fi capability at one end of your

network, you can bridge the gap by adding just one easy-to-find device—a wireless

gaming adapter. As much by coincidence as luck in picking a low-cost solution to try,

I discovered that the D-Link DGL-3420 Wireless 108AG Gaming Adapter, shown in

Figure 20-1, will stretch my LAN.

The D-Link Gaming

Adapter is a small but

powerful addition to

your home network.

By adding a wireless gaming adapter as a network bridge, you can extend your

network well beyond just a length of wire or the range of wireless to include other

wired PCs distant from the main connection point, similar to the network schematic

shown in Figure 20-2. This too can be expanded on with additional bridges, as described

in Project 21.Figure 20-1

What You’ll Need

  • A wireless bridge—aka gaming adapter
  • Leftover nonwireless router from Project 2
  • Your computers with web browsers

Cost: $0

Now that we’ve wirelessly jumped a huge span of real estate from one end of

the house to the other in Project 20, we can reintroduce wires into our extended

network configuration.

Our network continues to grow to include many computers at either end of a wirelessly

bridged network, to the new network scheme of Figure 21-1. All we need is that

old nonwireless router we removed from service in Project 2. Instead of being used as

the main expansion of our one-connection DSL or cable service, and as a firewall, we

reuse this gadget to become part of our local network at the far end of a wireless connection

configured in Project 20. All this takes is a few simple reconfiguration steps to

allow it to accept the IP address of our local network, turn off the firewall, and let it

dish out a new set of IP addresses for the extended network clients.

Estabillo siblings


Its nice to hear from you Lani.

Jocynel mentioned about
you earlier in Facebook,
thus you were added to
Quetegan Offsprings.

I'm Julius Estabillo Sinlao, the
admin of the Quetegan Ofsprings e-group.
My Mom is Generosa Estabillo (Maiden name),
extreme right in the picture below.
Vanessa's Mom is Auntie Lina (in fushcia dress
and second from right).

I'm a divorced Dad with three kids ages 12, 8, and 6.
I live in San Diego, California.

Its nice to meet you,
and looking forward to introducing you to the

Xen Desktop 4 sneak peek

The main presentation
that I attended last Friday
at the New Horizons Sneak Peek
Event is a preview on the Xen Desktop 4.

Xen Desktop 4 Supports:
- Any Desktop (virtual or real), anytime, anywhere
- HDX user experience
- Flexcast Technology
- On Demand Applications

Basically Citrix sales people
did a demo of the usage and performance
of Xen Desktop 4 from a browser in the classroom
and explained its Architectire and

They were giving out arguments why
Xen Desktop 4 is better than their competition
VMWare View product running PCoIP protocol.

They've divided the type of information
being streamed to three parts:

- Desktop OS
- Apps
- User Profile

They're still using their proprietary
ICA protocol and claim that
it runs 90% less bandwidth
using HDX Technology.

HDX TEchnology
- leverage the processing power of the
endpoint device to render the multimedia content.

- Support real time collaboration: bi-directional
audio capabilities. Enables users to connect
audio peripherals: microphones at the endpoint device.

- Supports 3D

- Plug and play enables connectivity for USB,
multiple-monitor, printers, etc.

- best network performance using ICA protocol

- 90% less bandwidth using iCA protocol

Flexcast TEchnology
- Citrix's Solution to deliver any type
of Virtual Desktop or any Hardware
whether its a thin client,
a Desktop PC, a mobile device such as Iphone,
or a Laptop PC.

-This technology is actually not part of
Xen Desktop.

- Requires a license to utilize this, per seat or per user.

Xen Desktop 4 can deliver your Desktop for:
- Mobile users
- Guest (Kiosk)
- Office Worker
- Remote user
- Task user

On Demand Application

-Think Itunes store interface. Users are now
- Application virtualization that can be run
locally or hosted through a Data Center

- scalable

- Supports Open Architecture: Can run on any platform
using Hypervisor, any storage platform,
any endpoint device. Support Plug and Play
with Microsoft products.
