Linksys WRTP54G router

Linksys WRTP54G router is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Linksys WRTP54G router rather than just read about it. In short: Linksys WRTP54G is a Wi-Fi capable router with VoIP capability from Linksys. Launched in 2005, it is similar in function to the popular WRT54G, the device is capable of sharing Internet connections amongst several computers via 802.3 Ethernet and 802.11b/g wireless data links, but it also has two POTS ports for VoIP telephony.

Key takeaways

Linksys WRTP54G router belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Linksys WRTP54G router to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Linksys WRTP54G router from memory before moving on to harder problems.

Reference excerpt

Linksys WRTP54G is a Wi-Fi capable router with VoIP capability from Linksys. Launched in 2005, it is similar in function to the popular WRT54G, the device is capable of sharing Internet connections amongst several computers via 802.3 Ethernet and 802.11b/g wireless data links, but it also has two POTS ports for VoIP telephony.

VoIP service providers The router was being sold pre-configured for providers Vonage and EarthLink, but was also available without any pre-configured service. In the latter case one needed to configure the VoIP settings oneself. It sold for about $130 on launch, with a Vonage monthly plan of 500 VoIP hours priced at $15, after a $45 service charge. A PC World staff blog post in 2005 warned the reader not to be misled to think that the initial, and the only advertised price, was the total cost of ownership.

Phreaking potential An Associated Press story from August 2006 reported that "Arias Hung, a security professional with Media Access Guard in Seattle", showed how to change the MAC address of a device registered for Vonage service that "could intercept calls made to a legitimate Vonage user and make calls that would appear to come from the user's phone number," recommending that "The general consumer should stay away from this router."

Internals In a departure from most of the WRT54G series (which featured mostly Broadcom chipsets) this router features a Texas Instruments chipset. Texas Instruments chips are common to almost all current Linksys VOIP products. The screws to open the unit are under the rubber pads. These units are often locked with a particular VoIP vendor's information. A Freeware program "cyt46.exe" can help.

Worked examples

Example 1 — a first encounter with Linksys WRTP54G router

Start with the simplest possible case. Write down what Linksys WRTP54G router claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Linksys WRTP54G router before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Linksys WRTP54G router ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Linksys WRTP54G router

In research: Linksys WRTP54G router appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Linksys WRTP54G router in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Linksys WRTP54G router is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer hardware stubs, Hardware routers, Linksys, so understanding it makes those chapters shorter.
In everyday life: Look for Linksys WRTP54G router outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
