Kim BrandThe last personal computer you bought probably wasn’t a PC. It was a ‘mobile’ device – a tablet or laptop or smartphone. The common denominator of these devices is their dependence on wireless connectivity to your local area network and/or the Internet. The ‘jack’ is gone.

Wireless Fidelity, or WiFi, has become an expectation at coffee shops, car dealers and college campuses. The modern law office too. But the technology invented in 1999 has succeeded beyond its inventors’ expectations. So like our phone system, nobody was quite prepared for the uses to which it has been put.

A marvel of technology, the radios in almost every device seem to auto-magically connect to networks wherever you may roam. Once you connect, they remember your logon information and make your laptop, tablet or smartphone a part of your host’s network. This is a great convenience if you need to check your email, browse the Internet or update your Facebook page, but as with most digital conveniences today you bear the risk of use.

Some WiFi providers offer Internet as an amenity. It would be odd to walk into a Starbucks today and observe the majority of their guests actually talking with one another. Mobile devices demand connectivity and WiFi is the way that is done. The service is offered on an ‘as-is’ basis and the vendor is usually unwilling or unable to offer tech support, so the typical wireless configuration is ‘Open.’ That means there is no password required and no encryption enabled. Basically, anyone sharing the same connection can snoop on what you send and receive over the host network. As an attorney this should give you pause if you are doing anything other than ordering another pair of shoes from Zappos.

The thing to know about Internet service offered as an amenity is there can be no assurance that anything you do is private. The opportunity for the host to monitor your traffic is obvious – they control the network and may have a duty to prevent certain types of activities: browsing pornography, conducting illicit hacking, spewing SPAM across the Internet, to name a few. Indeed, operators of open wireless networks have been charged with the acts of unscrupulous users. That’s why you often see ‘Terms of Service’ pages that you must click through. It gives the operator cover in the event the FBI shows up to investigate who may have a predilection for illicit materials.

The first layer of security offered by the IEEE 802.11 standard developed by the Institute of Electrical and Electronics Engineers applied a fairly rudimentary encryption algorithm to the information you pass over the wireless connection called WEP: Wireless Equivalent Privacy. It wasn’t. The standard (since 2003) has become WPA2: Wireless Protected Access II. This allows connected devices to encrypt data in a far more secure way. This method introduced more robust passwords and more secure networks. You should still be concerned.

Most law firms want to offer wireless access to their staff and guests. This demands a more complex configuration than simply plugging in a WiFi router from Fry’s. The best systems employ login names and passwords that are managed by your server – but these are expensive. The advantage of this system is that an individual user can be ‘deauthorized’ without everyone else suffering the need to change their credentials. The minimum standard is to isolate the private from the public network by providing a different password to staff than you do to your guests. You should change the guest password frequently.

Another problem with WiFi is coverage. A small office may be well served by a single Wireless Access Point. But a firm with 10 or more offices will almost certainly need two or more. Larger networks require ‘Mesh’ technologies that operate like cell phone towers and hand off users from one WAP to another and share the load. More WAPs can produce congested radio traffic which is hard to mitigate. It gets very complicated very quickly.

WiFi was designed to use standard radio frequencies. The problem with that is that many other devices do too. Cordless phones, motion detectors, microwave ovens and remote control toys all play a part in the general noise within these radio frequency bands. If your WiFi connection always fails around lunch time, ask your colleagues to stop using the microwave. If your wireless network is in an area with lots of other WiFi networks (say an office building) expect the clutter to produce interference too.

Adding ‘bandwidth limiting’ features to prevent ‘WiFi hogs’ from consuming your Internet access is becoming a modern necessity. In today’s world you can never get enough Internet.•

  2. Unlike the federal judge who refused to protect me, the Virginia State Bar gave me a hearing. After the hearing, the Virginia State Bar refused to discipline me. VSB said that attacking me with the court ADA coordinator had, " all the grace and charm of a drive-by shooting." One does wonder why the VSB was able to have a hearing and come to that conclusion, but the federal judge in Indiana slammed the door of the courthouse in my face.

  3. I agree. My husband has almost the exact same situation. Age states and all.

  4. Thanks Jim. We surprised ourselves with the first album, so we did a second one. We are releasing it 6/30/17 at the HiFi. The reviews so far are amazing! www.itsjustcraig.com Skope Mag: It’s Just Craig offers a warm intimacy with the tender folk of “Dark Corners”. Rather lovely in execution, It’s Just Craig opts for a full, rich sound. Quite ornate instrumentally, the songs unfurl with such grace and style. Everything about the album feels real and fully lived. By far the highlight of the album are the soft smooth reassuring vocals whose highly articulate lyrics have a dreamy quality to them. Stories emerge out of these small snapshots of reflective moments.... A wide variety of styles are utilized, with folk anchoring it but allowing for chamber pop, soundtrack work, and found electronics filtering their way into the mix. Without a word, It’s Just Craig sets the tone of the album with the warble of “Intro”. From there things get truly started with the hush of “Go”. Building up into a great structure, “Go” has a kindness to it. Organs glisten in the distance on the fragile textures of “Alone” whose light melody adds to the song’s gorgeousness. A wonderful bloom of color defines the spaciousness of “Captain”. Infectious grooves take hold on the otherworldly origins of “Goodnight” with precise drum work giving the song a jazzy feeling. Hazy to its very core is the tragedy of “Leaving Now”. By far the highlight of the album comes with the closing impassioned “Thirty-Nine” where many layers of sound work together possessing a poetic quality.

  5. Andrew, if what you report is true, then it certainly is newsworthy. If what you report is false, then it certainly is newsworthy. Any journalists reading along??? And that same Coordinator blew me up real good as well, even destroying evidence to get the ordered wetwork done. There is a story here, if any have the moxie to go for it. Search ADA here for just some of my experiences with the court's junk yard dog. https://www.scribd.com/document/299040062/Brown-ind-Bar-memo-Pet-cert Yep, drive by shootings. The lawyers of the Old Dominion got that right. Career executions lacking any real semblance of due process. It is the ISC way ... under the bad shepard's leadership ... and a compliant, silent, boot-licking fifth estate.
