Email and Forum Questions
- Email from Dave in Elkridge: Hello Doc and Jim, I would like to set our Android and iOS phones to only connect to our home Wi-Fi network, and never to public Wi-Fi, whether in restaurants, airports, or wherever. We have a 10GB per month family plan that we never use up, so I would like to stay on the Cellular connection all the time, except when at home. But I don’t want to have to disable Wi-Fi every time we leave the house. When we return to the house, we always forget to re-enable Wi-Fi. Also, out in public, I don’t want pop-up Wi-Fi screens asking me to connect to a public Wi-Fi network. Thanks, Dave in Elkridge
- Tech Talk Responds: You need to forget all networks that you don’t want to connect to. Go to each of those networks and bring up network properties. Then click on Forget this Network. Then you want to turn off Wi-Fi notification when another Wi-Fi signal is detected. Turn off Ask to Join Networks. I did both of these things a while ago and it works like a charm. If you have Sprint, you also have to turn off the Sprint Connection Optimizer. This will also be located in Settings.
- Email from Robert Tyler: Dear Dr. Shurtz: I heard your story on your last show about Bitcoin and thought you might be interested in the Gizmodo investigation that has uncovered new evidence in the search for Satoshi Nakamoto, creator of Bitcoin. Gizmodo and Wired Magazine both conclude that the Bitcoin creators are Craig Steven Wright, an Australian businessman and Dave Kleinman, a computer forensics expert who died in 2013. Both magazines offer compelling evidence that this time they may have the right people who invented the digital currency. Thanks to you and Jim for the great podcast. Long time podcast listener, Carl Tyler
- Tech Talk Responds: This is a great link. I have read about this latest their about Satoshi’s location. Craig Steven Wright seems to fit the bill. There were a series of leaks that led to him. Either he has launched a clever hoax or he is the real deal. I will talk about this at length later.
- Email from Allen in Kansas: Dear Doc and Jim. I have heard many people talk about tracing the route of packets on the Internet to see how many hops there are to get to the destination. How is that accomplished? Love the show. Allen in Kansas
- Tech Talk Responds: This is done with an Internet service called Traceroute. Traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. The history of the route is recorded as the round-trip times of the packets received from each successive host (remote node) in the route (path); the sum of the mean times in each hop indicates the total time spent to establish the connection. Traceroute proceeds unless all (three) sent packets are lost more than twice, then the connection is lost and the route cannot be evaluated. Ping, on the other hand, only computes the final round-trip times from the destination point.
- The traceroute command is available on a number of modern operating systems. On Apple Mac OS, it is available by opening “Network Utilities” and selecting “Traceroute” tab, as well as by typing the “traceroute” command in the terminal. On other Unix systems, such as FreeBSD or Linux, it is available as a traceroute command in a terminal. On Microsoft Windows, it is named tracert. You need to open the command window and type “tracert www.stratford.edu” to check the number of hopes to the Stratford University website.

Permanent Broadband Tax Exemption
- Congress is expected to pass a permanent ban that will prevent local governments from taxing Internet access, a big win for consumers that ensures your broadband bill won’t ever look like your wireless bill.
- If passed, the bill will permanently ban state and local governments from imposing new taxes on Internet access, including broadband service.
- The ban would be good news for broadband consumers, who wouldn’t see tax-related price hikes on their bills.
- The legislation would also phase out taxes over four years in seven states — Hawaii, New Mexico, North Dakota, Ohio, South Dakota, Texas, and Wisconsin — where local taxes were imposed on Internet access before a federal moratorium was passed in 1998.
- Most broadband customers have never been taxed for Net access. Back in ’98, when the Internet was just gaining steam, Congress passed the Internet Tax Freedom Act, prohibiting state and local governments from adding taxes to Internet bills.
- But the fix was only temporary, and every few years the law has had to be renewed. With the latest temporary Internet Tax Freedom Act set to expire, broadband providers and consumer advocates have warned that without a law banning these taxes for good, consumers could see their bills increase.
- President Barack Obama is expected to sign the legislation. He’s supported previous renewals of the moratorium.
