I was recently on vacation with my family in Ocean City, Maryland. As I powered up my iPad from our fifth floor condo on 136th Street, more than a half dozen wireless networks popped up. I asked myself: Can I use (or trust) any of these? Are they free? Is it worth the risk, if they are?
The names were intriguing to me, ranging from Netgear58-5G to Oceanside136 to OceanNet Public Internet ST to Wireless Beach Access. Some of these networks had locks next to them and others did not. Clicking on a few of the options, I received a splash screen asking for a credit or debit card numbers. The price for access ranged from $4.99 for one hour to $9.99 for 24 hours to $42.99 for one month (31 days).
Others WiFi networks asked for a password, and I am happy to report that the networks were fairly secure. (My son wanted to start guessing passwords based upon the network names or Ocean City street names or boardwalk trivia, but I persuaded him not to go there.)
In case you’re wondering: no, I did not connect to any of these hotspots, and my wife and I preferred to use our Verizon data plans instead. This meant we had to up the number of minutes on her monthly data account, and that cost us an additional $20. I did use the free McDonalds WiFi, and the free WiFi at another restaurant but passed on the others.
But this situation leads to a series of questions that I’d like to address for travelers, such as: are any of these WiFi networks safe? Plenty has been written about airport Internet access and free WiFi in hotel lobbies, but what about wider issues for families traveling on vacation? Are there tips regarding which networks we can trust? Are there certain traps we should avoid?
First, how safe are free public WiFi networks? Well this video claims that WiFi hacking is the fastest growing consumer crime in America. This ABC News video on WiFi networks is also worth viewing. Here’s another good video on WiFi security from central Indiana. One message that is clear is that hackers are setting up fake hotspots to view your personal data.
If you do connect to free WiFi networks, you need to understand the risks and the lingo. Check out this article, which described the different buzzwords that are important. From sniffing to sidejacking to honeypots, this picture offers a great summary of the relevant terms.

Here are some more helpful tips that I found along the way: Five rules for (safely) using public WiFi networks. I’ve abbreviated the list here, but click on the article for more details:
Also, here’s an extended list of tips for using WiFi networks when traveling (the list is from Symantec).
One simple tip is to use a trusted network from the resort or hotel that you’re staying in – if available, such as Disney’s free WiFi. But even if you trust the source, the safety tips are still important to help.
Another good tip is to ensure that your personal firewall is enabled on your PC.
Bottom line, using public WiFi remains a minefield. While avoiding free WiFi is probably not practical for most people, we need to take steps to protect our computers and our families when traveling. Understanding your options is a good first step, but we need to take action on know steps to protect our data on vacation.
Any WiFi tips to share? I’d love to hear about your experiences, so leave a comment.
