Many of us whizz our way to the relatives’ for the holidays, carrying with us a plethora of electronics. Sadly, on arrival, we find that our cousin canceled cable service because of cost, snow downed a DSL drop, or mom and stepdad’s new house in the woods is in a cellular coverage shadow—no LTE nor even a sketchy EDGE signal to be found for miles!
Best Travel Router For International Travel
What can you do? Prepare before you go for the worst-case scenario. There have never been more options for acquiring high-speed Internet access even when a feed isn’t convenient. That counts for your old family home or a hotel.
Best Travel Router: 5 Portable Small Wifi Routers 2018 best buy Get Wi-Fi Access anywhere with the help of a pocket router or a good travel router Finding the best travel router is.
(Tip: If you’re planning to rely on mobile broadband, visit your carrier’s site and use the coverage maps to see if you can receive high-speed data where you’ll be. These maps are estimates, not guarantees, but it’s still a good way to avoid unpleasant surprises—such as entirely empty areas of coverage.)
Use your iPhone or iPad as a personal hotspot
The best mobile modem is the one you have with you. Apple’s Personal Hotspot feature has been a go-to (or carry-with) option for us since iOS 4. Launch Settings, tap Personal Hotspot, and tap On. (If you don’t see Personal Hotspot in the main Settings view, tap Cellular > Personal Hotspot.)
iOS lets you tether via USB, or connect wirelessly via Bluetooth or Wi-Fi. Bluetooth requires pairing, so that your computer or other iOS device first prove their respective identities to each other. Wi-Fi uses a password, which iOS helpfully prefills to something strong. You can change it, a good idea if you’re going to share the connection temporarily and don’t want others to connect to it automatically in the future.
Tip: The Wi-Fi connection turns off if it’s not used within a short period of time. You have to toggle Personal Hotspot off and on to connect once that happens. And another tip: Personal Hotspot only works with WPA2 Personal encryption enabled, and some much older devices (pre-2004, typically) won’t be able to connect.
You can combine two kinds of sharing while charging your phone or tablet: use USB for the connection, and then, in Sharing preferences, turn on Internet Sharing over Wi-Fi. Select Internet Sharing, then choose iPhone or iPad USB from the Share Your Connection From Menu, and check the Wi-Fi box in the To Computers Using list. Finally, check the box next to Internet Sharing. Click Wi-Fi Options to set a strong password.
(If you don’t happen to travel with an iPhone or iPad, or have an older model or a restricted cellular plan, most other modern phones and mobile-enabled tablets include a mobile hotspot feature, too, that typically works best over Wi-Fi.)
Personal Hotspot is included in all current major carrier plans, but because these plans also include bandwidth limits after which you’re charged more or throttled, be sure to disable high-bandwidth background activities that could accidentally run up charges. File sync systems like Dropbox and cloud-based backup are two big culprits.
Bring a mobile router
You can still use mobile broadband without relying on your phone or tablet by opting for a mobile hotspot. This is especially useful if you want to provide access to multiple people, such as members of your family, without being tied to any one person’s hardware.
The MiFi was the pioneer in this field, and you may still hear mobile hotspots referred to generically by that name. But now there are many brands to choose among. Carriers offer them directly—AT&T offers three LTE-capable models, for instance, along with both contract-free and subsidized options, down to $0 with a two-year plan.
Modern mobile hotspots typically have a battery life around 10 hours, although they can be used while plugged in at a house or hotel, too. Many have touchscreens for configuration, but all newer units at least have an LCD display showing status and data consumed.
If you already have a data plan with a carrier, you can typically add a mobile hotspot as another device for $20 per month, and tap into your existing bandwidth pool.
You can also buy GSM-based unlocked, contract-free hotspots from Amazon and others, sometimes under $50 for older but capable 3G/3G+ models. These units work on AT&T and T-Mobile’s network in the US (and most networks in the rest of the world), but you need to obtain a SIM and add the device to a plan to use it.
If you’d like to bypass service plans altogether, you have a couple good options in the US. Virgin Mobile, a division of Sprint, offers only no-contract usage plans with BroadbandBand2Go. (Virgin Mobile uses Sprint’s 3G and LTE networks when you’re researching service areas.) After purchasing a hotspot from the company—it currently offers only the NetGear Mingle Mobile Hotspot—you can then pick short-term service plans.
Virgin Mobile charges $5 per day with a cap of 250 MB. Monthly plans run $25 for up to 1.5 GB and $55 for up to 6 GB. The unused bandwidth expires at the end of the period. If you use up the bandwidth before the duration of the plan, you can simply pay to purchase another plan.
AT&T also offers a pay-as-you-go mobile hotspot with LTE support. Its plans are $15 a week or $25 per month for up to 250MB of access, and an extra $10 for each 100MB unit during those periods. A $50 monthly plan includes 1.5GB, and runs $10 per 500MB units above that.
As with Personal Hotspot use, beware background high-bandwidth-using software, lest your allotment be sucked up and you are charged many overages.
Deal with a distant signal
Your parents opted for broadband, but the modem is at one end of the house, and your childhood room, where you’re crammed into a bed a foot too short for you, is at the other. Alternatively, you’re now sleeping in the basement with wedges of concrete between you and an upstairs Wi-Fi router.
Bring a base station: The easiest way to deal with a weak broadband signal is to bring a Wi-Fi base station of your own. The AirPort Express ($99) is compact and packs a powerful signal. You might already be using one in your home as your main base station or as an extension. (You can sometimes find these as warranted used items in Apple’s refurbished store. There’s currently one there for $75.)
The newest AirPort Express has two ethernet ports, so you can connect it to an existing broadband modem, if that modem has LAN (Local Area Network) ports available. Bring an extra ethernet cable, and plug the LAN port of the modem into the WAN port (a little halo of dots) on the AirPort Express.
Many modems come with a single LAN port, however, and that one might be occupied by a wired computer, smart TV, or other devices. This requires a bit more planning. Online stores offer 4-port or 5-port 10/100 Mbps ethernet switches for around $10. Grab one of those and bring *two* ethernet cables. Unplug the ethernet cable from the modem’s LAN port, and plug that into any available slot in the switch. Now run one cable from the LAN port on the modem to any port on the switch, and another from any port to the AirPort Express’s WAN port—identified by a little halo of dots.
Opt for the electrical system: But what if, as in our speculative case, the modem is at one end of the house and you want to curl up at the other, and the signal won’t reach? Try powerline networking, sometimes sold as HomePlug or other marketing names. This technology pushes networking mojo over home electrical wiring.
Because the signal is carried on a particular power phase—don’t ask, it gets way too complicated—you can only expect outlets that share the same circuit breaker to carry the signal efficiently. Other outlets might work at a fraction of the maximum speed. However, that lower speed likely exceeds the Internet connection’s rate.
Prices on powerline adapters have dropped to ridiculously low levels in recent years, so if you avoided this option in this past due to cost, you can take another look. A pair of adapters with one or more ethernet ports on each end costs from $35 to $60 with maximum potential rates of several hundred Mbps. For $20 to $30 more, you can pair an ethernet powerline adapter with a Wi-Fi powerline adapter, and pump out wireless signal anywhere on the same electrical network.
Remember to pack ethernet cables and potentially a switch (see above) to connect to the broadband modem. If your Mac doesn’t offer ethernet, get Apple’s USB ethernet adapter (10/100 Mbps) or, for newer Macs, Thunderbolt to Gigabit ethernet adapter (10/100/1000 Mbps) for $29 each.
To Xfinity and beyond
Subscribers to several cable networks, including Comcast’s Xfinity and Cablevision, have access to hundreds of thousands of Wi-Fi networks around the US. Originally, Cablevision and then other cable operators installed their own hotspots in urban areas.
More recently, Comcast activated Wi-Fi networks on its customers’ home routers using what the company claims is separately provisioned bandwidth that won’t take away from home users’ service. This action has added a huge number of hotspots in residential neighborhoods, and I’ve seen such networks all over as I travel—you might be able to get better service from a neighbor than the house (or Airbnb or hotel) in which you’re staying. (If you’re a Comcast customer and want to disable the feature, Comcast has an answer in its FAQ.)
Because most cable operators are exclusive in their markets, the big ones allow other companies’ customers to use their hotspots, too. After connecting to a cable-company hotspot, you should be prompted in a browser or pop-up Wi-Fi login screen to enter your account information. Once you’ve logged in, you should never need to do so again, anywhere! The network stores your computer’s unique Wi-Fi adapter’s numeric identifier in its database.
Free networking at a hotel
If your travels take you to a highly capable budget motel or the lap of luxury, you may be implored to pay an absurd nightly or per-stay rate for ethernet-based or Wi-Fi access at the joint—sometimes $10 to $15 per night. Oddly, the less expensive the hotel, the more likely they throw in Internet service at no charge: Best Western provides it free everywhere in the US and in some other locations. Marriott offers it free at its budget and mid-tier chains, but charges at high-end hotels. (Some hotels also offer tiered Wi-Fi, where “slow” service, which is often quite good, is free.)
Avoid these charges entirely through a Personal Hotspot or mobile hotspot as described earlier. (Hotels cannot block your Wi-Fi usage, though some try.) But you can also often get this pricey Internet service for free. Sometimes, just asking at the front desk will get you a free code for one or more nights. In other cases, opening an account with the hotel’s free affinity program before a visit will add wireless access at a free or reduced rate.
The Points Guy, a site for rewards-savvy travelers, has a reasonably up-to-date accounting of each major American hotel chain, and what you need (if anything) for free service.
Macs 2018 Best Travel Router For Hotels Using A Macbook Air
Relax a little
One of the joys of travel is supposed to be breaking your routines. It’s true that many employers want you to stay connected even when taking time off, but if you can’t make your internet access work, consider taking this as a sign. It may be time to slow down and hit the off button.
Glenn Fleishman, Macworld’s security and privacy columnist, once owned a 110-baud modem. He misses it still. He’s the author most recently of Take Control of Your Apple Wi-Fi Network, with details covering Mac OS X and iOS. You can find him on Twitter @glennf.
Macs are fairly secure by default, but that doesn’t make them impenetrable. Use these tips to make sure you secure your Mac as much as necessary.
1. Turn on FileVault
FileVault is a whole-disk encryption system. It wraps all the contents of your disk in an layer of encryption. This means that even if attackers have access to your physical hard drive, they cannot decrypt the data without your password.
FileVault is turned on by default in all new Macs. But if you have an older Mac, or you used a Time Machine clone to copy your Mac’s files to your new machine, FileVault might not be turned on. You can adjust this under the “Security & Privacy” pane in System Preferences.
2. Choose a Complex Login Password and Use It
While this tip is most important for users with laptops that travel, it’s a good tip for everyone. Using FileVault won’t matter if your password is “password.” This setting is also found under the “Security & Privacy” pane in System Preferences.
Of course, that password doesn’t do any good if you don’t use it. Make sure you set your computer to require the password as soon as it sleeps. If you use a desktop Mac, get it the habit of manually sleeping your computer to ensure it’s always protected. Also disable auto-login and ensure you’re setting your Mac to sleep after a few minutes of inactivity as a fail-safe.
3. Use a Password Manager
These days secured personal data doesn’t tend to exist on your Mac’s hard drive. Instead, it lives in the cloud, in social media accounts, and in remote backups. Unless secured with a complex and unique password, that data is vulnerable to silent, remote extraction.
Download a password manager like Dashlane and get started using it right away. Use the password generation tools to replace duplicate or simple passwords with long and complex ones. Also, turn on two-factor authentication for any accounts that support it.
4. Employ Encryption Selectively
For highly confidential documents, you’ll want to encrypt them separately from your whole-disk encryption scheme. 1Password actually offers the option to upload up to 1 gigabyte of files which are secured with the same method that protects your password. You can also use stand-alone encryption software like Encrypto. For the thinnest but most convenient layer of security, you can set passwords on PDFs with Preview.
5. Use Find My Mac to Wipe Remotely
Turn on “Find My Mac” under the iCloud System Preference pane. This uses your Mac’s Wi-Fi connection to keep track of its physical location. If the device is lost or stolen, you can find out where it is.
This will also enable you to remotely wipe your Mac if it ends up in the wrong hands. Even if you can’t recover the device, you can make sure information doesn’t wind up in the wrong hands.
It doesn’t make sense to steer people to external GPUs. Comes with warranty here: It is beyond sad that since 2013 Apple has done absolutely nothing to keep its graphics hardware competitive with the rest of the planet. 2018 best graphics card for 2010 mac pro.
6. Ensure Your Firewall Is On and Enable Stealth Mode
By default, your Mac’s software firewall should be on. But just in case you’ve turned it off, take a look under the Firewall tab of the Security & Privacy pane. You can also use third-party firewalls like Little Snitch that offer more complex protection.
You can enable additional protections by turning on stealth mode. This stone-cold preference name keeps your computer from responding to network probing applications like ping. You can find the setting under the “Firewall Options …” button of the Firewall pane, down towards the bottom.
Jan 08, 2018 The rest of the games on this list are titles that may release in 2018 but (so far as I can tell) don't have release dates at all, meaning they could come out in 2019, 2020 or.never. 42 rows With hundreds of new Mac games popping up each month, we prefer to focus on quality and only highlight the games that deserve your attention. In addition, this page covers the top upcoming Mac games for the rest of 2018 and 2019. https://omgwaves.netlify.app/upcoming-games-for-mac-2018.html.
7. Turn Sharing Off Until You Need It
If you use your Mac on a home network frequently, you might have file sharing turned on. If you ever use your computer on a network you do not completely control, you need to turn that off.
It’s best to turn “Sharing” options on only when you need them. This includes File Sharing, Printer Sharing, the whole shebang. It’s better to close up all potential ports when you’re on a public network than risk an unexpected intrusion.
8. Secure Your Network Activity
Your Mac isn’t just about its hardware. It’s also about the networks that your Mac connects to. Poorly secured routers can often be a vector for attack.
Make sure you’re using the most up-to-date firmware for your router and that you use a secure and complex password. If you give your password to any guests, change the password as soon as they are done.
You can further secure your online activity with a VPN. This will encrypt your network traffic, preventing prying eyes from checking in.
9. Encrypt Your Backups
Any smart computer user will have a backup system. But if your backups aren’t as secure as your main drive, they represent a vulnerability. Make sure you encrypt your Time Machine backups under the Time Machine preference pane. Also make sure you encrypt any other backups you have, whether cloned disk or web-based backups.
Conclusion
Use the security steps that are necessary to compensate for your level of risk. Very few of tips will interfere with the normal operation of your Mac. You’ll be more secure without being bothered by it.
