Ask LH: How Can I Get Wi-Fi At A Location That Doesn’t Offer It?

Dear Lifehacker, I often find myself in places in a hotel room where there’s a wired ethernet connection, but no Wi-Fi. I don’t want to be tethered to one spot! How can I add Wi-Fi to one of these places cheaply? Thanks, Wire Free

Dear Wire Free,

While many places do have Wi-Fi these days, it sucks when you get to your hotel for a holiday or conference to find out that the room has wired ethernet and no wireless. It’s not difficult to fix, but you do need to exercise caution about how you do it, and some methods require more tech-savvy than others. Let’s examine a couple of options.

Use A Wireless Router In Bridge Mode

When I travel, I always pack one of the old-style Airport Express models in my laptop bag. I can plug it into the wall, plug in an ethernet cable in my hotel room, and use my laptop anywhere in the room, or connect my Wi-Fi iPad to the network if I choose. The same applies for university dorm rooms, board rooms or other locations with only wired connections. You can optionally install the Tomato or DD-WRT replacement firmware on your router to add lots of useful features, including bandwidth throttling, added security tools, reporting and monitoring, and access controls.

A Word About Security

A little security through obscurity is a good idea too. If you’re using your network in a hotel that’s packed with convention attendees, hide your SSID and keep your network to yourself. The last thing you want to do is wind up inadvertently running an open network, and get into trouble when someone else does something illegal on it.

Turn Your PC Into A Wireless HotSpot

If you don’t have the budget for a wireless router, or left yours at home, you’re not out of options. You can always use Internet Connection Sharing on your Mac or Windows system to share your connection with other devices nearby. We’ve shown you how to do this in Windows and in OS X before, and the basic premise is simple: as long as your laptop is connected to a wired network, you can turn your PC into a hotspot for your tablet, phone, or other devices to connect to. It takes a little setup, but once you’re finished, you won’t even need the router. You have to make sure the PC that’s sharing its connection is on and online at all times.

Buy an 3G/4G Hot Spot

For regular travellers, a Wi-Fi hotspot is the most obvious choice. Both Optus and Telstra now offer 4G options, so you can get impressive speeds. There are prepaid options on Telstra as well, which is handy for less regular travellers.

We hope at least one of these options works for your use case, Wire Free! Remember, be careful with whatever network you set up. With care and caution, you can add the Wi-Fi you need to almost any space. Good luck!

  • I have a TP-Link TL-MR3020 Portable 3G/Wireless N Router and it’s perfect for this. It’s powered using a standard mini usb phone charger, plugs into Ethernet (or a 3G dongle) and shares the connection over Wifi. I often use this in hotel rooms where ethernet is provided and not wifi, or in cases where the wifi is spotty and unencrypted. As with most TP-Link devices, it’s based off of OpenWRT so it’s easy to hack if you want more functionality out of it, but it’s pretty simple to use out of the box I found.
    What’s the cost for one of these devices? Cheapest price on Static-Ice is just $33 ( )

  • Apple Airport Express are great.. the older style ones that plug into the power direct…

    But lately I’ve found it hard to go past the convenience and reliability of my Huwaie E586 personal WiFi Hotspot. Small, easy to carry and I’m not fighting unforeseen network issues at random hotel internet connections. All my devices know my E586 and within seconds I have “my” internet for everything in my room at the hotel.

  • I think that you are mixed up with Bridge mode. Bridge mode is where you have your PC–>Wired–>Bridge Mode (BYO)–> Wireless–>Wireless Access Point–>Existing wired network.

    What you are talking about is Wireless Access Point, which goes PC–>Wireless–>Access Point (BYO)–>Existing wired Network.

    Wireless Access Point is a standard feature on all Wireless routers, whereas Bridge Mode is not (thus DD-WRT is the most surefire way to get it). Many routers have a mode to have it permanently configured as a Wireless Access Points, and for those that don’t have this “mode” it is just a case or turning off the DHCP feature and then plug in one of the 4 LAN ports into the hotel’s wired LAN and leave the WAN port unused. Very important to turn off DHCP or else you are going to cause havoc on the network and you’ld probably be booted out when they find you.

  • Hah! Doing this right now with a D-Link DIR-600 flashed with Dd-wrt. Has been working a treat in the Japanese hotels I have been staying. It’s a comfort to just plug in the router and know that I can access the web with our devices without any hassle. Dd-wrt is running in gateway mode, auto detect internet connection via dhcp, plug the lan cable into the internet port and gtg. As mentioned above, have setup wireless with wpa2 sec and access control on known Mac addresses. Setup the router before I left the country and haven’t had to touch any setting once while traveling. Truly PNP when arriving a new location. 🙂
