If you are not carrying a mobile phone and hate to turn on the laptop or computer just to check if there’s a wireless network around, try this Wi-Fi enabled T-Shirt.
The wi-fi shirt is made of pure cotton, can detect wireless networks in your vicinity and displays the signal strength as animated glowing bars.
This Wi-Fi detector, that works with 802.11b or 802.11g networks, requires four AAA batteries and you can detach this unit from the T-Shirt to avoid any damage at the time of washing.
WiFi T-Shirt
The Wi-Fi T-Shirt costs £19.95 and is available on Amazon (https://www.amazon.co.uk/Blue-Signal-Wifi-Detector-T-Shirt-Black/dp/B0041ZJ9D4?th=1).
If this idea of wearing a T-shirt to detect wireless networks doesn’t sound appealing, try a standalone Wifi seeker( https://www.amazon.com/Mobile-Edge-MEASL1-Signal-Locator/product-reviews/B0002QWU4Q) that’s small enough to fit on a keychain.
The device is equipped with a wireless network signal strength indicator that allows you to determine the availability as well as the quality of the wireless network – even before you boot-up your laptop.
