As we have customers receiving their units, and we are getting questions, we use this blog to answer. It will all go to a new Q&A page soon within our support page:
Q) The device does not always detect a paired device, either with a protection icon or a 5GHz warning.I've even tried it with devices immediately next to the wifi wall.
A) 1. Normally, when a paired device is connecting to a 2.4GHz network, WifiWall will move from the scanning screen (rotating radar) to the main screen (breathing shield).
However, if the protected device is connected to a 5GHz network, WifiWall will display the message 5GHz and stay in the scanning/radar screen. New generation routers, may switch the paired device from 2.4GHz to 5GHz without you getting any indication to that except in WifiWall.
2. WifiWall may display the scanning screen when your protected device is in sleep mode (battery saving). After an about 20 seconds in which there was no activity in your protected device, WifiWall will switch to the scanning screen. Wake your device and within 10 seconds, WifiWall will switch back to the main screen.
3. If the protected device is connected to a 2.4GHz network and active, WifiWall will identify Wifi packets going from/to the device and will move from the scanning/radar screen to the main screen, showing the name of the 2.4GHz Wifi network with other information.
4. However, please note that the protected device is equally protected when you are connected to a 2.4GHz network, regardless if WifiWall display the scanning screen or the main screen.
Q) How does WifiWall detect a paired device and switch to main screen?
A) WifiWall monitors all the Wifi traffic in the vicinity. Its range is similar to your phone's Wifi range. Every Wifi device, periodically sends 802.11 management frames to the router its connected to (and may send message to other routers in the area too) including announcing switching to sleep mode and wake up messages. WifiWall monitor all 802.11 frames and uses its own internal protocol analyzer to track the status and activity of the protected device. Depends on the situation, WifiWall will switch between scanning screen and main screen, however, in each of them, WifiWall is protecting the paired devices.
Q) My 2nd paired device icon is not showing in the main screen? does this mean that It's not protected?
A) If your 2nd paired device is connected to a different Wifi Network, and the 1st paired device is connected and active (icon is showing on main screen) - you will not see its icon. Please make sure that both protected devices share the same Wifi network so both icons will appear and both devices will be protected. The answer is the 2nd device connected to a different Wifi network is protected, is more complicated: if the "other" wifi network share the same channel number as the first network, the answer is yes, it is still protected. The problem is that normally without special App running on the device, you will not know it. Therefore, we recommend keep using the same Wifi network on both.
Q) I received the Alert screen, what shell I do?
A) Alert message in a public Wifi network is a strong indication of an attempt to attack your device. This may be an attempt to divert your connection, hijack your connection etc. WifiWall will send Wifi (802.11 management) frames to your device advising it to disconnect, however, we strongly recommend you to avoid using this public WiFi network for the next 15 mins. Later you may reconnect, but if this happens again, avoid this WiFi network for the entire day
Q) You identify paired device via its Mac address, how can I find my Mac address?
A) Android and IOS devices reveal their Mac Address within the General menu. You can do a quick search for Mac address and find it there. Same for Windows and MAC OS X devices. Another way to find your Mac Address is using WifiWall. When you pair your device, WifiWall record its Mac Address and display it in the splash screen and in the Status screen along side with the selected icon.
Q) What is the shield coding for Wifi encryption:
A) The following are shields code:
- no shields: no encryption
- 1 shield: WEP or WPA1
- 2 shields: WPA2
- 3 shields, reserved for WPA3
- 4 shields, reserved for WPA3
Q) How do I know that I paired successfully?
A) Check the splash screen of WifiWall (when it boots). If at least one of the Mac addresses is not showing ff:ff:ff:ff:ff:ff - you are paired. If you are paired with two devices, both numbers should be the Mac addresses of your paired devices.
Q) How can I tell if my phone is connected to a 2.4GHz or 5GHz network?
A) You can use WifiWall. Open your Wifi Selection screen in your phone (must be previously paired with WifiWall) and look on WifiWall scanning screen. If you are connected to a 5GHz network, you will see 5GHz on WifiWall screen. If you are connected to a 2.4GHz network, WifiWall will switch automatically to the main screen displaying you r 2.4GHz network name.
Q) Does WiFi Wall interact with any servers and if so who's (yours or third parties) and under what circumstances (i.e., not at all, only for firmware updates, or regularly when used)? Will there be any firmware updates (or are they not needed)? Does any user data ever get passed to or through servers?
A) If you did not set a WifiWall Wifi network (you need a special Phone App for that, check the user manual), there is no server connected to WifiWall. If you did connect WifiWall to a Wifi network, WifiWall will anonymously report Attack Alerts to our cloud server, and will receive anonymously Attack Alerts from other people devices. In future, we will have update service that will also require a Wifi connection.
Q) Will WiFi Wall add any value after WPA3 generally becomes available? Will WiFi Wall be compatible with WPA3
A) WPA3 will be widely available sometime after 2020. Until that time, WPA2 is a huge problem (as the WPA3 designers admit today). By that time, we will have the hardware accelerator for WPA3, and we plan to support it.
While WPA3 solves some WPA2 issues (check KRACK attack), it will still suffer from others, and while we hope not, our experience shows us that attackers will find weaknesses, and our mission is to help on that :)
Q) Do I understand correctly the WiFi Wall battery is internal? Is it user replaceable? If so is it a standard battery? Will WiFi Wall work if the battery fails as long as it is powered externally? Can WiFi wall be left on charge when not in use without adversely impacting battery life (i.e., does it use smart charging to prolong battery life / stop charging when no more charging is needed)?
A) Yes, it is internal (optional) battery, Lipo type, and custom made. It is rechargeable and cannot be replaced. Yes, WifiWall will work any time its connected to external power (USB cable) even if the battery fails. You can leave WifiWall to charge or in its cradle, and during this time, it will not consume battery while working (smart charging is active).
