How to connect the new REACH RS+ or REACH M+ (Reach) to a Wireless Network 802.11 (WiFi)
Reach (App 2.14…) can not get a wireless connection to a FRITZ!Box 7490 (OS 6.93). This device is currently the most common SOHO router in Germany.
Solution: Use an alternative Wifi base station and connect it with an Ethernet cable to the Box. Here a ten year old Speedport W501V worked like a charm. It is also from AVM, the leading manufacturer in Central Europe.
If Reach knows a Wifi Network and this network is on air, then Reach tries connecting to it forever. Even if these tries fail every time Reach does never fall back to its initial Access Point mode – until Reach is rebooted. If Reach knows more than one network, then the risk is high that networks which once gave a successful connection are not selected.
Solution: Delete all unsuccessful networks from Reach and switch all other Wifis off.
Reach does not connect on the WiFi channels 12 and 13 in the 2,4 GHz band.
Solution: Select appropriate channels on your home Wifi.
Reach will not answer DNS requests for http://reach.local.
Solution: Use http://192.168.42.1 when on Access Point Mode. When Reach is connected on Network Mode, try http://reach.[your.routers.DNS-name.here], for example http://reach.fritz.box.
The native Reach Apps for iOS or Android complicate things and may mask some errors. If the name solution shown in the point above fails in your network, try this
Solution: Use the web interface of your router to find Reach or run the command
nmap -sP [your.routers.DNS-name.here]/24, for example
nmap -sP fritz.box/24.
Mismatching encryption systems or password typos may hinder a wireless connection.
Solution: Use an unencrypted network for the first steps. Updating Reach is possible over an open connection.
After an update Reach changes the encryption checksums for its own Access Point mode WiFi and for the known WiFi networks.
Solution: Reestablish the WiFi connections after an update and set the encryption keys again in your device (
emlidreach for Access Point mode) and in Reach (
yourkey for Network mode).
