![]() ![]() I have heard this is possible for RPi-0W, RPi-3B and RPi-3B+. It is possible to use the wifi device on a Raspberry Pi as an access point and at the same time connect as client to another already established wlan. Ok, I don't know, maybe it's not freshly received, maybe it's remembering the last address somehow. Look at Access point as WiFi repeater, optional with bridge for a more flexible setup. But the hotspot is not active, and the IP address that I get with ifconfig wlan0 is the one that is properly assigned by the router's DHCP. There are two wifi network configurations, one for the router, another for my mobile hotspot. When the device spontaneously reconnects, there are no connection problems, both from Pi and to Pi. Running $ sudo wpa_cli -i wlan0 reconfigure does not fix the situation.Īnd then, after a while, spontaneously, it can suddenly reconnect and everything is fine until it's not again. Running $ sudo iwlist wlan0 scan gives a list of available networks, so apparently there is no problem with the antenna. ![]() Actually, when trying to ping the Pi from another PC, instead of "Destination Host Unreachable" it just gets stuck, ping does not generate new retries. ![]() But it can neither be pinged from another PC in the network nor the router address 192.168.1.1 can be pinged from the Pi. Running $ ifconfig wlan0 shows that it has received its assigned IP address .x. The device boots up and the boot log kind of confirms that connecting to the network is successful: Started WPA supplicant What could be the possible explanation for the following WiFi connection problem: So it's a big pain if the WiFi connection goes bad. Most of the updating/debugging is done via an ssh connection. The device normally does not have a keyboard and display attached, as it's operated by hardware switches and sensors. I have a Raspberry Pi Zero W project that needs a network connection for some of its functionality. ![]()
