        @asan-nased Hi,

        You can't use ifup/ifdown, we use connman to manage wifi.

        Anyway please check that:

        • your SSID is not hidden
        • your wifi channel is < 11

            @asan-nased ok can you temporary connect an ethernet cable to the rpi ? Then connect to its IP with a web browser, go the support section, launch the support script, and paste the link here.

                @asan-nased all seems to be ok.

                Any special character in your wifi password ? (no need to write it here)

                      There are no filters. I do not see any attempts to establish connection at the router log files. I tested wifi with 2016-05-27-raspbian-jessie.img and it works, than i rewrited recalbox.img at SD card and configured wifi again and i still have this problem.

                        I do not understand why RX packets at WLAN0 interface dropped

                        ifconfig wlan0|grep RX

                              RX packets:143 errors:0 dropped:143 overruns:0 frame:0
                              RX bytes:66349 (64.7 KiB)  TX bytes:0 (0.0 B)

                          @oyyodams said in rpi3 wifi problem:

                          @asan-nased all seems to be ok.

                          Any special character in your wifi password ? (no need to write it here)

                          I have failed to connect to a Wifi with the SSID "GVT-25F0" but then succeded when routing from my phone (SSID: Cheese). If I were to guess, the issue is the "-".
                          Dont know if that helps but I think special characters are a problem on the name aswell.
                          Maybe try renaming the network?

                            I installed a new test router with OpenWrt, created SSID ABCAAA with kea AAAAAAAA and the rpi is still not connect to wifi, RX packets still drop.

                                @asan-nased you can't be connected to ethernet and wifi at the same time. Unplug your ethernet cable first.

                                  Thanks, all is working now, i think the problem was in 11 channel on the router and then connected ethernet
