I’ve tried to use the tinker app as well as setup over usb but both of these attempts fail. Once the wifi details are specified via the usb setup it connects me back to my old wifi- the particle never attempts to connect to wifi (the led never starts blinking green). I did update the firmware to 0.4.3 but to no avail. Any other suggestions? ---

I was able to get wifi set up via particle serial wifi, but the light is now blinking cyan and never hits the slow blink stage. Additionally particle serial mac or particle serial identify is giving me an error. ---

Fairly sure I updated at one point last night. I’ll double check to be sure. ---

Yeah particle-cli is up to date, no further luck getting the particle to work. It may be a DOA one? ---

Why does `particle serial wifi` say? Make sure the Photon is in Listening mode. ---

Blinking cyan means it has connected to WiFi, but cannot connect to the cloud. Please check that your router has DNS correctly configured (so that [device.spark.io](http://device.spark.io) can be resolved) and that port 5683 is open for outgoing traffic. ---

I did a nslookup and the [device.spark.io](http://device.spark.io) address did resolve. I also messed around in my router and set the cube as the default DMZ device but that didn’t seem to help it get past blinking cyan. Is there any sort of logging to see what the issue is? ---

To get some logging, you’ll need to use the local build system and compile with [debugging enabled.](https://github.com/spark/firmware/blob/develop/docs/debugging.md) To be honest, I’m not sure that wil help much - there’s not a lot happening - it resolves the name [device.spark.io](http://device.spark.io), and then tries to connect with TCP/IP to the resolved IP address on port 5683 - once that happens the LED will start to blink cyan quickly. ---

Looks like there’s a build error in the latest version of /latest that prevents the debug mode from working: ``` In file included from ../services/inc/debug.h:1:0, from ./inc/socket_hal.h:34, from src/photon/socket_hal.cpp:26: src/photon/socket_hal.cpp: In function 'int read_packet_and_dispose(tcp_packet_t&, void*, int, wiced_tcp_socket_t*, int)': src/photon/socket_hal.cpp:643:53: error: 'sd' was not declared in this scope DEBUG("Socket %d receive fail %d", (int)sd, int(result)); ^ ../services/inc/service_debug.h:98:138: note: in definition of macro 'DEBUG' #define DEBUG(fmt, ...) do { if ( __LOG_LEVEL_TEST(DEBUG_LEVEL)) {log_print_(DEBUG_LEVEL,__LINE __,__ PRETTY_FUNCTION __,_FILE_PATH,fmt,##__ VA_ARGS__);}}while(0) ^ src/photon/socket_hal.cpp:657:56: error: 'sd' was not declared in this scope DEBUG("Socket %d receive bytes %d of %d", (int)sd, int(bytes_read), int(available)); ^ ../services/inc/service_debug.h:98:138: note: in definition of macro 'DEBUG' #define DEBUG(fmt, ...) do { if ( __LOG_LEVEL_TEST(DEBUG_LEVEL)) {log_print_(DEBUG_LEVEL,__LINE __,__ PRETTY_FUNCTION __,_FILE_PATH,fmt,##__ VA_ARGS__);}}while(0) ^ make[2]: *** [../build/target/hal/platform-6-m/./src/photon/socket_hal.o] Error 1 make[1]: *** [hal] Error 2 make: *** [/Users/Trinity/GitHub/firmware/modules/photon/system-part1/makefile] Error 2 ``` Beyond that. I’m not sure what else to say- DMZ mode should allow full access to the internet bypassing any firewall. I did recently switch routers when while I was waiting for my photon upgrade so I’m unsure why it would suddenly start having issues now. One other thing I did notice, the photon doesn’t seem to respond well to static allocation requests from the router. I tried to assign it a fixed ip via the router but it would not respect it and kept getting a different ip. ---

The debug build was fixed after the 0.4.3 release and is in the develop branch. But I really don’t think it will help you, there isn’t much output that can help troubleshoot. ---

> [@jetuser](#): > > One other thing I did notice, the photon doesn't seem to respond well to static allocation requests from the router. I tried to assign it a fixed ip via the router but it would not respect it and kept getting a different ip. I don't believe that's technically possible that the photon can make up it's own IP and ignore the one allocated - that sounds pretty unlikely. 😄 DHCP is used either way if the router allocates the same IP or a varying IP, so I'm inclined to believe there is some issue with your router setup if your seeing the photon get a different IP to what your expecting. ---

I’ll mess around more with the router to see if something funny is going on, but i doubt this since DMZ mode didn’t work on the cube. On a possibly related note, does it mean anything when the cyan blinks rapidly followed by what i think is an orange led blink (it’s really quick) and does this a couple of times before it settles into blinking cyan? ---

When cyan blinks rapidly then it has a connection to the cloud. When it blinks orange, that means you may need to reflash keys to the device. > [@Photon setup flashing cyan with a "quick red burst" (now orange burst) \[Solved\]](https://community.particle.io/t/photon-setup-flashing-cyan-with-a-quick-red-burst/12118/19): > > Sorry for the late follow up. Had a few people with this issue, so now I see the pattern and the solution. NB! only do this if the device has NEVER connected to the cloud before and has the intermittent red blink while fast flashing blue.
