Wifi connection problem

Hi, I am finding it impossible to get an ESP8266 to connect to my router. I have tried a large number of different scripts from the internet on both a D1 mini and a full sized D1. Both run the blink script etc. OK but neither will find my router. A Raspberry Pi I just got found it immediately and connected without problems as did a Philips Hue hub. The only thing I can see which might be causing a problem is that my router is set on channel 3 as a large number of routers in the surrounding area are permanently on channel 1. The 'net seems totally devoid of useful information to cure this - can any of you offer any help please?

ESP8266 is very frustrating to start with. It may take a lot of debugging to figure out the problem.
I'll start here: Is the code uploading successfully? What is your flash burning tool? Are you choosing the flash-size properly when uploading (depends on your uploader)? Are you uploading esp_init_data_default.bin and blank.bin to 0x3FC000 and 0x3FE000 respectively? (Beware, different upload addresses for different flash size settings, 0x3FC000 and 0x3FE000 for 32MBit i.e. 4MByte flash sizes)
I'm not a pro here, infact I have a lot of troubles recurring on my ESP12-E but I'll try to help if you can respond to above.
