Can't connect to WiFi of certain SSIDs

[bortyr]

The name of WiFi's SSID will have an impact whenever the connection will be successful or not.
I performed a set of tests with different kinds of names just to see what what works and not:

OK - WiFi connection successful, LED is green and a POST request is sent to Ambi correctly
FAILED - WiFi connection failed, LED is red

# SSID
TP-Link_4AD4 - FAILED
borys2g - OK
1234567 - FAILED
1 - FAILED
a - FAILED
aaaaa - FAILED
aaaaa2g - OK
aaaaaa - OK
aaaaaaa - OK
aaaaaaaa - FAILED
aaaa_2g - OK
aaaaa_2g - FAILED

# PASSWORD
75884345 - OK

Notes from this:

• It seems to be a recurring pattern that string with over 7 chars will fail (but so did 1 char "1" or "a")
• The "aaaa_2g" showed that "_" character went through correctly
• Password being 8 chars long wasn't an issue
