Um, firewalls are
not intermittent as described in the original post - they usually
work or
don't work, not both. Usually it is a configuration issue. Turning off your firewall for even a few seconds is
very strongly not recommended. Time to compromise in the modern Internetz world can be measured in seconds - I've seen it with my own eyes with a sacrificial honeypot device. Once you are compromised, all bets are off.
On that subject, have you run a malware/virus scan lately and done a software update on all devices, including your cell phones? Often manufacturers will slide in subtle fixes to major problems and only document the bigger issues to save embarrassment. Malware will often alter your device characteristics, often drastically as it attempts to replicate and destroy.
