You're looking for a specification called the operating temperature range of the thermostat or router or both. This is the temperature range within which the manufacturer states that the device will function correctly. For consumer electronics like these, it's typically from 0°C (32°F) up to about 60°C (140°F) to 70°C (158°F). So if ...
I highly doubt that Honeywell would design the system on purpose to disconnect from the network based on the ambient temperature (BUT: I may be wrong about this!). That said, it may be that either your router or the thermostat are starting to have technical difficulties if the temperature drops too low. If you have one lying around, try a different router, ...
No, DON'T splice the 'C' wire that goes to 'Y' -- without a clear picture of the continuity of the wires, that's not what that's asking for. If your HVAC unit does not have a 'C' terminal, you will need to add the C (common) wire yourself. There is an answer here on Stack Exchange on adding a C wire for your thermostat. There's a wiring diagram about ...
You can't simply connect any extra wire to the C terminal on the thermostat. You have to also connect the other end of that wire to the C terminal in the furnace. If you include a photo of the wiring at the thermostat, and a photo of the wiring in the furnace I can give you a detailed list of instructions for hooking it up.
If you noticed, the new thermostat came with detailed instructions and labels for the wires. The new one should have been wired exactly like the old one. IE: R/RW/RC-W-G-C-Y, etc. Without knowing how the old one was wired it is impossible to say.
