It's not only Wi-Fi that will be hit by climate change; the report also warns of the need to strengthen power cables to avoid sagging, to cover roads with a new surface to protect tarmac (crushed rocks, tar) from melting, and rail-tracks to be made heat-resistant to reduce the chance of buckling. Spelman predicts that £200 billion ($327 billion) will be spent improving infrastructure over the next five years to make these changes, but the question of how to weather-proof Wi-Fi signals remains—pun intended—up in the air.
