Intermittent Wi-Fi connectivity in a break room during lunch time can often be attributed to interference from common household appliances that operate on similar frequencies. In this scenario, microwaves are a primary suspect. They typically operate at 2.4 GHz, which is also the frequency used by many Wi-Fi networks. When a microwave is in use, it can emit electromagnetic interference that may disrupt the Wi-Fi signal and cause connectivity issues.

This kind of interference is especially noticeable in areas where many people congregate, such as a break room, and where devices might be heavily used during peak times, like lunch. As a result, connectivity may fluctuate, leading to intermittent disconnections or slow performance.

In contrast, while access points rebooting would lead to consistent disconnects, and using cellular data wouldn't directly cause Wi-Fi issues; toasters and ovens generally operate at different frequencies and are less likely to affect Wi-Fi performance in the same way as microwaves. Therefore, the presence and operation of microwaves in the cafeteria is a plausible and common cause for such disturbances during busy periods.
