If you have those old fillings, stay away from the WiFi router!
Effect of radiofrequency radiation from Wi-Fi devices on mercury release from amalgam restorations
"...Results: The mean (±SD) concentration of mercury in the artificial saliva of the Wi-Fi exposed teeth samples was 0.056 ± .025 mg/L, while it was only 0.026 ± .008 mg/L in the non-exposed control samples. This difference was statistically significant (P =0.009). Conclusion: Exposure of patients with amalgam restorations to radiofrequency radiation emitted from conventional Wi-Fi devices can increase mercury release from amalgam restorations."
