Understanding why Wi-Fi is slow in some rooms, common causes, and solutions including Wi-Fi extenders, mesh systems, and powerline adapters.
If your Wi-Fi is fast in some rooms but slow in others, it's usually because the Wi-Fi signal is weaker in those areas. The signal gets weaker the further it travels from your router, and obstacles like walls can block or weaken it.
This is a common problem, especially in larger homes or homes with thick walls, but there are several solutions available.
Wi-Fi signals weaken because:
