The answer to this is, yes. Wireless routers, like all electric devices, can go bad. Given that they are plugged in almost all the time, any electric surge can cause the router to heat up or get damaged. However, this also depends on the kind of router that you buy. A premium router priced above 200-300 will usually be more resistant to these electric surges and is less likely to be damaged. However, if you go for a cheaper device below 50, thereu2019s a good chance that it can get damaged faster.
