Hi, it might work, but it doesn't always work. Stutters can be caused by a variety of reasons, such as network congestion, aging equipment, signal interference, etc. Replacing the router can solve some problems, such as signal interference and device aging. However, if the delay is caused by network congestion, network Settings need to be optimized and network service plans may need to be upgraded. It is recommended to first diagnose the root cause of the problem and then consider possible solutions.
Don't replace the router, buy a new bridge to extend the coverage, and the remote phone surveillance won't be stuck.
