Investigate these options:
Move router to a more central location (free)
Add a WAP (often the best option if installing the network cable is easy)
range extender or repeater (often used if running the network cable is too difficult)
higher gain antenna on wireless router
Replace router with new MIMO router
I have a Belkin router on one end of my house. It is connected between the ISP and my desktop. I have an office on the opposite end of my house where I use an IBM laptop. The problem is the signal in my office is in the 50-60% range. Obviously, as I move the laptop closer to the router the signal improves. Are there any type of antennas/boosters that I can put in my home to ensure that I have a good signal in my office?
