If you have a weak wifi signal at your device (e.g., laptop, TV, Roku, etc.), you will experience slow speeds, disconnects, and poor Internet. To troubleshoot the problem, try these steps:

• If the device is a laptop, tablet or smart phone (something mobile), try moving closer to your router. If the signal improves, then your device: 1) may have been too far away from your router to maintain a good signal, or 2) something may have been blocking the wifi signal from getting to your device (e.g., brick/stone wall, refrigerator or other appliance with a magnetic motor, metal wall, etc.).
  
  
  
  If you are standing right next to your router and have a poor wifi signal, then: 1) either your router's wifi hardware is failing, or 2) your device's wifi receiver is failing. To troubleshoot which it may be, use another device (e.g. laptop, smart phone, tablet) and check the wifi signal on that second device at the same location as the first device (side-by-side wifi comparison). If the second device's wifi signal is also weak, that suggests the router's wifi hardware is failing. If the second device's wifi is strong, that suggests that the first device's wifi receiver is failing (or it needs a firmware/software update).
  
  NOTE: your wifi signal strength is not a measure of Internet service but a measure of "how close" you are to your wifi router (proximity bars). The closer you are to the router, the more bars, and vice versa.
  
  Possible solutions are: 1) replace an older router (>5 years old) with a newer router; 2) add a repeater/booster to your existing network; 3) raise your current router up higher and make sure the antennas (if available) are pointed properly.
  

• If the device is a desktop computer, Smart TV or streaming player attached to a TV (a stationary device), use another device (e.g. laptop, smart phone, tablet) and check the wifi signal on that second device at the same location as the first device (side-by-side wifi comparison). If the second device's wifi signal is also weak, that suggests the router's wifi hardware is failing or is too far away. If the second device's wifi is strong, that suggests that the first device's wifi receiver is failing (or may need a firmware/software update). 
  
  If this is the first time you are seeing this issue, 1) your router's antennas may be blocked, or pointed downward, or 2) you possibly have some kind of competing wireless device(s) operating (e.g., see interference devices).
  
  On some occasions a firmware/software update may fix the problem on streaming devices (e.g. Roku, AppleTV). Check to see if a new firmware is available. Even many brands of Smart TVs actually have software updates that come out 1-2 times per year.
  
  Possible solutions are: 1) replace an older router (>4 years old) with a newer router; 2) add a repeater/booster to your existing network; 3) raise your current router up higher and make sure the antennas (if available) are pointed properly.
