With a Linksys router, your home network can have seamless wireless performance. However, because obstructions are inevitable and security settings are sometimes incompatible, Wi-Fi connectivity and performance may be affected. Listed below are the common factors that affect your router's Wi-Fi performance and what you can do about it.

Router and/or the Wi-Fi devices need refresh
Distance from the router
Incorrect wireless key/password
Outdated adapter drivers
Wireless MAC Filter enabled on the router
Outdated router firmware

Router and/or the Wi-Fi devices need refresh

Powercycle your router to refresh connection. To do this, power OFF the router by unplugging the power cord then waiting for about 10 seconds before plugging it back in. Make sure that the Power light (Linksys logo) shows solid white before reconnecting. 

You can also turn OFF then ON the Wi-Fi switch/button of your computer or mobile device then try connecting again.

Distance from the router

To ensure stable Wi-Fi connectivity, make sure that your computer or mobile device is within the range of the wireless router. Computers or phones may also have problems connecting to the Wi-Fi due to interference from other neighboring wireless devices such as cordless phones and microwave ovens. To avoid wireless interference, changing the channel of your router is recommended. Click here for instructions on how you can change the Wi-Fi settings of your router including the channel. 
 
Incorrect wireless key/password

Connecting to a secured Wi-Fi requires WEP, WPA™ Personal or WPA2™ Personal security key or password. You may encounter this error when you have changed the wireless settings of your router. If you are unsure about your wireless key or password, check the wireless security settings of your router. To do this, log in to your router’s web-based setup page, click Wi-Fi Settings under Router Settings then check the Wireless tab.

QUICK TIP: You can also try removing or forgetting your Wi-Fi profiles or preferred networks. To learn how, click here.

Outdated adapter drivers

Your computer’s wireless adapter performs better if the drivers are up to date. Wireless adapter’s compatibility with Wireless-AC, N, G, A or B standards should also be considered. Contact your hardware manufacturer for complete specifications of your wireless adapter. You can also check the connectivity of other wireless devices within the network. The router should be working fine if all other devices have good wireless connectivity to the network.  

QUICK TIP: To isolate the wireless connectivity issue, you can try connecting your computer or your other mobile devices to other Wi-Fi (coffee shop Wi-Fi, etc.).
 
Wireless MAC Filter enabled on the router

The wireless MAC Filter feature limits the number of wireless clients that will be allowed to connect to Wi-Fi. To learn how to set up wireless MAC Filter on a Linksys router, click here.
 
Outdated router firmware
