Why is the link quality of my ZyXEL Communications Adapter poor?
- J
  Jonathan FloresAug 12, 2025
  If the link quality or signal strength of your ZyXEL Communications Adapter is consistently poor, it could be due to radio interference from devices like microwaves or other access points using the same channel. To improve this, try the following: * Use the Site Survey screen to find and connect to an access point with better link quality. * Move your computer closer to the access point or other computers within the network. * Lower the output power of each access point. * Ensure that not too many wireless stations are connected to the network.

  If your computer with the ZyXEL Communications Adapter cannot communicate with other computers in wireless station mode, here are a few things to check: * **In Infrastructure Mode:** Ensure the access point and associated computers are on and working; verify that the adapter and access point use the same SSID; change the radio channel if there's interference; confirm that the computer and access point share the same security options and key. If using WPA(2) or WPA(2)-PSK, try switching the encryption type between TKIP and AES. * **In Ad-Hoc (IBSS) Mode:** Verify that the other computers are on; ensure the adapter and other computers use the same SSID and channel; confirm that all computers share the same security settings; change the radio channel if interference is high.
