Symptom(s):
When a 2.4 GHz cordless telephone is powered on or in use near a wireless LAN access point, network adapter, or another wireless device, the following issues may occur:
- Connection disconnects
- Pauses or disruptions in data transmissions
- Erratic connection behaviors
Cause:
2.4 GHz cordless telephones operate at the same frequencies as 2.4 GHz 802.11b, 802.11g and 802.11n wireless LAN access points, network adapters, and other devices.
Solution:
One of the following suggestions may help resolve the issue.
- Change the location of the Access Point and/or the base of the cordless phone.
- Switch the channel on the Access Point. If that doesn't work, try another channel.
Note: Many 2.4 GHz cordless telephones operate with what is called frequency hopping technology. This technology utilizes the entire frequency range also used by 802.11b, 802.11g and 802.11n wireless devices. Thus changing the channel of the Access Point may not eliminate the interference problem.
- Operate the phone with the antenna lowered, if that is an option.
- Use a phone that is not a 2.4 GHz phone.
