Q: Why does my Wi-Fi slow down when I get my transmitter near my computer?
A: Because Wi-Fi and Line 6 2.4GHz wireless products share the same frequency band-space. Some users may experience a slowing down or even interruption of their Wi-Fi capabilities when using microphone or instrument transmitters in close proximity to their computers or routers. This is an example of a near/far interference problem and it may be intensified because consumer grade Wi-Fi typically has limited RF dynamic range. Using more XD-V channels operating at the same time will create more competition to Wi-Fi than a single channel would.
If your Line 6 transmitter gets within 6 feet of your laptop you may witness this situation especially if your Wi-Fi access point is some distance away. Typically, simply moving your Line 6 transmitter farther away from your computer will remedy the situation.
Users of Line 6 twelve channel systems can switch their transmitters to the “low power” setting as this will mitigate the problem as well. If you are using the system outside the USA you can likely switch your Wi-Fi channels to 12, 13 or 14 depending on your location. The frequencies for these channels are outside the Line 6 2.4GHz frequencies.
Likewise, switching Wi-Fi to 802.11n in the 5GHz band will avoid Line 6 wireless frequencies and double your potential Wi-Fi throughput.
Suggested channels settings to avoid interfering with Wi-Fi:
Wi-Fi Channel Number - Line 6 Channel Number
1 - 1, 12
6 - 2, 6
11 - 5, 8, 9
