| Yep, those lightweights, with those high frequency switching circuits, could interfere with WiFi by injecting switching noise into the WiFi signal, either into the air directly or into the access point's WiFi "radio." Try reorienting the amp and/or the access point by 90 or 180 degrees. Also try reorienting the access point's antennas from vertical to horizontal. If the access point has two antennas, go into the setup routine and disable one of them (if it'll let you do that). Also try backing down to the next lowest WiFi standard on the access point: if it's N, set it to B+G; if it's B+G, set it to B only. There's a couple other things you can try but let's keep it simple for now. |
