    I've been getting a weird Ka alert from my stinger. Directional alerts confirm it's coming from a pizza place. I just got used to it.

    Recently I installed a wifi router in my garage (Ubiquity UAP-AC-PRO), now I get a Ka alert from my garage whenever on my driveway, I am assuming the pizza place Ka is also a WiFi access point.

    Is this a known issue? Are wifi routers causing false Ka warnings on other detectors?

    There's a router at work at the end of the building that used to cause 35.5 false on my redline and mag. Haven't noticed it on the R series though.

    Sure they do/can....look @ the FCC filing for the modules in your Ubiquiti....start at page 8 and go down.....

    There was just a post yesterday about a WiFi dashcam causing falsing on a detector mounted close by: www.rdforum.org: Blackvue DR900 makes Uniden R1 alert to 34.650

    I'm surprised a WiFi access point much further away is causing issues though.

    Are there any satellite dishes in the area? The LO of the receiver has been shown to cause Ka falses in the past. There are a number of threads on it here.

    Interesting. I have the same AP mounted behind the house/garage door (inside the house) but never experienced a false.

    Yeah Mike....like most "radios" some drift...look at the FCC#15 it can/does drift up to where your RD will alert to it.

    Well also another consideration....PoE gives off a freq in the 34 GHz range also

    I get a Ka hit every time I leave my subdivision turning right. Never happens turning left and driving down the road either direction no hits. Mine is 33.7XX, close to 33.8. I have never been able to determine the source and it's been there for at least 2 years every day. Great way for me to verify everything is functioning as I start my day.

    Really! Hope they don't move or cancel their service. I'll be totally lost.

    Home garage location alerts at 35.520-35.526. Sufficiently strong to set off rear sensing when parked facing away from the garage about 10 feet away from the access point.

    The router is powered via PoE, but alerts are at 35.5GHz rather than 34. It is a dual radio router (2.4GHz and 5HGz).
