According to my computer, I maxed out yesterday at 50.4 mph. The day before, 43.6. Last night, with the bike parked in my living room, the computer indicated that it was going 30.2 mph. It's a Specialized wireless. Has anyone had a problem with the computer going wacky? I thought I had it parked too close to my subwoofer (BIG magnet), but it also does it out on different trails, and even sitting in my car. This just started happening. I've had the computer since December, but just put it on my bike mid-August. It was fine until two days ago.

Anyone?

It needs new batteries, most likely. Either in the unit itself, the base unit, or the transmitter unit. Might as well replace them all at once.

I hope you didnt have it too close to the TV...
I layed my wireless on top of the TV when working on my bike and it made things go wacko...
I finally got a new one, Flightdeck "wired"
No more wireless for me...
try resetting it, replacing the battery and if that doesnt work then you are S.O.L.
good luck

(truly pathetic confession coming...) Well, actually, it was sitting next to the subwoofer, leaning against the TV... so I could look at it all night... Do you think it's wacko for good? I'll do the battery too, just to be safe. Otherwise, I really like the computer, wireless speed, wired cadence. My cadence has drastically improved since I started monitoring it.

Wireless are prone to this type of interference....hi-power radios, overhead wires, trams, mobile phones, trains etc etc

Yup... my Polar HRM watch will auto-start an exercise if I get too close to my PC monitor.

lol.....I can get to 232 bpm running around the lake opposite my office as I go under a mobile phone tower.
