I have my wireless routing setup mounted in my garage to keep it out of site. The cable guy actually suggested it. It worked extremely well until I got the 911. Now, whenever my car is in the garage, I have no wireless signal, but as soon as I move it out if the garage, the signal is restored. Has anyone ever dealt with anything like this before or know what may be causing it? I am very interested to know what is going on.

Thanks.

 

Are you sure nothing else has changed - I'm not sure what emissions the car would put out to interfere. Some one reported a mysterious beeping earlier this week. He was sure it was the car but it turned out to be a battery low indicator in his sprinkler controller. Let us know if you find the problem.

 

cannot imagine that anything in/on/from the car is transmitting at the GHz required to interfere with a WiFi signal? WikiPedia says that:
Maybe it is just a higher power trying to get you away from the computer and into the drivers seat!

 

I doubt the car causes RF interference in the W-Fi spectrum region. The car (large metal box) may however affect the Wi-Fi antenna pattern. Reorient the router/antenna and see what happens.

 

Alternatively, you could do this simple test: Take your Porsche out of the garage, and put your wife's or neighbor car in the garage. It is quite likely you will see same problem.

 

I have a similar issue. I have a RF wireless remote which operates the alarm system in my house. Whenever I'm in my 11-year-old Toyota Camry it works flawlessly but when I use it in the 911 it doesn't turn off the alarm about the half the time.

I know that I could easily solve this issue by "cloning" my alarm system's wireless remote onto the Porsche's Homelink system but I don't want to do that. I'm concerned that if someone steals the car then they have the ability to turn off my house alarm system. The RF receiver on the alarm system isn't all that easy to disable so I rather play it safe than have the convenience.

P.S. I never "cloned' my garage door opening on the Porsche's Homelink system either for the same reason. Go ahead and call me paranoid, I'm fine with that.

I am pretty sure nothing else has changed. I haven't done anything with the garage, or house for that matter, other than buying the car.

leneuromancer:
I see what you are saying there, but isn't there something in the owner's manual about the car interfering with some gates and garage doors in some cases?
I am sure I could use some more driving time! Lol

Flying Cat:
I have done that test. Before I got the 911, I had a Cayenne in the garage, and it didn't cause any interference. Also, like I posted earlier, as soon as I take the car out of the garage, the wi-fi comes right back.

Thanks for the replies/ideas so far. I will keep checking into it. Hopefully I/we can figure this out without me having to move my setup.

 

Without giving away some security secret regarding wireless routers, could you tell me what the reason is for it being in the garage ? I'm scratching my head on that one. You can PM me if need be but others might be as interested in the answer as I am. As for the car causing interference is the car alarm armed when it's in the garage causing the problem ? I'm wondering if the motion detector in the car might emit a frequency that could interfer with the router. Sounds like a long shot to me though.

 

Dadio:
It's in the garage just because when the cable guy was here installing it, he suggested mounting it out there to keep it out of sight. No really significant reason.

Hmmmm, I wonder about the alarm. I'll check on that. Although, when the Cayenne was in there, it was always armed as well.

 

I know it's off topic, but it baffles me, too, why the cable guy recommended that you have the wireless WAP installed in the garage. If your garage is as insulated as mine, chances are you're losing 50% of its antenna coverage, if not more. It'd be better to install it in a central area, and as high up as possible.

 

Try disconnecting the car's battery - may seem a little extreme but it would eliminate the electrical interference possibility.

 

Well, it looks like it is directly related to the alarm. I did a simple experiment, which actually ended up being pretty cool and yielding some interesting results. I sat in my living room with my iPhone in one hand and my key fob in the other. I unlocked the car from my living room, and I could literally watch the 3G icon on the iPhone switch to the wireless icon. Then, when I locked it, the wireless icon switched back to the 3G icon. There was something pretty satisfying about hitting the button and watching the icon change almost immediately.

 

Cool. Maybe try arming twice quickly to kill the internal motion detector.

 

Thanks for the advice! I think the saga is finally over. I appreciate the help.

 

Actually... you should not lock your car and set on the alarm when your car is parked in YOUR garage, as you deplete the car battery. What is the point?

P.S. - I suspect your cable guy suggested mounting your Wi-Fi PoP in the garage to simplify the installation and make his life easier.
