Wifi signal jammer should not use for illegal purpose. If he keep on doing that, you can warn him. Or you can also buy a wifi signal jammer to block his wifi signals.

Things like phone jammer wifi blockerr can actually be beneficial. However, it is such as pity that there are some people out there use it with malicious or illegal intention, which make the product known as misuse.

What's the Make & Model and firmware version of the router? How many are clients are connected through WiFi?

Here's a few things you should know about wireless routers (If you don't know already)

WiFi channels

They work using a channel range much like the radio on your car. Have you ever started driving somewhere and two radio stations seem to mesh together? This is what happens when the station's frequency range mixes with another that's in range.

To keep it simple, your G/N router uses channels 1 - 11. Again I'm keeping it simple and not getting into the advanced settings for explanation. If you're on Channel 1, and your neighbor is on Channel 1, there will be interference and it'll become problematic as packets will start to drop and your net will become slow or in some case unusable.

You can go into your router, usually the URL is as the default route, and log into your router, change the channel and see what happens. The better channels are 1, 3, 6, 9 and 12. Do note that if you pick Channel 2 for example, you'll be using up some space on channel 1 and channel 3. Google/Youtube can be very helpful at explaining this better than I and the more advanced settings and how to narrow it down for maximum efficiency.

SSID Broadcast

Every router comes with an SSID Broadcast, which is what you see when you connect to your internet. "Connected to LinksysE3000" or whatever you named yours. You'll see this when you click on the wifi button on whatever you're using to connect to the internet. It'll display various wifi hotspots around.

You can disable the SSID Broadcast (usually in the wireless settings of the router) and your wifi signal won't come up in the connection list. Anyone that wants to connect to your router will have to know the SSID and to do that you'll need to use wireshark or something.

IMPORTANT: If you do disable the SSID Broadcast, you will need to KNOW exactly what it is, otherwise you won't be able to sign onto the internet.

Determining if it's a Jammer

You can determine this by getting a wifi application that monitors the wifi signals using your wireless card. You can download one of those applications for PC or get it for Android/iPhone. If all channels suddenly drop, that means they are most probably using a Jammer or the sun just shot a solar flare at your house. Logging this is important if you want to use legal action since Jammers are illegal.

REMEMBER TO CHANGE THE DEFAULT PASSWORD ON YOUR ROUTER'S LOGIN! If it's still linksys / admin, then you have to change that.

If I was you I would run CAT6 or powerline networking tomorrow to get your parents business back up. Document costs. The next day setup a honeypot network and catch those mofos. If they are jamming they might be attempting to hack also. I trust the instincts of the OP given his background. You need a wireless spectrum analyzer and a directional antenna to figure out where the attack is coming from. Get as much evidence and hire a lawyer.

Have you tried to set the wifi SID to not broadcast. They might not be sophisticated enough to go farther than straight wifi jamming.

A jammer like one you linked to in one of your replies would jam your computer from receiving any kind of wifi signal.. even if said signal was originating outside of the jamming zone. So all your devices would say "no network found" or similar.

In cases like this, where you can still detect network but not necessarily connect or receive good packets is to boot up a specialized network analysing OS such as backtrack, which (after disconnecting all your devices from your wif) can tell you if your network is receiving bad packets originating for elsewhere such as your neighbour.

That said, most likely culprit is a defective router, old or new, routers can easily become defective.

To troubleshoot, I think you need to turn off every appliance in your house including your mobile phones and such, except for your router and modem device. This way, you can know whether there are any inferences from your appliances. If not, it must be outside. Check whether you are near any high voltage source.

Try to reset your router to factory default setting. To do this, locate a tiny hole at the back or at the bottom of your router. Use a pin to reset it. You might have tinkered with the values that have caused a conflict in the configuration.

Hope this helps.

I was thinking about this problem.

Years ago I was into Ham Radio. Nothing big or fancy just a little DX-ing. It occurred to me that it should be possible to detect if you are being jammed using a frequency counter that covers the frequencies you need. All you would have to do is to start it up and keep it running close to your router. When the drop out happens turn the router off. If you attach a mini dish antenna (easily made) it would be easy to track the direction of the strongest frequency.

It also occurred to me that it may be possible to prevent attacks using a home built Faraday cage. If you make a box of mesh and leave one side only open you will only get signals from that side.

Just some thoughts.
