| Linksys WVC80N camera killing my network I have a Linksys IP camera and I can't for the life of me figure out what is going on with it.
I bought it when my house was empty, I had it connected to a DSL modem wirelessly and it would send pictures when there was motion in the driveway.
After we moved in, I kept it runnig for a while, no issues including after the switch to FIOS.
I stopped using it for a while, and then went back to it a year ago, after using it for a day or two I realized that I had connection problems in the house--laptops would not stay connected to wireless network.
After some troubleshooting by removing devices I realized it was the camera, I turned it off and didn't use it for months.
Some moths later I decided to hook it up again... remembering the previous problems I decided to use the wired ethernet port on the camera instead. Amazingly I still had problems with wireless network, even though the Wifi was turned off on the camera.
Had anyone experienced anything similar with this camera? As of now it's basically useless to me because it causes disruption with the rest of the network.
I have reset it to factory defaults BTW, so there should be no offending settings. I even tried to connect it to a different router (chained to my primary router) thinking maybe it was polluting the LAN somehow with broadcasts, but it still disrupts the wifi. |

Reading, MA | I should have mentioned--but there is no firmware update on their site, I'm at the latest version. |

Maybe the camera has been taken over by a hacker? |

I doubt it. Even if they had, not sure why it would affect my local network. Plus, they would have had to have hacked into my local network (behind a FIOS provided router), then into the camera which is PW protected, and ultimately loaded a custom firmware because I've done a factory reset on the thing multiple times.
...on top of this, I doubt they're as interested in what animal is living in the small hole in my backyard as I am  |

You say the wireless is turned off on the camera, but it is still causing a problem for you wireless network. That doesn't seem to add up. So, when the wireless is 'On' with the camera, you can see the SSID on your laptop when you have it search for wireless networks near by??
Then when the camera wireless is 'Off' you can no longer see the SSID of the camera on your laptop??
Ok, try this... Have the camera hooked up, and you thinking the wireless is off on the camera, but you are still having the problem with network... then take the antenna off the camera. It is best to test this with the camera maybe 75 to 100' from your router and laptop. Do you still have the problem now??

Hi,
That's correct--the camera is setup to use the ethernet port (there isn't a specific way to turn the wifi part off, it's just assumed to be off when ethernet is detected and used I suppose).
My router shows a little icon to indicate whether devices are connected via wired, or wireless. When I check my router, the camera shows up as being present on the wired side of the network and not on the wireless.
The camera itself doesn't have an SSID, it is a client that joins my local wireless network.
The laptop never fails to see my local wifi network, it will connect, get an IP, but simply not work properly (can't go to internet for example, but may be able to go to the router home page).
The camera itself has a private IP on my same subset, example 192.168.1.x ... and it's not duplicate of any other device.
One thing I have never tried is whether a PC on my wired network connects or not. I'm going to guess that it DOES because I had a PC streaming a local radio feed, if that were to go down I would receive an email and a txt, and I never did...
The camera's wifi antenna is built into the device itself, so I can't really remove it. I know that I was having wifi issues even with my laptop within 10' of the router, and at that point they are ~25' linear feet from where the camera was and separated by multiple walls (and the floor between basement and first floor).
I think you could be on to something though--I was looking at this from the perspective of how the camera was screwing up my network, but evidence I already have says that's not it--the wired PC kept working (apparently), the problem persisted even w/ the camera connected to another router. I guess I will open the case tonight and see if I can disconnect the camera's wifi antenna at the board to see the problem goes away. I should look at this as an issue of the camera interfering with my wifi network. |

the camera's address
the router's address
one of the DNS addresses that your router received from your ISP
what this will do is determine if (or where) packets are being dropped that would cause general connectivity problems. id recommend doing a continuous ping as well as increasing the packet size from the default amount, just to get a good sample size.
said by bemis:The camera itself has a private IP on my same subset, example 192.168.1.x ... and it's not duplicate of any other device. whoa, watch out with the term "private ip". in real life, "private" only means that an address not a publicly routable; that's ALL. a DCHP server can EASILY give out an address that you assigned "statically" if that address appears in the DHCP pool and you didn't create a reservation on the DHCP server. this could lead to a conflict.
anyway, before you open the case up, check the IP settings on your wireless devices. check your arp table (arp -a) to make sure that your wireless device isn't being told that the IP for one device is actually the IP for another. |

Thanks for responding to my efforts.
Another thing you might want to try, along the thinking of ABM is to assign a static IP to your laptop way in the middle of the subset. Then you can be sure the DHCP has not assigned that IP and see what happens.
Example: in 192.168.1.XXX, use 192.168.1.67 There is noway you have 67 devices on your network. See if the laptop will work with the camera on with the laptop being assigned that obscure IP.

kudos:1 | I'm not familiar with that camera but perhaps the wireless and wired ports are being bridged creating a loop, AKA a quantum packet accelerator. I've made that mistake before with a wireless ethernet converter.
