wireless cctv system clashes with wireless router

leosayer39

Hi all,

As the title suggests I have just installed a wireless cctv system and the signal from the cameras to their receiver is being interfered with by the signal from my wireless router.

I am positive that the router is messing with the camera signals, because if I disconnect the router, the camera signals are perfect.

Anyway, back to my signal problems.....I believe there is a way to change the channel that the router uses to communicate with my lappy and pc. Ther is no facility to change the channel that the cameras use.

Can anyone help me here.

For your information my lappy and my pc are not networked together, they are linked seperately and wirelessly to the router. My lappy is the computer that has access to the router, the pc doesnt.

I hope that all of this makes sense.

Cheers

Leo

You should be able to log into your router and go to Wireless Settings then change the channel number. You could experiment to find a channel that does not clash. The PC/Laptop may need to search for the network once the channel has changed (right click on the little wireless icon bottom right View Wireless Networks)

Try channel A cctv and channel 11 router (or 13) or channel D and channel 1, it will probably still interfere, but not as much.

192.168.1.1 linksys

Thanks for that...

I have just logged into the router using the lappy and I changed the channel that the router was running on from channel 11 to channel 13...and then all hell broke loose

The lappy could no longer see the router and when requested to search for a wireless network it could only find the nearest one...which was my neighbours, and encrypted.

The lappy could not find my own wireless network at all!!

I then went to the pc, which as you may remember, doesnt have access to the router, and sure enough, it could access the router and I duly put the router channel back to channel 11.

My lappy can now see the router and is now connected to it wirelessley. I don't know how, but my pc also never lost sight of the router at all, and can now access the router (it couldn't before)

Initally, as you may have sussed out, my lappy was the puter that had 'trusted accesss' to the router. It looks as though when I changed the channel from channel 11 to channel 13, the lappy lost contact with the router and the pc automatically became in contact with the router. I have no idea how this happened as I did not give the pc trusted access.

I am back to square one. It's all very very confusing. Hmmmmmm

Any ideas please

Not really, you now know that 13 is no good (probably same or similar channel to a neighbour's wireless etc causing interference). That still leaves 11 other channels to try besides channel 11. You don't give up after only trying just one other channel.

Thanks for that, getting there...........I ll keep trying

Another question. as there are four cameras, does that take out 4 of the 13 channels available?
If it does, then my neighbours router wil take out another channel, making 8 channels available to me. Is this correct?

As an aside, i will give the pc 'trusted access' to the router' as well as the lappy, then if the lappy cant see the router then hopefully the pc can.

Not quite as simple as that, in fact I'm sure the cameras are all operating on the same channel. And yet the use of a particular channel can mean that a few of the channels either side are unusable depending on the strength etc. In the frequency range the channels aren't completely discrete but overlap with each other. In the end all that means is that you may as well try as many channels as possible (but start off with ones as far away as possible from the one you're having trouble with, e.g. channel 1).

Cheers, still contemplating......

Think I have go this 'trusted access' thing wrong.

'Trusted access' seems to mean that each puter with 'trusted access' has access to the internet via the router....and NOT as i originally thought, access to the settings within the router.

Originally my lappy alone could access the router....now the lappy and pc can access the router settings.

How do I make the lappy alone have access to the router?

Surely you just set a password so that only you can access the router's controls, regardless of which 'puter you use?

Thats true, but when the system was originally set up, (not by me) only the lappy had access to the router, using the appropriate user name and password.
The reason for this was that everyone in our house can use the pc, and only me can use the lappy.

Now, both the pc and the lappy have access to the router using the appropriate user and password.

I would like to get it back to the lappy alone having access to the router settings, not the pc.

If you change the router logon password then no-one else will be able to access the router controls from elsewhere, you can set your lappy to remember the pw so from then on only the lappy can access, in effect.
