bandwidth being stolen?

post #1 of 20
Thread Starter 
What's going on here? My cable modem and router send/receive data lights are always flashing even if all my network devices are turned off.

I have

Cable Modem---->Router------Wired XBOX 360 and PC

Wireless Desktop and Laptop

-----------

MAC ADDRESS FITERING ON

(Only devices with these MAC address can connect wirelessly (Deaktop and Laptop)






WPA Encryption so even if MAC is spoofed people don't know key



----

sometimes I have seen something without an IP address present itself in attatched devices...how when thats only things that are wired to router (PC and 360)

yet my lights flash all the time is my bandwidth being jacked?

yes my router login pass is changed

See what your getting.

Also disconnect your Xbox 360 when testing, and only leave the laptop in.

Does your router have an option for logging connections, or viewing a connected clients table (could also be under DHCP table)? You should be able to see exactly what is being sent from where if you have an option for logging, and looking under DHCP/client table will show you if there are any intruders on the network (the DHCP/client table will show all of the IP addresses that the router has assigned, if there are any that don't belong to you, you might have a neighbour spoofing your MAC address). Also, sometimes modems (specifically DSL) play a "keep active" game, where they send a ping every couple of seconds to the ISP to remain connected. There is also the possibility of a malicious individual (or individuals) pinging you or port scanning you for vulnerabilities, but for it to be consistently flashing, it seems unlikely.

just change your network security to Wpa2 and no one will be able to bypass that *realistically* without breaking into your house and physically plugging in they computer

You can't really determine if it's bad from the light blinking constantly, there is (as far as I know) no way to determine how much bandwidth is being used from a blinking light on the modem. You would need to have some idea of the cause of the blinking light first. Try disconnecting ALL devices from the router, see if the modem and the router still blink. If they still do blink, try removing the router temporarily. Note any noticeable changes in blink speed. If, with just the modem connected to the outside line, it still blinks constantly, you may want to contact your ISP and ask them to run a diagnostic, or just voice your concerns to them.

If the lights stop blinking after you unplug the devices, start plugging them back in until you find the culprit. Once you have him in your grasp, you can figure out what is causing the constant packets and, if it is harmful, fix it.

If the modem stops blinking when the router is unplugged, try plugging the modem directly in to the components one at a time and without doing any internet activity on the components as you do this. If you find the culprit this way, and not with the router method, I would be stumped.

If you don't find the culprit and your router and modem still blink with everything disconnected, chances seem good that someone is jacking your bandwidth.
