Is MN-500 a switch or a hub?

Hi all

I have MN-500 and two wired PC and one wireless PC are connected to it.

By some reason, I believed MN-500 is a switch, not a hub but recently I
noticed that packets seemed to be sent to computers, which were not in that
communications. How did I notice? My computers have LCDs, which blink when
they have network traffic.

Software-wise, according to task manager's network traffic graph, they do
not receive any non-interested packets.

Is MN-500 a switch or a hub?


Thanks.

It is a bridge/switch/router. The router connects to the wireless &
Switch thus bridging wireless to Twisted pair and providing switch service.

Thank you for the reply.

Then I wonder why PCs not involved in the communication have network
traffic.

It could be one of several things.
1) You have persistent port forwarding set to a computer and information
is being sent on that port.
2) the computer is checking for updates with any of the programs you
have installed on your computer
3) it could be a virus trying to spread
4) it could be spyware or adware connecting to it's host

To check for I virus I recommend an online virus scan at
http://housecall.antivirus.com

For the spyware & adware I recommend both Spybot Search & Destroy and
ad-aware 6. Both are free downloads for home users. Update them after
the install and let them run a scan.

Thank you for the reply again. Let me explain my situation.

I have 3 computers, A, B and C. A and B are wired to MN-500 and C uses
wi-fi. When I copy files between A and C, B's network LED blinks and the
blinking synchronizes(!) to A's blinking. It seems to me MN-500 works like a
hub.

Since I have only 3 computers connected, I do not care much even if it is a
hub. :-)

I'm just curious. I wonder if MN-500 owners want to look at your PC's
network LED.

Thanks.

Try a soft reset on the router by unplugging it for 10 seconds &
plugging it back in. If that solves it then it was most likely the
table in the switch was corrupted & the soft reset cleared it.
