  • Wrong cable
  • Different subnets
  • Firewall

How is it you know they don't have connectivity?

what do you mean by connectivity? they can all connect to the internet

my problem is with w7 and sharing folders within my home network, it was working fine before the switch was added

i dont think its firewall or cables.. if anything the subnet issue sounds very possible.. the pc's off the switch seem to be in it's own "subnet"

It assigns all ports to VLAN 1 and forwards the traffic to the router. If everything is connected in the router, the router will see that hey this needs to go to VLAN 2 or VLAN 3.

So to sum it up, does the switch support 802.1q tagging?

*EDIT*
try moving all pc's that hang off the switch to the same subnet. example
192.168.0.0 255.255.255.0

That should fix your issue.

ignore the wifi router, that might be a separate issue all together

what i mean by 2 separate networks is that , if i connect 2 pc's to the switch, they can see each other

but if i connect one to the switch, and one directly to the router/modem, they cant see each other

sorry for my lack of networking terminology, and by 'see each other', i mean if i share a folder in w7, the other pc cant see it

here is the link the to switch:

edit:

how do i move subnets? through my router ?

you guys are making this all so much more complicated then it should be.

connect up the wifi router to the modem, then the switch to the wifi router. ALL computer connect to the switch, and all wireless computer connect to the wireless signal. that will make all computer apart of the same network. a switch is a switch is a switch is a switch. simple. it doesn't matter how you connect them, they will work the same way, unless you are connection two switches together, in that case you can use either the uplink port or a cross over cable. the uplink port just simulates a crossover cable.

@bratas, sorry if that came across wrong, it is really hard to tell what you meant in the first post because you used two lines so it showed up weird in my email.

OP, no computer should be connected to the modem, that will act solely as a modem, not a router. all computers should be connected to the switch which is connect to the router.
if you have a setting in the modem to make it act as only a modem, that would be great, because then it will give an external IP address to the wifi router.

everybody else that is telling you all these complicated things to do with the network are wrong. that may work, but is completely unnecessary. just hook it up the way I showed you in the picture and it should work just fine, because then all the computer will be on the same subnet.

that's the thing though, it's an all-in-one modem/router/switch/etc.... i dont have a standalone modem, do i need one to make this work?

well then don't treat it as an all in one, use it like it was just a modem. so just act like it only has one network port and can't be used to connect anything but a router to it.

everything else should be all good to go once you get the router plugged in and the computer hooked up to that switch.

do you mean dont connect the switch and wifi to the all-in-one

just connect the wifi router, then connect the switch to that?

i.e. the wifi router should be the only thing connected to the all-in-one, besides the WAN?
post #17 of 27
You shouldnt have an issue with anything after the router. As others have said connect the modem to the wifi router, then everything else should be behind it. I have two routers a switch and 6 PC's plus smart phone etc on my network and have no issue. Just make sure the router connected to the modem is the DHCP server, and everything else has DHCP turned off.

EDIT: added my network map

connect the wifi router to the modem, and then connect the switch to the wifi router, and connect all the computers to the switch.

I should break out the visio.
or break out packet tracer.

Well, put it on the same subnet.

I had to google 802.1q tagging,some good articles. The Wikipedia article started out with "this article may be too difficult for many to understand......This was the first time I ever saw this line in a Wikipedia article.
