Wireless router headaches (awesome photoshop work inside!! must L@@K)

[teddyFBI]

Why does my wireless router work when connected directly to my cable modem...but not when the input signal is coming via a big ethernet SWITCH.

I've posted about this before and couldn't get to the bottom of it, and I wanted to try tackling it again...but met failure [img]/images/graemlins/frown.gif[/img] ugh ugh ugh

Picture a standard cable modem. Well, when the outgoing wire goes from it directly into my wireless router, I'm able to configure my home wireless network just fine, and everything works.

HERE'S THE PROBLEM -- what I'm going for is a dual wired/wireless network...5 years ago, my parents had a big ethernet switch installed, and then threaded wires throughout my house...so i figured "oh, well since each one of those wires coming out of the switch carries an ethernet signal, I'll just take one and use it as the input to the wireless router and 'boom' wireless network enabled...after all, I reasoned, the wireless router doesn't know the difference between a signal coming directly from the cable modem, and one coming from the switch, right?

Well, apparently that's WRONG, b/c it works when the incoming ethernet signal comes straight from the cable modem, but NOT when it comes from one of the output ethernet wires from the switch. When I try the latter, the router successfully CREATES the wireless networ, and all my laptops can "see" it and appear to be exchanging data packets with it, but cannot connect to the internet

i'm somewhat tech savvy, and i've spent at least 8 hours of my life on this to no avail.
Help.

I made a pictorial display of this -- please don't allow my superior photoshop skills to have been employed in vain

How is the WR getting it's IP address and DNS number when hooked to the switch? You may need to write down what it is getting when plugged into the CM and then hard code those values into it when hooked to the switch.

OK, i think i see what you're getting at...where do i see what those values are (when it's connected to the CM)? And what are the specific values that I'm looking for?

This should work if you put a crossover cable between the router and the switch. As an alternative, if the switch has an uplink port, use it with the cable you have now. I'm assuming the cable between the router and switch is currently a straight through cable.

Teddy -

Don't connect the cable to the "Uplink" or "Internet" port on your switch. Just plug it into like Port 4. The cable coming out of the Wireless Router should also just be coming out of a wired port. The only time you should use the "uplink" or "internet" port is when a feed is coming directly out of a modem. It should work fine.
If it doesn't let me know.

I'm no expert, but I think you might need a crossover cable going from your switch to your router.

Also can't you just use the wired router ports to connect your computers via ethernet? Or are their more than you have ports or something?

Do you really need the switch?
I just plug one PC into the router while the rest of the comps/laptop connect vias wireless to the router.
