We have installed 24 port unmanageable switch of 3COM. And internet is coming through our Broadband wireless router.
So try to connect switch and router with straight cable. But it's not working. I also tried with Crossover but not succeed.
But when disconnect cable from switch and connect direct cable from pc to modem, internet work as well as wifi works.
But when i connect straight or crossover cable from switch to modem, internet is not working any where, not pc connected with switch, not on pc directly connected with router also not with wifi connected laptop.
I also changed cables with new one. and also tried with switch 1st port and 24th port.
Currently router is set as 4th port is connected with ISP internet ONT box from where internet coming. Then router have id & password of internet.. which distribute internet with other 3 port. This setup is done by our ISP only.
So why this happens? it looks like it doesn't have problem from ISP side? does it?
Is Router is faulty or switch?
What is proper way to connected router with switch? in which port to which port? by which cable?
Thanks in advance.
