This seems to far complicated to resolve on a forum, Can you ping the router, does the router have the proper isp settings? Can you ping an internet ip address? Is there a problem with your isp?
It might be, but I have found that discussing something like this helps figure out solutions.
I have checked all the cat 5 cables from the desktops to the switch. Cables are good. The router loads on one computer but this is a side issue. Main problem is that the router is not loading DHCP or Static IP to finish connecting the Internet.
ISP declares everything is good through to the switch. Have older Cisco Switch dispersing 2-T1 lines into the building. Problem seems to be here as the port is intermittently working. Tried changing ports to no avail.
Your thoughts are appreciated.
