    The site is very interesting; please help me.

    My set up: Direcway 6000 ISP hooked to a WRT54g (no version after the model #); DHCP enabled; hard wired to two (2) computers; internet and printer services working thru LAN connection. The 54g is then hardwired into another building from a regular port on the 54g to a regular port on a WRT300n to service two (2) notebook computers wirelessly, for internet and printer services; DHCP is disabled on WRT300n. All computers are using the same SSID; all computers are set to automatically obtain IP addresses; 54g has IP address configured to and 330n IP address is configured to

    Problem: #1)The two notebook computers cannot connect to the internet or the printer. #2) I cannot access the 300n from the hard wired computers

    I have tried everything the Linksys people have asked on multiple occassions. I have tried everything the Direcway people have asked on multiple occassions. As of yet nothing has been successful.

    Is there a way to determine if my CAT 5 cable running between the 54g and the 300n is or is not a cross over cable? Does it need to be a cross over cable? If it has to be a cross over cable is there a work around, as the cable to buried in a pipe and runs about 500'?

    Thank you all in advance for any suggestions. I have been working with the help lines for over two months.[/I]

    If you get link lights on the two ports then the cable should be fine, also try disabling the firewall and upnp on the WRT300n if it has those options.

    500 feet? If that is true that is pushing it, theoretical max is 100m (about 330 ft). I have pushed signal on high quality cable close to 400 but still had a few occasional issues. The ports in question should be mdix, if they are you dont need a crossover. However if they are just mdi then you will need a crossover for the configuration you have. And it is as simple as re-terminating then end if that is the case. First order of business is to see if your laptops on the 300n can get an ip, either wirelessly or hard wired. I would go as far as getting a laptop and plugging the cable that goes from the wrt to the 300 direct into a laptop to see if the cable run is ok. If you get an ip on the laptop then the cable run is probably alright. I would then plug the cable into the wan port of the 300n and turn on dhcp making sure you have a different ip scope for the 300n then the wrt. If you have connectivity at that point (wireless clients as well), then terminate the cable as a crossover and all should be well.

    Let us know how it goes.

    Thank you for the information, I found the problem. One of the wireless notebooks has DHCP enabled under the 'wireless connection' properties. I have not been able to remove this, but I will contact the computer manufacturer to assist me.
