DSL modem/cables

[revthomasd]

I have a DSL modem (Westell) in one room and I want to put the wireless router (Linksys) upstairs. This will keep sticky finger off the router, although it also makes my cable about 20' long. It's not working... When I put them together and use the supplied short cable, all is well. Am I encountering a latency issue with the longer cable or is the cable that came with the modem actually different than a standard patch cable?

My modem/router is a "normal" bridged modem and PPPoe setup on the router.

Thanks - RevThomas

There are two additional types of cabling that plugs into the DSL modem in addition to the DC power. You need to identify the cabling.

OK – let me try again to better define the problem.
First, this is the topology:
DSL (Bellsouth) > modem (Westell 2200) > wireless router (WRT150n) > hub > pc & server (both located in a secure area)

All other connections are wireless access only (normally 5). OS is XP Home & Pro. All get addresses from DHCP on the router (except the server). Due to the human traffic in the area where the modem is located, I want to move the router to a more secure location (upstairs).

The component affected is the CAT5 cable that normally goes from the modem WAN port to the router WAN port (it comes with the modem and/or router) – it is way too short. Whether I build a CAT5 cable (586b pinout) or use a purchased CAT5 cable, the result is the same: no internet. I can still ping the router (with wireless or wired pc’s), but cannot get online.

If I reset the modem and try to connect directly with only a laptop, all works well. If I use the supplied CAT5 between the modem (now set to bridged mode) and the router (use PPPoe and nothing else), I can access thru the router to the internet. When I replace the supplied CAT5 with a longer one, I no longer have internet access.

My conclusion was that the cable presented the problem because of the length. Is it possible that I incur enough latency with a longer cable to disrupt modem-router communications? I’ve not run into this before and need HELP!:confused:

This is not a latency issue when dealing with less than 300 feet in this case. It is probably an interference issue, which the second quoted thread covers. Another option would be to consider relocating your DSL modem closer to the location you want.

Thank you very much for the reply and direction! - T

It wouldn't hurt to share your outcome with these forums when you come to a working conclusion on this situation.

Has the second quoted thread been looked at prior to modifying the configuration as described in thread - http://forums.practicallynetworked.com/showthread.php?goto=newpost&t=8293?
