i went ahead and tested with a short store-bought cable and i got perfect throughput.
damn. all that for some badly terminated cable!

many thanks for all your help!! ]]> http://www.dslreports.com/forum/remark,21912840 Fri, 13 Feb 2009 17:13:24 EDT http://www.dslreports.com/forum/remark,21912676 dgilbert : but is teh PC conencting at 100mb FULL duplex? if not the cable could still be the problem.

one last thign it can be tha thas happened to me before is that BOTH devices support auto polarity sense. this messes with each other and they both keep flipping TX and RX pairs. if one has the optioin to turn this off, do it.

Do you get 80% packet loss with a new cable?

I've tried it with 2 different 2nd routers.
(I should add that I'm not an average end-user, I've been messing with networks for about 13 years now, not exactly professionally but in home and small business environments, dealing with everything from T1 circuits to ISDN lines to ADSL. I've almost never had as much trouble as with this situation.)

One weird thing I observed with my latest attempts is that once I got the 2nd router on the same subnet, connected to the 1st router via LAN ports, I could actually ping the 1st router from behind the 2nd, only with something like 80% packet loss. In fact I could ping out to the internet but also with 80 to 90 percent packet loss, and no http. And I can't ping the 2nd router from the Netopia (the Netopia has a little ping utility on it)

here's another possible clue: in the Netopia log there are entries like this:

00:00:15:20 LHD: Interface Eth 100BT, State offline
00:00:15:20 LHD: IP 192.168.0.2, MAC 00-0c-41-4f-f0-fe
00:00:15:19 LHD: Interface Eth 100BT, State suspect
00:00:15:19 LHD: IP 192.168.0.6, MAC 00-23-32-2f-52-f9
00:00:15:19 LHD: Interface Eth 100BT, State suspect
00:00:15:19 LHD: IP 192.168.0.2, MAC 00-0c-41-4f-f0-fe
00:00:11:45 LHD: Interface Eth 100BT, State online
00:00:11:45 LHD: IP 192.168.0.77, MAC 00-23-32-2f-52-f8

.77 is a host connected directly to the Netopia.
.2 is the 2nd router (connected via a LAN port).
.6 was the machine i was pinging from (connected to a port of the 2nd router).

What's the 'state suspect' business? Could the Netopia somehow be not "trusting" the connection from the 2nd router, for some reason? Or...?

It seems like this has to be some problem with the Netopia, because the same thing happens with 2 different 2nd routers a linksys and a netgear, and the linksys worked fine when i was using it behind a motorola cable modem.]]> http://www.dslreports.com/forum/remark,21912291 Fri, 13 Feb 2009 15:44:40 EDT http://www.dslreports.com/forum/remark,21910128 dgilbert : follow the steps in the FAQ given to you. your problem is tha tboth side of teh network for teh router are in teh same subnet. that does not work with NAT. for the least problems. you want the router's DHCP server turned off and hook it up as a switch/AP. if you use the internet port on the router, you have to use a different subnet for it's LAN side and you have to setup any port forwards in it as well as the netopia.

sorry but i think it has nothing to do with SSIDs and channels. even a computer wired to the 2nd router can't get out to the rest of the internet.]]> http://www.dslreports.com/forum/remark,21908703 Thu, 12 Feb 2009 22:20:57 EDT http://www.dslreports.com/forum/remark,21908240 jimbopalmer : You want the second router just to act as a Wireless Access Point?

»Wireless Networking Forum FAQ »Using a Wireless Router as an Access Point

Same SSID, different channels (1, 6 or 11) same Passcode in security.

I've tried 2 different routers to do this (a linksys and a netgear) and can't get either to work. I've tried letting them get dynamic IPs from the netopia, no luck. i've tried giving them static IPs on the netopia's LAN, no luck. nothing seems to work.

One dumb thing i'm afraid is the problem: do i need to use a crossover cable? If not then what is the problem? any ideas?

thanx.]]> http://www.dslreports.com/forum/remark,21908183 Thu, 12 Feb 2009 20:32:48 EDT
