I have UPC internet connection (chello.pl).
My router is D-Link DIR-300.
When I use provided modem to connect to the internet there is no problem.
When I try to do it via router, I can't get a connection.
I can log in to router and change its settings but the router does not "see" the internet.
I set connection type to dynamic IP address (DHCP).
In diagnostic mode on WAN cable I get:
TxPair Short Cable at 15 meters
(note: no longer an issue)
RxPair Error at 15 meters
How can I establish a proper connection?
EDIT:
ISP -----[concentric cable]----- modem -----[ethernet cable]----- PC (that works)
ISP -----[concentric cable]----- modem -----[ethernet cable]----- router -----[ethernet cable or wifi]----- PC (that doesn't work)
My modem is Scientific Atlanta model EPC2203 Cable Modem/EMTA.
ipconfig /all
while connected without router (sorry it's not in English)

Status when connected via modem:
You say
RxPair Error at 15 meters (note: no longer an issue)
- How did you solve this, that it is no issue any more? We have the same problem, and it still is the issue, that the connection via cable is quite unstable and we still get this messageTxPair Short Cable at meters
(whithout amount of meters!) – rubo77 – 2014-08-28T20:44:09.5432If you want to use your router ( I assume you mean modem ) your going to have to spoof the MAC address of the provided modem. – Ramhound – 2012-01-05T15:35:54.080
I meant both. I have a modem provided by ISP and my own wireless router (D-Link DIR-300). I connect this modem to concentric cable and then my router to the modem via ethernet cable. – Jan Ajan – 2012-01-05T15:37:46.130
1Have you tried a different cable between modem and router? – RedGrittyBrick – 2012-01-05T15:54:03.853
Yes I tried. Didn't help. Those cables worked very well in scenario without router. But why both cables get
TxPair Short Cable
andRxPair Error
? – Jan Ajan – 2012-01-05T15:55:16.010Did you make the cables? – horatio – 2012-01-05T16:13:59.530
Is your modem a DSL modem? – Excellll – 2012-01-05T20:13:35.993
I didn't make the cables. That is not important now. I'm not getting TxPair errors anymore. My modem is Scientific Atlanta model EPC2203 Cable Modem/EMTA. I did everything you suggested. I changet speed from auto to 100 or 10 Mbps. I restarted modem and router several times. I set router's MAC to one used previously on my PC. Nothing helped. – Jan Ajan – 2012-01-06T12:10:57.930
