The CD led on my 876 configured router flashes slowly and doesn't connect to the ISP although configuration and IOS seems ok.
Software: I already tried several IOS versions (c870-adventerprisek9-mz.124 series). Tried format flash and loaded new IOS on Rommon. Tried different Rommon files (C870_RM_ALT.srec.123-8r.YI6 and Y13)
I tried with CCP configuration and tested. Testreport in CCP says check wiring and connection. I can't see any irregularities there.
Hardware: I tried a different memorycard.
In initialising/ boot up all leds seem to function normally. After startup CD led doesn't burn untill configure interface up up. Then it flashes but to slowly in comparrison with a functioning same router. After connecting the adsl cable flashing stays in to slow rithmus and does not start to burn constantly as does the comparison router.
The second same router which I also tested with same IOS and running configs shows a circa 3 times faster flashing of the green CD led and connects on the same cable as normal with connection and constantly led lighting after connect with ISP.
Can someone please tell me what the problem could be. Please don't blame me if I forgot to give some relevant information I'm not a professional, just an interested Cisco amateur.
Thanks in advance for your appreciated help,
Then definately hardware is faulty.
Rasing the RMA is your solution then... :-)
Don't Forget to rate if you find information helpful.
Number of possible causes exists.
1. Is PSTN lin plugged into router working fine.
2. Router port might be faulty.
3. Issue can b also with the authentication.
Can u paste output of following commands and debugs:
sh dsl interface atm
debug dialer ( If you have created one)
debug ppp authentication and debug ppp negotiation
