i just purchased a cisco 877 on ebay, when i got the router,, i connect to the LAN port,, but didn't get any ip from the router,, then i tried to hard-reset the router by press and hold the reset button on the back for a long time, but nothting happen, not sure if it reseted to the factory setting or not..then i try to connect to lan port again, still not getting an ip,, okay, then i try to manually config the ip to 10.10.10.5(also tried 10.0.0.5, 192.168.0-1.5) and try to connect to the router,, but still no luck, try to ping the router, no luck too, i tred to contact the seller,, he just said, the router is working for sure.. i must need an aux cable to program the router, LAN interface can't program the router, he doesn't want to refund my money,, i don't think that is true... does anyone know for sure cisco 877 allow LAN management on default settings???? thank you!!
