I had an issue today where an AP11D in router mode would not obtain an IP address from the ISP when connected directly to a cable modem. A PC or another router could obtain an IP without issue and the AP would also obtain an IP from the existing router without issue.
Any ideas? Are there known problems with DHCP client functionality in certain environments?
One of the negatives about the easy to understand/manage solution is if or when something goes wrong there are no tools to aid troubleshooting an issue like this unless I'm missing something. It would be nice if there was a way advanced users could access a console to help identify certain issues.
