I recently switched to a Netgear WNDR3700 (v2) running DD-WRT v24-sp2 (02/19/11) std. It's basically working fine and I'm generally happy with it, but any tools that query the router via SNMP show all the interfaces as being 10 mbit. In fact, the LAN interfaces are gigabit, and the wireless interface is 54 mbit (or thereabouts).
This isn't a huge deal, except that when I try to set up alarms based on current interface use being over a certain percentage of maximum, I run into problems.
I'm unable to find anywhere in the DD-WRT interface to specify interface limits. Where does the router's SNMP service get this information? I'm able to access DD-WRT via SSH command line, so I'm wondering about the possibility of using Linux commands or configuration files to set the limits correctly. Is that even possible?
