Flashing the Standard version of the Tomato firmware onto my Cisco E2000 went smoothly. I restarted the router, setup my network using the web interface and all was well. However, after the router has been on for approx. 20 minutes or so, the web interface (or even Telnet) does not reply… oddly enough, the wireless network and LAN jacks (WAN is disabled as a 5th LAN port) continue to work.
In using Wireshark on my PC to get some clues on what might be an issue, I noticed that when any browser I use attempts to communicate with the router, the ethernet ARP request goes out for my router, but my router never responds to the ARP request. This would explain why no management interfaces seem to work.
Any ideas what might be wrong here? I've tried re-flashing the firmware incase something went wrong using the (forgive my lack of knowing this methods actual name) method where you can quickly TFTP an image onto the device at boot. It successfully took, I re-setup my router via the web interface (192.168.1.1) changed the router IP and network settings, re-logged into the router later (now 192.168.0.200) but if you wait about 20 minutes… no ARP… no web… no telnet…
edit: Yes, my subnet is 255.255.255.0 — and the issue exists with all other network hardware removed (just laptop and router) and network settings are correct. Keep in mind, it DOES work for awhile, so it isn't network settings. Just wanted to clarify. Thanks in advance!
edit: Actually, found out if you wait just a little longer, no communication on any ports (eth or wireless) work. So the router just does nothing (despite all lights on the front-top looking normal). Also, logs after a reboot are empty for that time period (yes, time is correct).
