Read and let me know if you need more info. I will provide if I am able to. Linksys E2500 v3 (new out of the box) running TomatoUSB constantly disconnects and reconnects at varying intervals. Modem: Netgear CM400 I have used 3 different routers. The first two for connecting to ensure nothing is wrong with any cabling, NIC or my computer. I have used wired and wireless from my computer. Router(s): 1) Asus RT-N53 running running DD-WRT firmware no issues with connectivity. No MAC's have been entered. All IP's are DHCP. No issues connecting. I also bound MAC's with IP's and have no connectivity issues. 2) Linksys EA-6350 v2 running latest stock firmware from Linksys. MAC's are bound to IP addresses. No issues connecting. Factory reset and No MAC's have been bound to IP's. No connectivity issues. 3) Linksys E2500 v3 running TomatoUSB. Constantly disconnects and reconnects at varying intervals. Disconnectivity and connectivity times vary 10-30 seconds. I have tried binding MAC with IP's and not binding them using DHCP. Once I am able to connect I more often than not get this message. I presume it's because the packets drop or are not finding the router or being returned. When connecting to the routers GUI interface I will get this message: ERROR - 504 The Graphical user interface was unable to communicate with the router! These issues usually occur when a file is missing, web handler is busy or the connection to router is unavailable. Refreshing browser window might help.
