I have a RV082 connected to two cable modems (12000/1000) from the same cable isp w/ the latest firmware. The cmts my isp uses is from ARRIS. When I connect both modems the ping result (exp: www.heise.de) drops to ~50%, if I disconnect one modem the ping result is at 100%. When I use my pfSense router (ALIX board) on both modems all works fine. The only thing I noticed that both gateways from the cable isp have the same mac addresse. bye!
