I own a RV042, with the firmware 188.8.131.52, if uploading at 10Mbit/s, with about 40~60 outgoing connection at the same time, the router will stop upload and stop responce for about 5 seconds with every 10~15 seconds. I had try to disable firewall, no VPN, no upnp, using DMZ, etc. but still didn't find a solutions. and this is not applicaiton specific. My current work around is to limit it not upload more then 300Kbit/s, or limit it to have below 30 upload connection at the same time. Anyone else have the same problem with me? The most interesting is download is ok, just upload have the problem.
