RV016, internet randomly stops...large downloads impossible.

    For the sake of narrowing down this problem, assume all firewalls are off and I'm only running one WAN connection. Before changing over to this router (previous used win2k3 advance server's nat service) we very rarely if ever had a problem. Since I installed this one, it locks up about every minute or two when browsing around on the internet. Large downloads (well, anything over a meg) only gets to about 500kb then it stops and never starts again. I have the latest firmware and have connected directly to the cable modem and have NO problems then, so I have to suspect the router.

    Any ideas or suggestions??? Thanks.

    maybe worth noting, I just noticed I was getting knocked off of AIM very consistently... :(

    tech support says lower the MTU? Is this going to help?

    I am having a similar problem with the rv016 -- every so often it appears to reset or just reset the network. I have tried everything, one thing that I have found that makes it worse is to PPTP into the router. about every 10th pptp crashes / resets the routers. this is killing my client server app that can't handle the resets. any idea how to work around it.

    btw -- I have been using the rv016 for well over a year now. it is the worst router I have ever used. Full of bugs!! linksys support is useless for real questions. I would love a fix to this problem.

    Had the same problem. After fooling around forever, I called cox communications (my business's ISP) and asked them what the issue could be.

    It ended up being a conflict on their end, due to them using cisco equipment on their end that was conflicting with my RV016, for some reason.

    They cleaned up their backend MAC addresses and had me reboot the cable modem and router, and voila! fast internet.

    Hope that helps!

    Here's a usable answer: Try setting your MTU to 1350 and "Manual" as opposed to "Auto." The other option would be to download "Dr TCP" and set the MTU on your machines to 1350. Either one of these options may be of some help.

    Not knowing what has been fiddled with regarding the router, I'd try a factory reset, then set things up again.

    I have 3x of the RV016 routers out in service at clients...wonderful routers, I love them. 2 of them in rather larger networks that hammer them pretty hard too, getting the PPTP VPN used daily.

    I have noticed that the auto setting on MTU doens't work well, so I'm a firm believer in setting it manually. I've found this on any router brand..that auto-MTU is not perfect..so I always lock it down manually. 1492 for PPPoE DSL, 1500 for bridged DSL and cable.

    For laughs, sometimes auto-negotiation between the WAN port and the broadband modem doesn't work perfectly...can try plopping a hub or a switch in between just to see what happens. I haven't had to do that, but might be worth a try.
