RV082- Performance & Stability

I have an RV082 with DHCP 6Mb cable modem on WAN1 and 3Mb PPOE DSL on WAN2. When WAN1 (cable modem) is active, after a random period of time, the router will become very slow and then finally quit routing all traffic. A router restart clears this issue for another random period of time. When WAN2 (DSL) is active, the router does not have any issues and never experiences this issue (I reboot quarterly anyway which may be masking the issue). This issue has persisted since I purchased the router when it was initially released and has been an issue for all releases of software and switching WAN ports around does not make a difference. Although the simple answer is to just use the DSL connection, that is not desireable as it is slower and is really intended to be there only as a backup.

Another problem with this router is that the SmartLink backup option of using one WAN port as the primary and the other as the backup really does not fail over automatically. I have played with every setting and never been able to get the router to recognize a connection issue with a WAN except for when the WAN cable is disconnected. Only then will an automatic failover occur.

In addition, I have noticed that on my cable modem, I have only been able to get a maximum throughput of up to 4Mb with the router and a full 6+Mb without. The DSL always gets a full 3Mb throughput. I finally found that leaving the MTU at Auto was the problem on this one. Setting the MTU at 1500 has brought the speed tests up to and above 6Mb consistently.

what firmware are you using?

please note: ALL RV0XX units have MTU set to Auto

Auto = 576

Yeah

MTU to 1500

Make sure MTU is set Manually

1500 for Cablemodems

1492 or lower for PPPoE / ADSL

Re: RV082- Performance & Stability

In an effort to relieve the RV082 of some of it's traffic, I installed an WRT54G between the WAN2 of the RV082 and the DSL modem. I then moved my 2 Vonage and 1 VoiceWing VoIP lines onto the WRT54G in a separate VLAN with priority. This vastly improved performance on the VoIP lines and had little to no impact on the performance of the RV082.

Then, with the MTU set at 1500 on the RV082, I ran a ping -l test on both WAN ports to find the port with the lowest maximum MTU. I found that the WAN1 (cable modem) had a maximum packet size of 1472 and the WAN2 (WRT54G/DSL) maxed out at 1492. I set the RV082 to an MTU of 1472. This improved speed on the cable modem bringing speedtests on WAN1 (cable modem) up to 7063 Mb/sec and the (WRT54G/DSL)up to 4000 Mb/sec.

Now, getting back to my original issue of slowness/freezes! I am now experiencing the problem more frequently (daily) and have observed that although the issue impacts http & ping type apps, it does not appear to impact email until the router freezes and becomes un-responsive.

So, yesterday, I took all devices/computers off of the RV082 and moved them to the WRT54G. I then periodically have booted up a computer onto the RV082(brand new Dell laptop) to test the WAN connections and then shut it down. I found a short while ago that the RV082 was very slow to respond, could not ping any sites nor browse any websites. I proceeded to reboot the cable modem and tested with no improvement. I then made WAN2 (WRT54G/DSL) active and had same problem. Rebooted the DSL and the WRT54G without any improvement. I then performed a restart on the RV082 that cleared the issue.

Somehow, I don't think I am moving forward here ;-)

Re: RV082- Performance & Stability

I also had stability issues with 1.3.2
After flashing back to 1.1.6.14 everything was back to normal.
People on other forums are reporting similar experiences.

Re: RV082- Performance & Stability

I have a RV082 with a cable router on Wan1 (static IP) and another Linksys router with DSL on Wan2 (static IP)

I have also never had SmartLink failover work. If anyone has, I'd be interested in hearing about it. If I knew that someone else had it working I'd try again.

Re: RV082- Performance & Stability

I just upgraded to 1.3.3.4 beta and still have all of the same problems. Any idea where I can find 1.1.6.14 firmware?

Re: RV082- Performance & Stability

I also tried smartlink failover on version 1.3.3.4 and I was not able to get the failover to work correctly. Not only did it not fail over, but it exasperated my other issues. I put back to WAN1 as priority and at least it doesn't stop responding as often.

Re: RV082- Performance & Stability

try their ftp site where their old firmwares are
