Speed Issues with the RV320 Gigabit Dual WAN VPN Router

JDJaworski

I've set up multiple routers over the years by a handful of companies. If there was ever a problem, typically there was always as solution to be found on the internet. Never have I had so much trouble with a router that I've been forced to register on forums and seek support, but being at my wits-end, here I am.

 

Background:

Boss wanted a new router for some reason, so I was tasked with setting it up. I set up the previous router without any issue. We were sitting on ~100 Mbps with the older router. After running through the setup and messing around with settings on the RV320, we were only able to get up to ~15 Mbps. None of the solutions online I found worked. There was one I didn't try that suggested adding switch between the modem and the router, but even if it did work, that really shouldn't be the solution to this.

 

Chances are I just missed a thing or 2 (there are a lot of settings), but at this point I don't even know where to look.

 

  • Old Router - Netgear R7000 Wireless Router
  • Modem - Not Sure (I can find out, but this shouldn't be an issue right? ISP is AT&T)
  • IP is static and I've entered all values used in the previous router for IP, Subnet, DNS1 & DNS2
  • SIP ALG disabled
  • Set to "Gateway"
  • I increased the downstream bandwith for WAN1 & 2 from 10,000 kb/s to 100,000 kb/s
  • Only using WAN 1
  • I tried disabling the firewall. Currently it's on as it didn't affect the speed.
  • Firmware is  v1.4.2.15 (most recent I believe)
  • Path of data is Internet > Modem > RV320 > My Computer. We have access points hooked up to the network, but for the sake of testing I have removed them to minimize the variables to account for.

As I said, at this point I really have no idea. Do I need to find a way to disable WAN2? I set it so that WAN1 was the default. Do I maybe need to set everything up on WAN2 and ignore 1?

Hello,

have you checked the MTU settings under 'WAN Connection Settings' ? Check page 22 of the attached user guide for instructions on how to change that (assuming that you have a PPPoE connection).

Even before you do that, send a ping with different sizes and the no fragment bit set to find out what the maximum is, e.g.:

ping 8.8.8.8 -f -l 1472

Sorry about the late reply. The only time I have a chance to work on this is outside of business hours so I don't disrupt the tenants.

 

I sent the ping as you wrote it and got:

  • Packets: Sent = 4, Received = 4, Lost = 0 (0% loss)
  • Average = 39 ms

As for whether it's a PPPoE connection or not, I don't believe it is. I did some reasearch on it, and while we have a static IP, we don't have a username, password or service name that you would need to enter if I used PPPoE as the "WAN Connection Type".

 

I've been using "Static IP" for the connection type. The MTU was on "auto" but I tried setting it to "manual" with a value of 1500. I can't say I noticed any difference however.
