Bad hardware or software issue?

[jtolar]

I recently purchased a AC68p and installed AsusWRT immediately... Absolutely in love with the feature set and wireless strength. This little beauty is replacing my Cisco 2851 and a little linksys ap.

We recently moved and I had a 18/2 Mb dsl but they came out yesterday to upgrade to the 75/8 Mb connection. They gave me a Arris NVG589 gateway and I enabled IP Passthrough. I disabled all the filtering on the NVG589 and the AC68 is getting the outside ip just fine. The problem is that I am only getting 15-20mb from the AC68. I have one media server directly attached to the AC68 via ethernet. I have that server routed through a openvpn client connection to PIA everything else goes through wan.

When I connect directly to the gateway via ethernet on my laptop I am getting 75-82 Mbps. Connecting to the AC68 via ethernet and running the same test I get about 7-15 Mbps.

Here are a few things I did to test.

1. Connect laptop directly to port on gateway (same port I use for wan to the asus as to rule out a bad port). Run speed test 75-82mbps.

2. Connect server directly to port on gateway. Run speed test 70-75mbps.

3. Connect laptop directly to port on AC68 and run speed test. 7-15mbps.

4. repeat #3 on all ports on the asus. same result.

so I have almost ruled out the gateway. I have not hooked my old Cisco 2851 as it is a beast to configure sometimes. I have had this router for a little over 2 weeks so I can take it back and exchange it if i need to, but wanted to make sure I did everything to make sure it was bad before I did that.

Any suggestions?

My RT-N66U has a lot of nice features and RMerlin's firmware always seems to make the most of them.

I was however left with the need to use reboot scripts to keep the connectivity and wan->lan performance consistent.

In order to end the spurious performance I have tried been running an edgerouter lite 3 as my gateway device and configured the rt-n66u to be an access point.

Both are doing their jobs fabulously now. The rt-n66u still has a lot of usable features in AP mode and no longer needs scheduled rebooting to perform consistently. I was also able to move the rt-n66u to a more central location in the house.

If I knew then what I know now, I would have started with a wired only gateway and Access Point combo.

Cheers

I have the same router on ATT with not as fast dsl as yours, but have not suffered any degradation in speed. Make sure when you are in IP Passthrough that you have assigned your routers mac address to the router and that you are connecting to your routers wan port. The other thing to try would be to test without using the ip pass-through mode in the nvg589...that's how the tech initially hooked up my router, but I wanted my router to have the same up as the wan, so I configured it in ip pass through mode.

Any suggestions?

Make sure you didn't configure QoS for your old connection (in which case it means you had entered your old speeds on the QoS configuration page).

Also try doing a complete power cycle of your modem if you haven't done so: turn it off for 5-10 minutes, then turn it back on. This is necessary with some providers when moving to a different router.

Any suggestions?

Make sure that the MAC address field on the WAN setup page is blank (next to the MAC Clone button), and click Apply.

If it's already blank, or doesn't improve things...
Turn both the gateway and router off for about 15 minutes (reset things at the ISP end). Turn on the gateway and let it boot then power up the router.

Thanks for all the replies... looking at the setup I noticed that HW acceleration wasn't enabled. I tuned the router over lunch and disabled IPTraffic (which I think was one issue) and now things are working much better.

I ssh'ed into the router and ran a speed test and was getting 73 Mbps download. I then ssh'ed into my server and ran two speed tests. One not going through the vpn and one through the vpn. Non-vpn traffic is now at 67 Mbps and vpn is 18Mbps or better.

Thanks, Again... Now to figure out why I can't route plex on that server over the wan... but I will put that in another thread later.
