Latency issues, slow upload

[roscolo]

edit- I'm leaving this post intact, but read my update at the bottom. Problem appears to NOT be the RT-AC66U:

So I thought I was pretty much free from all the problems most seem to have with the RT-AC66U. For the last week or 2, I have been convinced that my DSL provider was not providing me with the speed I pay for (just running tests at speedtest.net) . Then I rebooted my RT-AC66U. Wow. There are the fast Ping results, Download, and Upload speeds I used to get with my old DIR-655!

With RT-AC66U, ping will go from 22ms, to 135ms, to 500-800ms. Have to reboot the router to restore the faster result. Download stays useful. I used to ALWAYS get 3mbps (maximum available here), but with RT-AC66U, looking at 1.1 - 3.1mbps download speeds. Unpredictable. To restore speed one must reboot. Upload speed, however, is the real killer. After reboot I will have the 650kbps I pay for. Within a few minutes, 100kbps - 400kbps. For several days I was getting 10kbps - 70kbps. That's dial-up speed.

Thought it was my ISP until the reboot. Wish I had caught this earlier. Too late to return now.

Using .354 Asus firmware. Have tried changing various settings too numerous to mention. The one consistent factor so far is only rebooting the router will restore the fastest settings. It seems to gradually go downhill from there until another reboot.

UPDATE:
I should delete this thread as THE RT-AC66U SEEMS NOT TO BE THE PROBLEM. Download Master seems to be the cause. I had read someone recommended not to install Download Master, but Asus Download Master is one of the primary reasons I purchased the router. Even though Download Master was not uploading / downloading anything, it seems to have been the source of the problem. I did not uninstall Download Master, I just disabled it. Thus far that has completely resolved the issue for me. Lightning fast again!

Disable Asus Download Master and PROBLEM SOLVED.

I guess I will just enable and use Download Master during times when no one is using the network, late at night, or when we're gone, which is probably the only times it is useful anyway.

related to comments in another thread - which wireless radio are you using? (the 2.4 or the 5Ghz)

.345 gives me great 5Ghz connections, but 2.4 are all over the place.

I have the exact same issue, i have given up on .354 and just went back to the released version .270)

I liked .354 cuz my Retina MacBook connected at 5Ghz all of the time. With .270 when it wakes from sleep it sometimes can't connect to the 5Ghz network (I believe that its a bug in the OS)

So now my Retina MacBook just connects to the 2.5Ghz network, and everything else that can uses the 5Ghz network.

Rebooting everyday was starting to suck.

Then again Asus did say that .354 was a Beta release.

I believe I was running into the exact same issues as you. Had the new firmware version and latency was a killer.

I went back down to the non-beta firmware and that solved the short-term latency issues, but performance would still degrade after a day and would require a restart.

Right now I'm just going to play the waiting game until a stable Asuswrt firmware comes out. I installed DD-WRT and never had another issue. I miss being able to register on Asus's private DNS server and the download tools, but hopefully I can switch back in one of the next revisions.

Can you post a link to the dd-wrt firmware?

So all is well that ends well!

Here's the April 15th build, I'm on the April 11th build.

There is a newer version out, but a lot of people have been reporting boot loops when trying to install so I'll just leave the April 15th build here for now.
