New n66u, works great, slows way down, reboot,works great...

[Sisquoc15]

Just got a n66u. Firm is 3.0.0.4.274. Hooked it up to a centurylink dsl modem using provided Ethernet cable. Disabled wireless on the dsl modem/router. Worked great. Nice ping in speed test, about 40, and same wireless throughput as wired connection on the ipad, android phone and laptop. Several times during the day it gets slow. Ping goes to 900ish and bandwidth drops by about 90 percent, regardless of location in the house. If I reboot the router in the router menu, it fixes it and Ping and bandwidth return to normal on all devices. Checked the traffic monitor to make sure there wasn't anything else using the router during the speed tests.

Except doing the setup wizard, everything is default. I have both bands set up to the same ssid.

Any ideas?

Thanks!

Hi,

My only idea is to upgrade to the latest (stable!) firmware - best would be Merlin's version - download instruction from here.
After the update do a NRAM reset to get the default values from the new firmware - details here - and reconfigue the router manually (no restore of settings!)

And then wait and see...

With kind regards
Joe

I experienced a similar problem several months ago with the N66U as well. I had tried other revisions of the official ASUS firmware as well, .2xx and .3xx, they all exhibited the same problem.

I never really found a solution to my problem, I just repurposed the N66U into a dedicated AP and put my N56U with Padavan custom firm as my front end router and there have been zero problems since .

I haven't tried the latest 3.0.0.4.374_257 firmware or Merlin's .31 stable build with the N66U as the front router. Probably will give it a shot in the coming week.

When your router starts to slow down, plug a computer up via LAN cable, do you still get slow speeds? Maybe not related, but when my problem was happening, I noticed the "System Log" tab was generating a bunch of repetitive log lines for hours and hours. Check yours, see if anything if being extraneously generated. Especially if the router is idle and you aren't doing anything with it.

If anything, try joegreat's suggestion and don't forget to reset NRAM.

Just registered to reply. I too have experienced the same problem, though I noticed that it usually happens when I play the game, TERA. Ping reaches 200+ ms and stays like that between all connected clients (to the router) until a reboot. After which, everything is fine. Happened on stock and latest firmware. I have tried restoring to factory settings, that was good for a day or two, although I wasn't doing much with the router at the time.

I have the exact same problem on my n56-router. I'm running the latest Asus wrt firmware. From time to time the wireless speed gets so slow that the connection gets ruined out. Don't know what to do:/
