ASUS RT-N66U - Wireless Usage Locks Up Router?

[DR9]

Hello,

I've been following this forum for awhile and upgraded to the ASUS 66u router and its great but 1 major thing for me.

I have a Motorla NV510 Router/Modem for my DSL from ATT&T.
- Wireless mode is OFF
- IPv6 is OFF
- IP Passthru setup on NV510
- IP range is 192.16.8.1.xxx and ASUS range is 192.168.2.xxx (no double NATing)

Wire plugged in from the mode to WAN on ASUS, configured the ASUS and Internet works fine via wired.

ASUS is on .108 firmware

I have no issues wired but wireless it's horrible and see if I can explain it.

My laptop (2011 Viao) is 2' from the router
My Xbox/PS3/HTPC are 12' away thru 1 wall

I get 100% strength on all the devices. I go to download a file and in about 2 minutes it dies and I lost Internet/LAN connection everywhere and have to reboot the ASUS router but using the power switch,

If I copy a file from my main PC to the laptop by wireless it will also lockup and I have to reset the ASUS.

I found thing blog about the NV150 which I think is the issue but not sure, I know it can't be the ASUS.

Something about the NV510 bridging. I hope someone can help me because stringing wires to my HTPC is not a long term option I want.

Thanks!

Hi,
Can you see any clue from the router syslog? Does it happen on both radio bands? Can you access the modem router with web address? Your ISP?
I am on cable and first thing when I hook up the ASUS router, I had to call
my ISP to ask firmware download to make their router into bridge mode. since
I am unable to access their router for whatever they did. Every thing been working just fine. I believe they downloaded non-stock special f/w for bridge mode.

Can you pls enable telnet on the router, keep a telnet window open from one of your wired computers, see if you can run dmesg and if you see any kernel oops can you pls post it on this thread.

Here is the command output on the wired connection to my MainPC to ASUS.

Yes I can view the web GUi of the NVG510 via 192.168.1.254 and ASUS via 192.168.2.1 no problems.

ASUS is .108 firmware and NVG510 is 9.0.6h0d48


Edit Notes:

I removed the NVG510 from the WAN port from the ASUS so now the ASUS is just a network for files no internet. I transferred a very large file to see if it would bomb again or complete and after about 1 minute it locked up again and I had to power cycle the ASUS.

So it is not a issue with the modem/router NVG510. I have all factory settings for the 2.4Ghz band and changed various freq's and channels and still the same result. I have one neighbor with a 2.4ghz wireless router in the area but is 50% strength to me and channel 11 i think. I put everything back to auto now and still same results.

Again this is a brand new flashed router bought about 3 days ago.

Hi,
I am sure you erase nvram any time you change settings? AC adapter should be checked as well. Still not 100% radios are are acting up. Is
the router getting hot to touch? Mine runs luke warm.

 

[DR9]

It's not overly hot about the same as my D-Link, just warm.

I've done that originally and assumed NVG510 was the cause.

In my update post above I removed the NVG510 from the ASUS router completely (no internet, unplugged WAN cable) and just used the ASUS to share network drives etc... Same issue persists, after about 1-2minutes of normal usage via wireless it dies and the ASUS is frozen/locked up and I have to power cycle it to get it working again.

Ok I did some more stuff which in the end resulted in the same problem.

- I tried upping n downing the power to radios
- System restored and re-config form factory
- Re flashing .108 again
- Hooked my old D-Link wireless back and everything worked fine

- I then flashed the ASUS with Tomato tomato-K26USB-1.28.RT-N5x-MIPSR2-087V-Mega-VPN

Things seemed to work a lot better until about 30 minutes later and it did the same again, ASUS router locked up and I had to power cycle it.

Anyone else have any ideas, I'm thinking hardware problem the router is B1 revision. Return this and buy from newegg or something.

Your router's kernel doesn't seem to record any hardware issues. I do recommend a 30-30-30 reset to clear out the NVRAM. Sometime a reflash of the firmware isn't enough to clear out custom settings. I do have similar problem with one of my computers, its ASUS Zenbook. No other computers or clients have any issue. My Zenbook drops connects to 2mbps and stays there for a while. It then gradually picks up again to 150mbps. In my case it wasn't enough reason to return the router. Is your experience is that all your wireless clients are dropped at the same time or is it just one ? Chances are if you have setup to service in mixed mode (b/g/n) and you have a b client it will bring your network to a crawl. Try eliminating all legacy clients by using n only.

I don't have a block diagram of it all but here is my setup:
