I just upgraded my firmware from 1.0.13 to 17c and I noticed that the 5GHz wireless connection on my laptop occasionally disconnects and immediately reconnects on its own. Didnt have this problem with 1.0.13. Any setting I should be tweaking to prevent this problem?

Would you happen to be using a Macbook with that 5Ghz?

Is there a known problem with Macbooks? I am still on an earlier software version for the Router, as every newer one I tried was not stable, so I haven't risked 1.0.17 yet (Would affect my office)

Nope, not a McBook.... would also like to state here that the problem hasnt occured in a while. Will update if it happens again..... maybe it was just interference from other wireless routers in the area.

I just bought the RT-N56U and immediately upgraded to 1.0.1.7c and the 2.4 GHz band radio is dropping out periodically.  Using the Android WiFi Analyzer app, the RF drops have been seen once every 15 sec or at a regular 5 second interval.  The RF drops are from a steady -45 dB to >-90 dB and last for no longer than 2 seconds.

I had the exact same problem to begin with on my other laptop (2.4G) but I fixed it by using 802.11b only for communication (no g). This prevented the frequenct signal drops, but now I face the occasional disconnect on both 5G(b/g) and 2.4G(b). Interestingly the last time there was a disconnection, I noticed that when I checked the connection details, there was no 'b' band available and it connected the minute it picked up on the band.

I'm also noticing the bandwidth utilization being reported in the Traffic Monitor is not accurate.  I was running a 2 MB/sec download through the gig eithernet ports and it was only reporting traffic at around 6 KB/sec.  Not sure if the two issues are related but it too seems to work occasionally, but mostly it doesn't.

I saw another post regarding resetting to factory defaults after a firmware upgrade so I thought I would try that.  I reset to factory and just set the SSID and key for the 2.4GHz. band and so far so good, no drops at all.  If this holds it seems like there is an initialization bug in how ASUS handles firmware upgrades and resetting to factory does a proper initialization.

I'm also seeing the traffic monitoring function seems to only accurately report raffic that is selected in the EZ-QOS setup.  I couldn't see Netflix traffic until I set streaming video to get QOS priority.  Same with Xbox, no traffic showing until gaming was set as a priority.  Yet when all are turned off it does show some traffic, so this too seems buggy.  It should show all traffic, all the time so one can see the whole traffic picture not just bits of it.  Anyway, it is much better than before!

I did the same thing, it didnt help much. But I did update the 2200BG Intel proset wireless drivers on my laptop and it seems to have fixed the problem.... so this topic is not a router issue.

Hi Asus.

I'm having this exact issue and am indeed using two Macbooks on the 5GHz network. The N56 is updated with the latest firmware version (1.1.1.7f ) so that's not the problem.The issue occurs very regularly when a lot of data is being transferred in either direction. Under light load, it doesn't seem to happen frequently. Can you please help me resolve this? Listed below is a snapshot from the router's log. Once the problem starts, the log fills up with thousands of the "kernel: Qidx(1), not enough space..." error messages. Please let me know if you need any additional info. Thanks very much.

Dave
