Random Disconnect Question

[J.T.]

Hi I have a AC68U router. I have a problem I have been wrestling with for months now. My Dell 5323 will randomly disconnect for about 45 seconds and then reconnect on the 2.4 band (my laptop doesn't have the 5 ghz band). This happens every 10 minuets or so...

I have played with every setting I can think of and the problem persists. I have reset to factory defaults in hopes one of you can help me. The only option that seems to help is disabling airtime fairness on the 2.4 band. Still happens but no where near as frequently; maybe disconnects every 45 minuets or so...

Also if this helps, if I disable the N mode on the wireless card thru Windows, the problem goes away. This does not happen with my old Linksys or Netgear routers and I tried a new Asus rt3100 router and no issues either.

The card that is in my laptop is the intel centrino 2330. I have updated the drivers and same issue. Help!

No ideas y’all?

The 2.4 GHz band is very susceptible to interference from USB 3.0 devices and Bluetooth. Look for any possible cause of interference, especially if the issue seem to happen on a timed cycle.

Also, the Centrino 2230 is a bit old, maybe it's just starting to die on you.

Disable Airtime Fairness and set 2.4 to 20 mhz bandwidth on channel 1, 6 or 11.

I tried everything in the world and I never could get the problem resolved. I had to upgrade to the AC86U.

Strangest problem ever! Cost me $200 for the new AC86U.

Dell drivers suck (or they hate ASUS routers.) and turn off the dell driver update once you fix it. I had a user with a dell complaining about disconnect the fix was to go to wireless network manufacture site and use that driver. The problem would creep up every so often and turns out the dell update would pull dells driver back down.

I actually tried both the adapter driver from Dell's site and several from the Intel site. Same strange problem. I worked in IT for years and still couldn't figure this one out.

So I have two perfectly good AC68U routers collecting dust, as they both had the issue.

My new AC86U works like a top.
