I have a NetGear wireless usb receiver in my desktop, that connects to my router (tried both DLink and Belkin) prefectly fine, however will simply disconnect after minutes, 10s of minutes, a couple of hours (no real pattern) at which time I will need to unplug and reinsert my usb receiver and reauthenticate to the router.

It appears to be happening alot more frequently when the pc is left unused for a while, and goes to the screen saver.

This has been hapenning on 10.04 and 10.10 (gnome) (and possibly 9.10 as well, though I have updated my gear since then)

Rather than expect someone to give me a magic bullet solution (that I'm happy to get :) ), as a novice user, what should I be looking at to troubleshoot this?

I have looked at this question already, and to my (limited) understanding, don't see that it addresses the issue, unless there is someway of ascertaining what chipset it used.


Looks like there are 2 drivers for the WN111 V2, the first does not support N routers, and the second is 'N speeds not verified'. I may have to shop around for a better one :/


Have you consulted Community Documentation?

  • Just the sort of thing I was looking for, thanks – johnc Oct 19 '10 at 21:37

I use IwScanner to figure out channel usage in my neighbors, and my access point power in different location in my apartement.

Anyway usual check could be :

  • Bad wireless phone can disrupt wireless connection.
  • Reinforced concrete wall / wiring configuration could block the signal.

Other than that you seem to point to a driver bug, then we could get more informations with the chipset of your usb adapter, and then dig deeper into the issue.

  • Nice tool, thanks, it shows a very consistent signal. – johnc Oct 20 '10 at 8:59
