Wireless randomly disconnecting?

I have been noticing that my m17xR3 likes to randomly disconnect from my 2.4Ghz and 5Ghz network on my Linksys E4200. I have tried everything that I could think of to fix this, but it just loves to disconnect at the worst times. I've tried the Dell drivers, latest drivers direct from the Killer Wireless website (even their beta ones) and it still disconnects.

I'm not sure if this will help, but this happened to all of my Alienware computers (m17xR1, 4 m17xR3s with DW1501 and my current R3 with Killer Wireless 1103) and over 2 different wireless routers (Netgear WNR1000v2 and the Linksys E4200), while other computers that I have (an old acer and sony) do not disconnect at all.

All the other ones only disconnected about once a day, and all I had to do was restart the computer and it was fine, but this one does it 5+ times a day and restarting it doesn't always work.

Thank you for your help!

I have a similar problem, m17x R3 Killer Wireless-N 1103:

Approximately every hour or two, the adapter will disconnect from the network. It is not "disabled", just disconnected. I go into my Network Adapters page, and can't affect the device in any way: Disconnect/Connect does nothing (no network selection popup), Disable device does nothing (device stays 'enabled' but 'disconnected')- for all intents and purposes, the device is just 'stuck'.

I'm researching this issue as we speak, will update if I find any solutions.

 

That is odd, I also am using the same combo 1103/E4200, and I have no disconnection issues at all.

 

Now this is starting to get really weird, it's connecting to the 5Ghz network fine (for now), but it still disconnects from the 2.4Ghz

 

I have one question - what kind of wireless protection are you using? WEP, WPA, WPA2-PSK/AES?

 

Same thing was happening to me with a specific driver, I can't remember which one (dell or bigfoot) but the one I have right now doesn't have the problem. My driver version (taken from device manager) is 9.2.0.318 if that can help a bit.

To be noted that I extracted the driver from the installation so I didn't had to install the software, but the wireless was working fine with the software too.

 

I'm using WPA2/WPA Mixed mode on the 2.4 and 5 Ghz networks.

Those are the same drivers that show up in my Device Manager, and it connected to both of the networks just fine today.

 

Same issue here, using a Speedtouch 516 router at home. Get's really annoying when connected to work using Cisco VPN client and Remote Access as it seems to happen every matter of minutes. The connection re-establishes by itself quickly enough but I need to reconnect and re-authenticate the VPN manually each time.

Using WPA-Personal, WPA2-only, AES, mixed 802.11g/n, 2.4 GHz band. Will try to dump the Bigfoot Killer driver and use generic Atheros ones, and maybe 5 GHz band at the router (my Internet connection is shared with others so I'm not sure if this change will break the others' connections...).

Any other ideas?

 

Atheros bro, you need to install the atheros drivers
