What diagnostic information would you need to help me figure out why I keep losing my wireless connection? Thanks, Tom -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

A good practice to do in cases like this is to run dmesg -w in a console and see what it says when the connection fails. Furthermore: Is this PCI / USB? -- Gertjan Lettink, a.k.a.

PCI. lspci says it is an Intel wireless chip. Wonder if I need a firmware update. Not sure exactly which chipset it is, though, and how to update firmware on Linux, at least for wireless devices. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Then why not simply show lspci output? lspci -nnv

Pointless now, I found that it is an Intel Dual Band 7265 Wireless AC chip.

Some of those dual band chips have problems connecting and staying connected if you have a dual band router also. If so, try shutting dual band mode on your router and only run on 2.4 GHz (not 5 GHz or 2.4/5GHZ) for testing. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Interestingly enough, shortly before you posted this, I received an email from a colleague with this link: http://zeroset.mnim.org/2014/04/22/unstable-wifi-connection-on-ubuntu-14-04-... I am going to try this to see how I fare. Tom -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

So far so good with disabling 802.11n on my wireless connection. Will report back in a few weeks on the stability of the connection. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It looks like disabling 802.11n in the driver did the trick. I've had a stable connection for the last two weeks. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
