I have a Lenovo with a AR9485 but I don't have any close neighbors with wifi and your channel and regulatory settings are the only issues I saw. I'm wondering now if I could possibly have anything to do with my wireless mouse, which also operates on 2.4GHz. I've also tried upgrading my kernel to Linux 4.0 but the problem persists.Įxact chip: 02:00.0 Network controller : Qualcomm Atheros AR9485 Wireless Network Adapter (rev 01)ĭriver: $ ls /sys/class/net/wlan0/device/driver/module/driversĬfg80211 540672 4 ath,ath9k_common,ath9k,mac80211 I have tried passing the nohwcrypt=1 to the driver, but that made it impossible to connect to any AP, it just infinity attempted to connect. Is there anything I can do to make the connection more stable?
I've been able to get it working again by simply disconnecting from my wireless AP and then reconnecting, but this is annoying. The indicator in the top panel will still say we are connected but the machine has no internet connectivity whatsoever. So far it has been working ok except this one issue: Randomly (as far as I can tell) it will completely lose the internet connection. It could extend the life of the router, and at least extend the life of the RF section(s).I recently bought a new computer that has an Atheros AR9485 wireless NIC. Here are speed test results all at the same location / time / destination, the only thing different is the wired / wifi / bandwidth:Īnother benefit of running low power on your wireless router is to reduce the heat generated, and held in the router. Sometimes you might want to bump up the power to reach out to the front / back yard, but 99% of the time lowest power / bandwidth is more than enough. What it all ends up coming down to, is how much performance can I get at the lowest RF/WiFi foot print.įor most of us, running the lowest possible power is more than enough to connect in our limited space. Here is what the Channel Bandwidth at 20mhz looks like: You can see how huge the 40mhz dlink channel is compared to everyone else - it is walking all over their channel - 20mhz would be more friendly/neighborly

They also have an Android release version. Home site, inexpensive, new - what I use: You can look at your wireless landscape by using something like inSSIDer to see local AP's:
In a clean wireless area, I might keep it at 300mbps just for fun
My Internet connection is 50mbps, so there is no performance difference between 144mbps and 300mbps, so I run 20mhz here. That is why I reduced my power output to 10mW - I don't need more. If you don't need the wide Channel Bandwidth to get your work done, ie: it doesn't help performance, you could force it to 20mhz - and reduce your interference with others near you. Pale Moon, good news, when I first connected at 2.4ghz it connected at 144mbps, but after tweaking the Channel Bandwidth from 20mhz/40mhz to 40mhz and it connected at 300mbps at 2.4ghz.Īt my location there are a gazillion 2.4Ghz AP's, so I don't even bother with 2.4ghz, and go straight to 5ghz, and even there I need to place my signal center carefully. My Tx power adjustment i 80 mW by default though. option in my channels, only 20/40.since i'm on the 2.4 Ghz. My settings are almost like yours, except my WLAN Atheros doesn't support 5 Ghz.
