When solution 1 failed, I tried solution 2 as shown here below lspci -nnk | grep -iA2 net If no file exists, create a new file gksudo gedit /etc/modprobe.d/nfĪdd a new line: options iwlwifi 11n_disable=1 sudo gedit /etc/modprobe.d/Įdit the line that says options iwlwifi 11n_disable=1 Look into /etc/modprobe.d whether there are any file like nf then edit the file. Now try to reconnect, if it helps follow below steps
Looks like this hardware has some problem with N configuration in WiFi. conf file and edited it as directed in the last part of this solution but it didn't work and I was unable to go beyond that I had read a solution that was giving the steps below if I had succeeded. I find the file nf~ and try: /etc/modprobe.d$ sudo modprobe -r nf~ Then I go back to the /etc and try $ cd /etc Here I find the directory modprobe.d but modprobe does not exist so I try $ cd modprobe.d This so what I have so far done and the answers I get $ sudo modprobe -r iwlwifiįATAL: Error running remove command for iwlwifi I have tried out some of the solutions suggested but it still doesn't work. It worked well for a few weeks and now won't work anymore although it still works for the windows. It could extend the life of the router, and at least extend the life of the RF section(s).Hi I recently installed Ubuntu 13.10 on my laptop alongside windows. 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.
