Wireless not working - Please help

[thrainpa]

I have a Dell 15r N5110 which uses Intel Centrino Wireless-n 1030.
I am using Ubuntu 12.04.

The problem I am having is that I can successfully connect to my router via the card, but when I try to load up a webpage (say, google) it just doesn't happen and when I check 'connection information' is says the speed is 1Mb/s .

Can anyone help me fix this?
What other information might you need from me?

P.S. Apparently this laptop is 'approved for ubuntu', I think not. >.>

Please post output of:

inxi -b

and

lsmod

[thrainpa]

inxi -b does nothing.

lsmod gives:

However, by disbaling 'n' in iwlwifi I have managed to get it to work.

Is there a way of getting it to work WITH 'n' channel?

[Carl.Spackler]

Strange 'inxi -b' did nothing...

Maybe you can it to work with N.

Is this i386 or X86_64?

also please post to give us info on the iwlwifi module:

modinfo iwlwifi

[thrainpa]

X86_64

Is this on battery and while plugged in that it slows down with 'N' enabled?

Have you check this out?

You might also check out Jupiter for laptop power management if the power management ends up being your problem. I have it installed on my laptop and it made a large difference in battery usage as well as overall performance and I know that it has wifi card power management options when used.

I have a Dell 15r N5110 which uses Intel Centrino Wireless-n 1030.
I am using Ubuntu 12.04.

The problem I am having is that I can successfully connect to my router via the card, but when I try to load up a webpage (say, google) it just doesn't happen and when I check 'connection information' is says the speed is 1Mb/s .

Can anyone help me fix this?
What other information might you need from me?

P.S. Apparently this laptop is 'approved for ubuntu', I think not. >.>

Sometimes iwlwifi gets confused when it has to deal with "G" and "N" modes at the same time. This will be just temporary (until the next reboot) but try.

sudo modprobe -r iwlwifi
sudo modprobe iwlwifi 11n_disable=1

If it helps return and we will make it permanent.

What if it's just a minor configuration issue (seems more probable to me) rather than a hardware one, like no DNS or gateway...

To verify that, please post outputs of (while the wifi shows as 'connected'):

ifconfig
iwconfig
cat /etc/resolv.conf
route -n
ping -c4 google.com
