Wireless problems with Dell Lattitude E5430

Postby jsabin on Sun Feb 24, 2013 8:51 pm

I am running Linux Mint 14 Nadia on a Dell Latitude E5430. This same machine was previously running Windows 7 with no wireless problems. I love Linux Mint but I have a problem with the wireless. Every so often my wireless connection seems to hang up. Linux still claims that it has a connection but I can no longer browse or download patches, etc. Sometimes the connection seems to pick up after 30 seconds to a minute. Other times, I have to disconnect the wireless connection and reconnect. Can anyone please give me some advice?

Here is the mintwifi information:

* V. querying DHCP...

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the reload(8) utility, e.g. reload smbd

Sorry; I was traveling by the rainforest...

I am not sure if your wireless card works with b43 driver, test it:

Code: Select all
sudo apt-get install firmware-b43-installer


If it doesn't work, try the proprietary driver; download the driver and read README.txt to install it.

hi,

maybe this helps out.........

it might not be the card or its settings/peripherals, it might be the display!!! as foolish it´s sounds.........

I had also big problems with my new lonovo b590 getting and using proper wlan connections with isadora
in XP everything seemed fine

just after a smooth cleaning of the display my connection went straight from 30/40 percent to a 100% stable (even in my backyard!!!)

so you might just give it a try........


let me know if it helped you out!

Are you really suggesting just cleaning my monitor (like with Windex)? Are you saying that cleaning the monitor helps the antennae? If not, I don't understand what you are suggesting. Can you be more specific?
