I have a Dell Latitude E6400 laptop and my wifi is extremely slow, it takes ages to load some pages not to speak about videos. All other devices on the same wifi have proper internet speed

This is the output for

sudo lshw -C network

*-network description: Wireless interface physical id: 2 logical name: wlan0 serial: 00:23:4d:b3:4d:ba capabilities: ethernet physical wireless configuration: broadcast=yes driver=b43 driverversion=4.10.0-30-generic firmware=666.2 ip=192.168.0.31 link=yes multicast=yes wireless=IEEE 802.11

Output for iwconfig:

enp0s25 no wireless extensions.

Please help, I tried loads of tips from the internet, but still no improvement.

I also read a tip about using wicd but it is not showing my wireless connection....

I have the exact same setting (BCM4322 and 1510 Wireless-N WLAN Mini-Card) and I had the exact same problem.

I hunted a bit around and what seemed to help so far was to reinstall the related kernel modul:

sudo apt-get install --reinstall bcmwl-kernel-source

I hope this helps.
