I recently keep having the problem that my internet stops working. On firefox, I get server not found. And the usual make sure that you didn't type ww instead of www.

Wi-Fi is still connected. A restart always fixes the problem. In Skype, I get multiple messages with people going offline at the exact same moment. Is there a way to fix this so I don't have to keep restarting it?

$ lspci -knn | grep Net -A2
01:00.0 Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM57765 Gigabit Ethernet PCIe [14e4:16b4] (rev 10)
Subsystem: Broadcom Corporation NetXtreme BCM57765 Gigabit Ethernet PCIe [14e4:16b4]
Kernel driver in use: tg3

UPDATE:

It seems that Skype keeps fluctuating between everyone offline and some online. But it happens separately to when the browser stops working

I have a MacBook Pro with Ubuntu as a partition

  • Please [edit] your question and add output of lspci -knn | grep Net -A2 terminal command. – Pilot6 Jun 01 '15 at 14:17
  • Done. I also recently donwloaded broadcom wl because 14e4:4331 was not supported – John K Jun 01 '15 at 14:27
  • What is your Ubuntu version? Can you connect to internet by wire? – Pilot6 Jun 01 '15 at 14:30
  • No I cannot. My ubuntu version is 14.04 LTS (Trusty Tahr) – John K Jun 01 '15 at 14:31
  • No. I am not asking how to download the wireless drivers. I already did so. But the internet fluctuates between working and not working. Wi-Fi still is connected when it stops working. – John K Jun 01 '15 at 14:33
  • Your driver is not installed. That's why wireless works badly. – Pilot6 Jun 01 '15 at 14:34
  • It isn't? I went through steps of installing the driver and after that, Wi-Fi started working. And then it started acting strange – John K Jun 01 '15 at 14:35
  • Do it again. If there are errors, post them. It should show Kernel driver in use: wl – Pilot6 Jun 01 '15 at 14:38

Your wireless wl driver is not installed. You probably tried to install a wrong version that did not build for 14.04.

When wl driver is installed, lspci -knn | grep Net -A2 shows Kernel driver in use: wl

Install the driver this way.
