Wireless in Gentoo on HP2140

Published:

The last time I was tinkering with Gentoo on HP 2140 there was a problem with wireless and dhcpcd. Today I found a fix at the Gentoo Forums.

As it takes a while to compile the kernel if you have not optimized it well. I have not so when you compile, it is a good idea to take a cup of coffee or if you prefer, a cup of tea.

After adding these as modules in the kernel you are probably safe to go. Remember to use ACCEPT_LICENSE in /etc/make.conf for broadcom-sta. As the author says;

“Re-emerge broadcom-sta and it should work with Network Manager.”

When I compiled broadcom-sta I got some error about a few entries in the .config file. Just comment them out and recompile, after that it should work fine. The entries I had were

  • CONFIG_B43
  • CONFIG_SSB
  • CONFIG_MAC80211

Previous configuration with Gentoo on the HP 2140 can be read in “Gentoo on HP 2140”. Best of luck to you. After all it pays off to have a snappy machine when you put some effort in it.
