Ok, so delete the line or try another antenna.
If you're having poor signal, are you on 2.4GHz or 5GHz? 2.4 tends to have way, way better range.
Tried all the antannae, ended up reinstalling Ubuntu.
It's not like the wifi didn't work, it was just a weak signal.
Why the fuck do computers have so many antannae?
I'm not completely sure but betting different antenna for 5GHz than 2.4GHz.
Again, figure out if you have 2.4 or 5. If it's 5, make it 2.4. Probably problem solved.
At the AP the antenna should be straight up and down if external, although that probably only matters if your antenna in the laptop is straight up and down.
It should pick the antenna by default. You probably don't need to mess with that. No real tweak you can likely do other than making antennas bigger or raising power levels.
Which model HP?
