Is there a problem with the Optimus V wireless card, the native Intel one as people on here seem to advise to get the killer wireless. Should I get the killer wireless for £20 more or is the Intel one good enough?
If you're asking before you order I would get the Killer card. Many people have had problems with the standard Intel wifi card (including me). If I was ordering again I'd go for the Killer card.
They're cheap so quality is probably hit and miss, plus those with cheap wireless cards are likelier to have cheap routers and such, exacerbating the problem.
