Thanks Johm.Nice I got a similar increase in speed, overall its well worth doing. If my memory is right the factory 802.11g card had two antenna connections, it makes you wonder why Acer never bothered shipping with two antennas as standard.
No changes are required, VG.8PG06.001 is a drop in replacement. Was the part new or used? Genuinely new ones are thin on the ground these days, occasionally I've picked up used VG.8PG06.001 that had the graphics BIOS flashed with something other than what the card ships with (for use in another manufactures system etc.) which caused the same symptoms. The VG.8PG06.001 graphics BIOS used on the cards I tested successfully was I think 60.84.62.00.29.
If it was used it could be worth asking the previous owner what system it was pulled from and if the BIOS was ever flashed, it could also be DOA

used, tested in fully work condition, with A-cer Bios
Is there anyway of checking/fixing the BIOS if that is the issue as opposed to DOA?
