The TR5B has English XP Home Edition installed and is using Lan-Express AS IEEE 801.2 a/g miniPCI adapter(driver version 3.1.1.54 downloaded from sony japan) which support a/b/g mode. but I have only one tick box of “Enable 2.4Ghz Wireless Lan” under wireless lan setting of sony’s own wireless device switch utility. shouldn’t there be an “Enable 5Ghz Wireless Lan” option?
Please help.
