I've got a 2.16GHz Intel Core Duo iMac running 10.4.9 and possibly the slowest wireless internet connection possible.. The modem/router is a Netgear DG834N and I downloaded the £1.25 N upgrade from Applestore. BT supply the ADSL. The odd thing is, my Vaio is fine connecting to the net, although not at N speeds, but the iMac is really slow - eg 5 minutes to load BBC homepage. It works fine with an ethernet connection (involves lugging the iMac to the other end of the house). The DNS server box is empty in TCP/IP and the software and firmware are all up to date so not being that brainy I'm a bit stumped... Any ideas would be great.
