I am currently traveling and have not had problems running my MacBook Pro on any other networks; however I am trying to use an ADSL connection at the hotel and the speed is painfully slow. When the tech looks at the speed of the network on a PC it is fast but for me loads at 58 kbit/s. Is this an issue with Lion? Any ideas on how I can fix this as the techs here do not know anything about Macs? Thanks!
