Has anyone had intermittent or constant problems connecting to the internet since upgrading to Snow Leopard? I am trying to find the cause of the problem and I'm not sure if it's the Broadband provider (British Telecom) Faulty wiring (which has never been faulty before) or the fact I've upgraded to Snow Leopard as the problems occurred at the same time. I have had new wiring in the house plus a new router (BT home hub) but still the problems persist. The router switches itself off whenever I'm uploading or downloading any information. It can normally cope with loading web pages or emails, but as soon as the Macbook Pro switches on, it synchronizes with mobile me and that makes the router switch itself off. It does switch on afterwards, but the interruption not only upsets the sync but also the backup of my files. It is most annoying and as this problem started about the same time as I installed Snow Leopard, I'm trying to eliminate any issues to find the real cause. The system preferences refuses to accept a 'manual' setting for sync and the macbook continues to try to sync regardless of my attempt to stop it. So I've been unable to save files to backup with mobileme and sync my devices to iphone. If anyone out there has had the same problems as me, please get in touch. I've run the disk utility and Tech tool Pro but everything is fine according to these applications.

    Similar problems Jane,
    I am connecting and losing connection every few minutes. I use diagnostics to reconnect but it only lasts a short while. I have never had trouble before and still don't on my Power Pc and macbook booted in OSX 10.58, but 10.6.1 Snow Leopard will NOT behave. Browsing thru other mac related sites it seems the problem is a common one but have not found a fix yet.
    I cannot connect to my Airport it says password invalid even though it is correct. My Airport Extreme Base is the original one (Space Ship Shaped) I wonder if it is no longer supported properly by Snow Leopard, Any ideas would be appreciated since I don't really want to revert to 10.5 but may have to if cannot get a fix.

    Here are some tips:
    Try to switch off Firewall at all for some period to check if it is firewall settings. Sometimes Stealth mode creating this problem.
    About MobileMe - you need to try to reset your sync data on computer. See this link for follow up instructions

    Hope it will help,

    Here is a possible solution for internet connection problems:

    Go Finder > Your HD > Library > Preferences >SystemConfiguration;
    Move the SystemConfiguration folder to your Desktop;
    Launch you browser and with any luck you'll be online or online more permanently.

    Keep your System Configuration folder for a while just in case.
