Upgraded a friend to Snow Leopard the other day. All was fine except that mail was taking 20-30 seconds to send mail. Finally isolated it to a router setting of some kind, as plugging directly to the modem resolved the issue. (The computer having trouble sending mail is actually a hard-wired desktop) However, when I plugged the router back in to set it up again and start troubleshooting, it would not save any changes. So logging into the router at 192.168.1.1 from the wired desktop, changing any settings, and pressing 'save' just brings up an 'unable to load page' Safari prompt. Has anybody run into this issue after ugrading to SL? (or to Leopard, for that matter?) I believe it's a Linksys WRT54g wireless router.
