iChat problems??

I have a new Netgear router because my old one died. From everything I can tell it is the exact same router I had before just brand new. Perhaps the firmware is different but I kept it updated so don't know for sure.

Basically what is happening is when I start iChat it will just sign in and sign out extremely rapidly until the account is temporarily disabled because I logged in and out too often. I click the icon and it logs in an out faster than I can count instantly then BAM the error message.

Have no idea whats going on. Don't have any other network at my disposal right now to try this on so I can't say if it is the router or a random problem with iChat. AIM works fine on my phone so I know it isn't the account.

I'm going to restart right now and then try 7 and see if the problem still persists but has anyone heard of a problem like this? Very strange.

My MBP is up to date software side. Made no new changes.

Edit: Works fine in Windows 7. AIM starts up without issue.

 

Log AIM on port 443 rather than port 5190.
IChat in the menu bar > Preferences > Accounts.
Log out of AIM and then use the Server Settings tab
Set the port to 443.

 

Ah. Thank you VERY MUCH. That was extremely annoying. Worked perfectly.
