Can't send mails in Mountain Lion, Safari doesn't open all webpages

[zidhjian]

Hello,
I upgraded yesterday to Mountain Lion, but im having a few serious issues.
Mail: I cannot send emails, I have one work account two gmail accounts, but none of them can reply to any mail that I have received.
Also, safari doesn't open pages where I am trying to log into. For example if I try to log into my Gmail account on safari it jus't says either: "Request Timeout The server timed out while waiting for the browser's request.
Reference #2.7baf9559.1343320900.0" or "Safari can't open page because the server where this page is located isn't responding."
I also can't get into apples own support forum, Safari times out there aswell.
Also I cannot post anything on this forum either, I started this thread on my iPad wich is in the same wifi network as my computer.

Anyone have the same problems?

Zid

Request timeout
The server times out while waiting for the browsers response

Same thing

I am getting a similar thing, ironically if I enter "apple.com" into safari it times out, Chrome is fine.

Also having issues accessing iTunes store - anyone found any solutions?

Thought this may help, an issue as above with two machines, flaky web access especially where you need to login to a site, itunes not quite connecting to store.

Tracked the issue to MTU value on wifi card, reduced from 1500 (default) to 1400, has solved the issue.

I recommend you create a new location in wifi preferences and setup from scratch with the right MTU.
