"Can't Access Yahoo Inbox"

~~George Quick~~ · 11-08-2005, 10:26 AM

I've just set-up a Home Office network, and one of the first things that has been discovered is that the e-mail functions have had problems.

Initially, once the Router was installed, the SBCGlobal Yahoo accounts would only open at the "Mail" page, but would hang when you tried to get into the "Inbox" (or any other sub-folder, such as "Sent Items", etc...).

I ran a Google search on "can't access yahoo inbox" and found this Thread/Forum:

http://www.freedomlist.com/forum/vie...er=asc&start=0

It's a very long thread, but basically what the problem/resolution is about is that there is a problem with accessing Yahoo (and possibly other) e-mail accounts with a router due to something called "MTU", and that the User needs to change these to "1492" in order to achieve normal e-mail operation while using a high-speed interent connection & a router.

I have no idea what any of these actually means, but I did the suggestion, changed my routers MTU setting to "1492" and my e-mail started working again.

Also, for good measure, I did several other suggestions at the same time, such as "ipconfig /flushdns", deleting the cookies and the temporary internet files. So I can't say for sure which "action" solved the problem.

The problem now is that accessing the e-mail account is "balky". Sometimes it still hangs at the "Inbox". (about 1 out of 4 attempts at accessing)

I am wondering several things. First, could changing the MTU again (either higher or lower, I can't say) improve the situation ?

Then I have a concern about degrading overall performance by changing this number. Can/Will it ?

Finally, I wonder if it is possible that doing the other actions may have been the actual solution, in which case would doing them again be benefical ?

This seems to be a problem which might be fairly common, so solving it completely may be of use to many people, in addition to myself.

Thanks in advance,

George.

Found the following link, which does a pretty good job of explaining what "MTU" is, and how it relates to everything else.
