All of a sudden some emails won't work

[Sassyblonde91]

I have model WNDR4500v3.  I ahve had it for a year.  All of a sudden today - 2 of my emails will not work. I can receive internet fine, yahoo and gmail work, but the other two do not.  I have narrowed the problem down to the browser.  I have reset it a few times, reset my computers, etc. Does not help.   The emails work fine on my iphone if my wifi is turn off on my phone. 

I have tried everything!  Please help!

if these use port 25 I would contact ISP to be sure they're not blocking port 25

[Sassyblonde91]

They are using ports 993 and 143

try resetting the router

[Sassyblonde91]

I have reset it a number of times.  Does not make a difference.

have you tried a factory default reset

bypass the router and see if it works

[Sassyblonde91]

I did that - yes it works great if I by-pass the router.   So that tells me it is indeed a problem with the router. I just can't figure out what it is.

Also to make things more tricky - I can access then email if I use web login, but not through my apple mail app on my imac or microsoft office on a PC.  I have rebooted both computers to no avail.

A person with with 4 e-mail accounts should have a spare router. Try replacing the router.

 trying using same MAC Address of computer that worked when you by-passed the router. log in to router setup...Internet setup...select use PC MAC address.

This would insure that your Public IP is the same as it was when going direct sometimes IP's get blocked for various reasons.

Good Luck!
