Model : TL-WR841N

Hardware Version :

Firmware Version :

ISP :

Hi all,

I have recently switched to TP-Link TL-WR841N wireless router. Since then my iPhone stopped receiving and sending emails via Apple mail app. All other functions work, also the email accessed via website works. I checked and there is no firewall rule on the port Apple Mail app is running on, nor there is any port forwarding.

I tried to set my iPhone to static IP address on my home WiFi and opening the relevant port for it, but with no help. It is not blocked by ISP - that I confirmed by plugging back my old router which made all the email go through in a second.

Could anybody please help? Thanks

Thank you Kevin,

Lowering the MTU to 1492 helped.
