Connection to mail.comcast.net has been reset
Using Thunderbird email I get the above error message multiple time a day when checking email. They only way for mail to work again is the turn on/off Airplane mode, switch wireless band (2.5 to 5 or visa versa).
This has been happening for the past 2 months now. It's is not a Thunder bird issue as MS Outlook has the same issue! Here is the Outlook Test Error when the problem occurs.
I have tried incoming servers, imap, pop3, mail.comcast.net and all have failed.
Again, MS Outlook and Thunderbird has the same problem when they can't connect. Switching bands, Airplace mode off/on, all comes back and works... for a while. Maybe 2-30 mins later the problem occurs... unable to check and get email.
