I'm using a wired router connected to a ADSL line to conect my computer to internet, When I try to access using Firefox it gives following error,

Secure Connection Failed
An error occurred during a connection to
SSL peer reports incorrect Message Authentication Code.
(Error code: ssl_error_bad_mac_alert)

Internet Explorer does not load the page nor gives any error.

Tried setting Time in Windows and Router Configuration as sugested in some forums, also tried using a different router and different OS (Windows7 and Windows XP) but no avail, but worked perfectly when using a dongle (different internet connection) insted of the LAN.

Any suggestion that I can try to fix this issue?

There were apparently Gmail service issues on 4/17. Is it still a problem? – uSlackr Apr 18 '12 at 12:09
@uSlackr Yes, Now its working fine.. :) Actually Problem was there for about 2,3 days. Should be a problem with Gmail service as you said... – Nalaka526 Apr 19 '12 at 2:19
Now the problem is gone, Thanks everyone for Comments and Answers.... – Nalaka526 Apr 19 '12 at 2:20

This is happening because your browser cannot open https sites, I believe. Try changing browser or updating it; might help.
