Had Thiborc15 installed a few days ago and all was well. Then all of a sudden this morning, Outlook would not send email. The only thing that I changed since last night was setting Bittorent to "low". Did some reading and even tried setting MTU manually after a ping / % loss test. Still not sending. Also see lots of CRC errors (receive) and Frames retried (transmit) on the wirless adapter diagnostic. Not sure if this is related. Finally, I had to flash back to default linksys firmware and outlook is sending email again. I would love to continue ot use Thibor15c aagin. Can anyone help or share some insight as to why this might happen. It will at least give me some things to test if I decide to upgrade again. Thanks in advance.
