Ok, I use Mozilla,

I have not changed any settings on this bit of software since I set it up, and it has been running fine for well over 7 months.

All that has happened, is that I have moved my computer upstairs in my house, and have had a few issues with the wireless hub. I was not able to get on line without a fight. Now I can get on line, and I can receive emails, but can no longer send them out.

What other info can I give, as once set up, I don't tend to fiddle, so I don't know what else can be done.

Will uninstalling and reinstalling Mozilla clear this problem up.?
