Linksys Wireless and VPN

I have a Linksys Wireless B Notebook adapter V4 and I am connected to Work Lotus notes through a VPN.  I am able to receive and read email - but can't send.  I was able to use Lotus notes last week without a problem - but on Friday - did a complete update overwrite to my laptop.  Nothing has changed on my router set up - what has changed is my laptop configuration and the fact that I downloaded a beta version of Linksys Wireless because I know from past experience that V4 doesn't work with VPN.  Any ideas??  Linksys is absolutely NO help at all..

I do not believe this is a Linksys problem.  Typically, a VPN does not block any ports or functions.  It usually is all or nothing...  If you are connected and receive mail, then I think it has something to do with the Lotus Notes instead.  Probably a configuration issue.

I'll focus on the Lotus configuration files instead.

When I dial up - I am able to both send and receive.  This says to me that it isn't in Notes.... Takes me back to the router being the issue.

Thank you all for your help.  I figured it out.  I changed my MTU on my laptop to 1382 and I can now send mail...

I recently had a problem with a Linksys Wireless-B adapter and a Symantec Enterprise VPN client. They were incompatible and had to replace. Replaced with a Wireless-G and everything worked fine.
