Can't send documents from Lotus Notes with a Linksys Wireless B ver. 4

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 doubt it is your adapter.... if you can connect that is really all notes cares about it uses port 1352 to communicate and it cant differentiate what the traffic is (i.e read vs compose) so if you can read your should be able to send.  This assumes using a notes client.  Hmmm just had a thought ... your client could be set up to send mail driectly to the internet rather than through the mail server.  lemme check on the setting in the meantime...

When you say you did a complete update overwrite to your laptop what are you referring to?  Notes has replication, update overwrite is not a common term in the Notes world... describe what you did.  Are you getting an error when you try to send (if so what is it ) or what happens ?

Are you using the client or web mail... the web mail in R6 requires java to do anything other than read and you have to accept the download form IBM at the begining.  This could also be blocked from the firewall or even in your browser.

If you are using the client do you have a local mail replica?  Also the Access control list could be set to reader on your mail file check by right clicking your mail file and choose access control and highlight your name ... it will list your access.

Sorry for the double post

If you check your location document... go to the bottom right hand corner on the frame where it probably says office (or home or mobile)  and click on it.  It should give you an option for Eddit current.  click that .  Go to the mail tab and check what it says A) next to Mail file Location and B) next to Send outgoing mail.

If B is "directly to the internet" change it to "through domino server" and try that... you may need to restart notes.

If A is on local then you might need to go to the replicator tab to send the mail out.  

If none of these help try to be a bit more specific about what happens when you send mail... do you mean send or do you really mean create? And do you get an error or what happens.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Thank you so much for all your help.  I actually posted this question under VPN and someone helped me solve it.  I changed my MTU on my laptop to 1386 and re-booted and was able to send mail!!  Thanks again for all your help.

Just out of curiosity what is the setting in your Location document I mentioned above.  My guess is from your answer that it is

Send outgoing mail                     "directly to the internet"

No - it was set to "through domino server".  This is a work laptop and when our corporate office does updates - they just send us a new image and we replace the C drive with the new image.  It just means that I have to re-program everything all over again (and if I'm not smart enough to hotsnych my palm - then I lose all my information off my laptop and then to my horror realize my battery on the palm is gone...)  To get Linksys Wireless B v4 to work - I had to load a beta version of the drivers from Linksys and change the MTU to 1382.  The beta driver site was:  ftp://ftp.linksys.com/beta/ and the site to change the MTU was:  Dr. TCP tool available at www.dslreports.com/drtcp.  You select your wireless card at the bottom and change the MTU value to 1382.
Linksys was unable to help me with any technical support.  In fact - the support is outsourced to India and I had a hard time understanding them.  When I first installed the Wireless - it took 6 hours to get the Beta site out of them.  That's where I started this time!!  

Thanks again for your help!!

My pleasure ... glad its working.

But maybe you can school me a bit here ... how does that setting prevent you from sending mail?

Not sure I can tell you much.  I know that Lotus notes seems to be sensitive to the MTU setting.  I am not a techie - so I don't even know what the MTU is!!  I just know that I have searched high and low for the solution to this problem and have seen the MTU setting mentioned more than once.  Here is the discussion stream that gave me the answer:

Good luck!

MTU=Maximum Transmission Units, the largest piece of data your computer will try to send in a single shot (packet).  Between your computer and the server you are trying to reach, there may be many waypoints (routers), each of which has its own MTU.  If you MTU is larger than a waypoint MTU, that router will have to take your packet, break it in two, and send it as two pieces.  That's called packet fragmentation.  Because of the way TCP/IP sends acknowledgements back and forth to make sure it didn't lose a few of the packets that make up a total conversation, and pieces all the packets together into a complete conversation, packet fragmentation does two things:

1) Slows down traffic
2) Makes it more likely that part of a conversation will be dropped, requiring it to be resent

Put the two together and you have a slow connection that constantly needs to be reiterated.  Eventually, unless tolerances are very high, something will give.

Now, you have one MTU, your Domino server has its own MTU.  If your MTU is too high but teh DOmino server's MTU is OK< then you can get data from the Domino server, but will fail when you try to send data to it.

Unfortuantely this seems to be a notorious issue with VPN. I don't know why. Personally I always have difficulties if Novell's BorderManager is involved. The network admins always tell my that everything works fine until I tell them about potential MTU issues with Notes. Then they change something and it works.
