Cellular Broadband Adapter to Connect to Citrix

Are there any specifications of which I need to be aware in purchasing a cellular (Verizon) broadband adapter which will be primarily used to access Citrix?  
We have a user with a Verizon broadband card now whose connection is frequently dropped.  He also gets Insufficient memory errors regularly when using Word.  
The thought is that replacing the card may correct this issue?

I've never had any problems with my Verizon card with accessing Citrix via the Web Interface.

Which model do you use?

We have about 9 users with Verizon cards and none of them have any issues, other than some slowness when not in a broadband area.

The insuffiecient memory is most likely because of not enough RAM or the hard disk space to keep a large page file. Check the C drive and make sure you have at least a gig of free space, if you do then just add more memory, preferrably 1GB or so.

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

Do I want to change the paging size of the Citrix session, or of the local system?  This system is new and has an 80 GB drive + 2 GB of RAM.  
Which models do you use?

I don't have the card with me on this trip but I am thinking it is a 5750.

We have two Proliant DL360 dual 3.4GHz, each server has 3.5GB of RAM and they both have two drives with 14GB (M) and 42 GB (N) free. My own paging file is set at 4095MB and placed on the larger drive where I install all the programs to. We have had any memory issues, but keep in mind that depending on the issue, it might be a local client memory issue and not a server memory issue.

Hope this helps.

Ours definitely seems to be a local client issue as I can log into the same session and not get the errors, but if I shadow, I see the errors.  No one else reports these errors.  He only gets them when in Citrix and an broadband.  This is why I am wondering if broadband adapters have to have a certain technology to work with a Citrix environment.

Thanks for the specs on your servers. I was actually wondering which model(s) you use for the broadband adapters.

Would it seem feasible, then, to presume that, considering this user can connect to Citrix via a wired Ethernet connection without error, that this could be an issue with the card, but not the service?  Has anyone seen cards go bad and cause these kind of issues?

tropez9Commented:
Is this person in a NationalAccess area or Broadband when they have these issues?

I'm not ruling out the possiblity the card or service could be causing the problem, but if switching cards doesn't fix the problem, then perhaps you can at least have some other ideas as well.

It should be Broadband as it is usually at Starbucks in Westlake Village, CA.

What kind of a card does the user have? I know with the USB720, it sticks out from the computer quite far and can put some pressure on the actual USB port which has caused a slot or two to cause issues.

He's got a PC Card bus adapter - not sure of the model.  He is notoriously rough with equipment.  I believe these are hot swappable, though?  Perhaps if he did not disconnect before removing the card he might have an issue?

tropez9Commented:
If it is a Windows PC, then the card should be either ejected or the computer shut down before pulling the card out; I'm not sure if Macs are similar or not. If he is simply pulling the card out or shutting down without disconnecting properly then it could cause Citrix to eat up memory as the session would continue to sit on the server until your timeout. Ideally it would reestablish the session when he reconnects, but I know quite often my own environment doesn't do that properly.

I agree.  If I just pull my 5750 out Windows becomes unstable and when I shutdown or restart I get "memory access" errors on the card software.
