I am using Aruba wireless equipment and facing an issue with HP terminals freezing for the users. Users have Wyse terminals. Other than trying to go through Citrix to get to HP instead of going through HP directly what else can be tried? Connection is dropping on end of coverage area for AP. Moved AP still same issue. Could this be a driver issue relating to the Wyse terminal?

Hey ...

I am not sure about Aruba. When you say coverage is dropping at end of coverage it means clients could not connect at low data rates or it is more than possibly near/far issue.

Try to move the client closer to the AP. Enable Load balancing on the controller.

Take a wireless packet capture and see if there are retransmissions, interference.

Aruba supports ARM. Try enabling it (sometimes disabling it resolves issues). Move the clients to a radio and see if it resolves the issue.

My 2 cents

Thanks.
