This means its always going to be slow.
There are no returns after 21 days.
I would request you to drop me a message when you are ready to continue troubleshooting. Also, I would like to know does it happen on any particular application or after a certain period?
If you don't get back to us in the next 24 hours we will archive the case. The case number is 44135642. If in case you need any help in the future just drop a message and we will be glad to get back to you.
I see that we have done all the troubleshooting and it looks like a software issue and the Hardware looks fine.
I would request you to contact our Advanced software team 800-288-4410 which is a paid support as our scope of support is limited.
