As a result, I am gonna recommend to add more memory RAM to 4 GB. (what do
you think)

Questions:
1. Do I really need to add RAM to resolve this issue or I can get around it?
2. if I want to order memory Do I need to upgrade any firmware, reconfigure
the box ..or anything else?
3. How much will cost me the 2GB RAM, I need to care about the model of the
memory


Thanks
