I am starting a new thread on this issue so that public should easily get the solution on very first page.
First of all let me clear something. I have read many forums on this issue but surprised to see no one got that simple technique, and the experts opinion is always that don't worry, its normal and it cause no harm. But I think its not true. Two major issues with internet devices are heatup and regular disconnection problem. After observing few EVO devices for over 2 months, i came to the result that constant heating of device causes the disconnecting problem.
SOLUTION:
I have bought Evo wingle + 12v dc fan(Rs.50) which is commonly used in computers and easily available on computer shops. I connected the fan wires with one of the extra power cables provided for hard disks and optical drives. I have removed one side cover of EVO wingle and set the fan throwing air towards the device. (If you cannot connect the fan with power cable yourself, let it done from any computer repairing shop, it costs Rs.100 maximum) The result was outstanding, even after use of 5-6 hours the device gets only little warm and working perfect. No signal drop, no disconnection, no problem at all. You can also use this technique for DSL modem.
Looking forward for your feedback/suggestions/questions.
