I've recently bought a second hand TSI6400 from ebay .....
The problem is the unit took about 20-30 mins to boot and load configuration file, but the thing is the unit does not has any .....

Second problem is, from the configuration menu, the wifi strength status is always showing zero and cannot detect get ip from my dhcp wifi router.

The RF icon is not showing in the battery status display.

Any ideas to solve these problems will be helpfull
