I bought a TSI6400 from ebay, but i'm not sure how does it work. The manual is too brief and there's hardly any good support site for this particular model.
My problem is:
1. It takes about 20-30mins to boot or load configuration file
2. The panel cannot detect any WAP or the wifi strength is always zero.
3. RF icon does not appear on the battery status display.

The unit is running on firmware 1.5.3.

Anyone can help me out ? I'm totally lost here.
