Query: slow tech support

The VPN functionality does not work as advertised. I attempted PPTP but was not able to access LAN. Wasted many hours trying to get the problem resolved. Opened a case with Trendnet but they called me back in 4 days instead of the 2 days they promised. Once they do reply, they're not bad. One of the few companies that are still using onshore tech support (at least for the VPN part). The product guide is sketchy and does not contain problem solving help for this particular problem. The website has some FAQs but also does not address this problem. I managed to get the remote desktop to work. Still working with tech support on accessing the LAN. I nearly gave up on them. Let's see if they can get my problem resolved. They had me upgrade the firmware to version 2.
