HI this is very weird, I upgraded my DSL box from the Westell 6100 to the A90-750015-07 wireless gateway/router ad now I can maintain a VPN connection. It connects to my VPN company (SAP) and then disconnects right away. I have tried wirelessly and wired both the same result. This was never a problem under my old DSL box. I spent 2 hrs on the phone with a Technician and they ended telling me that it was on my companies VPN side, but i never had any problems before and I've had Verizon for 4 years now with no problems. I also upgraded my package from 768kbps to 3mbps. I just may have to return this new router and get refunded. Does anyone have any solution to this problem?
